> gstavviddec.c:862:gst_ffmpegviddec_get_buffer2:<avdec_h264-0> alloc failed, fallback alloc

Which is the result of gst_buffer_pool_acquire_buffer() failing. Digging a
little more:

> xvimagepool.c:199:xvimage_buffer_pool_alloc:<xvimagebufferpool2> can't create image

Which points to xvimagesink proposing a pool that does not work, and the
fallback allocation in libav decoder not working. Very few element have such a
fallback, so first issue is major issue for OpenBSD. The second, we can try and
simulate the error and fix.
