Comment (by Brainiarc7):
Here's the workaround:
Add this filter argument to hwupload:
hwupload=extra_hw_frames=1234 (replace with suitable value, probably
something like 10 works for you here).
'''Rationale:'''
The filter option extra_hw_frames passed to the hwupload video filter is
used to set an initial pool size.
For the settings, if it's feeding into a scaler, then probably 2 or 3
frames are sufficient, but if it's feeding into an encoder with look-ahead
enabled, then you might need over 100. As such, it's currently under user
control.
