Video Codec In Matlab
The video sample that was used to determine the video codec’s performance was foreman_qcif.y. It had the following attributes:
Resolution: 176X144 pixel, Number of Frames: 400, Total File Size: (176X144X400) bytes = 10,137,600 bytes Frame Rate: 30 fps
Video Bit rate was calculated using the following formula:
[PSNR] = main(sequence, d_sequence, bitfile, quality, frame, blkx, blky, searchrange, height, width)
sequence: input file (i.e. foreman_qcif.y)
d_sequence: output file (i.e. decoded_ foreman_qcif.y)
bitfile: this argument is a string that is used in naming the output bit files. For example, by inputting 'example_1', the encoded frame bitfiles will be named 'example_1.bit'. Note: avoid putting '.bit' at the end of this string since it is appended for you in the application.
