I copied this command ffmpeg -framerate 1/5 -i img%03d.png -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4 from https://trac.ffmpeg.org/wiki/Slideshow but everytime I run it I get the error of:

"Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height"

And if I move the output like this: ffmpeg -framerate 1/5 -i img%03d.png out.mp4 -c:v libx264 -r 30 -pix_fmt yuv420p then a video is created, it say 5-10 seconds, but the progress bar does not move and it is just black.

I've also looked at How to create a video from images with FFmpeg? but I basically get the same results.

Is there anything that I'm missing? Any feedback would be appreciated, thanks.

  • Okay thanks I'll edit my question. – Ted Bed Nov 23 '20 at 20:23

    `width not divisible by 2`. New command as shown in duplicate question [FFMPEG (libx264) “height not divisible by 2”](https://stackoverflow.com/a/29582287/): `ffmpeg -framerate 1/5 -i img%03d.png -c:v libx264 -r 30 -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2,format=yuv420p" out.mp4` – llogan Nov 23 '20 at 20:37
  • Okay thanks, just now if I use a command like this: `ffmpeg -framerate 30 -i img%03d.png -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -pix_fmt yuv420p video.mp4` it only uses and show the last image in the series. Could you help me with this? Also is there a forum like slack so I could ask more informal questions like this? – Ted Bed Nov 23 '20 at 21:37
  • I heard of an unofficial ffmpeg Discord (I think that's the platform) channel but I've never used Discord. If you use IRC see #ffmpeg which is official. As for only last image showing, do all of your images have the same attributes? Width, height, format, etc? – llogan Nov 23 '20 at 23:11
  • All of the images are pngs but they have different heights and widths. – Ted Bed Nov 24 '20 at 00:50
  • They all have to be the same. You can do this by using filters in ffmpeg. See example *Using input images that each vary in size* in answer to [Resizing videos with ffmpeg to fit into specific size](https://superuser.com/a/1136305/). – llogan Nov 24 '20 at 02:53
  • I tried `ffmpeg -framerate 30 -i img%03d.png -vcodec libx264 -y -an -vf "scale=1280:720:force_original_aspect_ratio=decrease:eval=frame,pad=1280:720:-1:-1:color=black" -pix_fmt yuv420p video.mp4 2>&1` and it somewhat worked 1 time, but I can't seem to replicate the result anymore. Now it again only shows the last image. – Ted Bed Nov 24 '20 at 06:18
  • It's a new problem than your original question. You can ask a new question (at [su] so it doesn't get closed here at [so] which is for programming questions). Make sure to show your command and the complete log. – llogan Nov 26 '20 at 03:39
  • Okay thanks I'll look there for future questions. Luckily I found a solution to my problem, thanks for helping me get there. – Ted Bed Nov 27 '20 at 04:37
