Release notes version 1.7.*¶
Version 1.7.28 (2017-04-24) - GA¶
- origin: when creating WebVTT from TTML we now collapse "p" elements that have the same timing information into a single cue. (#1894).
- origin: media that is indexed by either a TrackFragmentRandomAccessBox ("tfra") or SegmentIndexBox ("sidx") overrides timing information in the media segment. (#1896).
- dash: added cea-608 signalling through Accessibility element (#1448).
- dash: removed @minWidth and @minHeight attributes. It is unclear what the units are and they are not really relevant.
- dash: added support for live stream events (--archiving=1 --dvr_window_length=0)
- dash: added end-of-stream inband event message to the last media segment (live stream events only).
Version 1.7.27 (2017-03-20)¶
We have made many improvements for DASH (see below), so please verify that your player is working as expected.
- dash: added live time signalling urn:mpeg:dash:utc:http-iso:2014. (#1447)
- dash: compare Representation timelines and only move them to the AdaptationSet when they are identical. This makes it easier to spot GOP alignment errors.
- dash: do not output empty AdaptationSets (e.g. empty subtitles).

- dash: the propagating of query parameters has changed. Query parameters passed in the MPD URL are now added as an EssentialProperty with UrlQueryInfo (at the MPD level) and it is up to the player to add them to the Media Segment URLs (new since ISO/IEC 23009-1:2016).
- packager: added --use_dref_no_subs. (#1444)

- origin: added extended EXT-X-KEY statement in m3u playlists for Marlin (Marlin DRM, #663)
- capture: try harder when configuring the encoder. The Intel Media SDK returns an error instead of a warning on some SDK versions. In the case of a warning or error we now continue trying more settings.

- libfmp4: avoid the loading of all the samples when scanning for embedded captions. Only scan the first AVC sample for SEI message.
- libfmp4: option to combine multiple reads (maxRanges) into a single GET request. currently maxRanges is set to 1 since S3 doesn't support multiple ranges.
- origin: added ingest of VOD HLS. See the specific documentation for the Using HTTP Live Streaming (HLS) as source requirements.

Note that you will need the package_iis policy as well as the option --progressive_playout. This is only available in Apache since it uses "Transfer-Encoding: Chunked" and also requires a HTTP 1.1 client. HTTP Range requests are not supported. When a range is requested the reponse is a 200 and the complete file is returned.
- hls: added playready-envelope encryption.
- dash: added --mpd.profile option for specifying the URN of the "Interoperability Point"
- hls: tightly pack keyframes in MPEG TS. This fixes the BYTERANGE sometimes being off by the size of a TS packet.
- hds: do not use @alternate attribute in version 2 manifests when the audio is the "primary rendition".
- live: fixed purging for archive_segment_length/dvr_window_length greater than 429 seconds in combination of a large timescale (10.000.000).
- libfmp4: added support for "ttml" in "stsd" as output by Carcon Coder.
- hls/hds: added support for "avc3".
- hds: OSMF 2.0 based players crash/stop-responding when SCRIPTDATA is present in the alternate audio track. Do not add onFI messages in alternate audio fragments.

- package-mpd: added Widevine ("cenc" encryption, plus Widevine signaling).
- origin: fixed the one sample missing in each audio fragment bug. This happened when using MP4 as source and Smooth Streaming as playout due to a rounding error caused by different source and destination timescales. A possible workaround is to use the option --iss.minimum_fragment_length=N and set N to the GOP duration.
Version 1.7.1 (2014-07-04)¶
- origin: added Irdeto SKE DRM support for HLS playout (Irdeto Control API, #449)

- hls: updated ID3 Tags to use sps_rbsp and sei_rbsp
- mp4split: Changed console output from stdout to stderr (DEBUG build only).
- Fixed #518 (purging audio timestamps from db). This occured when multiple tracs were posted as a single stream. A possible work-around is to publish audio/video streams separately to the publishing point.
- libfmp4: moved Smooth Streaming client manifest reader into library.
- mp4split: Lowered memory requirements when packaging encrypted content.
- corrected writing of relative URLs with a ":" in the first segment.
- mp4split: added pdin/bloc/ainf/meta/trik boxes for CFF.

- hls: signal version 2 protocol when IV is used.
