Saving rtmp stream to mp4 file problem

[michalslime]

Hi Team,

Im trying to write ffmpeg command, that takes rtmp stream and saves it to mp4 file. The following command works: ffmpeg -i rtmp://rtmp.global.cdn.vindral.com/publish/sk_b75a2aa5-9d18-4f44-8d38-cb33ac31c84b -vcodec copy -acodec copy -f mp4 output.mp4

But my command written in fluent-ffmpeg doesnt work. I guess it's because of wrong options that i used.

Thank you in advance for checking my code below!

Version information

• fluent-ffmpeg version: 2.1.2
• ffmpeg version: 4.4.2
• OS: Ubuntu 22.04.1

Code to reproduce

const ffmpegStatic = require('ffmpeg-static'); const ffmpeg = require('fluent-ffmpeg');

ffmpeg.setFfmpegPath(ffmpegStatic);

ffmpeg() .input('rtmp://rtmp.global.cdn.vindral.com/publish/sk_b75a2aa5-9d18-4f44-8d38-cb33ac31c84b') .addOptions([ '-vcodec', 'copy', '-acodec', 'copy', '-f', 'mp4' ]) .output('output.mp4') .on('error', (error) => { console.error(error); });

Expected results

File with recorded stream

Observed results

Not even an error message

Same problem. use command.kill('SIGINT') to stop. but no MP4 file. use cmd ffmpeg -i xxx -c copy -y -f mp4 output.mp4 and ctrl-c mp4 file can save.
