I already had it in mind to send a patch, but there is still an unknown
issue for me according the "time_base" property for the audio codec.
For PSP among other things you have to set for the audio codec:
c->time_base.den = c->sample_rate;
c->time_bas.num = 1;
in the add_audio_stream method. But it does NOT work when you want to create
an avi file. When you call "output_example test.avi" it complains:
"error, non monotone timestamps", "Error while writing audio frame"
You can simply test it, when you add these two code lines into the
"add_audio_stream" method in output_example.c. I had a look into ffmpeg's
audio coding settings and it does set time_base.den to sample_rate.
I already wrote this in the user news group. When I solved this problem I
will send a patch.
