I can successfully compile the example in 084 branch in of084. However I get the following compile errors in 090 and 092...

I'm working to display several videos overlay each other.
I draw the background and the front mask in ofApp.cpp and they goes smooth.
Between them, I draw some videos which is called by another class, they are correctly drawn between the background and the mask.
However, those video are just black boxes but not an video with alpha.
It worked before I try to apply an shader which I added ofSetCurrentRenderer(ofGLProgrammableRenderer::TYPE);
into main.cpp.
I have also tried to draw the video in ofApp.cpp, and it works.
Anyone have idea how to fix it? Thanks!

(I'm working on OF 0.8.4 with OSX El Capitan)

If I run one of the demo 480p hap videos I found online in the example, my CPU shoots to around 100-120% CPU usage according to the 'top' tool.

Running the same video through MPV uses around 18% CPU.

I tried converting the same file again using FFMPEG but got no benefits.

Any tips to get better performance?

Not really an issue per se, but more of a question: have you done any work on, or know of anyone who's been tackling, an AVFoundation-based Hap player for OF?

Hello,

I've tried using the same Hap file with audio which worked with 0.9.8 on macOS now with 0.10.0 and it doesn't work. When loading the movie the console says:

kAudioUnitErr_TooManyFramesToProcess : inFramesToProcess=1024, mMaxFramesPerSlice=128

When trying to play the movie the console says:

[warning] ofRtAudioSoundStream: stream over/underflow detected

Has anybody got audio to work with OF 0.10.0?

Greetings.

If you play a movie and use getCurrentFrame() then the movie framerate get progressively slower until the end of the movie. For a movie that's 130 sec long the rendering FPS goes from 700fps at the start of the movie to 30fps by then end. For a 10min movie it gets much lower to the point of being unwatchable.

This has been tested with ofx 0.8.4 and 0.9 under both windows and osx using both glut and glfw for the windowing toolkit. The easiest way to reproduce things is to add the below line to the example and swap the example movie for something a bit longer.

ofDrawBitmapString("Frame: " + ofToString(movie.getCurrentFrame()), 10, 45);

Sometimes you only want a part of the frame in a texture. We should vend textures with parts of the frame.

Hello,
After playback of a 2-minute HD file with audio I'm seeing it crash:

Thread 1: signal SIGTERM

function:
ofxHap::AudioThread::~AudioThread()

line:
_thread.join();

This is on macOS 10.12.5, Xcode 8.3.3
Any ideas?

The first one, i try to load a hapq video and it doesnt load. A normal hap movie is playing fine. Do i miss something?
The second question is, i could get it running on mac os 10.11 and with of 090 but i need hapq in a 093 project. I got a lot of Linker errors. I also tried to change build settings to 32bit without success.

When loading new video file into the same "player" object, there is "videocard/texture glitch" at the beginning of the movie:

https://vid.me/Q4U8

System: VS2012 Win8.1 oF0.8.4 default ofxHapPlayer example:
PS. used OF_FULLSCREEN and video was stretched to ofGetScreenWidth(), ofGetScreenHeight()

player.draw(0, 0, ofGetScreenWidth(), ofGetScreenHeight());

Hi!
I am trying to apply a shader to a texture from a Hap clip.
ofxHapPlayer player;
ofTexture tex;

setup()

player.loadMovie("test.mov");
player.play();

update()

tex = *player.getTexture();

draw()

tex.draw(0,0).

That works OK, but when I set tax.draw() inside a shader.begin()/shader.end() block it does not.
Using ofVideoPlayer and getTextureReference (without *) works OK. Any idea?

Edit: I can bypass it drawing to a FBO first, but doesn't look like a neat solution.

My shader is really dummy, does nothing...
.vert

version 120

extension GL_ARB_texture_rectangle : enable

extension GL_EXT_gpu_shader4 : enable

void main() {
gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
gl_TexCoord[0] = gl_MultiTexCoord0;
gl_FrontColor = gl_Color;
}

.frag

version 120

extension GL_ARB_texture_rectangle : enable

extension GL_EXT_gpu_shader4 : enable

uniform sampler2DRect texture0;

uniform float time;

void main(){
vec2 pos = gl_TexCoord[0].xy;
vec4 color = texture2DRect(texture0, pos);
gl_FragColor = color;

}

It looks like the new player is still working in the background when it is paused. I discovered this because I migrated a project to the new libavformat-player, where I pre-load 10 video files. Only one file is playing at a time, but every time the previous file is stopped and a new file starts playing, the frame rate drops increasingly.
I tried to only call update() on the current player, but not luck.

Im getting the referenced error message when compiling the library within a 0.9.8 OF project.
The function throwing the error is within the windows quicktime version 6.0.2, process.h

EXTERN_API( OSErr ) GetProcessInformation (const ProcessSerialNumber * PSN, ProcessInfoRec * info) THREEWORDINLINE(0x3F3C, 0x003A, 0xA88F);

Hello,
I would like to use the addon for one of my projects, and would like to ask if there will be an update version for oF v0.9 please?
Cheers,
Karen

Hi,
i've got some issues with HAP-alpha video's that do not play correctly:

• Alpha channel is not displayed correctly
• setPosition/frame show weird behavior

Recoded the video in hap regular and it worked correctly.

(using 084, vs2012 & Hap QuickTime Codec version 6)

Thanks!

Hello,
I'm trying to run the example for ofxHapPlayer > libavformat branch on openframeworks release 9.8 on a mac 10.11. After I have installed the proper codecs based on the readme via brew install I try to build the example project and I get the following error.

dyld: Library not loaded: libavcodec.57.dylib
Referenced from: /Users/FakeMike/Desktop/of_v0.9.8_osx_release/addons/ofxHapPlayer/example/bin/example.app/Contents/MacOS/example
Reason: image not found
(lldb)

The limitation of the QuickTime 32bit library makes it not possible to compile the example on Ubuntu 17.10 (only has a 64bit release).
So I have to use the x64 version of OF 0.9.8.
First two errors of a long chain of errors I get:

../of_v0.9.8_linux64_release/addons/ofxHapPlayer/libs/HapSupport/src/HapSupport.h:41:2: error: #error Hap QuickTime support requires 32-bit QuickTime APIs but this target is 64-bit

I tried out the other branches but no success with those either, throwing the same errors.

Hi, I am trying to compile an example in Windows 10, Visual Studio 2015.
Made a new projec with Project generator and added the add on. Copied src and bin folders into my new Project. I am compiling first 32 bits
There were a lot of errors on the source cpp files. Has anybody tried to compile it in this platform?
Thanks!
D!

I would like to know what's the best chance to use the addon on Windows...

What about to use this other one: https://github.com/secondstory/ofxWMFVideoPlayer
Should be the best Windows alternative? or it's much slow...?

What I need is to play dual screen full hd, 3840x1080

Thanks a lot for this addon. I just wanted to throw in an issue I came across. I'm getting a "Quicktime.qts: write access violation" unhandled exception from time to time. There's no way for me to really reproduce it, but I was able to fix it by commenting out this line:

https://github.com/bangnoise/ofxHapPlayer/blob/master/src/ofxHapPlayer.cpp#L169

After that everything is running beautifully smooth, no memory leaks or whatsoever..

I've tried cleaning build folder and removing derived data, and neither works. Any suggestions?

OF v0.10.0
macOS 10.13.4
XCode 9.3.1

I am trying to use ofxHapPlayer to create one real time performance and I need to pass video frames without transparency to shaders for further postprocessing, but i have been unable to use the getTexture() method to work.

Most ofx functions that handle textures expect an ofTexture& instead of an *ofTexture as the function is returning, but even modifying the function to get an ofTexture& didn't work for me. I am not sure if it is for the texture color type or any other incompatibility.

I am assuming Raspbian is a valid distro for this addon, which could not be...
I could not install the libswresample-dev lib. Otherwise, it seemed OK.

When compiling, I got a bunch of errors regarding definitions:

Hello.

It's been a couple of years since I used this add-on, but remember really liking it. I'm trying it again. At compile time, I get the error 'QuickTime/QuickTime.h' file not found. I'm on Xcode 8.3.3 and macOS 10.12.

Any suggestions?

Thanks.

Hello,
I have successfully loaded a hapQ codec video. Unfortunately, I was implementing a fade as seen below on regular hap codec video which is not working with hapQ. Any ideas on this issue? Thanks for the help.

ofColor hapColor = ofColor(255);
hapAlpha.a = 50;
ofSetColor(hapAlpha);

I am developing on OSX El Capitan and OF0.8.4.
Trying to play videos with hap alpha codec one over other, I found that the one with opacity on top will become gray in color.
The gray color mainly appears on the pixels of opacity within 0 to 255, which is completely ok on 0 or 255 in alpha channel.
I can see that the gray part is transparent to show the bottom layer, but what I want is to blend it lighter in color than make it gray.
Anyone have idea how to adjust the code so that I can make it?
Thanks!

Does anybody know about a workaround to implement SetFrame and GetCurrentFrame functions in the libavformat branch? They appear to be commented in the code so....
Thanks guys,

Joan

Hello,
I tried making a vector of ofxHapPlayers just as below:

vector<ofxHapPlayer> player;  //note: this piece was in .h file

 ofDirectory videoDir;
    videoDir.listDir("movies");

    for (int i = 0; i < (int)videoDir.size(); i++){

        ofxHapPlayer tempVideo;
        tempVideo.setup(videoDir.getPath(i));
        cout << "Loading Movie: " << videoDir.getPath(i) << endl;

        player.push_back(tempVideo);
    }

When running this code I would get the following error in my console:

Loading Movie: movies/Organ_Intro_1.mov
*Loading Movie: movies/Organ_Intro_3.mov
*VidPlayerDebug(8972,0xa0ea11d4) malloc: ** error for object 0x6fda000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
*(lldb)

I made sure to log out that my paths were correct. I also tried a single ofxHapPlayer to load each video file which I did with total success. I then found a OF forum entry with the following code below. This code seems to work thus far. My understanding of what is happening is limited, but I thought it may be of interest to see what didn't work and what now works to see if there could be a fix in the addon, or if it's something I'm doing incorrectly on my end. Thanks for the help!

 vector<ofPtr<ofxHapPlayer> > player;  // this line of code was included in .h file

 ofDirectory videoDir;
    videoDir.listDir("movies");


    for (int i = 0; i < (int)videoDir.size(); i++){

        ofPtr<ofxHapPlayer> v (new ofxHapPlayer());
        v->loadMovie(videoDir.getPath(i));

        while(!v->isLoaded()) {

            ofSleepMillis(10);
            ofLog() << "sleeping" << endl;

        }

        player.push_back(v);
        player[i]->play();

    }

Hi,
Can you help me to find where can I download these libraries?

They are required at the HapSupport.h header.

Cheers,
Gustavo

While testing this addon, the default sample video worked fine, but when I tried these, I got crashes after around 5-20 seconds. Also, CPU usage went through the roof. I've attached a screenshot of the stack trace in debug mode if that's helpful. The videos I tested are here:
http://vidvox.net/download/SamplePackOneHap1080p.zip

Trying to use ofxHapPlayer with the most recent openFrameworks fro git I get the following error. Error: Field type 'ofxHapPlayer' is an abstract class. My guess is this is due to some changes in ofBaseVideoPlayer maybe a virtual method that is not implemented by ofxHapPlayer. I looked around and tried to make sure every virtual method ofBaseVideoPlayer had an implementation in ofxHapPlayer but did not manage to fix it.

Hello!
I am using the libav branch, OSX 10.12.
It compiles but crashes right after execution with this message:
dyld: Library not loaded: @rpath/snappy/lib/osx/libsnappy.1.dylib

Reason: Incompatible library version: Cannula_Munich64Debug requires version 5.0.0 or later, but libsnappy.1.dylib provides version 1.0.0

It is my understanding that the included snappy lib in the bundle is version 1. Is there anyway to update the version in the bundle?

Thanks!

While compiling in Code::Blocks I get:

I'm working for Igloovision on updating a Windows app from OF 8.4 to 9.7
We want to use ofxHapPlayer as the default player, but if the movie is non playable we try other players.

I've switched to the libavformat branch and have found that isLoaded() is no longer true immediately after calling load(), I'm guessing because the load happens in a new thread?

Can I find out somehow if the load is in progress and wait for a result?
Is there any other way of testing whether the movie can be played or not?

The video just renders as a black box when I play it at altered speed from a thread:

class MyThread : public ofThread {

    ofxHapPlayer* hapPlayer;
public:
    void assign(ofxHapPlayer* p){
        hapPlayer = p;
    }

    void threadedFunction() {
        hapPlayer->setSpeed(ofRandom(0.2, 4.5));
        hapPlayer->setPosition(0);
        hapPlayer->play();
    }
};

MyThread myThread;

void ofApp::setup(){
    hapPlayer.load("test/video.mov");
    hapPlayer.setLoopState(OF_LOOP_NONE);
    myThread.assign(&hapPlayer);
}

void ofApp::update(){
    hapPlayer.update();
}

void ofApp::draw(){
    hapPlayer.draw(5, 5);
}

void ofApp::keyReleased(int key){
    myThread.startThread(true, false);
}

Hi!
I would like to know how the addon manages the info of the clip and its frames once it is loaded in memory and how it is closed.
I am experimenting issues when loading several in an array, like some positions being smashed by other clips.
Thanks,
Diego

With OF 0.9, using QuickTime becomes a pain on Windows. We should use the DirectShow codec instead. Pull requests very welcome if anyone works on this.

hello there, just wanted to check that i'm not missing something here. i'm trying to have multiple players next to each other. but only one of them outputs sound.

also the app locks up, when i close it. debugger pointed me to
ofxHap::AudioThread::~AudioThread()

guess the audio streams are clashing somehow? is there a way for me to fix?

i'm on osx 10.13, openframeworks 0.10.1 and ofxHapPlayer master branch.

thank you in advance! love this addon <3

Hello,

I'm using the libavformat branch on MacOS Sierra. The compiled app works fine in the project folder but if I move this elsewhere it fails to start. The crash log seems to inidcate it cant find libsnappy.1.dylib ?
log.txt

ofSoundStream sucks (see openframeworks/openFrameworks#5519)

will require per-platform solution without using ofSoundStream - or use libavfilter to mix down to a single stream, which won't be a safe solution if users are also using ofSoundStream.

I have a strange issue.
My application plays some Hap Alpha files. Everything works fine on two different Windows computers (one has NVIDIA Titan card, the other has an integrated Intel Iris Plus 650). It even works on my Mac with a NVIDIA GT 750M card. But...

When I try the application on a machine with a AMD Radeon RX Vega – there is no image drawn. I have also tried it with another (identical) computer with no luck.

Then I tried to swap the files to normal Hap (no alpha) – and the video shows perfectly through the AMD graphics card. Strange.

So... something about Hap Alpha compressed textures seems to not be compatible with the AMD drivers. Has anyone had similar issues?

BTW. I'm on WIndows 10. Tried both 32-bit and 64-bit binaries. No difference.

My system setting is
ubuntu 16.05 LTS
openframeworks v0.9.8_linux64_release

I have ran linux instructions before hand.

Any ideas?

Thank you!

The work on this branch is very much appreciated. Everything basically works, expect when I tried using a vector to store instances of ofxHapPlayer. It makes sense since the copy constructor isn't implemented. Is there a better way to store dynamically created ofxHapPlayers?
If not then is this I guess a way of saying I would love to see this implemented :) (I would do it myself but I know it's very difficult to get it right with pointers and such).

Hi!
I am experimenting gltiches when loading into memory. First they happened because if calling .update right after calling .play, but now they seem to happen when loadin -.load- them in a pool/array.
Thanks!

Hi everyone,
I just tried ofxHapPlayer on Linux Ubuntu Studio. The example run without errors, but the video appears like in the attachment.
Is this an issue on my side or on the addon's?
Hap videos play well with mPlayer, b.t.w.

bests,
Gil

• Xcode: Base SDK - macOS 10.13 (master branch)

Works

• Project Generator > add ofxHapPlayer > load / update / draw (first video works)
• Add second ofxHapPlayer (different video) > load / update / draw (both videos work)

Doesn't work

• Change OpenGL to 3.2 (first video works, second renders black)

I'm going to look into this but posting here in case anyone has run into this and can help. Thanks!

(main.cpp)

ofGLWindowSettings settings;
settings.glVersionMajor = 3;
settings.glVersionMinor = 2;
ofCreateWindow(settings);

ofRunApp(new ofApp());

I have a project that is playing back some Hap files with audio. All is fine with the inbuilt sound card however, when I install the MOTU soundcard drivers (which install ASIO drivers), my app crashes when the videos are loaded. Even when the soundcard is not plugged in.

Is this a known issue with a solution?

sorry :/

I've just tried to load a recently encoded Hap Q Alpha from a tiff sequence (using quicktime 7)
Hap Q Alpha, 1920 × 1080, Millions+
and it returns the following error:

[ error ] ofxHapPlayer: Invalid data found when processing input (may not be a Hap movie)

Using libavformat here

AudioThread needs to fade audio out when stopping and jumping to avoid audible clicks
