Could we somehow get the AVFrame pointer in your custom callback data
or the VmafMetadata data? When all of the expected metadata is written
then you'll know you're ready to forward the frame through the
filtergraph. Doing it this way hopefully avoids a lot of the code and
traversing through linked lists looking for AVFrame pointers as you've
done.

Thanks,
Kyle
