v2.2.0

Added

  • EditList support in ISO-BMFF in both input and output (#112).
  • Improved 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.
