When a filter is no longer part of a graph, its pointers should be cleared
so no stale pointers remain.

  h264_parser: eliminate H264SliceContext usage

Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>

Experimental; requires Skylake and VAAPI 0.39.1 (not yet released).
Also increases the allowed range of the quality option - in low-power
mode, the Intel driver supports levels 1-8 (and 0 meaning default).

Non-reference frames (nal_ref_idc == 0) should be discardable, so
frame_num does not advance after them.  Before this change, a stream
containing unreferenced B-frames would be rejected by the reference
decoder.

This prevents attempts to use unsupported modes, such as low-power
H.264 mode on non-Skylake targets.  Also fixes a crash on invalid
configuration, when trying to destroy an invalid VA config/context.

Avoids unwanted parser dependency on dcadata.

This is a video test and there are no audio packets in the sample
anyway.

The current code modifies the user-supplied string, which is shared for
the whole output file. So a bitstream filter specification applied to
multiple streams would not work correctly.

avcodec_copy_context() didn't handle hw_frames_ctx references correctly
which could cause crashes.

This commit enables sending UDP packets in a background thread with specified delay.
When sending packets without a delay some devices with small RX buffer
( MAG200 STB, for example) will drop tail packets in bursts causing
decoding errors.

To use it specify "fifo_size" with "packet_gap" .

The output url will looks like udp://xxx:yyy?fifo_size=<output fifo
size>&packet_gap=<delay in usecs>
