Silences a warning:
libavutil/hwcontext_qsv.c:912:15: warning: assignment discards 'const' qualifier from pointer target type

Fixes a warning:
libavcodec/libaomenc.c:816:9: warning: unused variable ‘pict_type’

Currently streaming for webm output doesn't work.
Disabling explicitly will make sure that the manifest will get generated correctly.

this patch was originally posted on issue #7704 and was slightly
adjusted to check for the availability of the pixel format.

Fixes ticket #7789.

Cleanup the applehttp as demuxer name, when use the command :

ffmpeg -formats, get the confused information like:
"
 E hls             Apple HTTP Live Streaming
D  hls,applehttp   Apple HTTP Live Streaming
"
we don't use applehttp as the demuxer/muxer name usually, so
cleanup the applehttp and update the documents.

After the change, get the information from "ffmpeg -formats":
"
DE hls             Apple HTTP Live Streaming
"

This is a low speedup, but the x86 mmx version also gets only ~2x. The mmx version
is also heavily inaccurate, while the vsx version has high accuracy.

Total decoder speedup: ~15% on a Raspberry Pi 3 (from 28.1x to 33.5x realtime)

Deemphasis SIMD based on the following unrolling:
const float c1 = CELT_EMPH_COEFF, c2 = c1*c1, c3 = c2*c1, c4 = c3*c1;
float state = coeff;

for (int i = 0; i < len; i += 4) {
    y[0] = x[0] + c1*state;
    y[1] = x[1] + c2*state + c1*x[0];
    y[2] = x[2] + c3*state + c1*x[1] + c2*x[0];
    y[3] = x[3] + c4*state + c1*x[2] + c2*x[1] + c3*x[0];

    state = y[3];
    y += 4;
    x += 4;
}

Unlike the x86 version, duplication is used instead of pslldq so
the structure and tables are different.

The `opencl_get_plane_format` function was incorrectly determining the
value used to set the image channel order. This resulted in all RGB
pixel formats being set to the `CL_RGBA` pixel format, regardless of
whether or not they actually *were* RGBA.

This patch fixes the issue by using the `offset` and depth of components
rather than the loop index to determine the value of `order`.
