Description Alicia Boya García 2021-09-27 07:07:05 PDT
The existing code in
was not checking if the track already existing, creating and
immediately destroying a MediaSourceTrackGStreamer, which then crashed
on an assertion (ASSERTION FAILED: m_isRemoved).

This fixes the following two tests which were crashing with the former
assertion when running in Debug:

- media/media-source/media-mp4-h264-partial-abort.html
- media/media-source/media-source-abort-resets-parser.html

Doesn't this need changing the expectations?

No, because the expectations were not updated in the first place, they were appearing as unexpected crashes.
