DPCAT - incorrect contents are used

[yanj-github]

The following tests are required to have Two CMAF Switching Sets but only one is used.

• source-buffer-re-initialization-without-changetype
• source-buffer-re-initialization-with-changetype
• truncated-playback-and-restart

[FritzHeiden]

I've added the second switching sets to the source buffer reinitialization with and without changetype tests. Please note that they don't yet have their proper test content.
The truncate test requires some additonal work, also related to #83, to utilize multiple switching sets

[FritzHeiden]

@yanj-github the truncate test now uses the content suggested by the specification.

@yanj-github can we close this.

[yanj-github]

I am happy to close it assume that we are waiting to get right content for:

• source-buffer-re-initialization-without-changetype
• source-buffer-re-initialization-with-changetype

I am happy to close it assume that we are waiting to get right content for:

* source-buffer-re-initialization-without-changetype

* source-buffer-re-initialization-with-changetype

We are waiting for some HEVC content for these two. They are currently de-prioritised for this reason.

Thanks @jpiesing
It is fine to us, can you confirm for truncated-playback-and-restart test, splice_main and splice_ad are right streams to use please?

[louaybassbouss]

ok lets keep it open for now until content is available and everything is tested

Keep open until final content is created/tested.

The correct content is available.
