Hi All, I have 3 USB cameras streaming video at a specific resolution. I am trying to merge the videos together using hstack and display using ffplay.
This is the command I am using: ffmpeg -f dshow -pix_fmt uyvy422 -video_size 1280x2160 -i video="CAM_0" -f dshow -pix_fmt uyvy422 -video_size 1280x2160 -i video="CAM_1" -f dshow -pix_fmt uyvy422 -video_size 1280x2160 -i video="CAM_2" -filter_complex hstack=3 -f nut - | ffplay - There is a special case in this system. The USB Camera system will only start video stream only when 3 cameras are enabled (or started by ffmpeg). However when I am using the above command, ffmpeg starts CAM_0 and waits for data. As a result CAM_1 and CAM_2 are not started and video stream does not start. Is there any way where I can start all 3 inputs simultaneously using ffmpeg and then merge them together using hstack? Thanks! _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
