AXIS Media Control - MPEG-4 Tab
MPEG-4 Tab
This tab sets the advanced properties for MPEG-4 video processing and default video decoder.
Video Processing
Decode only key frames - By default, AXIS Media Control decodes as many MPEG-4 video frames as possible given the
capabilities and performance of the computer. To decrease the amount of CPU capacity used for video processing, it is possible
to only decode key frames. This will, however, greatly reduce the quality of the video being displayed. For an explanation of
different types of MPEG frames, please refer to the MPEG standards.
Allow frame dropping - This is the default setting that enables the MPEG-4 Video Decoder to drop frames if rendering falls
behind.
Deblocking filter - De-blocking enhances image quality by smoothing the sharp edges between different sub-image blocks in
MPEG-4, but it requires a higher CPU load.
Note: To use Allow frame dropping and Deblocking filter requires that you install or upgrade the AXIS MPEG-4 Video Decoder to version
2.2.0.0 or higher. You will be notified about the need to update the decoder when you try to enable these features.
Default Video Decoder
The MPEG-4 video decoder can be used to view standard MPEG-4 streams and files produced by other sources. This decoder
may, however, conflict with other MPEG-4 applications already installed in the target computer, e.g., XVID, DIVX6 players. Use
the buttons on this tab to attempt to resolve conflicts, or to set this decoder as the default for viewing MPEG-4 video content.
