Rintaro Kuroiwa 0a3ef49c11 Change {luma,chrome}_weight_flag to arrays
- The flags were overwritten in a loop and therefore only stored the
  last value of the flag.
- Change the fields into arrays so that the flags are not overwritten.

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.

Rintaro Kuroiwa 15fd745fa7 Remove redundant flags in H264SliceHeader
- luma_weight_l0_flag, luma_weight_l1_flag,
  chroma_weight_l0_flag, chroma_weight_l1_flag were there but not set.
- The user should use the values in pred_weight_table_l0 and
  pred_weight_table_l1 instead which are set.

Kongqun Yang 24ba12c18e Remove escape parameter in NalUnitToByteStreamConverter
The spec actually requires all NAL units to be escaped, so there
is no need to escape it again.

NAL byte stream is one demarcation method; NAL unit stream is another
demarcation method. Regardless of the demarcation method used, the
requirement for NAL unit is the same. See the last paragraph of
7.4.1 NAL unit semantics on the requirement on emulation prevention bytes.

Kongqun Yang c223bc9144 Keep slice data partition NALs in clear
CENCv3 recommends only encrypting video data in slice NALs. Slice
data partition NALs should not be encrypted.

In the code, differentiate is_vcl and is_video_slice. They are the
same for H265; for H264, vcl NALs include slice data partition NALs
but video_slice NALs do not.

Rintaro Kuroiwa 7a4a40acb8 Change values for slice header attributes
- nalu_data points to the beginning of the nalu, instead of
  beginning of the slice header which excluded the nalu
  header.
- nalu_size is the size of the whole nalu.
- header_bit_size calculation is corrected. The size used to exclude
  emulation prevention bytes.

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 f9bf197f2b Fix bug in VPx codec configuration.
Before, we converted the WebM configuration to MP4 in the video
client, however this lead to a bug when fields were missing.  So
now don't convert until the cluster parser so the extra info from
the stream can be added.

This also fixes a bug where the value was not printed in the warning
logs.
