My question has been answered, see this thread: How can I place a still image before the first frame of a video? Unfortunately, the non-audio solution is not working for me. I have an input BMP file, and input CINE file [written by Vision Research SDK], and wish to produce an output MP4 file. I pass the following command:
ffmpeg -y -r 100 -loop 1 -framerate 100 -t 1 -i c:\x.bmp -i c:\x.cine -filter_complex '[0:0] [1:0] concat=n=2:v=1:a=0' c:\x.mp4
And get error message:
[AVFilterGraph @ 000000000346be80] No such filter: '[0:0]' Error initializing complex filters. Invalid argument
Is the original thread answer for non-audio mistaken? Or have I not exactly done what the original thread answer suggests?
