FFmpeg - Take 128 Channel WAV and Transcode to MKV with 128 Discrete Mono Tracks [closed]
17 août 2023, par Matt CohenI have a use case where I need to take individual WAV files with 128 channels in each one and output corresponding MKVs with each source channel as its own discrete mono track.


I've been playing around with the channelsplit and channelmap functions but am having a hard time finding parameters that work with this many channels / this specific use case.


Is this even possible with FFmpeg ?


So far I've mostly been trying different variations of :


ffmpeg -i in.wav -filter_complex channelsplit out.mkv


Any help would be greatly appreciated.

FFmpeg encode video on the fly from images
13 septembre 2017, par user1658593I have an experiment setup (LabVIEW based) which produces png images at 40fps each with timestamp filename. The number of images is substantial (several thousands) and each of 6MB.
I was wondering if I could use ffmpeg to create a lossless video on-the fly from those images (instead of saving individual frames as image files).Unfortunately I do not know how to set up input parameter to ffmpeg in my case.
I have full control over image saving process, so I can substitute _save_to_png_ function with a dll call, or command line call.
Could you come up with some suggestions ?
