8076609a40 The NSV demuxer assumes that a video frame's timestamp increases by one on each 
frame, but some low-bitrate NSV files omit video frames for some NSV frames,
and expect the timestamp to increase by one every NSV frame. This is noticeable
in 64vp3.nsv where the video runs several times faster than the audio. Fix this
by unconditionally incrementing the video's timestamp with each NSV frame.

df7625ed62 av_estimate_timings_from_pts() flushes the packet queue but doesn't 
reset the streams' cur_dts values.  This can lead to a fatal "error,
non monotone timestamps ..." message later, because the out-of-date
cur_dts values are used to compute some packet's dts.

Fix this by calling av_read_frame_flush() and eliminate code
duplication in the process.

The additional hunk gives more detailed error messages.

At the end of a nut file, the check for url_feof() fails because the

the index packet.    This patch fixes this
