Wrapper around inflateInit().
It initializes the fields that zlib requires to be initialized before inflateInit(). In case of error it also returns an error message to the provided logctx; in any case, it sets zstream->inited to indicate whether inflateInit() succeeded.

void ff_inflate_end | ( | FFZStream * | zstream | ) |
Wrapper around inflateEnd().
It calls inflateEnd() iff zstream->inited is set and resets zstream->inited. It is therefore safe to be called even if ff_inflate_init() has never been called on it (or errored out) provided that the FFZStream (or just FFZStream.inited) has been zeroed.

int ff_deflate_init | ( | FFZStream * | zstream, |
int | level, | ||
void * | logctx | ||

Wrapper around deflateInit().
It works analogously to ff_inflate_init().

void ff_deflate_end | ( | FFZStream * | zstream | ) |
Wrapper around deflateEnd().
It works analogously to ff_inflate_end().
Referenced by cleanup(), encode_end(), and png_enc_close().
