Shaka Packager Versions Save

Added

• Support cue alignment from multiple demuxed streams (#355).

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).

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.
• Support skip_encryption stream descriptor fields (#219).
• Improved documentation and tutorials.

Changed

• Refactored packager code and media pipeline.
• Exposed top level packaging interface.
• Renamed --webm_subsample_encryption flag to --vp9_subsample_encryption flag.
• 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).

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).

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).

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.

Added

• Added a runtime flag to use decoding timestamp 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).

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.

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.
