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

    20 décembre 2016, 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

  • ffmpeg concatenate videos - what metadata needs to match [duplicate]

    13 juillet 2022, par yarrichar

    I am trying to concatenate videos that can come from a variety of sources.

    


    I was just using the -f concat option, but this runs into issues when the formats don't watch.

    


    I can use the filter_complex option (as described in the wiki - https://trac.ffmpeg.org/wiki/Concatenate) but this is much slower.

    


    What metadata (codec, bitrate, fps, etc) needs to match so that I can use the faster -f concat option to join the videos ? My understanding here is not great atm.
