mpeg12dec: move setting first_field to mpeg_field_start()
This commit is a noop, see 2f6f2f4f73
Merged-by: James Almer <jamrial@gmail.com>
So, all frames and errors are correctly reported in order.
Also limit the numbers of error during draining to prevent infinite loop.
This fix fate failure with THREADS>=4:
make fate-h264-attachment-631 THREADS=4
This also reverts a755b725ec.

This merge is a noop.
2017-04-29 12:54:15 @ubitux michaelni: is 740959fdbf enough to fix the overflow fixed in 58405de0951a843765625159402870c1eea3c3b1?
2017-04-29 12:55:53 @ubitux same question with e807491fc6
2017-04-29 13:21:45 michaelni ubitux, the libav code refered to is wrong for us and i doubt the problem it fixes applies to us.
2017-04-29 13:24:29 @ubitux michaelni: ok, for both commits?
2017-04-29 13:33:55 michaelni yes, they do more or less the same thing

hevcdec: add a VAAPI hwaccel
This commit is a noop, see adb54e59c1
Merged-by: Clément Bœsch <u@pkh.me>
find_fps attempts to infer framerate from AVCodec's timebase. When this
results in a frame rate that isn't explicitly marked as supported in
av_timecode_check_frame_rate, find_fps returns the AVStream's
avg_frame_rate, which, per avformat.h, _may_ be set (or not).
mov_get_mpeg2_xdcam_codec_tag, mov_get_h264_codec_tag and
find_compressor attempt to call av_q2d on the return value of find_fps,
which in the above case, may result in division by zero and therefore,
an undefined frame rate when NaN is converted to int.

Most code between the 2 functions was duplicated which made keeping
both in sync difficult.
This also fixes some discovered issues with encoding (incorrect
TF switching buffers) and reduces stack usage (reuse the already
allocated CeltFrame->scratch buffer for the quantized coefficients).

This patch aims to reduce the number of input/output surfaces
NVENC allocates per session. Previous default sets allocated surfaces to 32
(unless there is user specified param or lookahead involved). Having large
number of surfaces consumes extra video memory (esp for higher resolution
encoding). The patch changes the surfaces calculation for default, B-frames,
lookahead scenario respectively.
The other change involves surface selection. Previously, if a session
allocates x surfaces, only x-1 surfaces are used (due to combination
of output delay and lock toggle logic). To prevent unused surfaces,
changing surface rotation to using predefined fifo.
