Method and apparatus adjusting a bitrate in real time, and server device

A method for adjusting a bitrate in real time, the method comprising:

• synchronizing frames across multiple threads in response to a bitrate adjusting instruction;
• obtaining parameters in a bitrate control logic to determine the bitrate, after the frames are synchronized;
• calculating the value of each parameter at the current bitrate as a current value;
• calculating a target value of each parameter at a target bitrate, according to a proportional relationship between the current bitrate and the target bitrate corresponding to the bitrate adjusting instruction and the current value of the corresponding parameter;
• modifying the value of each parameter to the target value corresponding thereto;
• and
• performing subsequent encoding to synchronization of the frames, using the value of each parameter modified.

An apparatus for adjusting a bitrate in real time, the apparatus comprising:

• at least one processor;
• and
• a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein execution of the instructions by the at least one processor causes the at least one processor to:
• synchronize frames across multiple threads in response to a bitrate adjusting instruction;
• obtain parameters in a bitrate control logic to determine the bitrate after the frames are synchronized, and calculate the value of each parameter at the current bitrate as a current value;
• calculate a target value of each parameter at a target bitrate according to a proportional relationship between the current bitrate and the target bitrate corresponding to the bitrate adjusting instruction and the current value of the corresponding parameter;
• modify the value of each parameter to the target value corresponding thereto;
• and
• perform subsequent encoding to synchronization of the frames, using the value of each parameter modified.

A non-transitory computer-readable storage medium storing executable instructions that, when executed by an apparatus for adjusting a bitrate in real time, cause the apparatus to:

• synchronize frames across multiple threads in response to a bitrate adjusting instruction;
• obtain parameters in a bitrate control logic to determine the bitrate after the frames are synchronized, and calculate the value of each parameter at the current bitrate as a current value;
• calculate a target value of each parameter at a target bitrate according to a proportional relationship between the current bitrate and the target bitrate corresponding to the bitrate adjusting instruction and the current value of the corresponding parameter;
• modify the value of each parameter to the target value corresponding thereto;
• and
• perform subsequent encoding to synchronization of the frames, using the value of each parameter modified.
