Variants

Buffer

buffer information

Provides information about the frame's buffer. This event is sent once as soon as the frame is created.

The client should then create a buffer with the provided attributes, and send a "copy" request.

Fields of Buffer

format: u32width: u32height: u32stride: u32
Flags

frame flags

Provides flags about the frame. This event is sent once before the "ready" event.

Fields of Flags

flags: Flags
Ready

indicates frame is available for reading

Called as soon as the frame is copied, indicating it is available for reading. This event includes the time at which presentation happened at.

The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples, each component being an unsigned 32-bit value. Whole seconds are in tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo, and the additional fractional part in tv_nsec as nanoseconds. Hence, for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part may have an arbitrary offset at start.

After receiving this event, the client should destroy the object.

Fields of Ready

tv_sec_hi: u32tv_sec_lo: u32tv_nsec: u32
Failed

frame copy failed

This event indicates that the attempted frame copy has failed.

After receiving this event, the client should destroy the object.
