FreeBSD 7.0 release amd64 I compiled ffmpeg from ports. Input is mpeg2 transport stream from OTA ATSC/8VSB. Output is DV. My old non-ports ffmpeg reports the input as Stream #0.2[0x34]: Audio: ac3, 48000 Hz, stereo, 384 kb/s or Stream #0.2[0x34]: Audio: ac3, 48000 Hz, 5:1, 448 kb/s or similar. Ffmpeg from ports says: Stream #0.1[0x44], 1/90000: Audio: liba52, 48000 Hz, stereo, 192 kb/s output is: old: Stream #0.1: Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s new: Stream #0.1, 1/90000: Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s Audio was ok with the old version. I don't recall haviing to jump through any hoops to get audio working before. Problem is, with the new ports version, the output is silent. No error messages, just silence. Adding "-acodec ac3" gives "unknown codec". There is a libavcodec/ac3dec.c ac3 decoder, but it doesn't appear to be used. Turning on ENABLE_AC3_DECODER in config.h doesn't build. Didn't find anything with google. What is the secret?
