I currently cannot reproduce the Segmentation fault, just the MemoryError
above. Probably a memory layout thing that might or might not segfault.

However, that doesn't seem to make sense:
# ffmpeg -codecs | grep 264

(decoders: h264 h264_vdpau ) (encoders: libx264 libx264rgb )
pjsip_trace.txt shows some stuff too which indicates it does in fact
find my devices, but then screws up somehow:
