This also changes the callbacks a bit to (a) avoid passing references
for already ref-counted types, and (b) don't pass PID since the
parent knows this and gives it to the child parser.

This adds a new path when parsing MPEG2-TS streams to ignore unsupported
streams. This allows extracting supported streams when some of the
streams are unsupported. For example, you can extract audio from a
file that has unsupported video.

Now text-based WebVTT also uses the generic media pipeline. This
converts the WebVttTextOutputHandler to a WebVttMuxer to be more
consistent with the other muxer types.
This also allows choosing between single-segment text and multi-segment.
Before, we would generate both and use single-segment for DASH and
multi-segment for HLS; but now you can choose between either and either
are supported in both DASH and HLS.

In addition to the MediaSample handling of the MediaParser, this now
adds callbacks for TextSample. This allows reading text streams from
the media files.

- Parse and extract transfer_characteristics from H264/H265 VUI
parameters.
- Set VIDEO-RANGE attribute in HLS according to HLS specification:
https://tools.ietf.org/html/draft-pantos-hls-rfc8216bis-02#section-4.4.4.2
- Also added an end to end test.
Fixes#632.

Latest version of FFmpeg encodes non standard channel layout, e.g. 5.1(side), in AAC using PCE.
This is now supported with the below changes:
- Allow channel_configuration in ADTS header to be 0, as the cctual channel layout is specified
in PCE.
- Add GetFrameSizeWithoutParsing to determine the frame size before actually parsing the frame.
- Skip and resume later if not the whole frame is available.
- Also ensure that the next frame starts with a proper sync word.
Fixes#598.
VLC seems to generate access units with extra AUDs. In #526, the below
sequence is seen:
AUD | SPS | PPS | SPS | PPS | AUD | SEI | SEI | SEI | IDR_SLICE
Previously we exit early when seeing AUD, which results in delayed
processing of the access unit.
The behavior is changed to continue processing the following NAL units
to workaround the content issue.
Closes#526.

kFrameSizeCodeTable rows are ordered by 32kHz, 44.1kHz and 48kHz,
which is the reverse of fscod (48kHz, 44.1kHz and 32kHz).
Also updated unittests.
Fixes#487.

Negative duration is not allowed, so set the duration of that sample to
an arbitrary small value in case it is needed to decode future samples.

Configurable with --transport_stream_offset_ms.
This is needed to compensate for possible negative timestamps in
inputs, which could happen on ISO-BMFF with EditLists.

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.

The error is logged only once to avoid log spamming.
Added definitions for the unsupported stream types for easy look up.

Implemented E-AC3 MPEG-2 Stream Encryption Format for HTTP Live
Streaming specified in https://goo.gl/1sgcwY
Issue #279
Change-Id: I36c1a05e3d0529ff810eaf52bdca45414baa93eb
Audio samples per frame for AC3 was not specified correctly earlier.
Also the number of channels is not correct if LFE channel is on.

Implemented MPEG-2 Stream Encryption Format for HTTP Live Streaming

This change also moved ProgramMapTableWriter creation from TsWriter
to TsSegment.

In prep for changes to Trick Play, we want to make all messages
copy on write so that if the same message is sent to multiple
handlers, it is not possible for one handler to change the data
another handler is using.

Derive file size from media ranges instead.
Also fix subsegment range reporting for WebM (internal variable,
no output affected).
Change-Id: I5f8152dff4c2cd5fbae5550992b86a669e278f7b
- 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.

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.
