--- Comment #2 from Víctor Manuel Jáquez Leal <vjaquez at igalia.com> ---
as far as I read, the problem relies on the fact that the vaapi decoder only
has a limited number of output buffers, and it waits until they return back to
the pool in order to provide more.

I don't know you code, but it looks to me like if you are holding those
buffers.

A workaround would be to place a vaapipostproc right after the decoder, so the
postprocessor could create any number of output buffers, limited only by the
memory (gpu or cpu depending on the backend).
