that it's about 1.65x as fast as the AVX version for the full IDCT, and

This is an - once again - updated patch, that uses avio_write instead
of avio_puts to stream clean text output without null characters. Works
now for me as intended.

Changes metadata filter to accept general urls as file argument without
breaking former behaviour. As a byproduct, it also allows for writing to
file "-" if specified as "file:-".

Example:

ffmpeg -i test.wav -filter_complex "silencedetect=n=-40dB:d=0.1,ametadata=mode=print:file='pipe\:4'" -f null

"The call point is left where it was before. Such a change should be in
a separate commit and has multiple issues, one being null pointer
dereferences the other is that some safety checks would become
conditional.

I tried to split the PPS init between the new and old functions
similarly to the SPS code."

We know the maximum size of an AnnexB NAL, signaling it as the maximum
NAL size allows ff_h2645_extract_rbsp to determine the correct size.

Reading it from any other position would result in a wrong size being
read, instead fallback to the re-sync mechanic in the else clause.

Gray encoding crashes with libx265 <= 84, so check the library version.

H264ParamSets has its SPS/PPS stored raw (SODB) and needs to be
converted to NAL units before sending them to MediaCodec.

This patch adds the missing convertion of the SPS/PPS from SOBP to RBSP
which makes the resulting NAL units correct.
