|
* and period-change for playbin3
|
|
*
|
|
* NOTE: During bitrate switching in DASH, track-id might be changed
|
|
* NOTE: stream change with new stream-start to qtdemux is playbin3 specific behaviour,
|
|
* because playbin configures new demux per period and existing demux never ever get
|
|
* new stream-start again.
|
|
*
|
|
* Testing step
|
|
* [GROUP 1]
|
|
* - Push events stream-start and segment to qtdemux
|
|
* - Push init and media data to qtdemux
|
|
* [GROUP 2]
|
|
* - Push different (track-id change) init and media data to qtdemux
|
|
* without new downstream sticky events to qtdemux
|
|
* [GROUP 3]
|
|
* - Push events stream-start and segment to qtdemux again
|
|
* - Push the init and media data which are the same as GROUP 2
|
|
* [GROUP 4]
|
|
* - Push events stream-start and segment to qtdemux again
|
|
* - Push different (track-id change) init and media data to qtdemux
|
|
*
|
|
* Expected behaviour
|
|
* - Demux exposes srcpad four times, per test GROUP, regardless of track-id change
|
|
* - Whenever exposing new pads, downstream sticky events should be detected
|
|
* at demux srcpad
