I need to map this x.264 clip into a matroska container using ffmpeg:
ffmpeg -i f-0.mp4 -c copy f-0.mkv
Here is the ffmpeg console output:
ffmpeg -i f-0.mp4 -c copy f-0.mkv

The result seems good, playing with well synchronized audio and video. However, MediaInfo shows a new item under Audio (that the original clip didn't have):
Delay relative to video : 1mn 5s
Here is the Mediainfo from the original f-0.mp4 file:

Mediainfo from the f-0.mkv output:

There is no delay whatsoever and no reason to insert a delay.
I am concerned that this information (Delay relative to video) be used by some players or other applications as a delay that should be corrected. Is there a way to prevent this from happening?

How can i fix this ;( help me....
it works well if i tpye only "'ffmpeg -i ' + video_path + ' -q:v 2 -f image2 ' + frame_path + '\image_%6d.jpg'" on prompt with specific path name.
but it doesn't work in .py (i used code in .py-> os.system('ffmpeg -i ' + video_path + ' -q:v 2 -f image2 ' + frame_path + '\image_%6d.jpg')

Make use of helpful (& more secure) built-in packages/functions:
from os import path
import subprocess as sp
sp.run(['ffmpeg','-i', video_path,
'-q:v','2','-f','image2',
path.join(frame_path,'image_%6d.jpg')])
I suspect your call went nuts because of unescaped backslashes in the file paths. subprocess.run essentially avoids that nastiness from making a system call.

You can't re-use labels (a.k.a. "pads", unintuitively) from filter outputs. So you can't use si more than once.
Add the split filter to make copies:

I want to obtain a different raw video for each frame of an MP4 file.
My instruction works in an old version of ffmpeg but not in the new one.
In the mp4 file there are 137 frames. It is checked. The versions are installed on different machines.

In the latest version, I expect 137 files but the amount is 136.
The old version did not have support for edit lists. Technically, some frames are not meant for presentation but only as reference, but since you want all frames, use
ffmpeg -ignore_editlist 1 -i ./video.mp4 -vsync 0 -c:v rawvideo -s '1920x1080' -pix_fmt gray frame%08d.raw
When I extract all frames from a video, FFmpeg lose one frame. I tried multiple options, like adding more parameters to the function, but none of them worked.

I'm a little noob with ffmpeg and I tryed to find a solution with google and don't find.
Without setsar=sar=1 I got the error about two different sar
[Parsed_blend_0 # 0x14bb0e0] First input link top parameters (size 1080x720, SAR 8:9) do not match the corresponding second input link bottom parameters (1080x720, SAR 1:1)
