7.1 KiB
Raw Blame History

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

  • Fixed a deadlock in MpdBuilder which could lead to program hang #45
  • Fixed a race condition in MpdNotifier which could lead to corrupted mpd #49
  • 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

  • Added docker support. Thanks @leandromoreira.

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;
    • For representations with aligned segments/subsegments, added attribute @subSegmentAlignment/@segmentAlignment;
    • 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.

1.1.0 - 2014-10-14

Added

  • Added timeout support for encryption key request.
  • Support mpd generation in packager driver program.
  • Support segment template identifier Time.
  • Support configurable policy in Widevine encryption key request.
  • Support key rotation, with configurable crypto_period_duration.
  • Support UDP unicast/multicast capture.
  • Support auto-determination of SD/HD track based on a configurable flag --max_sd_pixels.
  • Support new input formats:
    • WVM (legacy Widevine format), both encrypted and clear;
    • CENC encrypted ISO-BMFF.

Changed

  • Replaced HappyHttp with curl for http request. Added https support.
  • Changed packager driver program to be able to package multiple streams.
  • Move source code into packager directory, to make it easier to third_party integration.

Fixed

  • Support 64 bit mdat box size.
  • Support on 32-bit OS.

1.0.0 - 2014-04-21

  • Repo management with gclient from Chromium.
  • Support input formats: fragmented and non-fragmented ISO-BMFF.
  • Support encryption with Widevine license server.
  • Support encryption with user supplied encryption keys.
  • Added packager driver program.
  • Added mpd_generator driver program to generate mpd file from packager generated intermediate files.
