Application-based screen recording

A screen recording apparatus, comprising:

• processing circuitry configured to:
• execute a recording application process corresponding to an application, the recording application process including a primary rendering thread, a secondary rendering thread, and an encoding thread, the secondary rendering thread and the encoding thread being enabled based on a screen recording operation;
• copy, through the primary rendering thread, rendering data stored in a back buffer of the primary rendering thread to a bridge buffer, a shared texture identifier being bound to the bridge buffer;
• obtain, through the secondary rendering thread, the rendering data from the bridge buffer based on the shared texture identifier;
• draw the rendering data onto an input rendering surface provided by the encoding thread to generate an output rendering surface;
• and
• encode, through the encoding thread, the output rendering surface to generate video frame data.

A non-transitory computer-readable storage medium storing instructions which, when executed by a processor, cause the processor to perform:

• executing a recording application process corresponding to an application, the recording application process including a primary rendering thread, a secondary rendering thread, and an encoding thread, the secondary rendering thread and the encoding thread being enabled based on a screen recording operation;
• copying, through the primary rendering thread, rendering data stored in a back buffer of the primary rendering thread to a bridge buffer, a shared texture identifier being bound to the bridge buffer;
• obtaining, through the secondary rendering thread, the rendering data from the bridge buffer based on the shared texture identifier;
• drawing the rendering data onto an input rendering surface provided by the encoding thread to generate an output rendering surface;
• and
• encoding, through the encoding thread, the output rendering surface to generate video frame data.
