About the Stereoscopic 3D Support in the Daum Potplayer

September 10th, 2012 · 7 Comments · Other S3D Tech

Potplayer is yet another free software video player coming from Korea, much like the GOM Player or the KMPlayer, in fact Potplayer is very similar to KMPlayer in many aspects including the fact that the player comes with built-in codecs to support all of the most common video and audio codecs out of the box. And much like the other two Korean players mentioned above, Daum Potplayer also has some stereoscopic 3D support built-in and that is what interests me the most…

The Potplayer has built-in support for displaying 2D subtitles properly when playing back stereoscopic 3D videos with it, however this only works for 3D videos in Side by Side or Top & Bottom format. The options is available in the right-click quick menu as well as in the player options. Of course you get the 2D subtitles properly displayed on top of 3D video, but the subtitles are put at screen depth level and you cannot adjust their position in 3D space. For more flexibility you will need to go for something like the ffdshow subtitles filter for the playback of 2D subtitles over 3D video files.

What is more interesting in the Potplayer is the ability to use a predefined set of pixels shaders to convert 3D videos from Side by Side or Top & Bottom to anaglyph 3D format (Green-Magenta or Red-Cyan) and to watch a 3D version of 3D videos. This and the 2D subtitles support for 3D videos is intended to be used for 3D video playback on 3D HDTVs and the only thing in that aspect that is kind of missing here is the support for Row Interleaved output for passive 3D HDTVs. Another thing that is missing and might be useful in terms of stereoscopic 3D support is a software pageflipping mode that could be useful for people with 3D DLP projectors. So there is more to be desired in terms of stereoscopic 3D support from the Portplayer, though with the use of pixel shaders (if you know how to write the needed code) it is possible to extend the functionality of the player. Nevertheless Daum Potplayer could be useful for some people willing to play not only stereo 3D videos, but various 2D videos as well, so if you still haven’t tried it you might check it out.

x3D-Player is a Another Free Stereoscopic 3D Video Player

July 25th, 2012 · 5 Comments · General 3D News

One thing that we are kind of still missing in the world of stereoscopic 3D video is a really powerful and feature rich, yet fast and simple to be used stereoscopic 3D video player available for free similar to Media Player Classic for 2D video for example. The closest thing currently available is the Stereoscopic Player by Peter Wimmer, however it is a commercial product and it still lacks some useful features that we are used to having in most 2D video players such as the MPC. So it is always a good thing to see more stereoscopic 3D video players as in reality there aren’t that many. So here comes the x3D-Player, a simple and free solution, that while still lacking even some basic features looks like a promising thing to watch as it develops.

The x3D-Player is being developed by Cristea Aurel Ionut from Romania and so far things look good, though the player does not yet support all of the most popular stereoscopic 3D input and output formats. Currently you can use the x3D-Player to open 2D clips or 3D videos in either Side by Side or Over/Under format and you can output them in anaglyph 3D format (Blue/Yellow, Red/Cyan or Green/Megenta), show only the left or right frame (2D mode) or output them in Side by Side or Over/Under format (real-time conversion from the input). You can also open real-time video capture devices, although this may not work with 3D input sources. But you have a

What is still missing for example is the ability to resize in real-time the video window of the player, or when switching to full screen to not show the taskbar (unless it is set to auto-hide). There is a timeline that you can use for navigation, but it does not auto-hide in fullscreen mode and you cannot yet control the volume level, there also isn’t a right-click menu for switching the output format etc. when in full screen mode and lots more. So in general there is a lot of work to be done in order to make the player a serious stereoscopic 3D video playback solution, but it is always to have more alternatives and hopefully the development of the player will continue further.

Download the x3D-Player here as the developer’s website currently has some issues…

3DVplayer, a Chinese 3D Video Player for Android-based 3D Smartphones

February 25th, 2012 · 10 Comments · Other S3D Tech

If you have used the LG Optimus 3D (Thrill 4G) or HTC Evo 3D smartphones or even own one yourself you might not be too happy with the built-in 3D video player that comes with these devices. Unfortunately there aren’t many alternatives available, at least on the Android Marketplace, but I’ve stumbled on one interesting Chinese player called 3DVplayer. The official website of the player is available only in Chinese, but the player itself also comes with English translation of the interface. You need to download it and install it manually on your device, follow the link below to get the APK, then transfer it to your 3D-capable smartphone and install it through a file manager.

The player comes with two modes of operation – one for playing back online 3D videos and a mode to play stereoscopic 3D videos that are available on the device, the online mode brings you a library with some apparently free to watch 3D clips. It works well with Side by Side video stored on the device and the network playback may be a bit slow as apparently the 3D videos are stored somewhere in China and your connection to them may be a bit slow. Still the 3DVplayer is worth checking out if you own an Android-based 3D-capable smartphone such as the Optimus 3D or the HTC Evo.
