avformat/udp: replace packet_gap with bitrate option
We haven't had a stable release since the packet_gap addition, so probably it
is worth reworking the option to something that makes more sense to the end
user. Also add burst_bits option to specify maximum length of bit bursts.
ff_h264_decode_ref_pic_list_reordering() and h264_initialise_ref_list()
do not have a const H264Context * as they modify the default_ref inside
that context.
- move get_avc_nalsize() inside h264_parser.c and make it use
H264ParseContext instead of H264Context. This helps fixing
fate-flv-demux.
- Also use is_avc/nal_length_size from the H264ParseContext in various
places instead of the H264Context one as that's the fields now filled
by ff_h264_decode_extradata()
- h264_parse: dont fail decode_extradata_ps() due to nal split failure.
Change by Michael to fix decoding of h264/ref_10.avi.

- SEI decoding doesn't have access to the debug flag in the codec context so a
few logging are dropped.
- naming of quincunx_sampling_flag and frame_packing_arrangement_type are kept
as they are in FFmpeg instead of respectively quincunx_subsampling and
arrangement_type used in Libav because the former match the specifications.
- don't reset the x264 build info once read in order to fix
fate-h264-lossless (change by Hendrik)
- H264Context.has_recovery_point and deprecated
AVCodecContext.dtg_active_format are set after ff_h264_sei_decode()
based on the SEI state since ff_h264_sei_decode() doesn't have access
to H264Context anymore.
- frame_packing_arrangement_type is not checked against <= 0 in
decode_postinit() since it is always read as a positive value with
get_bits(). This fixes a -Wtype-limits warning by GCC spotted by
Michael.
Side Notes:
- tested that ffprobe on the file from ticket #3652 still returns 4
keyframes
- tested that playback from ticket #3063 still works

lavd/v4l2: allow devices not implementing VIDIOC_G_PARM
Not all v4l2 devices implement the VIDIOC_G_PARM ioctl. This patch allow
ffmpeg to open such device and treat it the same as devices that do
implement the ioctl but returns that it do not implement the
V4L2_CAP_TIMEPERFRAME capability.
Allows to select a codec (encoder or decoder) only if it supports a
specific profile.
Adds ff_AMediaCodecProfile_getProfileFromAVCodecContext to convert an
AVCodecContext profile to a MediaCodec profile. It only supports H264
for now.
The codepath using MediaCodecList.findDecoderForFormat() (Android >= 5.0)
has been dropped as this method does not allow to select a decoder
compatible with a specific profile.

avcodec/ffv1dec: fix some unsupported pix_fmt
When checking pix_fmt mapping, some bitstreams are mapped to an
incorrect pix_fmt instead of being rejected (ENOSYS).
Actually, such bitstreams are not supported (FFmpeg encoder does not
produce such bitstream, such bitstream may come only from another
encoder for the moment).
- JPEG 2000 RCT 11/13/15/16 bit depths are mapped to a 8-bit FFmpeg
pix_fmt (e.g. bgr0), which is not expected.
- JPEG 2000 RCT 9/10/12/14 bit depths with alpha are mapped to a
FFmpeg pix_fmt without alpha (e.g. AV_PIX_FMT_GBRP9 for 9-bit with
alpha), which is not expected.
The order for choosing the pix_fmt is changed to the one used by YCbCr
selection (<=8 bit first).
" && !f->transparency" is added to the other lines.

possibility to decrease memory usage if soft compensation is ignored
H264Context is kept locally as it is currently needed for logging
(h->avctx as log context) and for is_avc and nal_length_size. These
later fields will later be obtained when the extradata parsing is
decoupled from the decoder. This code will be updated accordingly when
that commit is merged.
- a local GetBitContext is created for the various
ff_h264_decode_seq_parameter_set() attempts
- just like the old code, remove_sps() is adjusted so it doesn't remove
the pps.
Fixes decode with Ticket #631
http://ffmpeg.org/pipermail/ffmpeg-user/attachments/20111108/dae58f17/attachment.mp4
but see next point as well.
- ff_h264_update_thread_context() is updated to work even when SPS
isn't set as it breaks current skip_frame code. This makes sure we
can still decode the sample from ticket #631 without the need for
-flags2 +chunks. (Thanks to Michael)
- keep {sps,pps}_ref pointers that stay alive even when the active
pps/sps get removed from the available lists (patch by michaelni with
additionnal frees in ff_h264_free_context() from mateo)
- added a check on sps in avpriv_h264_has_num_reorder_frames() to fix
crashes with mpegts_with_dvbsubs.ts from Ticket #4074
http://samples.ffmpeg.org/ffmpeg-bugs/trac/ticket4074/mpegts_with_dvbsubs.ts
- in h264_parser.c:h264_parse(), after the ff_h264_decode_extradata() is
called, the pps and sps from the local parser context are updated with
the pps and sps from the used h264context. This fixes fate-flv-demux.
- in h264_slice.c, "PPS changed between slices" error is not triggered
anymore in one condition as it makes fate-h264-xavc-4389 fails with
THREADS=N (Thanks to Michael)
