Function Documentation

int av_lzo1x_decode ( void out,
int outlen,
const void in,
int inlen 
)

Decodes LZO 1x compressed data.

Parameters
outoutput buffer
outlensize of output buffer, number of bytes left are returned here
ininput buffer
inlensize of input buffer, number of bytes left are returned here
Returns
0 on success, otherwise a combination of the error flags above

Make sure all buffers are appropriately padded, in must provide AV_LZO_INPUT_PADDING, out must provide AV_LZO_OUTPUT_PADDING additional bytes.
