51 of the input videos in the new room, such that the | |
52 right-most part of the video has is put side-by-side | |
53 with the left-most part of the video, and analogously | |
54 for the other sides. | |
55 .SH REQUIREMENTS | |
56 .B blind-extend | |
57 requires enough free memory to load two full frames into | |
58 memory, one of the size of the source video's frames, | |
59 and one of the size of the target video's frames. A frame | |
60 requires 32 bytes per pixel it contains. | |
61 .B blind-extend | |
62 has not been optimised for memory usage, but instead | |
63 for code simplicity. | |
