I have an application that saves an .avi using the default mpeg4 encoder.
Since my application is GPL, I wanted to add H264 encoding. I compiled
libx264 and linked without any problem.
When I try to save with the h264 codec changing the code that works for
AV_CODEC_ID_MPEG4 (to AV_CODEC_ID_H264), all frames are parsed, however
only half of the frames are saved in the avi file. I wonder if this is
because h264 expects a two pass compression or some other setting is wrong.
I would appreciate it if someone could provide some code of saving in h264.
This is the output of h264 I get:
[save] Open encoder h264

I tried modifying muxing.c and that works without problems.
Any help or ideas are welcome.
