Disabling explicitly will make sure that the manifest will get generated correctly.

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.

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[1] = x[1] + c2*state + c1*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`.

Fix memory leak after write trailer for #7827, only store a audio
packet whose buffer has size greater than zero in cur_audio_pkt.
Audio packets with size zero, but with side-data currently lead to
memleaks, in the Matroska muxer, because they are not properly freed:
They are currently put into an AVPacket in the MatroskaMuxContext to
ensure that the necessary audio is always available for a new cluster,
but are only written and freed when their size is > 0.
As the only use we have for such packets consists in updating the
CodecPrivate it makes no sense to store these packets at all and this
is how this commit solves the memleak.

Otherwise, AV1 encodes with FFmpeg trigger use-of-uninitialized-value
warnings under MemorySanitizer, and the output buffer potentially
changes from run to run.
