  • AVAssetWriter single frame

    5 novembre 2015, par Robert Figueira

    I’m trying to encode frame sequences to quicktime movies using AVAssetWriter, which works brilliantly. Problem is, it fails when I give it only one frame to write as a movie (the details of why I need single frame quicktime movies aren’t important, suffice to say it’s a necessary workflow thing for a very specific use case). It works fine with two frames, but with one frame it exits with the following error when calling AVAssetWriter.finishWritingWithCompletionHandler :

    writer failed with error : Optional(Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo=NSUnderlyingError=0x6180000427c0 Error Domain=NSOSStatusErrorDomain Code=-12769 "(null)", NSLocalizedFailureReason=An unknown error occurred (-12769), NSLocalizedDescription=The operation could not be completed)

    This is true for all file types - since by that time it’s just reading in pixel buffers. I stepped through line by line while debugging and it definitely has appended the single pixel buffer before finishing, it just won’t write the movie with only a single frame.

    The thing that makes me think it’s more of an Apple problem and not just me is that ffmpeg won’t write single frame movies either... Anyone have some insight as to why this is happening ? I can’t see any reason why a two frame movie would work fine but a one frame movie fails to write. Thanks,

  • FFmpeg watermark directory instead of single video

    5 décembre 2019, par Matt

    This code is working fine to watermark a single video at one time. What my question is, how would I modify this code to watermark and entire directory (*.mp4) instead of just a single video. Ideally after the watermark is done and output it would keep the same file name. To me this would be easier than having to have to do a single video at a time and just have ffmpeg do an entire directory. Thank you for your help.

    ffmpeg -i /Users/matth/OneDrive/Desktop/Raw_videos/video01.mp4 -i /Users/matth/OneDrive/Desktop/Raw_videos/watermark.png -filter_complex overlay=W-w-5:H-h-5 -codec:a copy -preset ultrafast -async 1 /Users/matth/OneDrive/Desktop/Upload/video01-watermarked.mp4

  • How to normalize a single audio file with ffmpeg [duplicate]

    1er avril 2021, par Max Smith

    I need to process a single audio file, so that its loudest peak becomes as loud as possible, while all the rest of the waveform amplifies accordingly.

    


    How can I do it with ffmpeg ?
