Strange, I tought I had dav1d 0.4.0 build as part of Cinelerra-GG, but apparently build was 
picking up older 0.3.1 I installed via slackbuild!

Recompiling libdav1d 0.4.0 on 32-bit slackware still worked, at least Mplayer + my patch played
webm stream:

mplayer /dev/shm/Stream3_AV3_HD_6.3mbps.webm
MPlayer SVN-r38151-5.5.0 (C) 2000-2019 MPlayer Team

So libdav1d as compiled by its own meson-based build system works on at least some 32-bit x86 CPUs. 
I use Meson because  mesa git (19.3.0) requires it.

Actually libdav1d's Changelog for 0.4.0 says:

Changes for 0.4.0 'Cheetah': 
----------------------------  
- Fix playback with unknown OBUs  
- Add an option to limit the maximum frame size  
- SSE2 and ARM64 optimizations for MSAC  
- Improve speed on 32bits systems <<<<<<<<<<<<<<<<- this
- Optimization in obmc blend  
- Reduce RAM usage significantly  
- The initial PPC SIMD code, cdef_filter  
- NEON optimizations for blend functions on ARM  
- NEON optimizations for w_mask functions on ARM  
- NEON optimizations for inverse transforms on ARM64  
- Improve handling of malloc failures  
- Simple Player example in tools

Just in case you want mplayer patch I attach it 
(added to MPlayer's own tarcker too, but can't recall exact issue #)

What IS not working on 32-bit - https://github.com/OpenVisualCloud/SVT-AV1

I only tried 0.5.0 on 64-bit Slackware....

They have 0.6.0 already:


[0.6.0] - 2019-06-28

    Inital decoder implementation
    Static library support
    Alt-ref pictures - temporal filtering
    Adaptive Transform Block for INTRA
    Adaptive QP scaling
    Decoder - Support for Tiles and 10bit
    API - add option to calculate / report PSNR values
    Support for segmentation
    SIMD Optimizations
    Downsampling 2x2 filtering
    Handle incomplete SBs
    MACROS / trailing / tabs-spaces cleanup

http://ffmpeg.org/pipermail/ffmpeg-devel/2019-July/246488.html
[FFmpeg-devel] [PATCH] lavc: Add libsvt-av1 encoder wrapper

It was not yet merged, as far as I can see ....

THIS one mostly likely will be 64-bit ONLY, because Intel not very interested in 32-bit mode even on new(ish) CPUs, it seems .... ?
But who knows, may be after 1.0.0 someone will fix it up .....
