mlv_dump on Mac OSX

[marekk]

I'm trying to compile mlv_dump on Mac OSX. Make ends with this error:
mlv_dump.c:1456:34: error: no member named 'buffer' in 'struct raw_info'

I'm using this compiler: https://launchpad.net/gcc-arm-embedded/4.7/4.7-2013-q1-update/+download/gcc-arm-none-eabi-4_7-2013q1-20130313-mac.tar.bz2

Maybe someone know how to compile it sucessfully on Mac ?

[dmilligan]

For starters, unless you are somehow running Mac OSX  on an ARM processor, you shouldn't be using the ARM compiler (the ARM compiler is for ML, b/c the camera's processor is ARM, but mlv_dump is a computer utility, you need to use the compiler for your computer's architecture).  If you have xcode installed with command line tools, you should have a standard version of gcc and also llvm (not sure which versions of those, don't have my mac with me right now). You probably need to modify the makefile to point at the correct compiler for your computer. You might also have to find and download an appropriate version.

[marekk]

I've got xcode 5.0.1 with command line tools.

gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)
Target: x86_64-apple-darwin12.5.0
Thread model: posix

[dmilligan]

perhaps you need to install and use the "real" gcc compiler rather than apple's llvm version:
http://superuser.com/questions/517218/how-do-i-install-gcc-4-7-2-on-os-x-10-8

those instructions are a little old, I'd go for 4.8 rather than 4.7, but you get the idea.

Or maybe you need to look at the error message and propose a fix.

I installed gcc 4.7.3 and still the same error...

raw.h

Code: [Select]

#if INTPTR_MAX == INT32_MAX     // only works on 32-bit systems
    void* buffer;                   // points to image data
    #else
    uint32_t do_not_use_this;       // this can't work on 64-bit systems
    #endif
I'm trying to compile it on x64 system so there is no buffer..
added -m32 at the end of this line:
LV_CFLAGS=-DMLV_USE_LZMA -Wpadded -mno-ms-bitfields -O2 -Wall $(LFS_FLAGS) -I$(SRC_DIR) -std=c99

and now it ends with:

ld: warning: ignoring file lzma/lib7z.a, file was built for archive which is not the architecture being linked (i386): lzma/lib7z.a
Undefined symbols for architecture i386:
  "_LzmaCompress", referenced from:

ufffff finally it works..

1. I had to install gcc 4.7.3 (sudo port install gcc47 +universal; sudo port select --set gcc mp-gcc47; hash gcc)
2. Makefile:

MLV_CFLAGS=-DMLV_USE_LZMA -Wpadded -mno-ms-bitfields -O2 -Wall $(LFS_FLAGS) -I$(SRC_DIR) -std=c99 -m32

LZMA_CFLAGS=-c -O2 -Wall -c -m32

3. CpuArch.c from lzma lib has a bug as described at http://sourceforge.net/p/sevenzip/bugs/1338/
4. CpuArch.c replaced with http://sourceforge.net/p/sevenzip/bugs/_discuss/thread/ceab2abb/ab04/attachment/CpuArch.c

Great Job Marek, can you please post the compiled version here?

Hi,
how to use mlv_dump on Mac OS X
Thanks

[marekk]

you should to record a raw video using mlv_rec module, then you can convert *.MLV files to DNG or RAW file.

Hi,
As I try using mlv_dump I write "./desktop/folder/mlv_dump filename.MLV " into Terminal window, it answers:

" Mode of operation:
   - Input MLV file: 'M05-1620.MLV'
   - Verify file structure
[E] Failed to open file 'M05-1620.MLV' "

Where am I wrong?
Please can someone explain me what to do?
Thanks

[g3gg0]

tried passing the whole path to the file?

tried passing the whole path to the file?

Hint: you can drag and drop a file onto the termnial window to get the full path

Hi,
I tried but the answer is always the same:

Marekk, I'm trying to compile on OSX 10.6.8, however, have you come across these errors?

Compiling version 4.7.3 right now so I'll get back to the thread after I've played around with the new compiler.

Hi everyone and thanks for all what is being done !

I tried to convert .mlv on a mac running osx 10.9.1

I dropped mlv_dump followed by the .mlv onto terminal. Here is what I get :

 MLV Dumper v1.0

So Terminal says it's done, but it doesn't seem anything happens.

I am not a developer and when I use Terminal, my knowledge is very limited.

Tanks for your insight !

[g3gg0]

you have to specify what to dump.
open a command line and type mlv_dump --help
or use the GUI (MLVBrowseSharp)
