ffmpeg not working

[yashkhandelwal05]

I have tried out both ffmpeg.kill() and ffmpeg.stdin.destroy() But still it's not working.

I found a fix, you need to manually close the stdin stream, after the tab stream was closed:

stream.on("close", () => {
    ffmpeg.stdin.end();
});

[yashkhandelwal05]

What is the use of the close callback for stream ? Will the await stream.destroy() line take time to close off the stream?

[SamuelScheit]

yes, it does. The stream has a delay of ~a second and it waits for the stream to end and send the last packet, until it closes the stream

[yashkhandelwal05]

For longer duration videos>= 30 mins it's not working. The stream close is working but ffmpeg.stdin.end() is not working and I am not getting a close callback. await new Promise((resolve) => { ffmpeg.stdin.end(); ffmpeg.on('close', (code) => { console.log(FFmpeg process exited with code ${code}); resolve(); }); });

 I am using spawn instead of exec. Can that affect as well?

[yashkhandelwal05]

I have tried using both exec and spawn but still its not working with videos of around 1 hr duration

[SamuelScheit]

I've let it run for an hour and it closes without problems:

[yashkhandelwal05]

If I am not using : ffmpeg.stderr.on("data", (chunk) => { console.log(chunk.toString()); }); Then the ffmpeg is not ending but when I am using this it's getting ended. I guess this part of code should be optional as I don't want to have a continuous logging.

[yashkhandelwal05]

Can you please try removing this part: ffmpeg.stderr.on("data", (chunk) => { console.log(chunk.toString()); }); And check whether it's working or not

[yashkhandelwal05]

There is also problem with this line: const ffmpeg = exec(ffmpeg -y -i - -c copy output.mp4); I am getting this error. Can you please check?

@SamuelScheit any update?

[SamuelScheit]

works for me, can't replicate
