a246d06fe0 hevc: clip pixels when transquant bypass is used
The reconstructed picture should always be clipped (see section 8.6.5),
previously we did not clip coding units where
cu_transquant_bypass_flag == 1.

e34ad128a3 examples/muxing: reduce duration, remove wrong and misleading comment
Set duration to 10 seconds, after it was increased from 5 to 200 seconds
in 8d80f3cb87.

200 seconds will generate too much data which is annoying especially when
testing.

  mov: do not set avg_frame_rate in the demuxer

Conflicts:
	libavformat/mov.c

Not merged
The default fallback code that sets avg_frame_rate guesses the value
from a very small number of frames at the videos start and is wrong in
some cases for the file as a whole.
Now that makes it guess vs guess, but the code in mov is much faster

Also ideally the mov code should be fixed and give a exact avg_frame_rate
based on the actual cts from the index (CTTS/STTS)

If someone has sample(s) which show wrong fps values, please open a ticket
on trac or mail me if its private.

dd2d0039b6 vc1: Always reset numref when parsing a new frame header.
Fixes an issue where the B-frame coding mode switches from interlaced
fields to interlaced frames, causing incorrect decisions in the motion
compensation code and resulting in visual artifacts.

d01e684186 mov: do not set avg_frame_rate in the demuxer
The track duration is often not reliable or is not the duration
represented by the number of frames. In those cases, avg_frame_rate
was reported incorrectly. Removing this code falls back to the
default calculation in avformat_find_stream_info().

This is a partial revert of commit c3aeaa540.
