Memory Leak in AForge.Video.FFMPEG.VideoFileWriter's Open Close Method. #319

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1.Create VideoFileWriter instance
2.Open video file
3.Close video file
4.Dispose the instance
Do this in for loop to create 100 instances.

What is the expected output? What do you see instead?
Memory should not increase. It should release memory as its disposed.

What version of the product are you using?
2.2.4

Please provide any additional information below.
This leads to memory leak in application.

Maybe. So what now?

Maybe you face the problem and try to solve it!

We have made the same experience with version 2.2.4. Unmanaged memory is 
growing steadily when you create a VideoFileWriter, open it, close it and 
dispose it afterwards.

What are you trying to say with this? Like to give a push - do it finally?

Exactly ;-)

Because your first response didn't sound as you would try to handle the problem.

If I can help you, please let me know how.

Greetings, Manuel

OK, I may need to remind you one thing ... I am not obliged to anyone to do 
anything. If I have time - I do it. If not, then not. The project is open, so 
you are welcome to go through the code. So the way you push will not help in 
any way.

>> If I can help you, please let me know how.
Yes, you can. Fix the problem and send the patch to the benefit of others.

I'm looking into this, as it's blocking some efforts with HD video. If anyone 
has any hints I'm more than happy to receive them, otherwise I will post any 
updates if/when they come.

Has anyone found a fix for this?

Pretty sure the bug is in ffmpeg itself as the memory leak only occurs on 
certain streams (mainly RTSP streams)

Fixed. See issue #406.

Using avformat_free_context() instead of av_free() to properly free FFmpeg's 
format context.
