That's what it looks like for me:
https://bpaste.net/show/890855410dac
Happens on two independend machines, on both Windows using MSVC and
Linux with gcc.
Both machines are definitely nowehre near out of memory, on either
system or device memory.

Can't reproduce it on two my systems with same sample and same command
line.

That's not built from the right branch.
Most notably: On the filter-merge branch, the cuvid pfnSequenceCallback
happens before the "Nvenc initialized successfully", on your log Nvenc
still gets initialized first.

It is problem in NVENC.
You create first frame before initialization of NVENC in CUVID, so this
first frame is not accesible to NVENC until
dl_fn->cuda_dl->cuCtxPushCurrent(ctx->cu_context) is called in NVENC.
This trivial patch should fix your problem.
