Lagarith codec and region selector suggestion about captura

[MathewSachin]

Option to hide region selector during recording has been implemented.

It will be available in next release.

• I'll add the region selector hiding feature ASAP.
• As for the locally installed codecs, I think I need to investigate.

Oh, And thank you for your generosity, I've fixed the PayPal link

As for the locally installed codecs, I think I need to investigate.

Yeah, hopefully not too hard. This topic might help as far as enumerating codecs. Don't know what you'll need to do ... to actually use the found codecs.

Implemented Lagarith codec support for Avi files.

Here are the steps to test it:

1. Install Lagarith codec from here
2. Download Captura Test Build
3. Extract Zip and run Captura.UI.exe.
4. For video encoder, select SharpAvi then Lagarith.
5. Start Recording

Hello,
Strange crash on my main system. When I test under a VM, it works very well. See video. Let me know how I can help you debug the issue.

Thank you.

[MathewSachin]

I'm not sure about the error maybe updating the graphic card drive might help.
I'll further investigate.

Looks like a clue here. However, I can get Captura to work when I log in as Administrator. So, what do you think of that?

[pcunite]

Update:
I found the issue. When I set RGBA (as shown here) then Mpeg4VideoEncoderVcm will cause an exception.

The reason it worked as Admin was because that was a different user profile and I had not changed the Lagarith defaults.

[MathewSachin]

That must be the problem since Captura uses RGB for all purposes.
So, it requires the encoders to expect the same as input.

[pcunite]

Okay, I'll test and see if I truly need RGBA (which means RGB32 with active alpha, I think)

Another issue: Captura will not record a playable AVI if Lagarith option Enable Null Frames is set.

Enable Null Frames:
When a frame is identical to the preceding frame, it can be replaced with a nullframe. This indicates that the program reading the video should simply reuse the previous frame. Nullframes can increase compression and speed, but there may be a few editing programs that do no handle them well; disable nullframes if you notice the wrong frame being displayed during still sections of a video.

[pcunite]

Testing is going good. I can say that working with the Lagarith codec appears to works well. I don't seem to have a need for Enable Null Frames or RGBA at this time. Doesn't seem to change the look of my output - probably because I'm just recording VMware Workstation guests. There is a new issue with this. I'll make a new thread.

[pcunite]

I think you can mark this thread as solved. My suggestion would be to read this registry key and verify the settings as shown. If not correct, show a dialog box asking the user to change them (or do it for them ~smile)

HKEY_CURRENT_USER\Software\Lagarith:

• Mode = RGB
• NullFrames= 2294784

[MathewSachin]

I'm not planning of accessing the registry.

I think adding the information to document will be sufficient.
