FFMPEG snimanje stereo sadržaja
1
Preview obiju komara (za kalibraciju). Dva cam ulaza i overlay (checkerboard) za provjeru prekpapanja.
ffmpeg -y -f dshow -video_size 640x480 -framerate 30 -pixel_format yuyv422 -video_device_number 0 -i video="Icatch(X) KV Series Null Device" -f dshow -video_size 640x480 -framerate 30 -pixel_format yuyv422 -video_device_number 1 -i video="Icatch(X) KV Series Null Device" -filter_complex blend=all_expr='if(eq(mod(X,2),mod(Y,2)),A,B)' -vcodec rawvideo -pix_fmt yuyv422 -f sdl "SDL output"

Paralelno spremanje inputa dviju kamera u dva file-a. Svakako prije treba utvrditi koja je desna, a koja lijeva kamera.
ffmpeg -y -f dshow -video_size 640x480 -framerate 30 -pixel_format yuyv422 -video_device_number 0 -i video="Icatch(X) KV Series Null Device" LEFT.mp4 | ffmpeg -y -f dshow -video_size 640x480 -framerate 30 -pixel_format yuyv422 -video_device_number 1 -i video="Icatch(X) KV Series Null Device" RIGHT.mp4
3
Konvertiranje dva videa (left/right view) u SBS video (framepacking)
ffmpeg -i LEFT.mp4 -i RIGHT.mp4 -filter_complex framepack=sbs OUTPUT.mp4
4
Konvertanje SBS (full res) u anaglyph red/cyan
ffmpeg -i OUTPUT.mp4 -vf stereo3d=sbsl:arcd OUTPUT_ANAGLYPH.mp4
