• how to remux/fix video file saved with testdisk that reports error "Invalid NAL unit size"

  18 août 2022, par Luka

  I have deleted a video file from an SD card and then 'undeleted' it with tool called testdisk for Linux. It saved complete file (6Gb), but video seems broken (can't be played by any video players) and ffprobe reports :

  I'm no programmer, but have used ffmpeg a lot. How can I remux (or even re-encode) such file to fix this and make the file usable for further work ?

  


  I have created a 10seconds snippet with ffmpeg -i MVI_1399.MP4 -t 00:00:10 -c copy MVI_1399_10sec.mp4 for anyone to check. I also created a ten second snippet from a functioning clip from the same camera (I presume same codec parameters etc) :

• A ffplay Error :"Failed to set value 'yuv420p' for option 'pix_fmt' : Option not found"

  3 novembre 2023, par DavisTao

  I was trying to play a video by ffplay. Here’s my command :

  


  ffplay -f rawvideo -pix_fmt yuv420p -video_size 640x360 Resources/video.h264

  


  but I got this error :
Failed to set value 'yuv420p’ for option 'pix_fmt: Option not found

  


  So l used another command to make the video playing correctly, and this is the command :

  


  ffplay -f rawvideo -video_size 640x360 Resources/video.h264

  


  I wonder why the first command reported the error, because I used ffplav -pix_fmts and found that yuv420p is supported.

  


  By the way the pixel format of the video file is yuv420p exactly.

  


• Ffmpeg x265 error : "Color Primaries must be", "ransfer Characteristics must be", "Matrix Coefficients must be" [closed]

  16 septembre 2022, par Mister Sir

  I'm trying to do the following conversion :

  


  ffmpeg -i video.mp4 -map 0 -c copy -c:v libx265 -crf 30 -vf "scale=-1:\'min(720,ih)\'" -c:a libopus -b:a 44k -map_metadata 0 -loglevel error -hide_banner video.mkv


  


  This works fine except for a specific video. I'm getting the following output :

  Can't find a single result when I google the first error text, ffmpeg "Color Primaries must be unknown"

  I'm not an expert at video encoding, so I don't really know what this all means. Probably something with the source file. How to get around this ? Thanks in advance ! If I need to upload the video, let me know how I can do that.
