  • Revert "avfilter/src_movie : switch to activate"

    8 septembre 2020, par Nicolas George
    Revert "avfilter/src_movie : switch to activate"

    This reverts commit abc884bcc005c450a34e56cd1f4b8b6fa17ea768.
    

    This patch was pushed without actual review.
    
An actual review would have revealed that the switch to activate
    
was not done correctly because the logic between request_frame()
    
and frame_wanted is not as direct with filters with multiple
    
outputs than with a single output.

  • FFMpeg How to extract individual audio channels from wav/.w64 and insert in .mxf with track tags

    11 septembre 2018, par Vince

    Hi 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.
    All the best
