[FFmpeg-devel] [PATCH 14/14] avdevice/iec61883: #if unused code away, fix -O0 compilation

[Andreas Rheinhardt]

iec61883_parse_queue_hdv() is only called when the mpegts-demuxer
is available and can be optimized away when not. Yet this
optimization is not a given and i fails with e.g. GCC 11 when
using -O0 in which case one will get a compilation error
because the call to the unavailable avpriv_mpegts_parse_packet()
is not optimized away. Therefore #if the offending code away
in this case.
