Thanks for this! Comes in handy.
Rather than using the ffmpeg
-t 1option to read 1 second, I've found it works to use the-frames:v 1option on the output side (after the-ioption, e.g.,-i `"$fn`" -c:v copy -frames:v 1) to only output the first frame, since that's all dovi_tool needs to read.So it can process a file faster by only processing a single frame.
