Hi:
I've followed the compile & setup instructions on
http://ubuntuforums.org/showthread.php?t=786095 to install ffmpeg/libavcodec
and external codecs to my system.
I modify/compiled some example codes on web and it works for all the internal
codecs. But when I try to decode an AC3 (libfaad) stream my
avcodec_find_decoder() function gave me a NULL, my print out shows:
Unsupported Audio codec! ID: 0x15003
The installed ffplay can decode the audio and can dump something like this:
Stream #0.0[0x1021]: Video: vc1, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9],
Stream #0.1[0x1025](eng): Audio: ac3, 48000 Hz, 5.1, s16, 640 kb/s
But my program can only dump:
Stream #0.0[0x1021]: Video: vc1, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9],
Stream #0.1[0x1025](eng): Audio: 0x0000, 48000 Hz, 5.1, s16, 640 kb/s
I don't know if there are any extra steps to enable external codecs in user
code other than av_register_all(), please help me with this, as I've searched
many docs and codes in ffmpeg project without a hint.
Regards,
John
