  • packager: added support for converting (basic) WebVTT to dfxp.
  • libfmp4: fixed bug when creating HLS V4 video only playlist. Work-around is to use --hls.no_audio_only.

Version 1.7.2 (2014-11-25)

  • 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.
  • origin: added new playout format --hls.playout=SAMPLE_AES_STREAMINGKEYDELIVERY. This adds signaling for the KEYFORMAT="com.apple.streamingkeydelivery" to the m3u8 playlist.
  • 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.
  • packager: added support for writing "dref"-ed fragmented MP4.
  • origin: added support for reading "dref"-ed fragmented MP4.

  • origin: fixed PES size of metadata stream.
  • mp4split: added key=KID:CEK option.
  • origin: added progressive download of fragmented MP4 (.ismv), also known as Download to own, from a server manifest. 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-hls: calculate the BANDWIDTH for iframe-index playlists using the duration of the media segment. This makes sure that the BANDWIDTH in the iframe-index is never larger than the one specified in the prog-index.
  • 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)
  • package-hls: skip consecutive I-frames when generating the iframe playlist.
  • use "cenc" instead of "piff" in "schm" box (except for "isml"/"piff" brands).
  • package-hls: added EXT-X-INDEPENDENT-SEGMENTS
  • capture: 404/412 status codes now return exit failure after retrying 3 times.
  • mp4split: added support for specifying fractions (numerator / denominator) for minimum_fragment_length options. For example you can now exacly specify 29.97002997 by using 30000/1001.
  • capture: updated to Media SDK 2014 R2
  • package-hls: made ID3 tags compatible.
  • package-hls: added --encrypt-iv to specify IV.

  • cff: removed "free" box (used for padding) after "ftyp".
  • added Conax Contego HLS encryption with PlayReady DRM. (--conax.key_id, --conax.content_key, --conax.license_server_url, --conax.key_iv=<8 BYTES, NONCE ONLY!>).

Version 1.7.0 (2014-05-15)

  • 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.
  • mp4split: set duration in mvhd box (as well as mehd box) for PIFF compatibility.
  • Added hashing to IV when creating a fragmented-MP4 file and dynamic playout of smooth/dash fragments.
  • Do not try and update live server manifest files when they are missing meta-data. This may happen with live streams pushed by FFmpeg using -vcodec copy. The @systemBitrate attribute is zero in that case.
  • hls: signal version 2 protocol when IV is used.
