Your reply is confusing. I will attempt to clarify:

libav-u...@ffmpeg.org is the mailing list for user questions involving
the FFmpeg libraries.

ffmpeg-user@ffmpeg.org is the mailing list for user questions involving
the FFmpeg command-line interface tools.

Carl,
Why we should be careful with the fps filter?
What's wrong with it?

That’s hardly the same command, as it does not even output the same error.

At least give some people the satisfaction that you’ve at least tried to 
search. Cargo-cult copy-and-paste shows more effort than this.

ffmpeg -i udp://@239.203.59.225:50100 -c:v copy -c:a copy -f mpegts 
stream_dump.ts

Also, MPEG4 Part-2 is a codec, not a format.

ffmpeg -codecs | grep 'MPEG-4 part 2'

Hi All:

   Do someone encountered this situation like the attach showed ?

   If so ,could you give some tips about it ?

   What's the problem could it be ?


A couple of things... "libav" and "ffmpeg" are not the same project. So please 
don't send e-mails to "libav-u...@ffmpeg.org" but to "ffmpeg-user@ffmpeg.org". 
Further please note "ffmpeg-de...@ffmpeg.org" is for the development of ffmpeg 
only and you should communicate with ffmpeg-user@ffmpeg.org for all user and 
usage related questions.


Now you say you've attached something. Well, your e-mail didn't come with 
anything. Could you please send a new e-mail to "ffmpeg-user@ffmpeg.org" and 
with a complete command line of what you were trying to do, possibly some 
samples and a clean description of what you are trying to do?


And please try to avoid asking what has already been answered through the 
documentation, the examples and the various guides at 
https://ffmpeg.org/documentation.html


Thank you.

Hi Robert,

if not, maybe exiftool is a viable alternative...

[FFmpeg-user] Writing EXIF metadata

Hi,

is it possible to add EXIF metadata like title or description to a JPG or
PNG image using ffmpeg on the command line (or via api but that's probably
for the other list)?

I did not find anything regarding that in the docs.

Thanks in advance,
