gsvideo with (slightly) better OSX support
Jan 29^th, 2009, 5:35pm

Hello,

I just released a new version of gsvideo that doesn't require macports or any other additional install on OSX, so it should be much easier to use (same thing on windows, actually). However, Processing needs to be started from the terminal, but this will hopefully solved soon. For more details and downloads follow this link:

Update: The terminal thing can be avoided by editing the file ~/.MacOSX/environment.plist. Details in the link above.

But please be careful when following this method, since you can break other applications (and even the whole system) when modifying the environment.plist file (specially if typos are introduced in it). Create a backup of your environment.plist file if it already exists before making any changes, and don't replace its entire contents with the sample I posted on sourceforge example, just add the DYLD_LIBRARY_PATH variable.

Hopefully, this hack won't be needed in the future as we find a better way to install gsvideo on OSX.

checking in on any possible progress including OSX GStreamer plugin for capture, osxvideosrc, in gsvideo-mac

i'm headed to get a new vid card for my windows xp in the morning to solve the problems i was having there, but i'd rather use gsgl on mac. not trying to bug, windows just gives me anxiety...

thanks.

I recently did some progress on the mac front. I compiled gstreamer from scratch using the latest packages from macports, and it seems to work nicely with gsvideo. The capture plugin osxvideosrc runs ok (although it is still in alpha stage), and GSMovieMaker should work as well. However, I need to do some more tweaks and run a couple of additional tests. If I have some available time, I'll upload a preliminary version to my website so you can start testing it.

Ok, I have a version of gsvideo + gstreamer binaries that you can use... not finished yet, but I think is worthwhile giving a try. You need to download the following two files:

http://users.design.ucla.edu/~acolubri/test/gstreamer/macosx/gsvideo-20090311.zip

http://users.design.ucla.edu/~acolubri/test/gstreamer/macosx/opt.zip

The first is just the gsvideo library package, which goes into Processing's library folder.

The second zip file contains gstreamer binaries, and it should be unzipped into the root folder of the main hard drive.

The included examples require a little hack in order to work properly, which is the following: before running any gsvideo function, add the following line:

GSVideo.forceGlobalGstreamer = true;

For example, you could add this line right after the size() function, i.e.:

Code:


void setup() {
  size(640, 480);
  GSVideo.forceGlobalGstreamer = true;

  mov = new GSMovie(...

This ensures that gsvideo finds the gstreamer binaries in /opt/local. This hack won't be needed once the new version of gsvideo is "officially" released.

I also run some benchmarks with different video formats. Strangely enough, the fps is lower than the windows version. But the CPU utilization is also smaller...

DV/DVCPRO 720x480, 29.5fps with sound (in a mov container): plays at ~20fps with ~32% cpu utilization

XVID4 720x480, 29.5fps with sound (in an avi container): plays at ~22fps with ~27% cpu utilization

H264 1280x544, 23.98 fps with sound (in a mov container): plays at ~19fps with ~40% cpu utilization

XVID4 1280x544, 23.98 fps with sound (in an avi container): plays at ~19fps with ~40% cpu utilization

DV/LAVC 720x576, 25.00 fps with sound (in an avi container): plays at ~19fps with ~27% cpu utilization

Test system: MacPro with Dual-Core Intel Xeon @ 2.66Ghz, 2GB RAM
Operating system: Mac OSX 10.5.5

My impression is that these binaries of gstreamer should run in OSX 10.4 as well, but I haven't tested this.

thanks for the update!!!
i followed all your directions and i do not get any errors. the sketch seems to open, but i am only getting a blank screen. I tried using livepocky example thru gsvid and it opens with blank screen too. this example works fine when i use it thru processing normal lib. any thoughts. I am dropping the "GSVideo.forceGlobalGstreamer = true;" in appropriate spots.

i am using:
MAC OSX 10.5.6
MacbookPro
2.6 GHz Intel

Hello.

What about the playback and moviemaker examples. Do the work ok?

Unfortunately, the capture gstreamer plugin I'm currently using in GSVideo (osxvideosrc) is still in a very preliminary stage. Among other things, it doesn't allow to use a resolution different from 640x480. This could be one reason for the problem...

THANK YOU!!! it was the resolution that i had 960 x 540. i ordered a new vid card for my windows xp, so i'll let you know how both machines are running. really thank you!

ac Full Member Offline Posts: 237	Re: gsvideo with (slightly) better OSX support Reply #10 - Mar 14^th, 2009, 6:47pm Great. Keep me posted. I wonder if anyone has tried these gstreamer binaries on OSX 10.4 or earlier... they should work, but not sure.

vuhec YaBB Newbies Offline Posts: 13	Re: gsvideo with (slightly) better OSX support Reply #13 - Mar 20^th, 2009, 5:10am just tried on MACOSX 10.5 2Ghz PowerPC G5 and not working here either. so, looks like only intel?

ac Full Member Offline Posts: 237	Re: gsvideo with (slightly) better OSX support Reply #14 - Mar 20^th, 2009, 6:08am It's quite likely. I need to check how to compile universal version of the libraries with macports.
