The proposed construction of video steganography was realized by embedding the secret image into the meaningful cover image of any type of video file using CABAC
Data is compressed much more efficiently with CABAC
than CAVLC; but CABAC
encoding needs much more processing power to drive it.
Evaluation and decision on modes contribute to CAVLC, CABAC
, and EXP-GOLOMB in a simplified way to address the data-handling constraints.
When the high profile video service is required, CABAC
is preferred over CAVLC because CABAC
achieves better compression efficiency.
As you can see in the screenshot of Sorenson Squeeze shown in Figure 4, there are two choices, CAVLC and CABAC
, with the latter available only when producing using the Main or High Profiles.
264, check to make sure that the vendor supports the baseline, main, and high profiles; enables CABAC
support; and, at the very least, lets you set options such as the number of sequential B-frames between I- and P-frames.
264, VP6, or VC-1), select a player (Flash, QuickTime, Windows Media, or Silverlight), or specify general encoding parameters such as resolution, data rate, or frame rate, not to mention advanced parameters such as variable bitrate encoding, B-frame interface, and CABAC
I encoded with the High Profile, CABAC
entropy encoding, and every "damn the encoding time, full quality ahead" option supported by Carbon Coder.
