◆ esp_h264_dec_close()

esp_h264_err_t esp_h264_dec_close ( esp_h264_dec_handle_t dec )

This function closes the H.264 decoder instance specified by dec

Parameters

[in] dec A pointer to the H.264 decoder instance

Returns

esp_h264_err_t esp_h264_dec_del ( esp_h264_dec_handle_t dec )

This function is used to delete an H.264 decoder.

Parameters

[in] dec A pointer to the H.264 decoder instance

Returns

esp_h264_err_t esp_h264_dec_open ( esp_h264_dec_handle_t dec )

This function opens an H.264 decoder in stream.

Parameters

[in] dec A pointer to the H.264 decoder instance

Returns

This function performs decoding of H.264 video frames.

Parameters

[in]	dec	A pointer to the H.264 decoder instance
[in]	in_frame	A pointer to encoded input frame
	[in/out]	out_frame A pointer to store decoded output frame. The `out_frame->outbuf` will store an image data address after decoding. This address will be re-used in `esp_h264_dec_process`. Users, ensure to retrieve the data in the address promptly. If the NALU is not related to image data like SPS, PPS, etc., `out_frame->out_size` will return 0.

Returns
