[Bug 729371] dash/qtdemux: Reported video size does not correspond to what avdec_h264 states

[GStreamer (GNOME Bugzilla)]

--- Comment #7 from A Ashley <bugzilla at ashley-family.net> ---
I think Thiago got it right back in 2014 - dash/qtdemux will report the
largest, but avdec_h264 will be reporting the actual values from the last
SPS/PPS that it has decoded.

I think that 5.1.4 of DVB DASH is the relevant section:

5.1.4 Signalling within the AVCSampleEntry in an initialization segment

The AVCSampleEntry contained within the initialization segment of an H.264/AVC
track contains a number of values indicating information about the encoded
video. These values shall always be set such that the encoded video in all
Representations using this initialization segment does not exceed the size,
profile, level or compatibility indicated within the initialization segment,
however the values are not required to indicate the exact size or nature of the
specific stream.
