• React-Native FFmpeg-kit VideoCompress command not working

  6 septembre 2024, par Brian

  I'm Using FFmpeg-kit's React-Native Kit

  


  And I want to encode H264 to HEVC.
But the Videotoolbox in ios not working

  


  I use "ffmpeg-kit-react-native" : "^6.0.2"
And here is my Code

  


          // hevc_videotoolbox
        await FFmpegKit.execute(`-i ${videoUri} -c:v hevc_videotoolbox  -c:a aac -tag:v hvc1 -movflags +faststart -y ${outputUri}`);
      } else {
        await FFmpegKit.execute(`-i ${videoUri} -c:v hevc_omx -c:a aac -tag:v hvc1 -movflags +faststart -y ${outputUri}`);
      }


  


  But I got the error follwed like this

  How can I fix this error ?

  


  I read the
stack overflow

  


  

  1. Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height
