When decoding with threads enabled, the get_format callback will be
called with one of the per-thread codec contexts rather than with the
outer context. If a hwaccel is in use too, this will add a reference
to the hardware frames context on that codec context and then use it
for decoding. Once the decoder finishes, however, the per-thread
context is not freed normally, so this reference leaks.

I assume there is a good reason why the per-thread contexts are not freed
normally with avcodec_free_context()?
