• 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.

• FFMPEG, H264 Encoding : If frame size exceeds level limit, does it lead to video encoding failed ?

  4 février 2021, par Nafia Mahjabin

  I want to reencode an mp4 file with h264 encoding.
Run the following command :

  


  


  ffmpeg -i input.mp4 -f mp4 -vcodec h264 -profile:v baseline -level 3.0 -pix_fmt yuv420p -color_range 2 -vf scale=1080:1920 -acodec aac -async 1 output.mp4

  


  


  Process fails saying Video encoding failed.

  I tried to figure out the reason for fail. I'm guessing from error message from the line frame MB size (68x120) > level limit (1620), frame size exceeds h264 level limits may be the issue.

  


  Is it the issue ? if it is, what's the solution for this ? if it's not, what went wrong ?

  


  Can somebody help please ? Thank you !

  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
