The problems with m4a files are caused because the shaved chimps at Sansa can't design a decoder. Their literature quotes "AAC (Apple iTunes AAC-LC (.M4A) Audio)". And the FFmpeg files show... Format profile : Apple audio with iTunes info Codec ID : M4A Format profile : LC With previous models it was possible to use RockBox as a workaround. As demonstrated in the trac report, many other encoders/muxers produce files that play OK with the Sansa. Seems that avformat is doing something different. Trying to make perfect files to use with perfect decoders. Those other old encoders/muxers probably make cheap and cheerful files to use with a wide range of decoders. ''' does adding "-skip_iods 0" as an output option make a difference? Nope. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
