) |
Associate a VDPAU device with a codec context for hardware acceleration.
This function is meant to be called from the get_format() codec callback, or earlier. It can also be called after avcodec_flush_buffers() to change the underlying VDPAU device mid-stream (e.g. to recover from non-transparent display preemption).
avctx | decoding context whose get_format() callback is invoked |
device | VDPAU device handle to use for hardware acceleration |
get_proc_address | VDPAU device driver |
flags | zero of more OR'd AV_HWACCEL_FLAG_* flags |
