NVEnc Preview
#3
The idea from _Al_ was to use ffmpegs filters by:
a. feeding raw video to ffmpeg
b. filter it through ffmpeg
c. output raw video from ffmpeg
d. capture that raw output and replace the memory space the unfiltered framed occupied with the raw output of ffmpeg.
This can work input&output resolution and format did not change.
You use:
-f,--output-format <string>     set output format of output file.
                                 if format is not specified, output format will
                                 be guessed from output file extension.
                                 set "raw" for H.264/ES output.
with NVEncC, which instead of ffmpeg:
-vcodec rawvideo -pix_fmt yuv420p -f rawvideo
does not output RAW YUV420P8 content, but raw H.264 !
This will not work, what will happen is that you only replace parts of the original frame info with the compressed H.264 output, so you will get half broken frames.
To get this working, you would need to decode the raw H.264 frames back to raw yuv420p8.
