Subject: pes.c: make sure H264 stream has aud
X-Git-Tag: 1.2.0-pre1~5914
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=d5cec4585d66dd4c67c496ed29a163436774b793;p=vlc

pes.c: make sure H264 stream has aud

TS-stream needs aud-nals, but didn't find any confirmation yet if ps needs those too,
so I assume it does. Maybe it would be better just to check first nal and set boolean for
adding aud.
