• ffmpeg video slideshow only takes first image

  14 décembre 2018, par Erhan

  I wanted to create an .mp4 video with a framerate of 1 fps out of 10 images. I followed https://trac.ffmpeg.org/wiki/Slideshow and got to (my images are in the folder I am running the command from and are name img000.png, img001.png, etc.)

  path_to_ffmpeg\ffmpeg.exe -framerate 1 -i img%03d.png output.mp4

  However only the first image is taken to the video and it only shows one image !

  After trying multiple permutations of -framerate and -r options and positions of the options, I did not recieve any better results.

  Does anyone know what might have gone wrong even in this simple case ? Thanks.

  The problem is that the mp4 has 00:06:45 duration, and the music finished at 00:05:28

  How do I chop the last silent bit off ?

  I tried the following :

  ffmpeg -ss 0 -i 20170817.mp4 -to 00:05:28 -c copy cut.mp4

  Which is worse. Adds blank silent video at front, and chop the video at middle which yet to finish.

  Please note the first 5 images are correct at right music positions, only last image duration error

• flvEncoder .flv output won't convert to .mp4 with ffmpeg

  31 juillet 2013, par Emma Assin

  My current project involves creating a .flv using AIR (using https://github.com/zeropointnine/leelib/tree/master/src/leelib/util/flvEncoder) - which then has to be converted into an .mp4, for which we are using ffmpeg.

  The .mp4 output is the correct dimensions and duration, but blank (no images). Audio is not an issue as the original output has no audio.
