Hello,
.. ups, silly me. I forgot to
#include <h264_stream.h>
in the ".sip" file. Sorry about that.
But that still leaves me with one of the original questions, because,
now, when compiling I get:
error: invalid conversion from âchar*' to âuint8_t* {aka unsigned char*}'

Sampsa

Hello,
An absolute beginners question in wrapping C libraries with SIP:
The library header file ("h264_stream.h") has the following:
-------------------
#ifndef _H264_STREAM_H
#define _H264_STREAM_H 1
#include <stdint.h>
#include <stdio.h>
#include <assert.h>
....
....
....
int find_nal_unit(uint8_t* buf, int size, int* nal_start, int* nal_end);
...
...
...
----------------------
Here is my "h264_stream.sip":
---------------------
%Module h264_stream
%UnitCode
#include <stdint.h>
#include <stdio.h>
#include <assert.h>
%End
// int find_nal_unit(uint8_t* buf, int size, int* nal_start, int* nal_end);
int find_nal_unit(char* buf, int size, int* nal_start, int* nal_end);
// int find_nal_unit(int* buf, int size, int* nal_start, int* nal_end);
-------------------------
.. those commented lines were things I tried, but as I want a byte
buffer, so "char*" makes the most sense, right?
After ..
-------------
sip -c . h264_stream.sip
python configure.py
make
-------------
.. I get:
------------
./siph264_streamcmodule.cpp:37:49: error: âfind_nal_unit' was not
declared in this scope
sipRes = find_nal_unit(a0,a1,&a2,&a3);
^
make: *** [siph264_streamcmodule.o] Error 1
-------------
What is going on?
Also, I'd like to use the data type "uint8_t", i.e.
int find_nal_unit(uint8_t* buf, int size, int* nal_start, int* nal_end);
.. but that does not seem to be possible. Any way to achieve this (or
does it make any difference?) ?
I can see that "stdint" etc. are correctly included in
"siph264_streamcmodule.cpp"
Regards,
Sampsa (a sip newbie)
