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 224 audio & 465 video codecs Playing /dev/shm/Stream3_AV3_HD_6.3mbps.webm. libavformat version 58.32.104 (internal) libavformat file format detected.

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 https://code.videolan.org/videolan/dav1d/blob/master/NEWS 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....
