I am wanting to do this exact same thing - display the input file creation
time for a few seconds at the beginning of a mov file. I have been messing
with it for several hours now and cannot get anything to show from
I can find no documentation on what metadata keys are actually valid, or
any examples of a working drawtext metadata command. At this point, I'm
guessing that maybe this is "frame" metadata, not "file" metadata, so
creation_time may just not be valid in this context.
I've had more luck using the textfile parameter, so you don't have to try
to escape characters. For example:
./ffmpeg -i mov0.mov -vf
-acodec copy -y output.mov
where format.txt contains simply:
This renders nothing in the output file, though.
I would really love some help here understanding what "metadata" actually
means in the context of the drawtext filter.
