[FFmpeg-user] OVERLAY_CUDA and PGS Subtitle burn

Hi everyone,

i'm trying to use the OVERLAY_CUDA function to burn PGS titles over a video
and the result is not working.
i might  misunderstand the usage of this function, so some help is welcome.

The result of this command is a black screen with audio, using 'standard'
overlay filter is working fine, but slow ...

Notice this message at the end of the log file (ffmpeg version
N-99194-g142ae27b1d ( compiled myself from git) ):
*Error while add the frame to buffer source(Internal bug, should not have
happened).*

Thanks for any help.
