"Introduction to VR"--360 Panorama video

This chapter uses an earlier Unity OC plugin to implement a 360 panorama video, and you can switch video content at will by using a different path configuration. This eliminates the process of packaging multiple times, easy to use.
Of course, you can spend 40 of knives to buy one.

This one still listens to expensive.
Or make a free bar!!!
After packing, no password is available:
OC version 0.8.0 cloud disk address:

OC version 0.4.4 cloud disk address:

I. Resource requirements

Simply make a 360 panoramic video with the resources you need:
AVPro Windows Media2.9.0 Unity Plugin
：
Http://pan.baidu.com/s/1bz7pc6

0.4.4runtime required to install OC:

Second, make a 360 VR video 1. Import Plugins

Import Avpro Windows Media2.9.0 Plugin

Figure 6

Find the precast body he gives such as:

Figure 7

Then select the video file:

Figure 8

2. Decoder installation

If you run this time, you will get an error, as follows
According to the error:
For MP4 files-need an MP4 splitter such as Haali Media splitter or GDCL.

If you are interested in further understanding, you can look at the following address:

http://haali.su/mkv/

To download the required decoder directly here:
：

Then install:

Figure 11

Then load the load test again:
If you see the following, the decoder installation is successful

3. Set up video load configuration and run settings

First, you need to block the original main camera and then add the OC camera preform

Figure 13

Then, add the well-written configuration file code:

Figure 15

Finally, be careful not to tick the virtual Reality supported option because we are using the lower version of the Ocruntime plugin.

Figure 14

Of course, I also packaged the test of OC 0.8.0 Runtime, possibly relative to the 0.4.4 version, OC caused by the possibility of a crash is smaller. This is not a detailed test, just believe in unity Embedding and OC version upgrade optimization capabilities.
The packaged file will also be given the download link address later.

Third, use the configuration file to package and modify the video content at any time

Directly modify the Loadmovie function in AVProWindowsMediaMovie.cs.

BOOL Allownativeformat = (_colourformat! = Colourformat. RGBA32);String filePath = GetFilePath ();String FilePath = ConfigFile. Cconfig. Vediofullpathname;if (_movieplayer. Startvideo(FilePath, allownativeformat, _colourformat = = Colourformat. YCbCr_HD, _allowaudio, _useaudiodelay, _useaudiomixer, _usedisplaysync, _ignoreflips, _texturefiltermode, _textureWrapMode ) {if (_allowaudio) {_movieplayer. Volume= _volume;_movieplayer. Audiobalance= _audiobalance;} _movieplayer. Loop= _loop;if (autoPlay) {_movieplayer. Play();}} else

In fact, the only thing to modify is the video loading path, that's all.
Just change:

//string filePath = GetFilePath();        string filePath = ConfigFile.Cconfig.VediofullPathName;

That's all you can do.

Script for the configuration file:

usingUnityengine;usingSystem;usingSystem.IO;usingSystem.Xml.Serialization; Public classConfigfile:monobehaviour { Public StaticConfigFile Instance {Private Set;Get; } Public StaticClientconfigreference Cconfig;voidAwake () {Try{Readconfigfile (Application.streamingassetspath +"/configfile.xml"); }Catch(Exception ex) {Debug.logerror ("Read XML Failed! "+ ex.        Message); }    }voidReadconfigfile (stringFilePath) {Try{FileStream fs =NewFileStream (FilePath, FileMode.Open, FileAccess.Read); XmlSerializer xs =NewXmlSerializer (typeof(clientconfigreference)); Cconfig = xs. Deserialize (FS) asClientconfigreference; Fs.            Dispose (); Debug.Log ("ConfigFile:"+ FilePath); }Catch(Exception ex) {Debug.logerror ("Read configfile Failed! "+ ex.        Message); }    }}//Configure class Public classclientconfigreference{ Public stringVediofullpathname;}

This only needs to be mounted in the scene and does not require any action.

Interested in self-study.

Five, after packaging run test: 1. First use of the starry sky:

Resources can be downloaded at the following address of the article:
Look at the beautiful stars:

Figure 16

Figure 17

Figure 18

Figure 19

As you can see, this is a monocular effect, because the use of the Dapeng helmet, the effect of using the copy screen, the resolution is not correct, but in the direct run, does not affect the use and experience.

2. Look at the beauty.

By toggling the configuration file

 <VediofullPathName>H:\Unity\UnitySay\360Video\360Demo\360VedioTest\Assets\StreamingAssets\猫耳娘SEASON 2.mp4</VediofullPathName>

To switch the video content.

Figure 21

Figure 22

Figure 23

Because the texture clarity is not very high, this needs to be improved.
There is also the use of the old version of OC, so it may crash. The crash log is as follows:

That's it.

So, as you just said, you can use a later version of OC's 0.8.0 version of the packaged version.

After the project is downloaded, you need to put the video file under Streamingassets, and then use the configuration file Configfile.xml to use it.

Project release address: After packaging, add a new video file directly under Streamingassets, and then use the configuration file Configfile.xml to use it. It's so simple and fast.
