Fixes #4140.

Fixes #5700.

It is unsigned at least on arm, fixes the following warnings:
libavfilter/vf_signalstats.c:833:21: warning: taking the absolute value of unsigned type 'unsigned int' has no effect
            dify += abs(yuv - AV_RN16(prev->data[0] + pw + i * 2));

The issue is that the afq still has samples as on init it counts
the overlap used as a delay to adjust the PTS it generates, hence
we can't rely on it right after init.
So just check to see if any frames have been encoded. frame_number
can't be anything but 0 right after init and can only be set by lavc.

Prevent test failure with builds that set a suffix and/or
extension for the ffprobe binary

this section has been moved into the CONFIG_NETWORK block, since it only
affects network enabled builds.

sys/socket.h (with WIN32 guard) is needed to check if the SHUT_xxx macro exists.

Anyways the intended behaviour was to disable SIDX atom.

Option name is dvbuffer.

The max size of uint8_t subset is 223 not 220.

Fixes ticket #6234.

Fixes #6874.

before this change, scale_vaapi hard coding the scaling mode, add a
new option "mode" to setting the scaling mode, it can be use to change
scaling algorithm for performance/quality trade off.

Note: VA_FILTER_SCALING_NL_ANAMORPHIC(nolinear ananorphic scaling
algorithm) doesn't support by i965/iHD driver now, add this just for
completeness.

Fix the (m)jpeg encoding regression issue as decription in tikect #7593,
due to bs->FrameType is not set in such case in
MSDK (https://github.com/Intel-Media-SDK/MediaSDK/issues/970).
(And assert on a value coming from an external library is not proper.)

Add default type check for bs->FrameType, and return invalid data error in function
ff_qsv_encode to avoid using uninitialized value.

Assertion avctx->codec_id != AV_CODEC_ID_NONE failed at src/libavcodec/parser.c:128

The setting on the internal AVCodecContext used for parsing only is
otherwise irrelevant, so just set it to avoid the assert.
