img_decode_finish()
QNX SDP8.0Image Library ReferenceAPIDeveloperProgramming
Release decode resources
Synopsis:
#include <img/img.h>
int img_decode_finish( img_codec_t codec,
io_stream_t *input,
uintptr_t *decode_data );
Arguments:
- 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().
Library:
libimg
Use the -l img option to qcc to link against this library.
Description:
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.
Note:
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.
Returns:
- IMG_ERR_OK
- Success.
- IMG_ERR_NOTIMPL
- The codec doesn't provide an implementation for this function.
- 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).
