FFMPEG audio through strip, cut, concate is out of sync
3 octobre 2022, par CospelI'm trying to solve several use-cases, first is stripping audio out of the video (.mov, .mp4, .mkv, ...). I'm using this command (for removing video stream and copying audio stream) :


ffmpeg -i movie.mov -vn -c:a copy strip_audio.aac



However, the resulting audio (strip_audio.aac) is shorter (by a few ms) than audio detached from movie.mov in iMovie. strip_audio.aac is also progressively out of sync. See screenshot below, btw video audio and strip_audio.acc.


The second problem is that I'm trying to divide the video into small segments (3 seconds) and then concatenating them again. For creating chunks/cutting the video, I used this command :


ffmpeg -i video.mov -ss 00:00:00 -t 3 0000.mov
ffmpeg -i video.mov -ss 00:00:03 -t 3 0001.mov
...



Then I concatenate the segment parts via this command :


ffmpeg -f concat -safe 0 -i listfile.txt -c:v copy -vsync 0 concat-result.mov



However, in the first chunk, the audio is already out of sync at the beginning (there is a visible empty gap). And concatenating parts have small glitches between each other in audio tracks.


So my questions are :


- 

- Is it possible to strip audio via FFmpeg that will not be out of sync and has the exact length of the original audio ?
- Is it possible to merge chunks without any corruption/glitches ?
- Why is first chunk corrupted in beginning and how to solve it ?








I tried almost everything that I saw on StackOverflow, but I still, get a lot of glitches when concatenating and the out-of-sync audio. I have FFmpeg in version 5.0.1.




Update 1 :
If I create (just audio) chunks of .flac and then concatenate them, then there are no glitches between concatenating chunks. However, the first chunk is corrupted in the beginning and the audio stream is progressively out-of-sync. I found this repository which I used to create flac chunks and then concatenate audio.

Why is ffmpeg removing everything but the audio when cutting a video ? [closed]
12 juillet 2021, par CartClashI'm trying to cut a video into smaller parts using this ffmpeg command :


ffmpeg -i example.mp4 -ss 0:0:01.45 -to 0:0:04.48 -c copy trimmedVideo.mp4



However, when I run the command, only the audio remains. Here's a picture :



What could I be doing wrong to cause this ?

Run bat files sequentially (?) [duplicate]
27 février 2021, par RewossKyWith FFmpeg, I divide 1 video into 675 parts, this process can take a long time depending on the video quality. There are slowdowns towards the middle of the process. I think I'm experiencing freezes because the cpu cache is full. For this, I divided the process in two and added the codes to 2 separate bat files. All I want is to run the 2.bat file after the 1.bat file is running and finished.


start 1.bat start 2.bat exit


When I do this way, the 2bat file is running at the same time.
