segment-time-mapping event
update contrib-media-sources to 4.6.0
prioritize user enabled playlists over blacklist #1269
never allow playlist selector to select a playlist that has been permanently blacklisted due to incompatible configuration
When filtering playlists within the playlist selectors, if there are no enabled playlists (i.e. not blacklisted internally AND not disabled by the user) available, then fall back to using the list of playlists not disabled by the user regardless of blacklist state.
make sure playlists blacklisted from an illegal media switch is permanently blacklisted, as there is no reason to try it again at a later time.
The representation api will return a list that filters out just incompatible playlists instead of both incompatible playlists and temporary blacklisted playlists.

Use a starting bandwidth value of 0.0625 MB/s on Android devices
Do not allow an up-switch in quality until a certain amount of forward buffer has been filled, BUFFER_LOW_WATER_LINE
Dynamically increase the BUFFER_LOW_WATER_LINE and GOAL_BUFFER_LENGTH from 0 - > 30 and 30 -> 60 respectively during the first 30 seconds of playback
Abort segment requests before completion if bandwidth reported by the XHR progress event shows that network conditions are not fast enough to complete the request without causing rebuffering
5.7.0 (2017-06-27)
update mux.js to 4.1.5 and videojs-contrib-media-sources to 4.4.6 #1180
Only flush PES packets from TS parsing front end when they are complete
Complete is defined as any time PES_packet_length matches the data’s length OR is a video packets
Works around an issue with incomplete packets getting sent down the pipeline when the source has audio PES packets split between segments
Usage tracking events are fired when we detect a certain HLS feature, encoding setting, or API is used. Note that although these usage events are listed in the README, they may change at any time without a major version change.
For QoS measurement purposes, it may be useful to know how often the playback watcher is activating. Add new events for when the player falls off the back of the live window or stalls due to a video buffer gap.
5.1.0 (2017-01-31)
Updated videojs-contrib-media-sources to v4.2.0
Added support for inserting silence when appending a new segment will introduce a gap in the audio SourceBuffer

Fix qualityLevels setup for videos with a source element #979
If the segment request triggers progress events (that is, XHR2 is supported), bubble those up to the tech. This makes it clearer that buffering is happening even on very slow connections.
Use webcrypto for aes-cbc segment decryption when supported #4
