The new functions are going to be shared by other filters.

This ensures the tools are rebuilt when necessary.  Specifically,
lavfi-showfiltfmts was sometimes not rebuilt causing spurious test

This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic.  These include clang and some BSD versions.

All AVX code will be written for yasm, where the main assembler
is not involved.

Update libavformat/version.h and doc/APIChanges after renaming
init_put_byte() and ByteIOContext to ffio_init_context() (private)
and AVIOContext, (public), and deprecating the originals.

init_put_byte should never be used outside of lavf, since
sizeof(AVIOContext) isn't part of public ABI.

Advanced profile never uses "range reduction", so vc1_put_block() quite
literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv().
By inlining the function, we can prevent calling IDCT8x8 if
CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the
[0,256] range, but can instead use put_signed_pixels_clamped().

This adds configure and runtime checks for AVX support on x86 CPUs.

Remove ff_vector128, it is identical to ff_pb_80.

Patch discussed and taken from https://roundup.ffmpeg.org/issue2584

With negative stride, the start of the edge_emu buffer should be pointing to
the last line, not the end of the buffer.
With positive stride, pointing to the end of the buffer was completely wrong.

Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't
use an MPEG-like quantizer scale.

This one didn't actually need to be initialized.

On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files.  This is generally bad, as most of these
functions are smaller inlined than not.

If the client sends PLAY/PAUSE requests with the same url as
specified in Content-Base, these requests may have urls with
trailing slashes.

3*n4 was already calculated in n3.

The rematrixing strategy reuse flags are not reset between frames, so they
need to be initialized for all blocks, not just block 0.

If udp_read_packet returns 0, rtsp_st isn't set and we shouldn't
treat it as a successfully received packet (which is counted and
possibly triggers a RTCP receiver report).

This fixes issue 2612.

Hi.

It seems that ffserver sets sample_aspect_ratio to an invalid value and lavf
rejects it.

I am not sure what I am doing here, but the attached patch actually solves
something: using the following config:

CustomLog -
NoDaemon
RTSPPort 5454
<Stream test1-rtsp.mpg>
Format rtp
File "/tmp/test1-rtsp.mpg"
</Stream>

it allows a somewhat old ffplay (unaffected by the content-base issue I
spoke of in another thread) to play the stream.

Without it, ffserver logs this and closes the stream:
