From: Pavel Koshevoy <pkoshe...@gmail.com>
NVDEC (CUVID) does not support unlimited video resolutions, so if the
resolution of the source is known it can be used during avcodec_open2
call to fail early, rather than failing later during
avcodec_send_packet call.
This problem surfaced when trying to decode 5120x2700 h246 video on
Geforce GT 730 -- avcodec_open2 succeeded but decoding failed.
