I haven't investigated this one in too much depth yet, so there's not a lot of
detail here.

If I run -base/gst/playback/test7 with 2 or more URIs (both files containing
AAC/H264) (You will probably need the patch from #537045 to make this work at
all), then once it gets to the 2nd file, it starts displaying only keyframes.

Looking at the debug output, this is because it's receiving QoS events with a
timestamp around the duration of the first file. Since the timestamps in the
second file are around zero, it thinks everything's very late, and drops back
to keyframe-only mode.

Not sure who is wrong here (ffdec? basesink?).
