Thanks ! Yes, API seems to be not very easy.
I compiled output_example.c, for mpeg1/2 it works fine, but when I try to do
something like this:
./output_example test.flv
I get error:
Output #0, flv, to 'test.flv':
Stream #0.0: Video: flv, yuv420p, 352x288, q=2-31, 400 kb/s, 25.00
tb(c)
Stream #0.1: Audio: libmp3lame, 44100 Hz, stereo, s16, 64 kb/s
Assertion failed: (size), function flv_write_packet, file
libavformat/flvenc.c, line 338.
Abort trap
What am I doing wrong ?
