Release decode resources
#include <img.h>
int img_decode_finish( img_codec_t codec,
io_stream_t * input,
uintptr_t * decode_data );
- codec
- The handle of the codec that was used to decode.
- input
- A pointer to an input stream for the image data.
- decode_data
- The address of the uintptr_t that was used for img_decode_begin() and img_decode_frame().
img
This function finalizes the decode process and releases resources allocated during a decoding session. You should call this function after you have finished decoding a series of frames, to release any resources that the decoder may have allocated in association with those frames.
|
You do not need to decode all the frames in a stream, but you should always follow up with img_decode_finish() when you have decoded the frames you are interested in to avoid potential memory leaks. |
- IMG_ERR_OK
- Success.
- IMG_ERR_NOTIMPL
- The codec doesn't support decoding (Currently, all codecs shipped with the Neutrino image library support decoding).
- Other
- Any other code that a decoder's begin() function may pass back to flag an error (see img_errno.h for a list of defined errors).
