videoIO on Mac OS X

[lvdmaaten]

I'm trying to get videoIO to run on Mac OS 10.5.7 (Intel) using GCC 4.0.1 and Matlab 7.6.

I removed all old versions of ffmpeg and installed the last version from SVN as described in the installation instructions. Then, I had to make some minor code edits in order to get everything to compile: e.g., globally replaced sighandler_t into sig_t and added some missing casts from int to PointFormat. Then I added the following in arch2gccarch.pl:

} elsif ($arch eq "-maci") { # Mac Intel
    print "-m32";

I think I should use m32 here right, and not m64? The only problem I could not get fixed is a problem with the script ffmpeg-config-internal.pl not finding my ffmpeg libraries:

./ffmpeg-config-internal.pl --libs
Could not find ffmpeg's avformat library

I thought I could circumvent this problem by manually editing the Makefile to get the right settings:

FFMPEG_LINK        := -L /usr/local/lib/libavcodec.dylib -L /usr/local/lib/libavformat.dylib -L /usr/local/lib/libswscale.dylib -L /usr/local/lib/libavutil.dylib

Everything then actually compiles and links, but videoIO crashes while running the tests, presumably because it cannot resolve the links to the ffmpeg libraries:

??? Error using ==> feval
Unexpected Standard exception from MEX file.
What() is:basic_string::_S_construct NULL not valid

Error in ==> videoReader.videoReader at 151
  vr.handle = feval(vr.plugin, 'open',vr.handle, ...

I tried to resolve this problem by static linking in ffmpeg by changing the Makefile to:

FFMPEG_LINK        := -L /usr/local/lib/libavcodec.a -L /usr/local/lib/libavformat.a -L /usr/local/lib/libswscale.a -L /usr/local/lib/libavutil.a

But then I get a strange error while linking:

ld: absolute addressing (perhaps -mdynamic-no-pic) used in _put_signed_pixels_clamped_mmx from /usr/local/lib/libavcodec.a(dsputil_mmx.o) not allowed in slidable image. Use '-read_only_relocs suppress' to enable text relocs
collect2: ld returned 1 exit status

    mex: link of ' "videoReader_ffmpegDirect.mexmaci"' failed.

I guess the best way to go is to try and get the ./ffmpeg-config-internal.pl to actually recognize my ffmpeg installation. Any thoughts on how to get this done? Or any other thoughts on how to proceed?

[Gerald Dalley]

I'm glad to see a Mac user daring enough to try to get this to work.  I've never used a Mac for more than a few minutes, so I'll have to make some guesses.  For the -m32 versus -m64, you'll need to know whether you have 32-bit or 64-bit Matlab (and you'll want to have the corresponding bitness for ffmpeg if you want to keep life easy).  Try running the videoIoSysInfo script and look at the "arch" variable.  Note that the current build system tries to be smart enough to even let you use 32-bit ffmpeg with 64-bit Matlab, under limited circumstances.

It looks like .dylib is Mac's equivalent to .so, based on what you have listed above.  In that case, edit ffmpeg-config-internal.pl and look for ("so","a") in findUsrLib.  Add a "dylib" option to the beginning of the list (so it's preferred over static libs).

If you're going to modify FFMPEG_LINK directly, use -L for directories and -l for actual libraries.  For example, to use the dylibs, use "-L/usr/local/lib -lavcodec -lavformat -lswscale". 

The reason it's crashing with the dylibs is because the C++ standard library isn't getting linked (based on the error message you included...basic_string is a core part of C++'s standard lib).  On some platforms, it's linked by default, but apparently it's not linked for you by default for some reason.  ffmpeg-config-internal.pl actually does try hard to hunt down all the required dependencies.  On linux, this is handled via the 'findUsrLib($option,0, "", "z","dl","m");' line and the "`nm ..." calls.  We may need to expand the set of libraries being searched.  We'll discuss that option once we get ffmpeg-config-internal.pl to recognize the ffmpeg libs. 

As for the static linking problem, you should be able to statically link, but you've just bumped into an annoying problem with static libs on 64-bit machines.  The whole binary being built must make a decision on whether to be "relocatable" or not.  Being relocatable adds a lot of flexibility, but it reserves one CPU register for the relocation address (thus possible reducing performance).  We need to be relocatable for some technical reasons.  If you want to statically link, you'll need to rebuild ffmpeg's static libs with relocation turned on.  With gcc on linux, this is done by adding -fPIC to CXX_FLAGS and C_FLAGS. 

My preference would be to get ffmpeg-config-internal.pl to work, as you suggest.  That way others can benefit too. 

Well, actually my absolute preference would be to redo the build system to use autotools, but that's a long-term and low-priority job...

[lvdmaaten]

Ok, I edited the ffmpeg-config-internal.pl to hunt for dylibs, and it works now. It was checking whether the architecture was correct in findUsrLib, and the check was only implemented for Linux. Also, it assumed folders like /usr/lib32 and /usr/lib64, which are simply called /usr/lib on OS X. Here's the results of running ffmpeg-config-internal.pl:

Macintosh-10:videoIO laurens$ ./ffmpeg-config-internal.pl --libs
-L/usr/local/lib -L/usr/lib -lavformat -lavcodec -lavutil -lswscale -lz -ldl -lm
Macintosh-10:videoIO laurens$ ./ffmpeg-config-internal.pl --staticlibs
/usr/local/lib/libavformat.a /usr/local/lib/libavcodec.a /usr/local/lib/libavutil.a /usr/local/lib/libswscale.a /usr/local/lib/libz.a
Macintosh-10:videoIO laurens$ ./ffmpeg-config-internal.pl --arch
-maci
Macintosh-10:videoIO laurens$ ./ffmpeg-config-internal.pl --cflags
-I/usr/local/include -I/usr/include -m32
Macintosh-10:videoIO laurens$ ./ffmpeg-config-internal.pl --rpath
/usr/local/lib:/usr/lib

That looks all fine to me!
Then, I edited to Makefile to not explicitly specify the architecture to ffmpeg-config-internal.pl, as the maci architecture is not implemented there (so it calls ffmpeg-config-internal.pl as I do in the example above).

But now, when I clean and rebuild, the linker quits without proper error message:

Macintosh-10:videoIO laurens$ make

collect2: ld terminated with signal 11 [Segmentation fault]

    mex: link of ' "echoDirect.mexmaci"' failed.

I manually tried to compile with -m64 and -arch i386 instead of -m32 inside CXXFLAGS, but that did not help much. Any thoughts on what's next?

[Gerald Dalley]

It looks like we're making some good progress.  After we're all done, it would be nice to have a final copy of your modified ffmpeg-config-internal.pl.

I did some poking around on the web for the collect2 error message.  The consensus for such error messages is that one of 3 things is happening: (1) there's a hardware bug (unlikely, IMHO), (2) there's a bug in the version of ld you're using (seems extremely likely), or (3) the files supplied to ld are bad and a bug in ld's error checking is causing the segfault (seems to be the most likely).  Is there a way you can upgrade your binutils package?  It seems that 2.18 is much more stable than 2.16.

A few other things to do: (1) run videoIoSysInfo and send me the videoIoSysInfo.txt file that it creates.  Often this helps me find tricky problems.  (2)  Take the failed call to mex and run it directly in your shell, but add a "-v" option.  Post the results.  This will give us some extra details about what exactly is being done.

I was about to suggest that you try buildVideoIO inside Matlab, but it looks like you already have done so.  Sometimes this makes things better, sometimes it makes them worse.  Matlab ships with its own version of gcc, etc.  I wouldn't be surprised if it has its own copy of ld.  It would still be interesting to investigate some of the issues I mentioned above so we can come up with a robust solution.  I'll answer the buildVideoIO post next.

[lvdmaaten]

Curiously, using buildVideoIO in Matlab instead of make in the Terminal resolved that problem! Everything now compiled successfully.

However, when running testAll I get the same error as before:

??? Error using ==> feval
Unexpected Standard exception from MEX file.
What() is:basic_string::_S_construct NULL not valid

Error in ==> videoReader.videoReader at 151
  vr.handle = feval(vr.plugin, 'open',vr.handle, ...

Any thoughts on how to get the standard library to be linked in?

[Gerald Dalley]

Answer to the buildVideoIO post...

It looks like Matlab's version of gcc and/or binutils (ld) is working better than Apple's, but the std c++ library is not being linked. 

Quick thing to try... run each of these:
    standardTestBattery('ffmpegPopen2')
    standardTestBattery('ffmpegDirect')
Do both result in the problem you're seeing?

The current problem is most likely due to one of two things.  (1) the standard c++ library may not be linked for some odd reason or (2) it is linked, but LD_LIBRARY_PATH may not be working correctly.  Problem #2 is the more likely.  Matlab tends to do some crazy stuff with the LD_LIBRARY_PATH. 

Try adding /usr/local/lib to LD_LIBRARY_PATH before launching Matlab.  If you use bash, this can be done via:
    export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
Try running the tests again.

If that fails, we'll try a quick hack: add "-lstdc++" to the linker options, at the end (order is important).  At least on Linux, that's the

If that fails, then it's time to try to hunt down the actual library where basic_string is defined.  At least on Linux, this can be done by hunting through likely directories using the "nm" and "objdump" commands.  I can go into more detail if we have to resort to this method.
   

[lvdmaaten]

It turns out my LD_LIBRARY_PATH was empty indeed. I simply set it in Matlab: setenv('LD_LIBRARY_PATH', '/usr/local/lib');

Both standardTestBatteries now terminate with a different error. The standardTestBattery('ffmpegDirect') is actually running for quite some time, claiming it runs doFullRead and doMultiFullReadTest on all movies, but when it gets to doMultiFullReadTestOnAllLoadables it exits. The standardTestBattery('ffmpegOpen2') exit pretty much right away, also at doMultiFullReadTestOnAllLoadables. Here's the error message I get:

So it seems like one of the two plugins is pretty much working; at least it reads in frames. What's the difference with the ffmpegPopen2-plugin? Any speed differences / different features / etc.? Is the EOF error somehow fixable?

[Gerald Dalley]

Did you run videoIoSysInfo after the setenv call, or before it?

Don't worry about the "is not fully compatible" messages right now.  It's important information to know as a user, but it's presented poorly in the current version.  I'm slowly working on presenting it better.  The basic point is that the underlying codecs are not required to be correct...they can do things like guess the right file location when you ask it to seek to a specific frame.  They can also decode the exact same same frame differently depending on things like past seeks and its guess as to how much of a hurry you are in.

Did you get any error message from the ffmpegDirect plugin?  It would be very helpful.  If it's crashing and killing Matlab, you might be able to run Matlab without a GUI so you can still see the messages.  On linux, you can launch Matlab via "matlab --nodesktop"

I'll have to try to figure out why videoIoSysInfo is dying.  Do you know what version of Matlab you have? 

The two plugins have exactly the same backend, but they are built differently and have a different communication protocol with Matlab.  ffmpegDirect is built the way one would normally build a MEX function.  Matlab calls a specially-named C++ function called "mexFunction", which eventually calls the ffmpeg libraries.  Everything is bound up together in a shared library, the MEX function (i.e. the *.mex* files on a Mac are really *.dylib files with renamed extensions).  ffmpegDirect is technically the most efficient way to run videoIO.

I created the ffmpegPopen2 plugins a while ago because I kept running into a few issues.  First, from time to time, ffmpeg has been buggy and could crash an application, especially when one uses the subversion version instead of the official releases.  The other problem is that ffmpeg and libraries it relies on are built with the system's gcc, but Matlab was built with its own version of gcc.  Sometimes this causes nasty conflicts when you try to load a shared library built with one version of gcc into an application built with a different version of gcc that's incompatible (gcc makes breaking changes every few years).  In both cases, a solution is to have a very thin shared library act as the MEX function and then build a separate full-fledged executable to do the real work.  The MEX function launches the backend application and communicates with it through a pair of pipes.  Pipes are basically fake file handles...the MEX function writes to a fake file handle and the backend reads commands from that handle whenever they show up.  popen2 is the system call to start an executable and grab the pair of pipes (one for reading, one for writing).  If a bug in the backend (either my fault or ffmpeg's) causes a crash, then the server app dies, but Matlab keeps on ticking.  Also, the two versions of gcc basically only need to be compatible enough to successfully call popen2 and handle read and write operations properly.  The downsides of the popen2 architecture are that it's slightly slower (but not enough to notice) and when the backend crashes, it's hard to get error messages out of it...the backend sends them, but sometimes it dies and shuts down the pipes before the MEX function has a chance to read them.

[lvdmaaten]

I see. Debugging the ffmpegPopen2 sounds horrible indeed; I remember using pipes once to communicate between C++ and JavaScript: big mess!

Well, I can at least use the direct implementation for now (I need speed anyway)...

I did the videoIoSysInfo after the setenv. I use Matlab 7.6 (R2008a). The ffmpegDirect run outputs the following:

Apparently the ffmpegDirect test-battery does use ffmpegPopen2 at some point?!

Hello lvdmaaten,

It seems that you have worked out how to get VideoIO running on a MAC OSx. Would it be possible to get your changed files in order to install VideoIO?

You also refer to &quot;FFMPEG SVN as described in the installation instructions&quot; Which installation instructions do you refer to?
Do you really need SVN version or is ffmpegx also good?

I used videoIO on a PC and that was very usefull. But I switched to MAC and hope to get it running there as well!

Thank

[lvdmaaten]

It's a long time ago since I did this, so I don't really remember the details. Anyway… there's a copy of my full videoIO folder with MACI binaries on http://ict.ewi.tudelft.nl/~lvandermaaten/videoIO.zip (46 MB).

I guess you need a working installation of ffmpegx in order for it to work, and you need to make sure that Matlab can find it. I installed ffmpegx in /usr/local/lib and I do this in order to use videoIO:

<pre>
addpath('videoIO');
setenv('LD_LIBRARY_PATH', '/usr/local/lib');
vr = videoReader(base_folder, 'ffmpegDirect');
info = get(vr);
no_frames = info.numFrames;
for i=1:no_frames
   next(vr);
   imshow(getframe(vr));
   drawnow;
end
</pre>

Hope that helps!

[SnowJeb]

Thank for the code.
It works to some extend, but not quite.
It might be that I have Snow Leopard installed?

So I try a again:

Trying to colpile VideoIO I run into several problems. 1 I dealed with in the makelfile.
But still I run into trouble. See the error message below. Does this ring a bell?

Undefined symbols:
  "_fdopen$UNIX2003",…

Thank in advance,
Jeroen

I altered the makefile a bit:
For some reason I had to explicitly include a libriray. I suppose there is a better way to do this.

[georg ogris]

I also ran into similar problems when compiling VideoIO for IntelMac.
Finally, I managed to get it all compiled.

I collected any changes I made in a diff file (see next post).
testAll.m run into some errors, which is probably due to the modifications I made in some cpp files.
(pretty dump changes, just to get it compiled.)

Anyway, reading videos into matlab works fine. Approximately 7 times faster than with the
internal Matlab VideoReader class.

great work! thanks!

Warning: Frame 85 from the concatenated source looks different from frame 85 from "intersection147.25fps.xvid.avi"
(randomly selected frame #943).  This is either because the decoder jumped to the wrong frame (imprecise seeking)
and/or it used a low-quality decode to make the random seek faster.
