ffmpeg concat skips frames near end of each subclip
3 janvier 2024, par calvinusesyourcodeSo I have some video files to concat but in the resulting video the last few frames of each subclip are buggy. Imagine in the last 5 frames the first 3 frames are skipped and so at the end of each clip it seems to jitter.


It should be virtually impossible for my input videos to have any differences between them, as they were all recorded on the same iPhone and all converted with the same command :


command = [
 'ffmpeg', '-y',
 '-i', input_path,
 '-vf', 'scale=1080:1920',
 '-r', '30',
 '-c:v', 'libx264',
 output_path
 ]
subprocess.run(command, check=True)



I have tried re-encoding instead of merely copying and adding
-r 30
but that doesn't seem to work.

subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-c", "copy", output_path])



subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-r", "30", "-c:v", "libx264", "-c:a", "aac", output_path], check=True)



Somewhere someone said to open in VLC and do a frame-by-frame, reporting that "the frames are actually there, just not visually when watching normally". In my case the frame-by-frame reveals the frames are indeed being skipped.

UPDATE : I am thinking that the way I am converting my files from .mov to .mp4 is the problem. Please suggest the best way to convert from iPhone 4k 60fps .mov files to nice 1080p 30fps .mp4 files. I know I could just use handbrake but I am trying to be a man here xD. Perhaps handbrake has a

.

UPDATE 2 : re-encoding the videos before concat with
-c:v libx264
fixes the problem... which seems weird because that is how they were originally encoded...

Invalid data found when processing input for mp3 file in ffmpeg
15 juillet 2023, par Sai ChaithanyaMy custom compiled FFmpeg build is unable to read mp3 files, suddenly. Interestingly, the custom compiled FFmpeg build generated the mp3 file. For the past 1 year, it was successfully reading the file. I checked with the official FFmpeg build, and it works, so at least the file is not corrupted.
