How to get ffmpeg to run on OSX

ffmpeg is a so called command line tool for audio/video file conversion and processing.
It's an open source project and parts of (depending on its configuration) it are not allowed to be redistributed in binary form without also providing the full source code.

For now, I suggest you take the time to download some free tools and source codes and to start the so called build process on your Mac on your own.
To build ffmpeg configured with all the parts needed to serve as trueColor3D's processing engine, you need

- XCode from the Apple MacAppStore
- The MacPorts project http://www.macports.org/
- FFMpeg from it's source code repository

You may need to launch the Terminal.app and type in and launch some commands.

1) Install XCode (should be free for Lion and just $3.99 for SnowLeopard).
2) Download the port command from the MacPort project and follow the instruction to build it with the gcc compiler tha came with xcode.
3) type in sudo port install ffmpeg and enter your admin/root password to download and build and install the ffmpeg program.

trueColor3D now also runs on OSX






First trueColor3D only ran on Windows, because it strongly depended on the AviSynth audio/video scripting environment that is tricky to run on non-Windows machines.


I started to reprogram many of the conversions from AviSynth to only use video filter commands in ffmpeg.
This is the first result.


On OSX, the following old/new stereo-layouts are supported :

Youtube: my3D, iPad (over/under 1080p)
Vimeo: my3D, iPad (over/under), PC (over/under)
home use: my3D, iPad (iTunes), iPad (AirVideo)


Download version 0.95 from my DropBox :
Source code only (v0.95),
Windows 32-bit binary (v0.94),
OSX 32-bit binary (v0.95)

ADRI EV stereoscopic music video for iPad and other tablets

Watch this on a tablet device locked to landscape, but oriented to portrait using one of the over/under viewers (KMQ, jpsOneEye or BerezinOneEye).

This video was created with my open source tool trueColor3D

New way to upload 3-D for iPad to vimeo

Me and many viewers don't like the way, vimeo degrades videos with a width below 1280 to SD quality bitrate. For normal widescreen content that's fine, but not for our special portrait over/under layout. I experimented in the past with rotation, scale to bypass this, but either vimeo degraded the content or the iPad refuses to play it, becaue it was regarded too HiRes.
Today I found a new way by omitting black borders on the top and buttom and by rotating to the right. So, clips originating on 16:9 can now be uploaded as 1280 x 1040. Viewed with an orientation locked to landscape and held as portrait, this results in 1040 x 586 per eye and a 108px gap. And this layout fits both the vimeo and the iOS size restrictions.
I hope to soon reupload in the new format, but for GRilli3D fans there is still no alternative to view from "Download".

New tags for Youtube 3D

Andrew Murchie's overview of the new Youtube 3D tagging.


So now, you can simply upload a trueColor3D made over/under (aka iPad3D) clip of 768x1024 to Youtube and tag it with
yt3d:enable=RonL

This way, it plays on all FLASH-enabled browsers in selectable 3D modes, also plays on iPad using the KMQ or compatible viewers and can be used with StereoPlayer and NVidia shutter glasses.


What's left ?
Okay - for smartphone support you still need an undistorted side-by-side version like the my3D with 1280x480px, also made with trueColor3D.

And for glasses-free viewing on iPad, we still need the GRilli3D1024 layout.
