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 ?

MP4 file starts from a non-key frame [closed]
1er octobre 2023, par userDtrmI have used the following ffprobe command to analyse a .mp4 file.




ffprobe -i <input /> -show_frames - select_streams v:0 -print_format flat &> save_to_file.text



It produces the following output.

As seen in this output, the 1st frame appears to be a P frame. I'm curious as to how will the decoder decode this frame without a preceding I frame (key frame) ? The P frame will not have enough information to reconstruct the image from its residual data without the key frame.
