• Burning subtitles into video using ffmpeg overlay on react native

  25 avril 2023, par Youssef

  I have managed to complete this task on node server but it's too slow I don't want to upgrade my instance so I decided to do the conversion on the front end, my app is on react native can please somebody help me convert the code and keep the same args and options

  


  Server code

  


  // Execute the ffmpeg command to burn the subtitles into the video
const ffmpeg = spawn("ffmpeg", [
  "-i",
  "pipe:0",
  "-vf",
  `subtitles=${subtitlePath}:force_style='Alignment=10,OutlineColour=&H100000000,BorderStyle=3,Outline=1,Shadow=0,Fontsize=10'`,
  "-c:a",
  "copy",
  "-progress", "pipe:1",
  outputPath,
]);

// Pipe the videoResponse array buffer to FFmpeg
ffmpeg.stdin.write(videoResponse.data);
ffmpeg.stdin.end();

// Send the output file as a response once the process is complete
ffmpeg.on("close", () => {
  fs.readFile(outputPath, (err, data) => {
    if (err) {
      console.error(err);
    } else {
      console.log(outputPath)
    }
  });
});


  


  My try on react native but failed for several issues including, main ones are :

  


  


  No such filter : 'subtitles' Failed to inject frame into filter

  


  


  


  Invalid argument

  


  


  


  Error initializing complex filters.

  


  


  This is what I come up with so far

  


    componentDidMount() {
    FFmpegKit.executeAsync(`-i ${inputFilePath} -i ${subtitleFilePath} -filter_complex "[0:v][1:s]overlay=10:main_h-overlay_h-10" -c:a copy ${outputFilePath}`)
    .then((session) => {
      FFmpegKit.cancel();
  
      const returnCode = session.getReturnCode();
  
      if (ReturnCode.isSuccess(returnCode)) {
        console.log('Video with subtitles was created successfully!');
      } else {
        console.log('Error creating video with subtitles');
      }
    })
    .catch((error) => {
      console.log('Error creating video with subtitles', error);
    });
  }

• FFmpeg unable to save file on Android : Output file #0 does not contain any stream

  16 mai 2022, par John M.

  I'm having difficulty when saving a RTSP stream into internal storage using ffmpeg-kit -i rtsp://192.168.100.60:554/stream1 -c:v copy -c:a copy -t 5 /data/user/0/com.arthenica.ffmpegkit.test/files/test.mp4. The command is called using FFmpegKit.executeAsync(command, ...). There're issues with the circular_buffer_size option, but I read that the warnings could be ignored. The command runs fine on desktop using ffmpeg. Please find below the log.

  


  Any advice would be appreciated.

• ffmpeg : cannot copy data stream

  31 mars 2023, par darkshine — mp4, h.264, h.265, ffmpeg

  I've got the mp4 video file captured by DJI drone. The file contains the video stream and two data streams of unknown format. I would like to convert the video from h.264 to h.265 and also save the both data streams. Unfortunately, I cannot force ffmpeg to copy the data streams from input to the output.

  


  Here is the mp4 file :

  


  ffprobe DJI_0019.MP4

Unsupported codec with id 0 for input stream 1

  I tried the command below :

  


  ffmpeg -i DJI_0019.MP4 -map 0 -c:v libx265 -crf 25 -c:d copy -copy_unknown DJI_0019.v2.MP4

  


  The command fails with the following error. The output file is empty.

  


  [mp4 @ 0x556d0180ced0] Could not find tag for codec none in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:0 --


  


  Note that for "-c:d" option I tried different suggested values, none of them succeeded :

  


  copy
none
bin
bin_data
data
null
file


  


  In the meantime an attempt to save the data streams to separate files succeeds for the both of them with the commands :

  


  ffmpeg -i DJI_0019.MP4 -map 0:d:0 -c copy -copy_unknown -f data DJI_0019.data0.bin

  


  ffmpeg -i DJI_0019.MP4 -map 0:d:1 -c copy -copy_unknown -f data DJI_0019.data1.bin

  


  How to force ffmpeg to copy the data streams from input to output ?
