Burning subtitles into video using ffmpeg overlay on react native
25 avril 2023, par YoussefI 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);
 });
 }

Gstreamer missing Decoder meta/x-gst-fourcc-mebx
27 juin 2024, par ZZakI'm currently working with GStreamer in a Linux environment and encountered an issue after upgrading from GStreamer 1.18 to 1.22. While trying to process a video file, I received the following error message :


[hevc @ 0x7f26101eba00] Skipping NAL unit 62 
[hevc @ 0x7f26100fcd40] Skipping NAL unit 62 
[hevc @ 0x7f2610113e00] Skipping NAL unit 62 
missing-plugin, type=(string)decoder, detail=(GstCaps)meta/x-gst-fourcc-mebx, name=(string)"meta/x-gst-fourcc-mebx\ decoder";




Also discoverer gives

Source video is with .MOV video(made by iPhone) with I420_10LE format and not corrupted.
Also it's data (streams) :

This suggests that a GStreamer plugin with a decoder for the MIME type meta/x-gst-fourcc-mebx is missing from my environment. I didn't face this issue with version 1.18, but it started occurring after the upgrade to 1.22.
I've tried searching for information about this specific decoder, but I haven't been able to find any relevant details.
Could you please provide any insights or guidance on how to handle this MIME type, or which plugin should be installed to provide the necessary decoder ? If this decoder is part of a proprietary plugin or requires a specific setup, any information on how to proceed would be greatly appreciated.
Thank you for your time and help !
