Discord music bot doesn't play songs
9 octobre 2023, par Gam3rsCZI have made myself a discord bot that also plays music(it's only for my server so strings with messages are in Czech, but code is in English).
Bot worked a while ago but now it stopped, and I don't know where the problem is


I'm getting these errors : HTTP error 403 Forbidden Server returned 403 Forbidden (access denied) and

Convert mp4/mov/... to mp4 with fluent-ffmpeg
13 octobre 2023, par Sam LeursI have a lambda function which reads a video from s3, converts it with fluent-ffmpeg and streams the video back to (another bucket in) s3.


This is the code so far :


ffmpeg()
 .input(readstream.Body)
 .format('mp4')
 .addOutputOption("-preset veryfast")
 .addOutputOption("-movflags frag_keyframe+empty_moov")
 .addOutputOption("-crf 28")
 .output(writestream, { end: true })
 .on('error', (err, stdout, stderr) => {
 console.log(err);
 console.log('Stdout: %o', stdout);
 console.log('Stderr: %o', stderr);
 })
 .run();


With an input mp4 file, this code works, but with a mov-file it fails. I get the following error :


Error: ffmpeg exited with code 1: Error demuxing input file 0: Invalid data found when processing input
pipe:0: Invalid data found when processing input
Cannot determine format of input stream 0:0 after EOF
Error marking filters as finished
Conversion failed!

Is it possible to convert multiple filetypes with one fluent-ffmpeg chain. If not, can someone help me to make a chain for mov ?

Cropping a video from Sony A7 Camera using ffmpeg
23 octobre 2023, par Mike SlinnI want to crop a video file created by a Sony A7iii camera, so only the portion from 0:51 through 2:45 is extracted.
The camera adds streams that need to be ignored.


ffprobeshows the error on input stream 2, however the problem I am reporting deals with input stream 3, which is a data stream, and is not required. I want to exclude input stream 3, then deal with input stream 2.

I tried various incantations that specified permutations of
-mapoptions, but only dug myself a deeper hole.

How might I perform the extraction ? I am not interested in preserving extra streams, I just want the main video and stereo audio streams.
