  • Why A .FLAC File Converted by FFMPEG Cause File Explorer Unresponse on Windows 10 [closed]

    20 juillet 2022, par Alex King

    My File Explorer Always showing "Working on it."
I've tried many resolutions.
First,I disconnect my NAS drive. seems fine.
I test many times on diffirient windows 10/11 versions.
I thought it was SMB problem on windows. But i was wrong.

    


    Today I'm using FFMPEG convert .wav to .flac.

    


    .\ffmpeg.exe -i $Source -c:a flac $Dest 


    


    Just simple like this. Blow my computer up.

    


    Even worse, explorer.exe crash after I'm trying to open FF output folder.

    


    It's not the poblem from "Quick access" or "Search Index".

    


    I'm now 100% percent confirm the flac files that ffmpeg made will cause file explorer crash.

    


    I can't solve it without knowing the reason.

    


    Might related to audio file tag vorbis ?

    


    This is my FFMPEG info

  • PyAV/ffmpeg : How to resolve 'Reinit context to WxH ... deprecated pixel format'

    26 mai 2023, par hi im Bacon

    I am using the pyav library to read and process video data and as I am reading through the videos I am getting lots (and lots) of the following output.

    


    I am creating the videos by segmenting either a much larger source file or RTSP/HTTP IP camera.

    


    I would love to understand what this output actually means, and what I can do to prevent its output

    


    ffmpeg creating videos :

    


    ffmpeg -y -i https://manifest.googlevideo.com/api/... -pix_fmt yuvj422p -c:v libx264 -an -vf scale='min(1280,iw)':'min(720,ih)':force_original_aspect_ratio=decrease -r 12 -vsync cfr -x264opts keyint=12:min-keyint=12 -f segment -segment_format matroska -segment_time 5 -initial_offset 1656497474.686672 -strftime 1 /tmp/tmp87cc1n2o/%Y-%m-%dT%H%M%S.mkv -loglevel error


    


    python :

    


    container = av.open(io.BytesIO(...))
for frame in container.decode(video=0):

  • avformat/mov : discard data streams with all zero sample_delta

    6 juillet 2022, par Zhao Zhili
    avformat/mov : discard data streams with all zero sample_delta

    Streams with all zero sample_delta in 'stts' have all zero dts.
    
They have higher chance be chose by mov_find_next_sample(), which
    
leads to seek again and again.
    

    For example, GoPro created a 'GoPro SOS' stream :
    
  Stream #0:4[0x5](eng) : Data : none (fdsc / 0x63736466), 13 kb/s (default)
    
    Metadata :
    
      creation_time : 2022-06-21T08:49:19.000000Z
    
      handler_name : GoPro SOS
    

    With 'ffprobe -show_frames http://example.com/gopro.mp4', ffprobe
    
blocks until all samples in 'GoPro SOS' stream are consumed first.
