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..

FFmpeg crop example: crop the 100x100 pixels top right section of a video. Example in which we'll use the input.
  5. The movie filter currently does not allow infinite input looping via the loop option.. The loop_count is decremented with every completed loop and stops at 0.. There should be a way to set the loop option to -1 which would enable infinite looping. (I can have a try at this but I'm not sure if there's something that prevents it from being implemented in the filter section.

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.. Streams means video, audio, subtitles, attachments and data within the file; this is rather complex on movie files where there could be multiple audio streams for different languages and the same for subtitles Tutorial 03: Playing Sound Code: tutorial03.c Audio. 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.
