fix compiler error on Mac of missing endian.h

[chundongwang]

Originally if you compile untrunc on mac, you'll get track.cpp:28:10: fatal error: 'endian.h' file not found. But even if you switch to <machine/endian.h>, it'll still complain about file.cpp:74:12: error: use of undeclared identifier 'be32toh'.

So solution is to provide be32toh with OSSwapBigToHostInt32, and so on. For windows we might have to implement ourselves but I'll leave it to someone really needs windows support to implement this.

Sorry for the huge delay, I have removed the endian.h dependency and updated the avcodec api.

Would you mind gettin gthe latest version so I can merge the docs?

Hi! To get it compiled, i commented the includes for endian.h. Also i have to reference CoreFoundation and CoreVideo to fix some symbol references. This is the command line i've used on OSX 10.12.6

g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -I./libav-12.2 -L./libav-12.2/libavformat -lavformat -L./libav-12.2/libavcodec -lavcodec -L./libav-12.2/libavresample -lavresample -L./libav-12.2/libavutil -lavutil -lpthread -lz -framework CoreFoundation -framework CoreVideo -framework VideoDecodeAcceleration -lbz2

Hi, was the dependency on endian.h really removed? I still have to "sed -i.orig -e's:endian.h:machine/endian.h:' *cpp" to make it compile.

Hi, I get the track.cpp:46:10: fatal error: 'config.h' file not found after solving the endian.h dependency with mike402's "sed -i.orig -e's:endian.h:machine/endian.h:' *cpp".

Here is my folder for reference and fixing. https://drive.google.com/open?id=11Jr-KXLXR8y3AITcIKdW4CuwUj__ShIf
Thanks!

Used jmoleiro's suggestion for the compile command.

Yeah -definitely not working on Mac anymore.

track.cpp:197:12: error: out-of-line definition of 'getLength' does not match any declaration in 'Codec'
int Codec::getLength(unsigned char *start, int maxlength) {

track.cpp:385:59: error: no member named 'codec_name' in 'AVCodecContext'
throw string("Could not open codec: ") + codec.context->codec_name;

among a slew of warnings.
