I have some aiff files in my music production library that I'd like to convert to flac. However they aren't recognized by ffmpeg:
$ ffmpeg -i Raylon-190-Full.aif ... [aiff @ 0x7fc3ce800000] unknown or unsupported codec tag: able is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented. [aiff @ 0x7fc3ce800000] If you want to help, upload a sample of this file to ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing list. (ffmpeg-devel@ffmpeg.org) [aiff @ 0x7fc3ce800000] could not find COMM tag or invalid block_align value Raylon-190-Full.aif: Operation not permitted These files can only be decoded by Ableton Live. Quicktime, VLC, MPlayer, and ffmpeg can't read them. I believe the 'able' tag is Ableton's proprietary format. I know it's 24 bit but no more. I exported one through Ableton to a 44.1khz 24 bit wav and the filesize comes out exactly the same so I know the format is not compressed. Also the exported wav matches the waveform precisely since if I add it back with inverted phase I hear nothing. Here is a sample file, in aif format and wav format: https://files-adamj-eu.s3.amazonaws.com/ffmpeg-devel/Raylon-190-Full.aif https://files-adamj-eu.s3.amazonaws.com/ffmpeg-devel/Raylon-190-Full.wav (I tried uploading to the ftp server as per debug message but couldn't connect.) Thanks for any help reverse engineering this format! -- Adam _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
