Re: [FFmpeg-user] Does FFMpeg support the new IMF format?
Good morning/evening, Quick note that I have been working with Valentin Noel and Marc-Antoine Arnaud on adding IMF as an input format to FFMPEG: https://github.com/sandflow/ffmpeg-imf In particular, the objective is to support (a) demuxing of image and audio virtual tracks (including multichannel audio routing) and (b) supplemental packages. Below is sample usage: ffmpeg -assetmaps ASSETMAP.xml -i CPL_da656e28-ae37-4734-8b8f-c5b2aa187783.xml out.mp4 Other details at: https://github.com/sandflow/ffmpeg-imf/blob/develop/README-IMF.md We plan to submit a patchset in the coming weeks, unless unforeseen gremlins pop-up. Feedback/comments are welcome, as always. Best, -- Pierre ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
