Raw Blame History

## [2.3.0] - To be released
### Changed
- Disable bundled binutil and gold on Linux by default. There may be a slight
increase in binary link time.
## [2.2.0] - 2018-08-16
### Added
- EditList support in ISO-BMFF in both input and output (#112).
- Multi-DRM support with --protection_systems flag (#245).
- HLS AVERAGE-BANDWIDTH support (#361).
- Dynamic Ad Insertion preconditioning support with Google Ad Manager (#362, #382, #384).
- Configurable UDP receiver buffer size (#411). This can help mitigate or
eliminate packet loss due to receiver buffer overrun.
- Allow non-zero text start time (#416). Needed for live text packaging.
### Changed
- Deprecated --mp4_use_decoding_timestamp_in_timeline.
- Deprecated --num_subsegments_per_sidx.
- Generate DASH IF IOP compliant MPD with mpd_generator by default.
- Adjust timestamps in ISO-BMFF if there is an initial composition offset
as we believe that an EditList is missing in this case (Related to #112).
- Add an adjustable offset to transport streams (MPEG2-TS, HLS Packed Audio)
(Related to #112). The offset is configurable with
--transport_stream_offset_ms. The default is 0.1 seconds.
- Set default --segment_duration to 6 seconds.
- Set default --clear_lead to 5 seconds. Shaka Packager does not support partial encrypted segments,
so if segment_duration is 6 seconds, then only the first segment is in clear, with all the
following segments encrypted.
- Set default --io_block_size to 64K.
- Disable Legacy Widevine HLS signaling for HLS with Widevine protection system by default. Use flag
--enable_legacy_widevine_hls_signaling to enable it if needed.
### Fixed
- Build failures in Windows with CJK environment (#419).
- Segmentation fault when processing WebVTT with out of order cues (#425).
- Support WebVTT cues without payload (#433).
- segmentAlignment is not set correctly in static live profile for multi-period
content (#435). Theoretically it could happen for single period content as
well, but with very low possibility of occuring.
- Segmentation fault when packaging with an empty VTT file (#446).
- Possible file name collision when --temp_dir is used (#448).
### Doc
- Added documentation for PlayReady and FairPlay (#306).
- Added examples for TrickPlay.
- Fixed live HLS example (#403).
- Fixed DockerHub instructions link (#408).
- Added documentation for Dynamic Ad Insertion preconditioning.
- Added instructions for missing curl CA bundle on mac.
## [2.1.1] - 2018-07-03
### Changed
- Warn if HLS type is not set set to LIVE for UDP inputs (#347).
- Use new vp09 codec string for WebM by default (#406). Set command line flag:
`--use_legacy_vp9_codec_string` if the old behavior is needed.
- Allow trailing null bytes in NAL units, to allow contents with the H264 spec
violation to be processed instead of erroring out (#418).
### Fixed
- Fix MPD@duration not set with MPDGenerator (#401). This is a regression
introduced in v2.0.1.
- Remove 'wvtt' in HLS master playlist codec string as it breaks some old Apple
products, e.g. AppleTV3 (#402).
- Fix potential text Segment Timeline not being grouped together in DASH mpd
(#417), which happens when `--allow_approximate_segment_timeline` is set.
## [2.1.0] - 2018-05-22
### Added
- Support Widevine and PlayReady PSSH generation internally in packager (#245).
Documentation will be updated later.
- Support removing segments outside of live window in DASH and HLS (#223).
- Support UTCTiming for DASH (#311).
- Support approximate SegmentTimeline (#330) under flag
--allow_approximate_segment_timeline. The flag is disabled by default and it
will be enabled in a later release.
- Support UDP Source Specific Multicast (SSM) (#332).
- Support elementary audio (Packed Audio) for HLS (#342).
- Support FLAC codec (#345).
- Support AAC with program_config_element (#387).
- Support Widevine entitlement license with dual PSSH.
- Add license notice in --licenses.
### Changed
- Ignore unsupported audio codec in the source content (#395). This allows other
supported streams to be processed and packaged.
### Fixed
- Fix bitrate for DASH on-demand profile too (#376).
- Fix Ad Cues and EXT-X-KEY tag handling in HLS iFrames only playlist
(#378, #396).
- Skip Style and Region Blocks in the source instead of failing (#380).
- Fix potential slice header size off by one byte in H265 (#383).
- Fix potential partial DASH segments during live packaging (#386).
- Fix incorrect BOM used in WEBVTT header (#397).
- Fix TS mimetype in DASH.
## [2.0.3] - 2018-04-23
### Changed
- Removed --pto_adjustment flag (related to #368).
### Fixed
- Use max bitrate in Representation@bandwidth instead of average bitrate (#376).
- Set Widevine key request content-type to JSON instead of xml (#372).
- Fix default_language not working if 2-char code is used (#371).
- Do not force earliest_presentation_time to 0 for VOD (#303).
- Generate more precise time in Period@duration (#368). This avoids possible
rounding error in MSE causing frames to be dropped.
## [2.0.2] - 2018-03-27
### Added
- Support cue alignment from multiple demuxed streams (#355).
## [2.0.1] - 2018-03-05
### Added
- Recognize m4s as a valid extension for init segment (#331). It is used to be
allowed as the extension for media segments only.
- Improve DASH multi-period support: calculate presentationTimeOffset and
Period@duration from video segment presentation timestamps. This avoids
video playback jitters due to gaps.
### Fixed
- Handle invalid WebVTT with start_time == end_time gracefully (#335).
- Ignore invalid `meta` box in mp4 files, which Android's camera app generates
(#319).
- Set stream duration in init segment for mp4 with static live profile (#340).
## [2.0.0] - 2018-02-10
### Added
- Enhanced HLS support.
- Support for attributes RESOLUTION, CHANNELS, AUTOSELECT and DEFAULT.
- Live and Event playlists.
- fMP4 in HLS (including byte range support).
- DRM: Widevine and FairPlay.
- I-Frame playlist.
- Enhanced subtitle support.
- Segmented WebVTT in fMP4.
- Segmented WebVTT in text, for HLS.
- Support generating DASH + HLS manifests simultaneously (#262).
- AC3 / E-AC3 support.
- Experimental multi-period support.
- Raw key multi-key support.
- DASH Trickplay.
- Make fMP4 output CMAF compatible.
- Support for WebM colour element.

- Deprecated --availability_time_offset flag.
### Fixed
- Write manifests atomically to fix possible truncated manifests seen on clients
(#186).
- [WebM] Fix live segmenter overflow if longer than two hours (#233).
- Fix a possible interferenace problem when re-using UDP multicast streams in
different processes (#241).
- Create directories in the output path if not exist (#276).
- Fix order of H265 VPS, SPS, PPS in hvcC box (#297).
- Handle additional unused mdat properly (#298).
- Fix possible incorrect HEVC decoder configuration data (#312).
- Handle varying parameter sets in sample when converting from NAL unit stream
to byte stream (#327).
## [1.6.2] - 2017-04-18
### Added
- Added an option to keep parameter set NAL units (SPS/PPS for H264,
SPS/PPS/VPS for H265), which is necessary if the parameter set NAL units
are varying from frame to frame. The flag is --strip_parameter_set_nalus,
which is true by default. This addresses #206 (the flag needs to be set to
false).
### Fixed
- Fixed the problem that sliding window logic is still active with DASH static
live profile (#218).
- Fixed AAC-HE not correctly signaled in codec string (#225).
- [WebM] Fixed output truncated if using the same file for both input and
output (#210).
- [WebM] Fixed possible integer overflow in stream duration in MPD manifest
(#214).
## [1.6.1] - 2017-02-10
### Changed
- Enable --generate_dash_if_iop_compliant_mpd by default. This moves
ContentProtection element from Representation to AdaptationSet. The feature
can still be disabled by setting the flag to false if needed.
### Fixed
- MPD duration not set for live profile with static mpd (#201).
## [1.6.0] - 2017-01-13
### Added
- Added support for Windows (both 32-bit and 64-bit are supported).
- Added support for live profile with static mpd by setting flag
--generate_static_mpd (#142). This allows on demand content to use segment
template.
- Added support for tagging a specific audio AdaptationSet as the default /
main AdaptationSet with --default_language flag (#155).
- Added UDP options support: udp://ip:port[?options]. Currently three options
are supported: reuse=1|0 whether reusing UDP sockets are allowed (#133),
interface=a.b.c.d interface address, timeout=microseconds for socket timeout.
- Added 4K and 8K encryption support (#163).
### Changed
- [WebM][VP9] Use subsample encryption by default for VP9 per latest WebM spec.
The feature can be disabled by setting --webm_subsample_encryption=false.
- [WebM] Mimic mp4 behavior: either all the samples in a segment are encrypted
or all the samples are clear.
- [WebM] Move index segment forward to right after init segment (#159).
### Fixed
- Fixed AdaptationSet switching signalling when
--generate_dash_if_iop_compliant_mpd is enabled (#156).
- [H.264] Fixed access unit detection problem if there are multiple video slice
NAL units in the same frame (#134).
- [WebVTT] Detect .webvtt as WebVTT files.
- [WebM] Fixed keyframe detection in BlockGroup for encrypted frames.
- [HLS] Fixed HLS playlist problem when clear lead is set to zero (#169).
- Fixed --version command.
### Deprecated
- Deprecated flag --udp_interface_address. Use udp options instead.
- Deprecated flags --single_segment and --profile. They are now derived from
the presence of 'segment_template' in stream descriptors.
## [1.5.1] - 2016-07-25
### Added
- Added a runtime flag to use dts in timeline for mp4:
--mp4_use_decoding_timestamp_in_timeline
### Changed
- Remove restriction that sps:gaps_in_frame_num_value_allowed_flag should be
0 in h264. Packager should not care about this flag (#126).
- Remove restriction that sample duration cannot be zero. A warning message
is printed instead (#127).
### Fixed
- Fix text formats (webvtt, ttml) not recognized problem (#130).
## [1.5.0] - 2016-07-12
### Added
- Added TS (output) and HLS (output) with SAMPLE-AES encryption support.
Note that only H.264 and AAC are supported right now.
- Added support for CENCv3, i.e. 'cbcs', 'cbc1', 'cens' protection schemes.
- Added H.265 support in TS (input) and iso-bmff (input / output).
- Added experimental Opus in iso-bmff support.
### Changed
- Change project name from edash-packager to shaka-packager. Also replaces
various references of edash in the code accordingly.
## [1.4.1] - 2016-06-23
### Fixed
- [VP9] VPCodecConfiguration box should inherit from FullBox instead of Box.
- [VP9] Fixed 'senc' box generation when encrypting mp4:vp9 with superframe.
- [WebM] Close file before trying to get file size, so the file size can be
correctly calculated.
### Changed
- [MP4] Ignore unrecognized mp4 boxes instead of error out.
## [1.4.0] - 2016-04-08
### Added
- Added support for MacOSX (#65). Thanks to @nevil.
- Added support for Dolby AC3 and EAC3 Audio in ISO-BMFF (#64).
- Added support for language code with subtags, e.g. por-BR is now supported.
- Added a new optional flag (--include_common_pssh) to widevine encryption
to include [common system pssh box](https://goo.gl/507mKp) in addition to
widevine pssh box.
- Improved handling of unescaped NAL units in byte stream (#96).
### Changed
- Changed fixed key encryption to generate
[common system pssh box](https://goo.gl/507mKp) by default; overridable by
specifying pssh box(es) explicitly with --pssh flag, which is now optional.
--pssh should be one or more PSSH boxes instead of just pssh data in hex
string format if it is specified.
- Improved subsample encryption algorithm for H.264 and H.265. Now only video
data in slice NALs are encrypted (#40).
### Fixed
- Split AdaptationSets by container and codec in addition to content_type,
language. AVC/MP4 and VP9/WebM are now put in different AdaptationSets if
they are packaged together.
- Fixed index range off-by-1 error in WebM DASH manifest (#99).
- Fixed WebM SeekHeader bug that the positions should be relative to the
Segment payload instead of the start of the file.
## [1.3.1] - 2016-01-22

### Added
- Added 'cenc:default_KID' attribute in ContentProtection element for non-MP4,
i.e. WebM mpd too #69.
- Added WebM content decryption support #72.
### Fixed
- Fixed decoding timestamp always being 0 when trasmuxing from WebM to MP4 #67.
- Improved sample duration computation for WebM content to get rid of possible
gaps due to accumulated errors #68.
- Fixed possible audio sample loss in WebM parser, which could happen if there
are audio blocks before the first video block #71.
## [1.3.0] - 2016-01-15
### Added
