• 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"

  


  This is the verbose output :

  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.

  


• "No Java virtual machine has been registered" error when using "mediacodec"

  12 septembre 2018, par Mohammed_BEY

  I successfully cross-compiled FFmpeg with "mediacodec" (developed in Java) library for aarch64 ARM architecture under Android OS.
  When I try to run FFmpeg on Android without "mediacodec", it works just fine.
  However, when I run it with "mediacodec" option I got an error :
  "No Java virtual machine has been registered"
  Here is the command line I used :
  ./ffmpeg -vcodec hevc_mediacodec -i jellyfish-20-mbps-hd-hevc.mkv -f null out.null

  1) is is the problem of JRE ?
  2) if so, could someone guide me to enable JRE on Android, or cross-compile it ?

  Actually, I tried many times to cross-compile "openjdk" for aarch64 but none works.

• FFmpeg command is very slow on Android even with "-preset", "ultrafast"

  7 janvier 2019, par 1234567

  FFmpeg command is very slow

  This is the FFmpeg command I am using

  {
  
   "-y","-i",j, "-filter_complex",
  
   "amovie="+audio+":loop=1000," +
  
  "asetpts=N/SR/TB,atrim=0:10,adelay=20000|20000,apad,volume=1.5[a1];" +
  
  "[0:a]volume=3.5[a2];" +
  
  " [a1][a2]amerge,pan=stereo|c0code>

  It has a simple 5 min and 30 sec long video
  and size is 32 mb, but it takes 9 min for ffmpeg to add audio to video.

  Even after I have added "-preset", "ultrafast" it’s really slow

  How Can I speed up the process.
