I am having trouble getting this command right: ffmpeg \ -loop 1 -framerate 30 -t 41.6 -i filler640480.jpg -i 79c11008-e36c-492d- b776-a06d4cc6c0c0.mp4 -y \ -loop 1 -framerate 30 -t 5.408 -i filler640480.jpg -i 68a23b17-04b6- 4484-b9d8-77fddbe3689c.mp4 -y \ -f lavfi -t 0.1 -i anullsrc=channel_layout=mono:sample_rate=48000 \ -filter_complex " [0:v]setsar=1[v0];[1:v]setsar=1[v1];[v0][1:a][v1][2:a]concat=n=4:v=1:a=1" -vsync 2 1985-grid.mp4
Both of the MP4 files are audio only. I am adding an image to combine the audion files into a video. Here is the error I am getting: Stream specifier ':a' in filtergraph description [0:v]setsar=1[v0];[1:v]setsar=1[v1];[v0][1:a][v1][2:a]concat=n=4:v=1:a=1 matches no streams. It looks like I was able to get it working with 1 loop. This command seems to run fine: ffmpeg \ -loop 1 -framerate 30 -t 1.4 -i filler640480.jpg -i 1e4eb136-0fe3-4e05- 93ae-6e2fa47e2b53.mp4 -y \ -f lavfi -t 0.1 -i anullsrc=channel_layout=mono:sample_rate=48000 \ -filter_complex " [0:v]setsar=1[v0];[v0][1:a]concat=n=2:v=1:a=1" -vsync 2 093-grid.mp4 Any help would greatly be appreciated.
