Dropdown menus remain empty

Hi, when I want to use Captura 7.01 (Windows 10), all dropdown menus stay empty - no matter if I use the setup or the portable version. (Please see screenshot.) Strangely, I had used the portable version before, and then it had worked. But after deleting the portable version and installing the setup version, I cannot use either version any longer. Kind regards, Mat

FFMpeg exited suddenly while recording

Hi,

Thank you for this great project. I am using Screna in one of my projects. I use RegionProvider, MixedAudioProvider and FFMpegWriter. While recording the FFMpeg exited suddenly without me calling pause or stop method. Though it happened only once I am little bit skeptical on whether this might happen again. What do you think might be the reason for this ?

Recording both Microphone Input and Speaker Output

now i want record both side audio in/out.
but now this project cant record both.
i hope u help me.

RectangleConverter.ConvertFromString Culture

When I run "captura shot --source 100,100,300,400" the program stops with exception:

Unhandled Exception: System.Exception: 100,100,300,400 is not a valid value for Int32. ---> System.FormatException: Input string was not in a correct format.

   at CommandLine.Parser.ParseArguments(String[] args, Object options, Action`2 onVerbCommand)
   at Captura.Console.Program.Main(String[] args)

This is caused by culture of my OS, wich is different from en-us. Line 122 MainViewModel.cs:
var rect = (Rectangle)RectangleConverter.ConvertFromString(Settings.Instance.LastSourceName);

But I'cant provide corect input because of the limitation "^\d+,\d+,\d+,\d+$" in Program.cs:

            if (Regex.IsMatch(CommonOptions.Source, @"^\d+,\d+,\d+,\d+$"))
            {
                var rect = (Rectangle)MainViewModel.RectangleConverter.ConvertFromString(CommonOptions.Source);

                FakeRegionProvider.Instance.SelectedRegion = rect;
                video.SelectedVideoSourceKind = VideoSourceKind.Region;
            }

It would be nice to make RectangleConverter.ConvertFromString(CommonOptions.Source) culture invariant.

Let the user make mouse click circle smaller and more transparent

When I enable mouse click monitoring a fat yellow circle is drawn around the mouse click.

I found no option

• to change the color
• make it partially transparent (e.g.30%)
• define a smaller size of the circle (e.g. only 20 pixels)

Could you add these options

Cannot record mp4 with multiple screens and width not dividable by 2

Hello
Thanks for your project, I took some inspiration for my own recorder :)
While working on that I found out that ffmpeg/mp4 fails when the screen resolution is not dividable by 2. This can happen if you have multiple screens where one is lower than the other.
To fix this, I use scaling for the videou out like this:
-vf "scale={img.Width}:-2"
With that line, it uses the regular width (which is usually dividable by 2) and makes the height dividable by 2 but keeping the aspect ratio. Maybe there should be some more calculation in case that the width is also not dividable by 2.

Remember last used Codec and Video Window/Screen

Would it be possible to also save the last used video codec and window so I don't have to set them again after every restart?

Where a settings stored? Export+reimport on another computer

Where are the settings pf Captura stored?

I prefer a storage into an *.ini file in the installation folder. This way I could keep all related files together and run Capture from USB flash drive.

Furthermore I could copy this *.ini file onto another computer into another Capture installation

Could you let users at least export (+import) settings

Is it possible to use Captura's DLLs for making screenshots into shared memory

It needs to make screenshots and execute them.
One sulution is to make screenshot into shared memory, and execute it in a target application.
Is there an Captura's API which can do a part of this.

Issue about recording with audio

Hello, developer. Here I got an issue when I was recording with audio. It seems that it cannot create any video file while recording, and when the record stops, I get only an MP4 file with a frame of screenshot.

Would you please solve this issue?

console ffmpeg capture file has size 0

I used "captura start" and then used "q" to quit the recording after about 10secs. It says a video file was saved. But it has size 0. I tried setting a filename in another directory. All other params where omiited so default. ffmpeg is available in path. The ui captura works fine.

Let users select installation folder + offer a portable version

As I found out the user has no choice where to install Capture.

He is forced to install it into

C:\Users<username>\AppData\Local\Captura\

Why not letting the user select a different folder e.g.

D:\tools\screenrec\Captura
?
Furthermore I would appreciate if you could offer another separate portable package of Capture
which needs only to be extracted to run.

Thanks

Video plays back too fast after capture.

See this video for sample (it was around 10 seconds long when I took it):
https://youtu.be/PtNPoYsXy-0

Edit: It only does this if the frame rate of the video exceeds 30fps.

Region Selector will not size itself to 1024x768 pixel windows

Hello,

The Region Selector will not size itself to an object with 1024x768 pixels. To illustrate this, I created a program that simulates a Virtual Machine Guest window (what I use Captura for). The Region Selector works great with sizes of 800x600, 1280x720, and so on. But it will not conform to 1024x768 resolution.

Watch video for a demonstration of this bug.

Viruses in Portable Version?

Hi,

I've just downloaded the latest portable version and scanned the files using VirusTotal which found the following issues:

Comodo | Heur.Packed.Unknown | 20171125
Cylance | Unsafe | 20171125
Cyren | W32/GenBl.3EAA0B13!Olympus | 20171125
TrendMicro-HouseCall | Suspicious_GEN.F47V1117 | 20171125

Captura looks great and I would love to install it but having just cleaned my system yesterday from a troublesome infection I am double checking everything prior to installing it.

I have attached the file so you can have a look at it.

Captura-Portable.zip

Hope this helps

Screen Cast fails on UAC

when ffmpeg exit can reconnect?

Error FFMpeg + HEVC

Multiple screens bug

When i try to capture DISPLAY1 only it captures DISPLAY1 and a black screen at the position of DISPLAY2, so the result is, on the left of the screen, my video and on the right, a black square.

Screen recording crashes after +15min running

When using screen recording to MP4 (x264 | AAC) recording stops after 15-20min. running.
No webcam or audio, just screen #1 with default options. Tested on v6.0 under W10.

PS.
Beautiful code. Congratulations.

Problems while capturing Gifs

• Quality is not implemented.
• High memory usage on high frame rates (Workaround: Use Variable Frame Rate option).
• (RESOLVED) Gif does not support delays less than 10ms, so causes problem with Desktop Duplication.

FFMpeg | Gif

• Color Blending error. See #76 (comment)

Gif | Gif

• Huge File Size
• (RESOLVED): VFR delays are set after the frame not before it.
• (RESOLVED): If recording is paused, VFR Gif Recorder adds that delay into the recording.

Webcam Capture not working

Webcam Capture is not working for me. Windows 10 64-Bit 1703. Chose "Integrated Camera" but preview windows remains black whereas a recording will show white noise. Other programs such as OneNote can use the webcam.

This is a built-in device on my Lenovo T540p.
Device managers says it's a "SunplusIT Integrated Camera".

Device Path:
USB\VID_5986&PID_026A&MI_00\6&7AE9AEF&0&0000

Hardware-IDs:
USB\VID_5986&PID_026A&REV_0003&MI_00
USB\VID_5986&PID_026A&MI_00_

Running Captura as Administrator makes no difference. Enabling Desktop Duplication API makes no difference.

How can I help debugging?

Captura.Console ProcessExit

When I run console app like "captura start" and then just close console window the output video file is broken.

It would be nice to stop video recording when user terminate process, like this:

AppDomain.CurrentDomain.ProcessExit +=
    new EventHandler(CurrentDomain_ProcessExit);

Specific window capture

Your work is very good. Thank you. But do not try to capture a specific window. When minimized, the window shrinks or open a new window on the full screen is still recording. When you will be able to fix this problem? Also How to add system sound except for the microphone sound ?

Create installer package

It would be nice if there was an installer packages, that would create shortcuts in start menu and desktop, put files in appropriate places, detect ffmpeg binaries, and so on.

Captura gets stuck in less CPU systems

Hi. Is there any minimum system requirement for using Captura ? I tried it in a 1.4 GHz Duo Core, 4GB RAM system. The system gets stuck everytime I do that. Also is there a way to make it run in this configuration ?

[Suggestion] Adding webm option to video encoding

Since Captura has FFMpeg support already would it be possible to add webm (VP8) exporting?
While one could use another software to convert mp4 files made in Captura to webm it would be easier if one didn't have to do an extra step like that, all modern browsers support direct webm playback.
I still use WebMCam by thetarkus since Captura doesn't have the option, which I wish it did because besides this I'm very much liking Captura overall, though I'm not sure why the frame rate is limited to 30.

Video capture with audio does not work.

I think I just found a bug. If I select a microphone or speaker audio source, no video file is generated. Without any audio source capturing works. Can you please take a look at this?

Capturing Maximized RegionSelector

When RegionSelector is Maximized, the area captured is the same as that when it was in Normal state

Recordings in gif are huge

Hello i noticed strange thing
when i record 12 sec gif with settings like in this picture
the output file is about 40mb

Unable to resize Captura Region Area

Hi, I am using Windows 10 and unable to resize the region capture size. And it also randomly move by itself sometimes.

Inno Setup

Why not create a custom installer with inno setup?
With the languages ​​already found in the Captura and also please add my language that you send.
It would be good.

Error notification after continuous recording

In the end of MainViewModel.cs, use savingRecentItem instead of _currentFileName ?

FFmpeg 404s on Windows

Hi there, thanks for the awesome software!

I've just installed v7 & I couldn't download ffmpeg through the UI. It used to work on v6.
Anything I can do to help?

Add hotkeys to toggle mouse and keyboard overlay while recording

Add options to toggle mouse and keyboard overlay while recording. Specially keyboard toggle would be useful to trace special keys which can't be screen (like shortcuts in applications).

Lagarith codec and region selector suggestion

Excellent video capture program! I use it to make tutorials/info videos using virtual machines. Being able to record the VM guest from the host is important to me. Thank you.

I have a couple of suggestions:

• Query the locally installed codecs and allow their use. (I need Lagarith support for example).
• I use the "Region" option to record things. When the recording starts, it would be beneficial to hide the region selector during this time.

How can I donate to you? Your PayPal link does not work. I would like to use PayPal or CC card.

[Suggestion] Adding text overlays

Sometimes i want to add to captured video
some title or info about recording

it would be great if i could set some text overlays in config
and then use them in video

best with options like for keystrokes - font border background
great if i could create few text overlays and just enable disable them
even greater if i could use some defined variables like %date%, %time%, %dayname%

as always this is just a suggestion:)

Screen capture / Video Capture only black

Downloaded the compiled app first and it ran great. I downloaded the code and ran in Visual Studio 2017 and the screen capture and video captures are all black with no images. Any ideas what the issue might be?

Captura doesn't recognize DPI scaling

I have 1080p screen, and in my case windows 10 automatically changes DPI to 125%, so when you try to record a region with Captura it offsets the recording area by 25%.

Since Windows 10 changes DPI automatically for screens larger than 1080p, it will affect a lot of users.

ServiceProvider.MessageProvider.ShowError errors out when trying to run with default hotkeys occupied

If Captura encounters a global hotkey that it wants to use, it tries to show a human-readable error message on startup and carry on - but this is bugged and crashes the application altogether.

Steps to reproduce:

1. Globally occupy a hotkey that Captura uses in config (in my case it was Print Screen taken by OneDrive)
2. Run Captura

Runs without further issues after commenting out the following line:

Captura/src/Captura.Core/Models/Hotkeys/HotKeyManager.cs

When I run Captura.Console app from my GUI app like this:

ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.UseShellExecute = false;
startInfo.RedirectStandardInput = true;
startInfo.FileName = captureExePath;//captura.exe
startInfo.Arguments = "start --source 100,100,300,400";
process = new Process();
process.StartInfo = startInfo;
process.Start();

I get an exption:
"Cannot read keys when either application does not have a console or when console input has been redirected from a file. Try Console.Read."

   at System.Console.ReadKey(Boolean intercept)
   at Captura.Console.Program.Start(MainViewModel ViewModel, StartCmdOptions StartOptions)
   at Captura.Console.Program.<>c.<Main>b__0_0(String verb, Object options)
   at CommandLine.Parser.ParseArguments(String[] args, Object options, Action`2 onVerbCommand)
   at Captura.Console.Program.Main(String[] args)

This is caused by line 385 Program.cs:

while (ReadKey(true).KeyChar != 'q') ;

It would be nice to change this block of code for something more "external friendly" :)

...
else
            {
                var text = "Press q to quit";

                Write(text);

                while (ReadKey(true).KeyChar != 'q') ;

                Write(new string('\b', text.Length));
            } 
...

Exception on "Snap to Window"

If I select "Region" and then click on "Snap to Window" (press and release immediately) in Region Selector, I get an Exception.

Example is attached.

hi. most top

hi want captura when runnig, most top

but not show in video

can i ?

Option to show time elapsed

It would great to have an option
to add overlay with time elapsed
something like in Licecap

maybe even with some configuration
like time elapsed/time till end/total time

it would be useful in gif recordings

Command line cannot save video

Using V6.0 version, through command line captura start --length 10 --cursor --keys --speaker=0, the countdown ends the command line tool to stop, no video output. The start and end buttons in UI can be recorded and saved, and the win10 I use

[Suggestion] Twitch / YouTube Live / LiveStream / etc support

This app is SO much easier to use than OBS for recording from the screen.

Is there any way you'd consider adding Twitch / YouTube Live / LiveStream / etc support for real time streaming?
