Kongqun Yang ec904f3f79 Add a new test to exercise emulation prevention after encryption
Also added a few more command line flags for end to end test:
- no-remove_temp_files_after_test: do not remove test artifacts after
  test
- encryption_key, encryption_iv: allow injecting encryption key/iv from
  command line

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 5edd290694 Fix WebM not encrypted when clear lead is set to 0
- Also regenerated test content to insert an iframe every one
  second: ffmpeg -i source.webm -auto-alt-ref 1 -g 30 out.webm
  This makes sure the content is actually encrypted with one
  second clear lead in end to end test.

Kongqun Yang d501b457d0 Fix WebM keyframe detection in BlockGroup
The right way to detect the presence of a keyframe in a BlockGroup
is to look for the absence of the ReferenceBlock element [1].

Closes b/30433206

KongQun Yang 91b43773fd Update hevc test file to have more than one key frames
This is needed to test encryption in end to end test since the video
is segmented in gop boundary by default. Due to the existence of clear
lead, the first segment is always left in clear.

Kongqun Yang e5b6096857 Generate tkhd and pasp boxes properly with non-square pixels
- Width/Height in tkhd box should be display resolution instead of
  coded resolution.
- pasp was not generated earlier.
- Assuming SAR as 1:1 if it failed to be extracted successfully.
- Also update test files for mp4_media_parser_unittest.

This fixes Issue #35.

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.
