Hello All,
ffprobe does not seem to be able to retrieve all the metadata entries within a
container.
I am using ffmpeg version 4.1 for MS Windows (build 20181017).
My purpose was to give names to the 2 subtitle streams (mov_text) of my movie.
Therefore, I did it like this :
ffmpeg -i

Hi All,
I don't understand why neither ffmpeg nor ffprobe detect presence of closed
captions within MP4/H.264 in some video streams when VLC does.
Let me explain this... In the past 20 years, I have been working in several
countries over the world and I bought official DVDs. Not duplicates ;-)

Hello All,
Is there a maximum value for the "stepsize" option of vidstabdetect ? I don't
see any in the documentation.
I first tried this on Windows :
ffmpeg -i "INPUT.mp4" -an -vf
vidstabdetect=shakiness=10:accuracy=15:stepsize=6:result="TRF06.txt" "dummy.mp4"
and then this :
ffmpeg -i
is a
very very shaky one (taken from a high speed boat).
Best regards.

Hello All,
I don't understand how ffmpeg/ffprobe manage some metadata of audio streams.
Let's take a simple example :
ffmpeg -i INPUT.mp4 -c copy -metadata:s:a:0 "title=5.1" OUTPUT.mp4
The result is :
1- ffprobe is not able to retrieve the audio title of the resulting file,
whatever are the
y ffprobe in its TAG section.
Therefore I repeat my question to All : why ffprobe does not retrieve the audio
and subtitle stream titles while VLC and exiftool do it properly?
Is this a designed behavior ?

Hello All,
I'm not a developper. Therefore I'm not able to analyze the ffmpeg/ffprobe
source code.
I observed that the command below seem to work properly when adding a title to
an audio stream within an MP4 file :
ffmpeg -i INPUT.mp4 -c copy -metadata:s:a:0 "title=mono" OUTPUT.mp4
Thank you Moritz. I really apreciate your kind answer.
But ... I don't understand what you are planning to do.
Please tell me if I'm right or wrong :
- ffprobe/ffmpeg will display the data contained in the "name" atom to
stdout/stderr
BUT
- ffmpeg will NOT be able to copy the audio stream
Thank you again Michael for your kindly help.
Now I have an account to edit existing Wiki pages.
My question is how can I add a new page with my contribution before linking it
to an existing page ?

Thank you Michael,
I tried to register a new account at https://trac.ffmpeg.org/register
There is an antispam check in this page. I don't know what to answer to the
first question about the project name.
What can I do ?
