    x86inc: Add stack probing on Windows
    Large stack allocations on Windows need to use stack probing in order
    to guarantee that all stack memory is committed before accessing it.
    This is done by ensuring that the guard page(s) at the end of the
    currently committed pages are touched prior to any pages beyond that.

    aarch64/asm: optimize cabac asm
    0.5% - 2% overall speedup on
    `./x264 --threads X --profile high --preset veryfast --crf 15 -o /dev/null park_joy_420_720p50.y4m`
    cabac is responsible for roughly 1/6 of the CPU use.
    Branch mispredictions are reduced by 15% to 20%.
    cortex-s53: 0.5% faster
    cortex-a72: 2%  faster
    neoverse-n1: 0.9% faster

    Imported from dav1d.

commit 8578bd9f7f7db61bd1e472a6d6ab21b6e8704740

    aarch64/asm: optimize cabac_encode_terminal with extrinsic knowledge
    Approach taken from x86 asm. Overall speedup meaningless.
    cabac_encode_terminal on average twice as fast on cortex-53 while
    encoding with following command:
    ./x264 --threads 1 --profile high --preset veryfast --crf 15 -o /dev/null park_joy_420_720p50.y4m
    Less relative speedup on cortex-a72/73.

    Add a missing include of stdlib.h
    Since 7ab4c928ef4511ea5753a36a57c3506d9fd5086b, osdep.h contains
    calls to malloc/free.
    This fixes building with MSVC targeting WinRT.

    mp4: Remove GPAC Windows Unicode compatibility shim
    GPAC has native UTF-8 support nowadays.
    Also move the compatibility code to input/avs.c since that's the only
    remaining code that uses it now.

    mp4: Fix compiling with recent GPAC versions

Testing this version in xine, parole and vlc shows results are no worse than the previous version ;-) By that I mean that with any of the m4a, mkv, mov, mp4 files I possess there are some which crash the browser, and others where audio is either silent or just random noise (the audio only seems to be a problem in xine). Xine is particularly prone to crashing, but that is not a new development. VLC and parole only crash rarely. Accordingly, I say this version of X264 is "good enough".

Makes me wonder if building Xine is still worthwhile - it used to have better-sounding audio than parole (which uses gstreamer).

Can you give me a sample file? I'm curious as to what it's crashing on...

xine-lib is usable in OpenCV and liba52 as well I think, not really sure what it's used for though

Replying to renodr:

I don't recall which purchased files crashed any of them, and anyway they are generally far too large to upload. A quick review of the smaller mp4, mkv files I have that are probably shareable (you-tube downloads) didn't find any that crash any of them. My own camera's mov files continue to crash xine (but ok in parole, vlc), I have a 6 second 25MB mov (steam train waiting to depart, until I realised it was not close to setting off) I can share for testing, contact me privately if you want it.

I will note here that one of my old (2011) mp4 conversions of my own mov files, which mediainfo says was written by x264 core 115 files (less than 21s, 14M instead of the 77M mov) plays ok in current xine on at-video r600, ISTR that too crashed xine - at least on intel - at some past time. That is also available for testing if anyone wants it.
