hi_mpi_venc_request_idr

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Requests for an instantaneous decoding refresh (IDR) frame.

Ensure that a channel has been created. Otherwise, a failure is returned.
After an IDR frame request is received, if instant is 0, an IDR frame is encoded in the next frame as controlled by the frame rate controller; if instant is 1, an IDR frame is encoded instantly.
IDR frame requesting is applicable to H.264 and H.265 encoding.
Typically, the destination frame rate is the same as the source frame rate. Therefore, frame rate control has no impact on this API. Regardless of the setting of instant (either 0 or 1), an IDR frame is encoded on every call to this API. Note that too frequent calls to this API cause fluctuations in the frame rate and bit rate of the stream.
When the GOP mode is OT_VENC_GOP_MODE_SMART_P or B-frame mode, the request for the IDR frame takes effect after a delay.
