This avoids using the CUDA SDK at all; instead, we provide a minimal
reimplementation of the basic functionality that lavfi actually uses.
It generates very similar code to what NVCC produces.
The header contains no implementation code derived from the SDK.

Isn't this about variable (or "changing") "resolutions" instead of dimensions?

Hello,
I've been looking for a way to stream to multiple clients without using a
multicast destination address or an external server.
I believe ZeroMQ, which is a lightweight asynchronous messaging library, is a
possible option. It is already part of ffmpeg and can be used to
forward messages

Here's a snippet of how I'm doing it right now:
This makes the code bitexact between platforms.
Intermediate timestamps between frames are preserved.
The timebase is simplified.
Rounding differs from doubles in cases where timestamps/durations
are "funny"

Flush encoders when resolution change happens.
Use AV_CODEC_CAP_PARAM_CHANGE flag for encoder to indicate whether
it supports variable/dynamic resolution encoding.

Currently, ffmpeg inserts scale filter by default in the filter graph
to force the whole decoded stream to scale into the same size with the
first frame. It's not quite make sense in resolution changing cases if
user wants the rawvideo without any scale.
Using autoscale/noautoscale to indicate
According to spec, libvpx should support dynamic resolution changes.
Add dynamic resolution encoding support in libvpx.
Format change should also be supported, but I didn't test it so just
leave it open.
