VA-API dmabuf surface balancing doesn't work on NVIDIA:
src/gbm_drv_common.c:56: GBM-DRV error (get_bytes_per_component): Unknown or not supported format: 538982482

NVIDIA perhaps doesn't like dmabuf modifiers when we create a new surface.

That fails with plain surfaces without modifiers too. NVIDIA doesn't allow to create dmabuf objects directly (Bug 1735929). If we want to support it on such hardware, we'd need to create texture first and then derive dmabuf from it as we do in https://phabricator.services.mozilla.com/D147637.

Not sure it's worth the effort as we use it for fallback only when decoding is slow. Perhaps we may disable the decode balancing on NVIDIA and just fail when we're out of free ffmpeg surfaces.
