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.

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

The original code accumulates sample durations in seconds (double)
and then generates new segment / cluster by comparing the accumulated
value with configured value.
There may be loss of precision when accumulating values in double.
For example, with a GOP of 96 frames and frame rate of 24 fps; the
accumulated frame duration for 96 frames is 3.999999999999, which is
very close to 4.0 but not 4.0. Problem would arise if segment
duration is set to 4. The created segments would have a duration of
8 seconds instead of 4 seconds.
The new code accumulates sample durations in uint64_t relative to
input time scale; the configured segment duration will be converted to
timescale for comparison. This avoids loss of precision.

packager/third_party/libwebm/libwebm.gyp:libwebm -> becomes target libwebm

- Another minor change in segmenter_test_base: scoped_refptr can
be passed by value, remove ".Pass".
Change-Id: I31f0cf74c5ad0aba8890d3b1845155d63d7326a0
* Changed Segmenters to accept StreamInfo rather than MediaStream
to help in testing.
* Changed MemoryFile behavior to mirror local file:
* Read non-existent file is an error.
* Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.
Change-Id: I339e35597ca4661b7a26c6fdbbfa2f9f511c7da0
- Parse vp9 bitstream to get vpx codec configuration
- Add subsample encryption for vp9
- Also fixed a bug in VP9 parser if segmentation update_map is enabled
Change-Id: I69dc97088aa38c94c6d37fdbcf3d9cfc942a3df6
- Add Box::WriteHeader and Box::HeaderSize methods. The concrete
box implementations should not need care about whether it is a
Box or FullBox normally.
- Rename Box::ReadWrite to Box::ReadWriteInternal to make it clear
that it is an internal methods. Make it private so it cannot be
incorrectly called in box implementions.
- Make an internal implementation of ComputeSizeInternal to compute
box size. |atom_size| is updated in ComputeSize, which wraps
ComputeSizeInternal.
Change-Id: I3fbcf8c527581b676d9d13f1ac1dd798da7c4d5f
* Added WebM muxer that supports both single and multi-segment modes.
* WebM muxer supports MPD generation.
* Enabled WebM muxer and demuxer in packager.

Also update the code to generate CompressorName in VideoSampleEntry
for both AVC1 and various VP codecs.
Change-Id: I2355f8008a72806e852aa1ec6c80e9141b97d963
Also includes its dependencies, like media/base/text_track_config.*
and media/filters/webvtt_util.h

- Neither live with or without key rotation did not output the right
result.
- No key rotation: did not produce any ContentProtection element.
- With key rotation: did not have DRM specific ContentProtection.
- To get key rotation working with shaka player, <cenc:pssh> elements
are removed.

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).
Issue: 39

- Because MpdBuilder no longer sets ContentProtection, live was broken.
- For key-rotation, <cenc:pssh> element is updated.
Change-Id: I45bb80a12faff39ccf5deb82439c0732ed9cea59
This fixes a circular dependency of media_base depends on filter and
filter depends on media_base.
Also added code to extract sar in WvmMediaParser if it is not yet
extracted when setting extra_data.
Change-Id: I1b5aef2444e4134c9b6663911ac5e5c4c220404a
- 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.

The segment duration was not reset after segment was finalized. It
was reset after adding one sample. This new sample was added to the
new fragment but was not recorded in the new segment, which resulted
in off-by-one error in the segment generation.
Change-Id: I1f9e00591be6b897773bf6caf94409b4bcd2277f
- The UUID and DRM name can be fetched from KeySource.
- Add ProtectedContent message to MediaInfo. The message contains basic
information for the protected content, such as the default key ID for
the content.
- The message is required to separate Representations with different
content protection information into different AdaptationSets.
Change-Id: Ib9dc834ae0abf93b7ca0acdf52a865b1394a4816
- 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.
Change-Id: I4a06ce95582547bec19adb7905e7612c5a1f359e
- The fields used to be repeated but there is no use case at the moment.
- DASH IOP explicitly disallows segments with multiple tracks.
Change-Id: Ia0af2048210c546dfaa178735605a81052ea1123
- Get the first sample duration in Segmenter.
- Pass the value all the way to Representation thru MuxerListener.

mp4 code was changed earlier which uses openssl in some way but the
dependency was not updated.
Issue: 15

Due to various libraries' inconsistencies with using EoF, this change
will instead continue to read a file until the number of bytes read is
0. It considers bytes_read == 0 to mean end of file.
Change-Id: I90a592d6ae2b9879fe21bd0c4f9e1c9cbc680afe
Increases the read/write buffers for packager input and output files to
2MB from 256KB, which helps throughput when using network file systems.
Change-Id: Iff5d1b796ba4648f1436e0559c0ca2d353b6c4b5
CreateTemporaryFileInDir uses mkstemp which works only on local files.
This change enables the use of other types of files, like network file
as temporary directory.

If a stream has no language metadata, or has the wrong metadata, this
field allows the user to override this on the command-line.
This also maps all specified languages on the command-line to ISO-639-2
tags as required by the MP4 muxer, so that ISO-639-1 tags specified on
the command-line do not cause a DCHECK to fail.

MSE requires 'base-data-offset-present' not to be set, but FFmpeg may
generate fmp4 files with this flag though it actually uses moof as base.
Log a warning instead of failing directly in this case.
FFmpeg may also generates fmp4 files without tfdt box
(TrackFragmentDecodeTime) box, which is again non-MSE compliant. Handle
this scenario properly.
Bug: 18613712
Also fixes a test failure in SegmentTemplateTest introduced in an earlier
change.

Fix b/18005827 Packager crashes in debug mode with widevine decryption
enabled given a non-existing file.
Fix b/18005632 Packager crashes with invalid fixed_key_encryption
parameters.
Also cleans up some code.
Change-Id: I097f5c8dc113eb6d33b42b19a4bf5de125c47c30
- 17932674 Packager crashes when an incorrect key is provided to wvm.
- 17932293 Packager crashes if no key source is provided for wvm input.
- 17932868 StreamInfo is cast to AudioStreamInfo unconditionally and corrupts memory in wvm_media_parser
- 17932033 input: wvm --enable_fixed_key_decryption Segmentation Fault.

This is a follow up to previous CL.
Generated using command:
find {media,app,mpd} -type f -exec sed -r -i 's/#include "(.*)"/#include
"packager\/\1"/' {} \;
common.gypi and mpd.gyp are also modified to take the path change into
consideration.
