Recently I wrote about bino, a stereoscopic video player that is usable with linux and also supports quad buffered stereo. In the meanwhile the versions 0.9.1 and 0.9.2 have been released. The new version includes multithreading to read, decode, and display video data in parallel, for better performance and some bugfixes.

Bino still does not work properly with linux, at least it still does not display anything on my gentoo box. The patch for bino, I provided here, does not work anymore.

Problems

At least on my gentoo box bino failed to display anything. When starting bino  it failed with a window popping up:

Cannot set GL context format

The reason for this was the same as before. Bino was requesting an alpha visual, which did not succeed. I have not seen the point in requiring an alpha visual for bino, so I just removed this. You may download the patch from here: [download#60]

Addon: The patch is only necessary when the X server does not provide an alpha visual, which may i.e. be the case when using only 16 bits of colour  depth.

Getting things to work

Download Bino from here: bino-0.9.2.tar.xy and extract it.

tar -xf bino-0.9.2.tar.xz

Afterwards apply my patches and compile Bino.

cd bino-0.9.2

patch -p0 < bino-0.9.2-quad-buffered-stereo.patch

./configure

make

make install

The Gentoo way

For gentoo users here is my overlay including the ebuild: [download#62] Download the modified overlay (it includes the patches) and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

Then emerge bino and enjoy viewing your 3d movies again.

One year ago I provided a patch for mplayer which included support for quad-buffered stereo, enabling mplayer to display stereoscopic movies. In the meanwhile mplayer-1.0_rc4_p20101114 arrived in portage. As before with the original patch from Stuart Levy, my one does not work anymore due to some changes in mplayers gl2 driver. So I had to modify the patch again to work again with newer mplayer versions. You may download the updated patch from here:

[download#54]

The patch should work at least with nvidia quadro boards, probably with some others. It can be used with CRT and generic shutter glasses or HMDs like the Vusix VR920. Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

The Gentoo way

For Gentoo users I again modified the mplayer ebuild from portage to include the patch. The modified ebuild is available here:

[download#53]

The older ebuild and patch are still available on mygnu.de.

To use the ebuild it just copy it to /usr/local/portage/media-video/mplayer and copy the the patch to the “/usr/local/portage/media-video/mplayer/files” directory. You probably have to create these directories. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc4_p20101114-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY=”/usr/local/portage”

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy the experience in the 3rd dimension again.

Last year I wrote about bino, a stereoscopic video player that is usable with linux and also supports quad buffered stereo. In the meanwhile the versions 0.8 and 0.8.1 have been released. Thanks  for your work, Martin. The new versions contain some bug fixes and the following new features:

• Adjustable ghostbusting to reduce crosstalk artifacts.
• Parallax adjustment.
• Mouse-based seeking.
• Initial support for choosing an audio stream.
• Improved compatibility with many video types.

Bino still does not work properly with linux, at least it does not display anything on my gentoo box. The good news is that my patch for bino, I provided here, still works.

The Gentoo way

For gentoo users here is my overlay including the ebuild: [download#52] Download the overlay (it includes the patch) and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

A while ago I updated the stereocopic mplayer patch to work again with newer mplayer versions. This patch worked to display side by side stereo movies in quad buffered stereo mode but it did not enable mplayer to display stereo videos consisting of two separate video streams for the right and the left eye like those produced with Fujifilm Real 3D cameras.  A player capable of displaying these files and many other stereoscopic movie formats is bino. I recognized that bino is also capable of displaying a single video stream in quad buffered stereo mode. For a future version it would be really nice to have it calculating a 3D version of the stream on the fly and displaying this fake stereo video. There are some algorithms known that are capable of doing this calculation. It should be possible to do this in parallel on the GPU, so processing power should not be the problem… Of course such a fake stereo video cannot have the quality of a real stereo one, but it may be the only possibility to watch ones favorite movie in stereo.

Problems

At least on my gentoo box bino failed to display anything. When requesting quad buffered stereo (bino -o stereo) it failed with:

bino: [err] display does not support stereo mode

When trying to start bino without quad buffered stereo it failed with:

bino: [err] cannot set GL context format

The reason for this was found quickly. Bino was requesting an alpha visual, which did not succeed. I have not seen the point in requiring an alpha visual for bino, so I just removed this. You may download the patch from here: [download#51]

Current patches for can be found here.

Getting things to work

Download Bino from here: bino-0.7.tar.xy and extract it.

tar -xf bino-0.7.tar.xz

Afterwards apply my patch and compile Bino.

cd bino-0.7

patch -p0 < bino-0.7-quad-buffered-stereo.patch

./configure

make

make install

The Gentoo way

For gentoo users here is my overlay including the ebuild: [download#50] Download the modified overlay (it includes the patch) and extract it in /usr/local/portage. Be sure to include the following line in your /etc/make.conf:

PORTDIR_OVERLAY=”/usr/local/portage”

Then emerge bino and enjoy viewing your 3d movies.

One year ago I provided a gentoo ebuild for mplayer which included support for quad-buffered stereo, enabling mplayer to display stereoscopic movies like the great movie Avatar3D I watched in cinema today. To learn more about the movie look here and here. Sadly the patch I referenced there does not apply over newer mplayer versions. So I had to modify the original patch from Stuart Levy to work again with newer mplayer versions. You may download the updated patch from here:

[download#35]

New version available!

The patch should work at least with nvidia quadro boards, probably with some others. It can be used with CRT and generic shutter glasses or HMDs like the Vusix VR920. Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

For Gentoo users I also modified the mplayer ebuild from portage to include the patch. The modified ebuild is available here:

[download#36]

New version available!

The older ebuild is still available on mygnu.de.

To use the ebuild it just copy it to /usr/local/portage/media-video/mplayer and copy the the patch to the “/usr/local/portage/media-video/mplayer/files” directory.  You probably have to create these directories. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc4_p20091026-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY=”/usr/local/portage”

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy the experience in the 3rd dimension again.

Experimenting with my VR920 3D stereo glasses I found a patch to enable stereoscopic support in mplayer (thanks to Stuart Levy). With this patch I can now watch 3D movies on my eyewear under linux. Let me tell you, it’s a really cool experience.

The patch should work at least with nvidia quadro boards, probably with some others. It can also be used with CRT and generic shutter glasses. You can download the patch from here:

mplayer-stereoscopic.patch

Some stereoscopic sample movies for trying it out can be found on www.3d.wep.dk.

For Gentoo users I modified the mplayer ebuild to include the patch. Download from here:

[download#2]

To use it just copy the mplayer subtree from the portage tree to /usr/local/portage/media-video/mplayer and remove the ebuilds. Copy the new ebuild to that directory and the patch to the “files” directory. Then run

ebuild /usr/local/portage/media-video/mplayer/mplayer-1.0_rc2_p28058-r1.ebuild digest

Be sure to include the following line in your /etc/make.conf.

PORTDIR_OVERLAY="/usr/local/portage"

Then just re-emerge mplayer.

Now start mplayer with -vo gl2:stereo and enjoy a new experience in the 3rd dimension.

Addon: Updated modified ebuild for the new version in portage tree:

[download#4]
