ffmpeg itsoffset doesnt apply offset to mp4
26 juillet 2019, par bruxThe following command mixes an mp4 and an mp3 together, keeping the audio from the mp4.
ffmpeg -i video.mp4 -i audio.mp3 -map 0:v -c:v copy -filter_complex '[0:a][1:a]amix[aout]' -map '[aout]' -shortest out.mp4
The command works as expected.
Now I want to offset the mp4 file (both the audio and video stream of the mp4) so that there is a delay of 500ms at the start of the mp4, here is my command :
ffmpeg -itsoffset 00:00:00.500 -i video.mp4 -i audio.mp3 -map 0:v -c:v copy -filter_complex '[0:a][1:a]amix[aout]' -map '[aout]' -shortest out.mp4
This doesnt work as expected, the output doesnt have the expected delay of 500ms at the start of the mp4 streams. It appears the output is just the same as the first command I ran.
The version of ffmpeg I am using is :
ffmpeg version n4.0-39-gda39990
Here are the files I’m using :

finishedNote :
As you can see I have console the URL which I have made dynamic URL.In addition, I directly got statusCode = 1. When I paste the same URL in my local termial and hit the enter then my streaming starts.
So the question is why it is not working in live ?
