Add it to decoder options instead, to be processed when opening the
decoder. This way it won't be overridden by flags the user might be
setting otherwise.

'struct bar', which requires # byte alignment" errors under GCC ubsan.

Fixes server compatibility issues with rtspclientsink GStreamer plugin.
>From specification:
RFC 7826 "Real-Time Streaming Protocol Version 2.0" (https://datatracker.ietf.org/doc/html/rfc7826), section 18.54:
mode: The mode parameter indicates the methods to be supported for
this session. The currently defined valid value is "PLAY". If
not provided, the default is "PLAY". The "RECORD" value was
defined in RFC 2326; in this specification, it is unspecified
but reserved. RECORD and other values may be specified in the
future.
RFC 2326 "Real Time Streaming Protocol (RTSP)" (https://datatracker.ietf.org/doc/html/rfc2326), section 12.39:
mode:
The mode parameter indicates the methods to be supported for
this session. Valid values are PLAY and RECORD. If not
provided, the default is PLAY.
mode=receive was always like this, from the initial commit 'a8ad6ffa rtsp: Add listen mode'.
For comparison, Wowza was used to push RTSP stream to. Both GStreamer and FFmpeg had no issues.
Here is the capture of Wowza responding to SETUP request:

Previously AV_PIX_FMT_RGB8 was documented as "RGB 3:3:2,
(msb)2R 3G 3B(lsb)". While the RGB 3:3:2 part is correct, the latter
part should be: (msb)3R 3G 2B(lsb). This commit also updates the
format's pixdesc description to be (msb)3R 3G 2B(lsb).

This is the 64bit version of Chris Doty-Humphreys SFC64
Compared to the LCGs these produce much better quality numbers.
Compared to LFGs this needs less state. (our LFG has 224 byte
state for its 32bit version) this has 32byte state
Also the initialization for our LFG is slower.
This is also much faster than KISS or PCG.
This commit replaces the broken LCG used before.
(broken as it had only a period ~200M due to being put in a double)
This changes the output from random() which is why libswresample.mak
is updated, update was done using the command in libswresample.mak

As I understand, support for .STR files is broken for almost 10 years now (since 161442ff2c it seems).
Currently, ffmpeg fails with tons of errors like this on version 1 STRs, e.g. Wipeout 1:
[mdec @ 00000000027c72c0] ac-tex damaged at 1 9
What happens is that only the audio is present in the video file.
Anyway, that one character patch fixes the problem, video is now rendered.

On some platforms (in particular, ARM/AArch64), the implementation
of AV_READ_TIME() may use a privileged instruction - in such
cases, benchmarking just fails with a SIGILL.
Instead of crashing, try executing AV_READ_TIME() once within
a region with the signal handler active, to allow gracefully
informing the user about the issue.
This matches the dav1d checkasm commit
95a192549a448b70d9542e840c4e34b60d09b093.
