How can I display a sequence of png files for different time
durations and mate them with a single audio?
Attached is a toy example: I want to display tst1.png for 0.5
seconds followed by tst2.png for 1.5 seconds and merge that video with
the audio in tst2.mp2.
If I don't care about the display time for each image, I can
merge these 2 png and 1 mp2 files with "ffmpeg -y -r 1 -i tst.mp2 -r 2
-i tst%d.png -b 300k tst.mp4".
The documentation describes "concat" for filter, demuxer,
protocol, and raw. I was unable to see how any of these would solve
this problem.
Thanks,
Spencer
