Feeds images to the encoder for encoding. This API is asynchronous.

aclError aclvencSendFrame(aclvencChannelDesc *channelDesc,
acldvppPicDesc *input,
void *reserve,
aclvencFrameConfig *config,
void *userdata)

Parameter	Input/Output	Description
channelDesc	Input	Pointer to the channel description. Must be the same as the channelDesc argument passed to the aclvencCreateChannel call. Specify the video encoding callback function in the channel description.
input	Input	Pointer to the input image description. The user needs to allocate input buffer in advance. Call acldvppCreatePicDesc to create an image description, and call the acldvppSetPicDesc series to set the image description (including the width and height). The input image format is subject to the format set in the channel description. The acldvppSetPicDescFormat call to set the input image format is invalid. For details about the input resolution and format restrictions, see Functions and Restrictions.
reserve	Input	Reserved.
config	Input	Pointer to the single-frame configuration.
userdata	Input	Pointer to the user-defined data.

0 on success; else, failure. For details, see aclError.

Ensure that a channel has been created. Otherwise, an error code is returned.
It is not allowed to send an empty stream packet with eos = 0 (stream length is 0 or stream address is empty).
When an empty image with eos = 1 is sent, the current encoding ends.
During encoding, the input buffer can be released only after the result is obtained from the aclvencCallback function.
