jpeg_encoder_process() function
Process encoding of JPEG data using the specified encoder engine. This function processes the encoding of JPEG data using the provided encoder engine and configuration. It takes an input buffer containing the raw image data, performs encoding based on the configuration settings, and outputs the compressed bitstream.
Syntax
esp_err_t jpeg_encoder_process(jpeg_encoder_handle_t encoder_engine,
const jpeg_encode_cfg_t *encode_cfg,
const uint8_t *encode_inbuf,
uint32_t inbuf_size,
uint8_t *encode_outbuf,
uint32_t outbuf_size,
uint32_t *out_size);
Return value
- ESP_OK: JPEG encoder process successfully. - ESP_ERR_INVALID_ARG: JPEG encoder process failed because of invalid argument. - ESP_ERR_TIMEOUT: JPEG encoder process timeout.
