Data Fields | |
struct spa_buffer * | buffer |
the spa buffer | |
void * | user_data |
user data attached to the buffer. | |
uint64_t | size |
This field is set by the user and the sum of all queued buffers is returned in the time info. | |
uint64_t | requested |
For playback streams, this field contains the suggested amount of data to provide. | |
uint64_t | time |
For capture streams, this field contains the cycle time in nanoseconds when this buffer was queued in the stream. | |
a buffer structure obtained from pw_stream_dequeue_buffer().
The size of this structure can grow as more fields are added in the future
struct spa_buffer* pw_buffer::buffer |
the spa buffer
void* pw_buffer::user_data |
user data attached to the buffer.
The user of the stream can set custom data associated with the buffer, typically in the add_buffer event. Any cleanup should be performed in the remove_buffer event. The user data is returned unmodified each time a buffer is dequeued.
uint64_t pw_buffer::size |
This field is set by the user and the sum of all queued buffers is returned in the time info.
For audio, it is advised to use the number of frames in the buffer for this field.
uint64_t pw_buffer::requested |
For playback streams, this field contains the suggested amount of data to provide.
For audio streams this will be the amount of frames required by the resampler. This field is 0 when no suggestion is provided. Since 0.3.49
uint64_t pw_buffer::time |
For capture streams, this field contains the cycle time in nanoseconds when this buffer was queued in the stream.
It can be compared against the pw_time values or pw_stream_get_nsec() Since 1.0.5
