This option allows to add a prefix to the segment list entry filenames.

Also set by default the list entry filenames to the corresponding
segment basename, consistent with the HLS muxer.

Based on an idea by Steven Liu <lingjiujianke@gmail.com>.

We will likely want to add new fields to it in the future, so this is
needed to avoid breaking ABI.

Based on the code by Rémi Denis-Courmont <remi@remlab.net> from VLC.

XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

The file was written in 2006, it was never updated nor really used as
reference for SOC-like programs.

That example shows how the decoding process works, not only the
demuxing.

Before, it just returned width/height. Correct is width/height*sar.

That way it is consistent with DAR as in probe output and setdar.
