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).

- Because MpdBuilder no longer sets ContentProtection, live was broken.
- For key-rotation, <cenc:pssh> element is updated.

- 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.

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.

- 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.

- Call NotifyNewSegment() in MpdNotifyMuxerListener::OnMediaEnd() to
notify subsegments.
- This is necessary for MpdBuilder to calculate subsegmentAlignment.

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.

- The tests couldn't run in parallel using gtest-parallel
(https://github.com/google/gtest-parallel) because all the tests
used the same file.

- 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.

- 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.

- 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.
Change-Id: Id34c95e4a99da9ce028a9f35737cfe5bca9e5697
- 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.

- 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.

BoringSSL removes the variants that had been used, in which the hash
is given a default value. This change makes the code more compatible
with BoringSSL.

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

The input source may produce inputs with very small sizes. Demuxer
needs to accumulate enough bytes before trying to detect the container
type.

Change-Id: Ie25339832a826e78f39b3b25abb98c1ad89e3021
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.

Increases the read/write buffers for packager input and output files to
2MB from 256KB, which helps throughput when using network file systems.

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.
