Allows arrangement of multiple windows such as:
ffmpeg -re -f lavfi -i mandelbrot -f sdl -window_x 1 -window_y 1 mandelbrot -vf waveform,format=yuv420p -f sdl -window_x 641 -window_y 1 waveform -vf vectorscope,format=yuv420p -f sdl -window_x 1 -window_y 481 vectorscop
Some changes by Marton Balint:
- allow negative position (partially or fully out-of-screen positions seem to
be sanitized automatically by SDL (or my WM?), so no special handling is
needed)
- only show window after the position is set
- do not use resizable and borderless flags at the same time, that caused
issues in ffplay
- add docs

Create SMPTE ST 12-1 timecodes based on H.264 SEI picture timing
info.
For framerates > 30 FPS, the field flag is used in conjunction with
pairs of frames which contain the same frame timestamp in S12M.
Ensure the field is properly set per the spec.
Currently qsv (m)jpeg encoding is broken.
Regression introducing by the commit(id: c1bcd3): fix async support,
which requires the minimum async_depth to be 1, instead previous zero.
But the default async_depth of qsv (m)jpeg encoding is still initialized
(mostly) as zero.
This patch also abviously improves qsv (m)jpeg encoding performance
due to the default async_depth is changed to 4.

64c50c0e97 declared support for decomposing
them but omitted to implement it; this adds an implementation.
Also do the same for end-of-stream NAL units, since they are equivalent.

There are different the RCV file format for VC-1, vc1test
just handle the case 2 now, this fix will support the case 1.
(Both of test clips come from: SMPTE Recommended Practice -
VC-1 Decoder and Bitstream Conformance). And I think I got
a older VC-1 test clip in the case 1.

Fixes bug with HTTP DELETE when HTTP Persistent is ON.
Right now, HTTP Persistent connections is supported only for POSTs and PUTs.
HTTP DELETE will still open a new connection every time.
Make the function static, or else Clang complains with:
error: no previous prototype for function 'decklink_get_attr_string' [-Werror,-Wmissing-prototypes]

This tries to follow the webrtc code. For example using cliping and 64 bit as in WebRtcSpl_DotProductWithScale()
and not doing so in other places.
I could not find anything in rfc3951 and the reference code inside which would
explain what to do in these corner cases.
