[FFmpeg-user] ffmpeg -layer flag
Hello, I'm trying to find info on the -layer flag for ffmpeg which seems to be undocumented in terms of examples. I have a sequence of multilayer EXRs that I'm trying to convert to JPEG and from the sounds of it, I would be able to extract channels in the multilayer EXR [e.g. R,G,B or Diffuse, etc] and outtput the JPEGS that way due to ffmpeg not being able to straight up convert from mutilayer EXR -> JPEG. I've scoured the web, can't find anything in terms of examples on how to use this flag. https://gist.github.com/tayvano/6e2d456a9897f55025e25035478a3a50#file-gistfile1-txt-L598 EXR AVOptions: -layer .D.V…. Set the decoding layer (default “”) Thanks, Dan ___ 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".
