- Another minor change in segmenter_test_base: scoped_refptr can
be passed by value, remove ".Pass".

* 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.

Javascript/JSON does not support int64_t or unsigned numbers. asset_id,
if greater than 0x80000000 will be converted to negative number. Use
double to represent asset_id instead as 32-bit integer can be lossless
represented using double.

- Replaced urn:mpeg:DASH:schema:MPD:2011 with
urn:mpeg:dash:schema:mpd:2011. The former is from the old spec.
- Replaced the MPD schema with the latest one.
- Fixed subSegmentAlignment typo with subsegmentAlignment.

This can be used for unit tests to reduce the need for temporary
files. A MemoryFile acts the same as any other File object, but
stores the contents in memory. The memory pointer can be accessed
directly. A file with the 'memory://' prefix will be a memory file.

- 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

Profiling can be enabled by setting profiling=1 in gyp, e.g.
GYP_DEFINES="profiling=1" gclient runhooks
To turn on heap profiling, use the HEAPPROFILE environment variable
to specify a filename for the heap profile dump, e.g.
HEAPPROFILE=/tmp/heapprofile out/Release/packager ...
To turn on cpu profiling, use the CPUPROFILE environment variable
to specify a filename for the cpu profile dump, e.g.
CPUPROFILE=/tmp/cpuprofile out/Release/packager ...
Note that profiling may not work for debug builds, so use release
build if possible.
See docs/linux_profiling.md for details.
This change will help identify and resolve problem behind Issue #61.

- 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 two stream descriptors that are both used to tell the output
format. If it is not given, the packager will use the output file
extension to determine the output format.
Change-Id: Ib8d5dcf52956c2d451e77ea6a90d9502d4a77064
* Added WebM muxer that supports both single and multi-segment modes.
* WebM muxer supports MPD generation.
* Enabled WebM muxer and demuxer in packager.

- Also set --clear_lead to 1 if encryption is enabled to make sure some
of the segments are encrypted.
- Also fixed glint errors.
Change-Id: Ie92ad3ea1a3fd95d059e424a114b863ac393e6bf
- Check whether if it can be parsed by libxml2 and check if the root
element is a 'tt' element.
- Added unit tests for determining TTML and WebVTT.
Change-Id: I4fea1881f0ab70970700601d8d7cea32cc04752c
- Since most use cases use notifier implementations that already uses
locks, removing locks from MpdBuilder.
- Added locks to MpdNotifier::Flush() implementations. Multiple threads
were able to write to the same file.
Issue #45, #49
Change-Id: I6e39824485672f40e6c947da97f1743fac174167
- Added ignores.txt file. When doing a tsan build,
tsan_blacklist gyp flag should point to the file.
Change-Id: Ia69f89f1906f0b386e081a7df5a7c867e411f8fd
Also update the code to generate CompressorName in VideoSampleEntry
for both AVC1 and various VP codecs.
Change-Id: I2355f8008a72806e852aa1ec6c80e9141b97d963
- Added factory methods for creating Representation and AdaptationSet in
tests.
- Since most tests only needed access to the constructors for
Representation and AdaptationSet, instead of using
FRIEND_TEST_ALL_PREFIXES() for each test case, added factory methods
on the test class.
- Check the 'frameRate' attribute in
CommonMpbBuilderTest.SetSampleDuration.

Uses EXPECT_NEAR for comparison with an acceptable error bound. Also
increases error bound to 50ms.
Change-Id: I8fc61b3b915a50f8fe33b9ea72e123aefee25a80
- 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.
Change-Id: I1f34d303ae1f3ea81820e3368ab66b8420498372
- Added --iv to inject iv for fixed key encryption.
- Added support for key rotation in fixed key encryption.
- Added --use_fake_clock_for_muxer to set timestamp to 0 in the output.
Also updates stream info dump message:
- Modified pixel_width: %d\n pixel_height: %d to pixel aspect ratio: %d:%d
- Removed language from video stream info.
These flags should only be used for testing.
Change-Id: Iedf8d6d6492226219f49fe44d932645f557010e4
- ContentProtection elements were missing when using MpdWriter,
therefore mpd_generator also did not generate ContentProtection.
- MpdWriter uses MpdNotifier now, instead of directly using MpdBuiler.
- Add mock_mpd_notifier.{h,cc} to be shared by several tests.

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
Change-Id: Id55c5acf245bee3f4e66302b2042eb7d9c488c19
- Because MpdBuilder no longer sets ContentProtection, live was broken.
- For key-rotation, <cenc:pssh> element is updated.
Change-Id: I45bb80a12faff39ccf5deb82439c0732ed9cea59
- Without the Flush() method the implementation had to do writes in
almost all methods. Usually the user of the notifier knows when to
write out the MPD.
Change-Id: Ic165d4594f01357a8ac7e8501eefa0f85c08d32f
- SimpleMpdNotifier didn't register the container ID to its map for VOD.
- AddContentProtection() was not implemented.

Quotient reduction to minimal form does not work well in practice due to
rounding of the inputs.
Bug: 23432995
Change-Id: If333ab48accb7f6a3fac6ba4eb48ca7b9cee9826
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
- subSegmentAlignment logic assumed that all Representations were
added before calling Representations::AddNewSegment() on any
Representation in an AdaptationSet. It is not a valid assumption
for VOD and is removed.
Change-Id: Ifb7e34ee103ee30027e45a804427baf281f3137c
- 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.
Change-Id: Iedbe6a44465aac6723b6ea2de30aed180821eccd
- Call NotifyNewSegment() in MpdNotifyMuxerListener::OnMediaEnd() to
notify subsegments.
- This is necessary for MpdBuilder to calculate subsegmentAlignment.
Change-Id: I9359c408da4f616e543a6d9e568b010a90c90185
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
- Saves sample_duration in the media_info protobuf.
- When MpdNotifyMuxerListener::OnMediaEnd() is called, media_info passed
to MpdNotifier::NotifyNewContainer() should contain the sample
duration.
- Add tests for MpdNotifyMuxerListener.
- Moved common code from vod_media_info_dump_muxer_listener_unittest.cc
and mpd_notify_muxer_listener_unittest.cc to
muxer_listener_test_helper.cc.
Change-Id: Ibf2340076d45828d26f1af54a1ed8e95e5884c23
- AdaptationSet::OnNewSegmentForRepresentation() calculates whether the
Representations are aligned by looking at the start time and duration.
(Except that duration is not used in this implementation).
- Add RepresentationStateChangeListener to callback
AdaptationSet::OnNewSegmentForRepresentation() from Representation.
Change-Id: I3c30bd6652880dabb9d5c619d8a733ffc789eec9
- The tests couldn't run in parallel using gtest-parallel
(https://github.com/google/gtest-parallel) because all the tests
used the same file.
Change-Id: I9a3d2c20c290fbf4bee2a1d79c4ce9bf802aefcf
- ContentProtection elements should be added explicitly by the
AddContentProtection() methods.
- This is because some MPDs should have ContentProtection at
AdaptationSet level instead of Representation.
- Change SimpleMpdNotifier, which uses MpdBuilder, to add
ContentProtectionElements. The logic is moved from MuxerListener.
- Add Element class for specifying subelements for
ContentProtectionElement.
Change-Id: I9bedfb3e5a5ac0b3d5c702f1e6e4a8608c978d1d
- 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
- Pass pixel_height and pixel_width from VideoStreamInfo to MediaInfo.
- par can only be set if all the Representations have the same
picture aspect ratio. That is the ratio of sar_x*width:sar_y*height
should all be the same.
- If there is a Representation that does not have the sar attribute set,
par is also not set.
