[GStreamer][MSE] Parser should be replaced when caps change in the append
pipeline
https://bugs.webkit.org/show_bug.cgi?id=245518
Reviewed by Philippe Normand.
In the cases of some transitions, for example from unencrypted to encrypted
content,
the demuxer creates a new pad that we try to link to the the existing track
but the parser won't link with those new caps so we need to replace it.
This patch ensures that, when unlinking and relinking, we have the right parser
by
removing the old one and creating a new one for the given caps.
Test: media/encrypted-media/encrypted-media-append-encrypted-unencrypted.html.
For the test we are using the media-source-loader-simple but it was needed to
enhance it
to be able to apply timestamp offsets and so to be able to wait until
all appends are done before checking the final result. In this case, it's the
duration.
