ffmpeg -i input.mp4 - filter_complex \    "[0:v]split=4[v0][v1][v2][v3]; \     [v0]trim=start_frame=0:end_frame=1,loop=90:1:0,setpts=n/frame_rate/tb[0v]; \     [v1]trim=start_frame=1:end_frame=301,loop=90:1:299,setpts=n/frame_rate/tb[1v]; \     [v2]trim=start_frame=301:end_frame=601,loop=90:1:299,setpts=n/frame_rate/tb[2v]; \     [v3]trim=start_frame=601:end_frame=900,loop=90:1:298,setpts=n/frame_rate/tb[3v]; \     aevalsrc=0:d=3[0a]; \     [0:a]asplit=3[a1][a2][a3]; \     [a1]atrim=0:10,asetpts=n/sr/tb[1a]; \     [a2]atrim=10:20,asetpts=n/sr/tb[2a]; \     [a3]atrim=20:30,asetpts=n/sr/tb[3a]; \     [0v][0a][1v][1a][2v][2a][3v][3a]concat=n=4:v=1:a=1[v][a]" \    -map "[v]" -map "[a]" outva.mp4

i : unable find suitable output format 'pipe:' pipe:: invalid argument
