The scene: Ubuntu 16.04, newly upgraded from 14.04 where things perked along happily with avconv
The props: a directory full of stills, motor_animate_000.gif, motor_animate_001.gif, etc.
The players: Me, a mostly-newbie ffmpeg user, and ffmpeg.
Based on a suggestion I had to solve another problem, I execute the command line:
ffmpeg -f image2 -framerate 30 -i motor_animate_%03d.gif motor.mpg
After the usual excrutiating detailed list of stuff from ffmpeg, I get the following error message (in more than one color, ooh, ooh).
[image2 @ 0x14f8420] Could not find codec parameters for stream 0 (Video: none, none): unknown codec Consider increasing the value for the 'analyzeduration' and 'probesize' options motor_animate_%03d.gif: could not find codec parameters Input #0, image2, from 'motor_animate_%03d.gif': Duration: 00:00:04.03, start: 0.000000, bitrate: N/A Stream #0:0: Video: none, none, 30 fps, 30 tbr, 30 tbn, 30 tbc File 'motor.mpg' already exists. Overwrite ? [y/N] y No decoder for stream #0:0, filtering impossible Error opening filters!
Can anyone tell me what's going on and how to fix it? All I want to do is make an mpeg clip out of a bunch of one-frame gifs.
