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.

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 ?

ffmpeg - cut without reencoding and strange behaviour : application provided duration is out of range for mov/mp4 format [closed]
27 août 2023, par user2707175In Ubuntu 18.04 I quite often used the following command for trimming part of the video without re encoding (which means without any quality loss).


ffmpeg -ss 00:06:00 -i DSCF5984.MOV -t 00:07:00 -c copy DSCF5984_A_wszystkie.MOV

Not so much time ago I moved to Ubuntu 22.04. Still having the same video camera and still using the same format for recording, when using the command as above I'm getting quite strange error and the behavior is unexpected. In this case mov file is 40 sec file. I want to get 7 seconds fragment starting from 6 second (thus from 6 to 13 sec). Instead of this I get very short fragment from the beginning of the file. I don't even know how long as none of video players want to display its length. Probably it's 1-2 sec. Thus it's not only, I get this error, but ffmpeg doesn't work. In theory I have the newest version available for ubuntu 22.04.
