2.4.0 - 2019-12-26

Added

  • Support hardware accelerated AES (#198).
  • Support various HDR formats for HEVC (#341, #632).
  • Add more loggings for GAPs (#474).
  • Retry file deletion if it fails (#533). Only applicable to live packaging.

  • Support PlayReady PSSH generation with CBCS protection scheme (#602).
  • [HLS] Generate FRAME-RATE attribute in EXT-X-STREAM-INF tag (#634).
  • Add --quiet to suppress LOG(INFO) outputs (#661).

Fixed

  • Handle large descriptor header size in 'esds' box (#536).
  • Improve the handling of corrupted timestamp in live streams (#563).
  • Fix problems that target duration is not set in mpd/hls params, which then results incorrect bandwidth estimates (#498, #581).
  • Allow absolute path in playlist name (#585).
  • [HLS] Fix possible zero bandwidth for EXT-I-FRAME-STREAM-INF (#610).
  • Supports encryption of streams with parameter sets in frames, i.e. avc3, hvc1 etc (#621, #627).

2.3.0 - 2018-12-20

Added

  • Alpine Linux support (#164).
  • WebVTT style and region support (#344).
  • Marlin DRM support (#381).
  • HLS CHARACTERISTICS attribute on #EXT-X-MEDIA (#404).
  • Default text language support ('--default_text_language') (#430).
  • AV1 support (#453).
  • HLS audio only master playlist support (#461).

Fixed

  • MPEG-TS demuxing with AC-3 / E-AC-3 (#487). kFrameSizeCodeTable were reversed results in wrong frame size being detected except for 44.1kHz.
  • HLS peak bandwidth calculation with very short segments (#498). The short segments should be excluded from peak bandwidth calculation per HLS specification.
  • Output directory permission (#499). The new directory permission was fixed to 0700.
  • Workaround access units with extra AUD (#526). VLC inserts an extra AUD in the key frames, which caused packager to delay emitting the frame. The delays accumulated and became noticeable after running the live packaging for some time.
  • Problem when using Trick Play with Ad Cues (#528).

Changed

  • Disable bundled binutil and gold on Linux by default. There may be a slight increase in binary link time.
  • Reduced official Docker image size from ~1GB to ~15MB (#535). The new image is based on Alpine and contains only result binaries (packager and mpd_generator).

2.2.1 - 2018-09-20

Added

  • Added support for seek preroll in AAC and other audio codecs (#452). This also addressed 'Unexpected seek preroll for codecs ...' warnings.
  • Computes and sets VP9 Level in the codec config if it is not already set (#469). This fixed VP9 in ISO-BMFF files generated by FFmpeg v4.0.2 or earlier which does not have level set in the codec config.

Fixed

  • Added a workaround for TS contents with dts moving backwards (#451). So instead of generating a sample with negative duration, which ExoPlayer does not handle, use an arbitrarily short duration instead.
  • Fixed pattern signaling in seig for key rotation with cbcs (#460).
  • Fixed incorrect segment name with $Time$ in segment_template (#472). This resulted in the first segment being overwritten and led to playback problems.
  • Fixed TTML text input passthrough in DASH (#478). This is a regression introduced in v2.2.0.

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.

  • 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).

  • 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).

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 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 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.

  • Delete temperary files created by packager when done.
  • Updated MediaInfo file formats.

Fixed

  • Support ISO-BMFF files with trailing 'moov' boxes.
  • DASH-IF IOP 3.0 Compliance. Some changes are controlled by flag --generate_dash_if_iop_compliant_mpd. It is defaulted to false, due to lack of player support. Will change the default to true in future releases.
    • Added @contentType to AdaptationSet;
    • For video adaptation sets, added @maxWidth/@width, @maxHeight/@height, @maxFrameRate/@frameRate and @par attributes;
    • For video representations, added @frameRate and @sar attributes;
    • For audio adaptation sets, added @lang attribute;
    • For representations with aligned segments/subsegments, added attribute @subSegmentAlignment/@segmentAlignment;
