FFMpeg How to extract individual audio channels from wav/.w64 and insert in .mxf with track tags
11 septembre 2018, par VinceHi my problem is I have 2 .w64 files (extended wav format) each file has 16 mono channels of audio. I want to be able to extract specific channels of audio from each of those .w64 files and insert those channels into an .mxf file as separate single channel mono audio streams and to be additionally able to set the Tag information on those audio streams. I have tried using -map and so on but it seems to take all the channels from the .w64 files and insert a single audio stream of 16 channels. I apologise in advance as I’m very new to ffmpeg and thanks in advance for any advice any of you can offer. This is all specific to command line usage on windows.

Revision de6ecc5ac3 : Selective masking of split modes. Allow selective masking of individual split m
4 octobre 2013, par Paul WilkinsChanged Paths :
Modify /vp9/encoder/vp9_onyx_if.c

Selective masking of split modes.Allow selective masking of individual split modes rather than
just a single on / off flag.For speed 2 recovers the large speed loss seen for some derf
clips in change Ie6bdfa0a370148dd60bd800961077f7e97e67dd4
and a small quality gain.For speed 1 10 % speed increase observed locally on some derf clips
for minimal quality change.Change-Id : If86191087b93cbc05351c26c60c7933e2149e485
