You need to justify that statement. Because if they do not match, then

Hello,
I am using ffmpeg to transcode video in live stream - both input and
output are MPEG-TS multicasts (single program transport stream). Input
MPEG-TS contains EIT (EPG) and I want to copy it to the output.
Current ffmpeg treats EPG/EIT as private data stream. I have mapped it
to be copied to

Hi, the patch file I have sent via git-email does not seem to be listed in
the patchwork list of patches. Can somebody comment on the file/mimetype,
and if everything looks good?
First time submitting a patch, please let me know if there is any other
thing I need to do.

First of all: I only looked at the sei_user_data stuff yet.
