I am using the macports version of mencoder (though I have the same results when I build it myself), and I am getting an error when initializing the audio decoder when trying to transocde a video from the iphone (or a flip cam). I know it isn't simply a problem of the codec not existing in the build, as I can work with regular AAC streams without trouble. If I build ffmpeg against the exact same libfaad (I used --enable-faad-external when the internal version failed to work, but with the same results), it correctly decodes the audio of a file the mencoder cannot. I am hoping that there is some kind of command line parameter that I can pass through to libfaad from mencoder which will cause it to correctly detect the stream type and successfully initialize. If I use the following command: mencoder input.mov -o output.mov -of lavf -oac lavc -lavcopts acodec=libfaac -ovc x264 -x264encopts subq=5:8x8dct:frameref=2:bframes=3:b_pyramid:weight_b:bitrate=600000 It correctly transcodes the video, but it can't decode the audio. I get the following error messages Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding) FAAD: Failed to initialize the decoder! ADecoder init failed :( ADecoder init failed :( Cannot find codec for audio format 0x6134706D. If I explicitly specify the codec using -fafmttag 0x706D, the results are no different. If I add 0x6134706D as a format in the faad section of codecs.conf, I get the same result. I know that faad is capable of dealing with this audio, since ffmpeg does it just fine (but it has issues with the video - I can't win). I don't see anything in all of my searches which would suggest that there is some parameter I can specify which will get passed through to libfaad, but I suspect that is what I need. Also, -oac copy does not work, though that is actually what I would prefer, since by transcoding, I'll be moving HE-AAC to AAC, and I'd really far prefer to leave the HE-AAC intact. Any advise would be greatly appreciated. Basically, all I really want to do is increase compression and resize an iphone video (I left the size change filter out of the command above in order to simplify) --sam _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
