FFMPEG Video loop from images files. Ask Question Asked 1 year, 3 months ago. Active 3 months ago. Viewed 1k times 0. I am trying to make a video from a bundle of image files and then apply a an overlay on top of it.Another requirement is to make the video loop 3x. It is simply not working $ ffmpeg -loop 1 -i inputimage.jpg -i inputaudio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4 15. Trim a media file using start and stop times. To trim down a video to smaller clip using start and stop times, we can use the following command ffmpeg -i input.mp4 -ignore_loop 0 -i input.gif -filter_complex overlay=shortest=1 out.mkv Note that in the above example the shortest option for overlay filter is used to end the output video at the length of the shortest input file, which in this case is input.mp4 as the GIF in this example loops infinitely

4.2 Notes on filtergraph escaping. Filtergraph description composition entails several levels of escaping. See (ffmpeg-utils)the Quoting and escaping section in the ffmpeg-utils(1) manual for more information about the employed escaping procedure..

There should be a way to set the loop option to -1 which would enable infinite looping.

On ffmpeg, the -loop input option currently only works for image2 format and not for videos using the file protocol. This is somewhat surprising once ffplay can loop over a video file with the -loop option. Also, the concat demuxer should allow this behavior without much work 3. Just use what is built into ffmpeg to do exactly this. ffmpeg -i invid.mp4 -threads 3 -vcodec copy -f segment -segment_time 2 cam_out_h264%04d.mp4. This will split it into roughly 2 second chucks, split at the relevant keyframes, and will output to the files cam_out_h2640001.mp4, cam_out_h2640002.mp4, etc. Share

Map in FFmpeg can be best understood as selecting streams within a file you want to encode, keep or remove when creating an output.-map is the command..

So now we want to play sound. SDL also gives us methods for outputting sound. The SDL_OpenAudio() function is used to open the audio device itself.
