- Implemented according to v1.0 spec @ https://www.webmproject.org/vp9/mp4/
- v0 is no longer supported
Change-Id: I189c813d788400beda797eea7da943a83dfa7d79
- Added flag --mp4_include_pssh_in_stream, default to true. If it is
set to false, the encrypted mp4 stream will not include pssh.
- Align BytesOfProtectedData to multiple of 16 bytes for cenc.
- Set TrackHeader flag to kTrackEnabled | kTrackInMovie |
kTrackInPreview
- Move mvex to after trak, required by HLS
- Add cmfc/cmfs compatible brands except for avc3/hev1, where CMAF
requires single initialization switching set which is not supported.
- Set duration to 0 in tkhd, mdhd, mvhd.
Also updated major_brand and compatible brands:
- Set major_brand to isom (iso-bmff media file format) and made dash
a compatible brand
- Replaced compatible brand iso6 with iso8 since we use sthd for text
tracks

- Also fix the misleading error if an invalid input is provided
The command line app now correctly reports that the file is not
found instead of stream not available.

This is what webm_subsample_encryption flag actually does.
- Fixes the flag not working problem introduced by previous CLs.
- Also mark flag webm_subsample_encryption as deprecated.
Closes#220

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

- Add EXT-X-MAP tag for init segment.
- Do not set output field on stream descriptor if not specified on
command line. If it's set (internally) then it gets copied to
MediaInfo that gets passed to the manifest generators.

- Disable subsample encryption for VP8 in ISO-BMFF
- Apply block alignment to all subsamples for VP9 in ISO-BMFF,
instead of just superframes.
Change-Id: I8dd31cc16e87abc4d538330eaff9acb0509497df
Also moved MediaHandler output validation to Initialize instead.
This CL also addresses #122 with consistent chunking.

Before this, HLS output did not contain language information.
Now, media playlists are properly tagged with a language in the
master playlist.

Some of the changes are temporary to get the integration going.

This will move ContentProtection element from Representation
to AdaptationSet.
Shaka Player already supports AdaptationSet switching
urn:mpeg:dash:adaptation-set-switching:2016;
ExoPlayer does not support it yet. Filed
https://github.com/google/ExoPlayer/issues/2431 to track the issue.
(ExoPlayer does not like having ContentProtection in Representation
anyway)
Closes b/34691105
Change-Id: I69d0a4d0e15a912a35c8b2686620419a28e4cc99
- Deprecated command line flags --profile and --single_segment.
'segment_template' in stream descriptors implies live profile
and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
static mpd for live profile; if not set, dynamic mpd will be
generated.
Close#142
Change-Id: I78879297ed118f0f246c4753a16ad125bd6b5e4f
- Added two new fields in MpdOptions: dash_profile and mpd_type
- Updated MpdBuilder to support LiveProfile with static mpd
- Command line arguments will be updated in the next CL

Change-Id: Ibd35e5c9e1b1ef98043392e3f04a0af4700135c1
Current mechanism of using AdaptationSet @group is not spec compliant.
The spec compliant mechanism is to use supplemental descriptor with
schemeIdUri: urn:mpeg:dash:adaptation-set-switching:2016 as specified
in ISO/IEC 23009-1:2014/Amd.4:2016.

Three options are supported right now:
- reuse=1|0
Allow or disallow reusing UDP sockets. Default 0.
- interface=a.b.c.d
Address of the interface over which to receive UDP multicast
streams.
- timeout=microseconds
Timeout in microseconds. Default to unlimited.
A UDP url should be of the form udp://ip:port[?options], here
is an example:
udp://224.1.2.30:88?reuse=1&interface=10.11.12.13&timeout=12345
Also deprecate --udp_interface_address flag in favor udp options.

Cues used to be generated in the end of the file; if http range
request is not supported, clients have to download the whole
file to get to the cues.
This CL updated TwoPassSingleSegmentSegmenter to write cues
after writing webm header.
This CL also updates libwebm dependency to latest.
Closes#159

Setting this flag will tag any matching tracks with kRoleMain.
The player will then know which tracks should be default when there
is not a language match.

Language tags can have subtags, such as "por-BR". While the base tag
should be 3 characters, the entire tag can be longer. Rather than
parse out the base tag and check that it is size 3 without the subtag,
we can just trust the ISO tag converter to do the right thing.

- 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.

1. Replace STLDeleter with unique_ptr in container, which is
supported in C++11
2. Replace string_as_array with &string[0] which is guaranteed
to work in C++11

The current behavior of logging to a file in the same directory
as the binary will break if the binary does not have write access
to that directory.
Fixes Issue #139
Change-Id: I11adfaec676fc9bbef2a5caa3261889d1fba3b88
Mimic iso-bmff behavior: either all the samples in a segment are encrypted
or all the samples are clear.

The right way to detect the presence of a keyframe in a BlockGroup
is to look for the absence of the ReferenceBlock element [1].

Also updated packager_test not to fill in output_format by default,
which will help catch these kinds of bugs.
Closes#130

This flag is needed to workaround the Chromium bug

- Try to determine container name from segment_template if output is
not specified
- segment_template descriptor is required for TS
- output descriptor should not be specified for TS
- Generate hls_playlist_name from stream number if not specified
- Update packager_test.py to include playlist validation

Change-Id: Ide7169f1c26c85a6e38272dda0e1af77135b4d90
- Add flags and stream descriptor fields for HLS.
- Remove fields from MuxerOptions. Instead pass them directly to
HlsNotifyMuxerListener.
- Rebase segment names to the master playlist's path where it makes
sense.
Change-Id: If4f54bc56ff46dc6140859a79ed66f7b99112ed7
- Tracks other than video are protected using whole-block full-sample
encryption as specified in ISO/IEC 23001-7:2016(E) 9.7, which is
equivalent to a pattern of 1:0. This is different to the non pattern
encryption counterparts.
- Also updated the code to allow the existence of other protection
schemes in the original content, which will simply be ignored.
- The internal cryptor used by AesPatternCryptor should not use
constant iv, add a DCHECK for that.
- Optimize AesPatternCryptor handling on the special pattern 1:0.
