[FFmpeg-user] make slideshow ?

[Taner Sener]

I tried the following scripts. They create videos but they are very slow
compared to libx264. Other than that, I didn't have any problems.


ffmpeg -y -f concat -safe 0 -i tempFile.txt -codec:v libtheora -qscale:v 4
slide_show.ogv


ffmpeg -y -f concat -safe 0 -i tempFile.txt -c:v libvpx-vp9 -deadline
realtime slide_show.webm
