CHANGELOG.md

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 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.

1.3.1 - 2016-01-22

This release fixes and improves WebM parsing and packaging.

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

• Added support for new container format: WebM.
• Added support for new codecs:
  • H265 in ISO-BMFF (H265 in other containers will be added later).
  • VP8, VP9 in WebM and ISO-BMFF (experimental).
  • Opus and Vorbis in WebM.
  • DTS in ISO-BMFF.
• Added Verbose logging through --v or --vmodule command line flags.
• Added Subtitle support for On-Demand: allowing subtitle inputs in webvtt or ttml. Support for subtitle inputs in media files will be added later.
• Added version information in generated outputs.

Changed

• Store Sample Auxiliary Information in Sample Encryption Information ('senc') box instead of inside Media Data ('mdat') box.
• Got rid of svn dependencies, now all dependencies are in git repo.
• Switched to boringssl, replacing openssl.

Fixed (in addition to fix in 1.2.1)

• Fixed issue #55 DASH validation (conformance check) problems.
• Fixed AssetId overflow in classic WVM decryption when AssetId exceeds 0x8000000.
• Fixed a memory leak due to thread object tracking #61.

1.2.1 - 2015-11-18

Fixed

• Improved support for WVM files:
  • Support files with no PES stream ID metadata.
  • Support files with multiple audio or video configurations.
• Fixed a race condition when flushing ThreadedIoFile which may cause flush to be called before file being written; fixed another race condition in ThreadedIoFile if there is an error in reading or writing files.
• Relaxed requirement on reserved bits when parsing AVCC #44
• Fixed stropts.h not found issue in CentOS 7.

1.2.0 - 2015-10-01

Added

Changed

• Improved performance with threaded I/O.
• Disabled gold linker by default, which does not work on Ubuntu 64bit server.
• 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;

  • Added cenc:default_KID and cenc:pssh to ContentProtection elements;
  • Moved ContentProtection elements up to AdaptationSet element, controlled by --generate_dash_if_iop_compliant_mpd;
  • Moved representations encrypted with different keys to different adaptation sets, grouped by @group attribute, controlled by --generate_dash_if_iop_compliant_mpd.
• Fixed SSL CA cert issue on CentOS.
• Fixed a couple of packager crashes on invalid inputs.
• Read enough bytes before detecting container type. This fixed MPEG-TS not recognized issue on some systems.
• Generate proper tkhd.width and tkhd.height with non-square pixels.
• Support composition offset greater than (1<<31).
• Fixed one-sample fragment issue with generated audio streams.
• Fixed and correct width/height in VisualSampleEntry for streams with cropping. This fixes encrypted live playback issue for some resolutions.
