Missing frames at end of test streams

[nicholas-fr]

Test content seems to be missing the last frames (tested with DASH.js):

• 60fps ends on frame 3599 instead of 3601 (3600 with content + last red frame signalling end of content).
• 30fps half frame rate ends on frame 3595 (missing 3597, 3599 + last red frame).

Alternatively the frames could be there & dash.js may not be playing them.
dash.js may terminate playback at the last point there are both video and audio.
@nicholas-fr Check in a video editor if the last frames are actually there.

Checked with VLC v3.0.11 and the last frames are actually present (although VLC also doesn't always play the last frame).
So this was due to DASH client behaviour and not a test stream issue.
Following the explanation Will gave in today's call, I'll have a look into the mezzanine content generation.
It seems plausible that this is in fact caused by how the start/end frames are inserted (without audio).

I did not find anything in the mezzanine generation that would explain this issue.
As such, the most plausible explanation is that it's due to client behaviour.
