installing with apt-get install ffmpeg causes Segmentation fault but a build from source works correctly
I did a rebuild of ffmpeg 4.3 and that fixed it but had to do it on a 8Gb model as the 1GB Raspberry Pi 4 Crashes with out of memory.

A smaller j value would likely have worked on a Pi4. Increasing swap should also work.
@XECDesign with both repos updated: On 32-bit:
ffplay version 4.3.3-0+rpt3+deb11u1 Copyright (c) 2003-2021 the FFmpeg developers
built with gcc 10 (Raspbian 10.2.1-6+rpi1)
On 64-bit:
ffplay version 4.3.4-0+deb11u1 Copyright (c) 2003-2021 the FFmpeg developers
built with gcc 10 (Debian 10.2.1-6)
Is the 64-bit ffplay built from @jc-kynesim's repo, or is it built from vanilla upstream debian ffmpeg?
I think there was recently an embargoed ffmpeg update, which I haven't had a chance to add yet. Since Raspbian lags behind, it hasn't received it yet. Updated version should be up later today.
The packages were updated last week. Did that help at all with the issue, or are you still seeing the segfault?
for me it only worked like this:
sudo apt-get update -qq && sudo apt-get -y install autoconf automake build-essential cmake git-core libaom-dev libass-dev libfreetype6-dev libgnutls28-dev libsdl2-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo wget yasm zlib1g-dev libunistring-dev libdrm-dev libopus-dev libvpx-dev libwebp-dev libx264-dev libx265-dev libxml2-dev libmp3lame-dev

Had to remove libfdk-aac from apt-get (not found), had to install the download libfdk-aac libraries, and had to change arch to arm on configure options.
