10- and 12-bit DNxHR use the same DC coefficient decoding process and
VLC table, just with a different shift value. From SMPTE 2019-1:2016,
8.2.4 DC Coefficient Decoding:
"For 8-bit video sampling, the maximum value of η=11 and for
10-/12-bit video sampling, the maximum value of η=13."
A sample file will be uploaded to show that with this patch, things
decode correctly:

H264ParamSets has its SPS/PPS stored raw (SODB) and needs to be
converted to NAL units before sending them to MediaCodec.
This patch adds the missing convertion of the SPS/PPS from SOBP to RBSP
which makes the resulting NAL units correct.
Fixes codec initialization on Nexus 4 and Nexus 7.

P1, P2, and P3 are respectively the text versions of PBM, PGM and PPM
files.
We can not obtain the buffer size using av_imgage_get_buffer_size() as
every pixel in the picture will occupy a random size between 16 and 32
bits ("4 " and "231 " are such example).
Ideally, we could look for the next header (or EOF) in the bytestream,
but this commit is meant to fix a decoding regression introduced by
48ac4532d4.
Fix Ticket #5670
(cherry picked from commit c5566f0a94)
The encode function is supposed to just return 0 on success.
This stems from a mixup with the return value of decode functions.

This commit fixes a broken build when compiling libavcodec with LLVM
compiler. These assembly files use non-standard format that is only
supported by GCC compiler. It would be nice to use a common standard
format. With this patch, both GCC and LLVM can build and generate the
same objects.

Increase buffer dequeue timeout when the codec needs to be drained as it
could happen that no input buffer is available when we receive a null
packet for the first time (meaning we are unable to signal end of stream
and mark the codec as draining).
Fixes potential loss of last frames after sending a null packet.
