If no hls group name is given, we would default to "audio" but as
we are working to support text, this won't make sense to see
GROUP="audio" on a text stream.
Instead default to "default-audio-group" for audio streams. A specific
text default will be added later.

Instead of using next segment start time, as CueEvent time may not
align with segment start time exactly.
Also remove the incorrect DCHECK in ChunkingHandler when processing
kScte35Event.

Moved muxer listener creation into a factory so that it can be
initialized once and then the factory only needs to be passed
around rather than all the parameters.
Change-Id: Ibf7df66c08debddbe6f6ff8995e7910b9ad17f3f
Changed muxer listener to use "default" instead of {}
when defining its constructor and destructor in its
header file.

This change introduces handlers to output WebVtt text files. There is
only one output but there is a common base to support others.
WebVttOutputHandler which handles all communication with other handlers
and WebVttSegmentedOutputHandler is responsible for listening for events
and choosing when and where to write cues and headers.

Seeing some failures on some platforms when compiled with clang
disabled:
GYP_DEFINES="clang=0" gclient runhooks
Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
direct control: dangling-else, deprecated-declarations,
unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
all linux distributions.

Derive file size from media ranges instead.
Also fix subsegment range reporting for WebM (internal variable,
no output affected).
Change-Id: I5f8152dff4c2cd5fbae5550992b86a669e278f7b
- Use byte range format if segment_template is not set in MediaInfo.
- Change HlsNotifier::NotifyNewSegment() to take start byte offset.
- Change HlsNotifyMuxerListener to cache the segment information if
MuxerOptions::segment_template is set.
Change-Id: Ida1b8b9198acc5c43e3a5d9a641c78c81bc9a6ac
- Changed OnMediaEnd() to take (sub)segment ranges.
- Define a structure to pass the ranges.
- This requires muxers to "cache" the segment ranges but in most cases,
they already do it, e.g. 'sidx' for mp4.
Change-Id: I16b974c1f0f54ca658cc6dbe605efff84a3f52eb
- Remove the TS key rotation not supported check as there is nothing
to be done for key rotation in TS for SAMPLE-AES.
- Fix IV updated problem in new segments even if crypto period does
not change.
- Avoid duplicate EXT-X-KEY tags if it does not change.
- Make EXT-X-DISCONTINUITY-SEQUENCE match with number of removed
EXT-X-DISCONTINUITY.
- Added end to end test for HLS with key rotation.
Change-Id: I73cb82e9f5575fcdf63ee643228efe78e6766302
- This change has the muxer listener side changes.
- Also changed SetContentProtectionFields() to take vector for
default_key_id so that MuxerListener subclasses don't need to convert
it to string.

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.

Also moved MediaHandler output validation to Initialize instead.
This CL also addresses #122 with consistent chunking.
Change-Id: I60c0da6d1b33421d7828bcb827d18899e71884ce
- 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

calling NotifyEncrytionStart().
Fixes#169
Change-Id: I597f317d2ddeb3091b7e9d238eb9695b4cc9c69d
- Add MuxerListener::OnEncryptionStart() for notifying that further
segments are encrypted.

Since the |extra_data| field contains codec-specific configuration
data, it makes sense to call it |codec_config|.
Change-Id: If9e35165a00fe82628cf931df397a8ef06505b0d
- Add hls_name and hls_group_id fields to MuxerOptions. This is used to
pass the NAME and GROUP-ID values for EXT-X-MEDIA tag to
MuxerListener.
- Change MuxerListener::OnEncryptionInfoReady() to take an
initialization vector.
- Change MuxerListener::OnNewSegment() to take segment name.
- Reworded and formatted MuxerListener comments to Doxygen style.

KeySource is now an abstract class that is implemented in two
types WidevineKeySource and FixedKeySource. This also updates
fixed key encryption to use v1 PSSH boxes with the common system
ID.
This also updates the --pssh argument. Now it accepts full PSSH
boxes rather than data. Multiple PSSH boxes can be concatenated
together.

Change-Id: I4bd0290f6d8b965f7d118f075c96e0f267d7e831
* EncryptionKey now contains them rather than a PSSH box.
* Outputs PSSH boxes for each entry.
* Outputs a ContentProtection element for each entry.
* Removed SystemName and UUID from KeySource.
* Removed --scheme_id_uri packager argument.

There is a target name conflict between packager/base/base.gyp:run_all_unittests and
media_test.gyp:run_all_unittests. Change to media_test.gyp:run_tests_with_atexit_manager to
resolve the conflict.
