Test Content long duration for Test 9.6

[louaybassbouss]

DPCAT Test 9.6 Long Duration Playback requires long duration content. Not sure about appropriate duration @dsilhavy @jpiesing any recommendation? I can remember a discussion of 1h content but not sure.

I see it's been assigned to me but what can I do about it? What would be the associated mezzanine content?

As a proposal we could ask gpac to generate a one hour long beepbop counter a/o mix some continuous audio with it?

@nicholas-fr is working on the mezzanine content for this.

For the audio portion, I think we discussed looping the PRN file. This gives a mod 60s timing result, which should be OK for most purposes. If something is off by more than 59 seconds, it is unlikely to be off by exactly 60s (or 120s, etc.), so the audio tests will still flag an error.

Just to make sure I understand correctly: it is expected that we loop the audio input to match the video input duration, correct?

@nicholas-fr has just uploaded some mezzanine for long duration, it just needs encoding. Long duration is a lower priority though than chunked content as long duration is only a 'nice to have' for the 1st release.

Deferred to future work.

Is https://dash.akamaized.net/WAVE/Mezzanine/releases/3/tos_LD1_1920x1080@30_7200.mp4 considered like the source content for this issue?

Also, could we update the sparse matrix to indicate which parameters to use? (I guess any, so I would copy them from T1?)
