A video encoding system balances memory usage to store interpolated image data with processing resource usage to interpolate image data without encoding quality degradation or with better encoding quality. This balance can be achieved by identifying and interpolating subregions of a reference image. Each...
Discover how to use AV Foundation and Video Toolbox to access hardware accelerated encoding and decoding services. Gain best practices...
stop() Stops encoding or decoding. release() Releases all resources. Normal Mode In normal mode, your application must continuously transmit data to the Codec instance during encoding and decoding. To use the encoder in normal mode, perform the following steps: Call createEncoder() to create a...
When paired, encoding and decoding enable efficient live video delivery under the constraints of your network. It's all well and good until you realize you don't really want every viewer to receive that 1080p60 video. Viewers watching the stream over limited network connections and on small sc...
First of all, let's review the theoretical knowledge of video encoding and decoding. video is composed of a series of pictures arranged in chronological order: 1) Each picture is a frame; 2) Each frame can be understood as a two-dimensional matrix; ...
There are disclosed various methods, apparatuses and computer program products for video encoding and decoding. In some embodiments for encoding a block of samples is obtained for motion prediction (). At least one translational base motion vector component for the block of samples is calculated by...
