Hi all,
This patchset adds support for the APM files used by Rayman 2.
It has been tested against all *.apm files in the game folder.

Hi,
I'm starting to work on a patch to add encryption support for
fragmented MP4 following the cenc scheme to FFmpeg. I'm writing
to ask if anyone had already started or planned such a patch,
to avoid duplicate work or to step on anyone's toes.
The goal would be to extend the current support for
Log as [opengl @ 0xaddress] instead of [opengl outdev @ 0xaddress].

Hello, everyone.
I'd like to request a change in order of DVB segments to be in line with ETSI
300 743. Basically Region Composition Segment should come before CLUT segment.
This caused problems on legacy STBs namely Amino A110.
In the ETSI EN 300 743 V1.6.1 (2018-10) section 4.4 it is written

I only had concerns with the length of the help, they were addressed. I

Why? The described behavior seems quite fine. Aborting the encoding
process a little earlier would be fine, but it's hardly a critical
issue.

If they do, that's a serious problem by itself, and a protection in the
command-line tool will only hide it.

This allows having a video stream as reference stream when using the segment
muxer:
The video stream serves as a kind of 'heartbeat' to ensure that VTT segments
are generated regularly, even when there aren't any subtitle packets for a
while.
Example:

It's often not obvious how option constants relate to numerical values.
Defaults are sometimes printed as numbers and from/to are always printed as
numbers.
Printing the numeric values of options constants avoids this confusion.
It also allows to see which constants are equivalent.
