I am trying to change the selected video track in a multi-angle adaptive HLS playlist as described in Listing 13 here "Variant playlist with 3 different camera angles and different bit rates."

I have created a test stream with 3 different "angles" each having 3 adaptive variants here:

#EXTM3U

#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="3000k",NAME="Red",AUTOSELECT=YES,DEFAULT=YES
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="3000k",NAME="Green",AUTOSELECT=YES,DEFAULT=NO,URI="green/index-f1-v1-a1.m3u8"
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="3000k",NAME="Blue",AUTOSELECT=YES,DEFAULT=NO,URI="blue/index-f1-v1-a1.m3u8"

#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="5000k",NAME="Red",AUTOSELECT=YES,DEFAULT=YES
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="5000k",NAME="Green",AUTOSELECT=YES,DEFAULT=NO,URI="green/index-f2-v1-a1.m3u8"
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="5000k",NAME="Blue",AUTOSELECT=YES,DEFAULT=NO,URI="blue/index-f2-v1-a1.m3u8"

#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="8000k",NAME="Red",AUTOSELECT=YES,DEFAULT=YES
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="8000k",NAME="Green",AUTOSELECT=YES,DEFAULT=NO,URI="green/index-f3-v1-a1.m3u8"
#EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID="8000k",NAME="Blue",AUTOSELECT=YES,DEFAULT=NO,URI="blue/index-f3-v1-a1.m3u8"


#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=613606,RESOLUTION=1920x1080,CODECS="avc1.640028,mp4a.40.2",VIDEO="3000k"
red/index-f1-v1-a1.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=815785,RESOLUTION=1920x1080,CODECS="avc1.640028,mp4a.40.2",VIDEO="5000k"
red/index-f2-v1-a1.m3u8

#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1110022,RESOLUTION=2560x1440,CODECS="avc1.640032,mp4a.40.2",VIDEO="8000k"
red/index-f3-v1-a1.m3u8

Unfortunately I'm not able to determine from the TrackSelector API how I can actually change to a different "angle" as a result of user button press, for instance. Is this possible with ExoPlayer v2.3.0 presently?

Thanks!

is there a way to achieve that in ExoPlayer r2.5.2?

Bumping up to see if this is possible yet in ExoPlayer 2.8.2. Thanks!

Still on the radar but not on the roadmap yet, unfortunately. Thanks for your patience!

Add video and closed caption renditions to HlsMasterPlaylist
65bab95 
Still skipping any renditions that have a null URL, which means that
closedCaptions in particular is always empty. This restriction will
be removed in a subsequent change, which will also remove muxedAudioFormat
and muxedAudioCaptions from HlsMasterPlaylist and instead derive them
from the Variant and Rendition information in HlsMediaPeriod.

Pre-resolve HlsUrl urls
2623b4b 
This is to make it possible to use equality of HlsUrl.url fields
to determine whether two HlsUrls point at the same media playlist.
This doesn't work currently because it's possible to mix absolute
and relative urls, which will not be equal until after the relative
url is resolved against the playlist baseUrl.

Remove HlsUrl and introduce HlsMasterPlaylist.mediaPlaylistUrls
99f8913 
- This removes the need for Variant and Rendition to have a common
  base class, allowing the url field to be marked as @nullable in
  Rendition but not in Variant.
- The addition of mediaPlaylistUrls is needed for the new StreamKey
  indexing for HLS. It's also convenient in a couple of places (e.g.
  HlsDownloader), where a list of all media playlist URLs is needed.
- Lots of places where HlsUrl was passed only needed the actual
  URL (not the Format, which is the other piece of HlsUrl). Passing
  just the URL is a little simpler, and resolves some of the naming
  confusion.
