Abstract
According to certain aspects, an apparatus for coding video data includes a memory for storing the video data and a processor. The memory includes a buffer. The processor is configured to receive the video data to be coded. The processor is further configured to determine a Lagrangian parameter for a coding mode based at least in part on a bit rate of the coding mode and a fullness of the buffer.

An apparatus for coding video data, comprising:
- a memory for storing the video data, the memory including a buffer;
- and
- a hardware processor operationally coupled to the memory and configured to:
- receive the video data to be coded;
- and
- determine a Lagrangian parameter for a coding mode based at least in part on a bit rate ratio of a current block and an extent of a fullness of the buffer, wherein the bit rate ratio is based on a number of bits for coding the current block using the coding mode divided by a number of bits for coding the current block without the application of any compression.
A method of coding video data, comprising:
- storing the video data in a memory, the memory including a buffer;
- receiving the video data to be coded;
- and
- determining a Lagrangian parameter for a coding mode based at least in part on a bit rate of ratio of a current block and an extent of a fullness of the buffer, wherein the bit rate ratio is based on a number of bits for coding the current block using the coding mode divided by a number of bits for coding the current block without the application of any compression.
A non-transitory computer readable medium comprising instructions that when executed on a processor comprising computer hardware cause the processor to:
- store the video data in a memory, the memory including a buffer;
- receive the video data to be coded;
- and
- determine a Lagrangian parameter for a coding mode based at least in part on a bit rate ratio of a current block and an extent of a fullness of the buffer, wherein the bit ratio is base on a number of bits for coding the current block using the coding mode divided by a number of bits for coding the current block without the application of any compression.
