Update: I noticed YouTube has difficulty processing the video (gets stuck at 95%) I think because there's only one frame. I've googled around and found a dozen of proposed solutions (supposedly to this very same question) none of which works.Ĭan anybody suggest a working command and explain the rationale behind it?įFmpeg will try to pick the best codec automatically, depending on the extension of your output file. I tried: ffmpeg -i image8.jpg -i sound11.amr -acodec copy test.aviĪnd tried a lot of combinations with and without -s 640x360, -loop_input, -shortest, -t xxx, -r 0.1 (artificially low frame rate in the hope that the video would be longer) and -f image2Įither I get errors or I get a video file of the duration of one frame. What is the right command line that would do that? copy the audio stream without transcoding it). I don't care very much about what video codec is used for output, but it is vital that I can use 'copy' as the audio codec (i.e.

I want FFmpeg to take one JPEG image and an audio file as input and generate a video file of the same duration as the audio file (by stretching the still image for the whole duration). This should be pretty trivial, but I can't find a way to get it to work.
