Hello, everybody! I have a problem. When I keep my application running, after some hours of running it crashes and in log I see errors from h264 decoder. Can I get a better (more stable) h264-decoder from somewhere and force opencv to use it?
You can basically use every decoder by using the specified fourcc code. You can choose them from this list:
http://www.fourcc.org/codecs.php
Be sure to have the decoder installed on your system, and it will work without problem. However, when you say your application crashes after some time, I would consider looking into memory leaks. Possibly you are allocating memory somewhere and not manually deallocating it anymore, slurping up your memory bit by bit.
I think I haven't posed my question very clearly. I have h264 decoder installed. But, as I said, current decoder crashes after some time. It can be a memory leak, but memory looks fine in task manager. I think, it has to do with decoder implementation. As I said, if I get another h264 decoder, for example from Elecard or from Main-Concept, can I force OpenCV to use the new h264 decoder?
YESH, like I said, if the decoder is supported by the fourcc library, since you have to specify which decoder you want to use in the command for video writing :
CV_FOURCC('D','I','V','4'), in this case I have added the MPEG4 DIVX decoder because H264 gave problems on my windows machine also.
I am facing a similar issue. It seems that if you install a different set of codec then the machine will use the different set. This is my experience. The issue that I seem to have is that the different set is not always found and so my code will intermittently crap out on different formats (e.g., MP4).
I believe that using the fourcc function is for encoding and not decoding.
If you solved the problem would you share your solution.
Thank you,
Anthony
