Jacob Trimble 8e85862bda Ignore unsupported H26x streams.
This adds a new path when parsing MPEG2-TS streams to ignore unsupported
streams.  This allows extracting supported streams when some of the
streams are unsupported.  For example, you can extract audio from a
file that has unsupported video.

KongQun Yang 3f909fa551 [HLS] Support HDR signaling, i.e. VIDEO-RANGE attribute
- Parse and extract transfer_characteristics from H264/H265 VUI
  parameters.
- Set VIDEO-RANGE attribute in HLS according to HLS specification:
  https://tools.ietf.org/html/draft-pantos-hls-rfc8216bis-02#section-4.4.4.2
- Also added an end to end test.

Fixes #632.

Kongqun Yang 277c5b23c0 Allow generating avc3 / hev1 from TS and Wvm files
Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.

Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.

The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.

Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.

Kongqun Yang 09891dcd9e Fix access unit detection problem for H264
In H264, there may be multiple consecutive video slice NAL units
in the same frame. The original code assigns a new access unit
for every video slice NAL unit, which is incorrect.

Fixes #134.

Jacob Trimble abb1abf5c5 Rename StreamInfo::extra_data to codec_config.
Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.

This add several unit tests for EsParserH26x to test the various
NAL unit orders and access unit contents.  Some tests are disabled
and will be fixed in another patch.

Jacob Trimble a789dc6d3c Replace Nalu::InitializeFrom* with Initialize.
Replaces the InitializeFromH264 and InitializeFromH265 methods with
a single Initialize method that accepts a CodecType.  Also moves the
CodecType enum from NaluReader to Nalu.

Jacob Trimble 0803e31836 Read SPS/PPS Nalus from decoder configurations.
Now the AVCDecoderConfiguration and HEVCDecoderConfiguration classes
will read the Nalu from the blocks, meaning they will store a
vector of Nalu objects for the data.

Also added H.265 to the Nalu class and added argument to NaluReader
to read H.264 vs H.265 Nalus.

it to its own class.  Also added support for length-prefixed
NALU splitting for use with the encrypting fragmenter.

Kongqun Yang 3a5fdd2d9c Fix incorrect width/height in VisualSampleEntry for mp2t stream with cropping
Cropping is necessary if width/height are not exactly disivible by 16 due
to 16x16 macroblock size.

The width and height fields in VisualSampleEntry must correctly document
the cropped frame dimentions (visual presentation size) of the AVC stream
that is described by that entry.

Also fixes width/height in input mp4 and wvm streams if the values in
VisualSampleEntry / metadata do not match with the values in
AVCDecoderConfigurationRecord (SPS).

Rintaro Kuroiwa c3c971ebd9 Add pixel_{width,height} to VideoStreamInfo
- Added logic to container parsers to extract pixel width and height.
- If the container doesn't contain the pixel width and height of the
  stream and the stream is H264, this parses the SPS to get the
  sar_width and sar_height.
- If extracted sar_width and sar_height are 0s then they imply 1s.
- Add hb2_v_frag.mp4 for test media. This does not have a
  'pasp' box and has sar_width = 8 sar_height = 9.

consideration.
