[FFmpeg-devel] [PATCH 1/4] get_bits: move check_marker() to mpegvideodec.h

[Anton Khirnov]

It is only used by mpegvideo-based decoders - specifically mpeg12, intelh263,
ituh263, mpeg4video.
---
Resending the set rebased against current master (there conflicts with
2d764069be3b4092dc986467660607d922023332) and with patch 04 skipped, as
Andreas pointed out issues with it. It is not needed by the other
patches, so can be left out for now.

Apparently Paul has withrawn his objections and Lynne approved the
previous iteration on IRC, so will push this in a few days if nobody
objects.
