Hello everyone,
I'm trying to use lavc on an embedded platform to solve what is in fact
a very simple problem. I need lavc to decode a single JPEG image into a
user-supplied buffer.
The image might be "large" e.g. 4000x3000 (resulting in an uncompressed
size of 36 MB). The user-supplied buffer is allocated through some
platform-specific code (not malloc).
Ideally, lavc would provide something like the following
int decode_jpeg(char *filename, uint8_t *buf, int bufsiz);
where decode_jpeg() would open the JPEG file named by filename, decode
it to an RGB bitmap (3 bytes per pixel) and store the result in buf (up
to a limit of bufsiz).
The result would be the number of octets written to buf, or some
negative value in case of error.
Do you know of some such function in lavc or lavf?
