Some legacy applications such as AVI2MVE expect raw RGB bitmaps
to be stored bottom-up, whereas our RIFF BITMAPINFOHEADER assumes
they are always stored top-down and thus write a negative value
for height. This can prevent reading of these files.
Option flipped_raw_rgb added to AVI and Matroska muxers
which will write positive value for height when enabled.
Note that the user has to flip the bitmaps beforehand using other
means such as the vflip filter.
Currently, the COC marker overrides the SOP marker bit.
However, only the COD marker may set this value. This
patch fixes this bug.

The number of declared vdpau formats can vary depending on which
version of libvdpau we build against, so the number of pix fmts
can vary too. Let's make sure we keep those numbers in sync.
Some new warnings regarding use of empty macro parameters has
been added, so adjust some x86inc code to silence those.

No audio stream is created unconditionally and if none has been created,
no packet with stream_index 1 may be returned. This fixes an assert in
ff_read_packet() in libavformat/utils reported in ticket #8782.

Added VDPAU to list of supported formats for HEVC10 and 12 bit formats
also added 42010 bit to surface_parameters and new VDP chroma formats to
VDPAUPixFmtMaps
Add HEVC 420 10/12 Bit and 444 10/12 Bit support for VDPAU
YUV444P10 is defined as the 444 surface with 10bit valid data in LSBs
but H/w returns Data in MSBs Hence if we map output as YUV444p16 it
is filtering out the LSB to convert to p10 format.

Currently the next thread's context is updated from the previous one's
if the codec descriptor is not marked as intra-only. That is not
entirely correct, since that property does not necessarily imply
anything about how a specific decoder implementation behaves.
Instead, use the presence of the update_thread_context() callback to
decide whether an update should be performed. Fixes races in CFHD,
should cause no behaviour change in any other decoders.
add probeaudiostream for get audio stream's codec_name,codec_time_base,
sample_fmt,channels and channel_layout.
