V264 Codec

An interesting development in the V264 Codec saga!

If you havn’t read it yet, its worth reading the first encounter with the V264 Codec.

It turns out that the V264 Codec belongs to Verint. A Video Surveillance Solutions company whose codecs over the years have given me hours of fun!

To start off with, if you are greeted with an AVI utilising the V264 codec, you can still deal with it using the method detailed in the original post. This method means you do not have to install the codec. It would be handy for a quick review prior to going over to a virtual machine or dedicated PC where the codec is installed.

Why would you need to install the codec if you can view it already… well, installing the codec registers a special directshow filter that reads the date/time information embedded in the avi and displays it over the video.

Lets take a look!

First off, to actually get the codec, you need to register. It took about 2 hours for my registration email and hyperlink to come through. It’s lucky that you can play the footage without the codec to start with.

The Codec I downloaded was named VerintVideoSolutionsCodecs_6.4.951.exe

I don’t install any propriatary codecs into may main machines – far too many conflicts. This is getting even worse with various Video Management Suites containing codecs for various IP cameras that they have partnered with.

Over to my virtual PC and before installing I took a snapshot using whatchanged. This will help me identify what the codec install is actually doing. Time to install…

Firstly, after installation, it is shown within installed programs as Ver. 62.0.7918.

Secondly, the whatchanged result revealed the newly installed files:

C:\Windows\System32\Audio.dll
C:\Windows\System32\axaacdec.dll
C:\Windows\System32\AxisHTTPMPSrcFilter.ax
C:\Windows\System32\AxisMediaViewer.dll
C:\Windows\System32\AxisMediaViewer.tlh
C:\Windows\System32\AxisRTPSrcFilter.ax
C:\Windows\System32\LRXHcodec.dll
C:\Windows\System32\LrxTextOV.ax
C:\Windows\System32\LrxYV12.dll
C:\Windows\System32\mpg4c32.dll
C:\Windows\System32\TelenorCom.dll
C:\Windows\System32\TJPEGCodec.dll
C:\Windows\System32\Verint.VideoSolutions.Media.TransportDecoders.dll
C:\Windows\System32\VerintVFWcodecs.dll
C:\Windows\System32\WaveT2.dll
C:\Windows\System32\WavLor.dll
C:\Windows\System32\WMV9VCM.DLL

Playing the video file now in Windows Media Player produces not only immediate playback but, it reveals the camera number, the camera name and the date and time. These details are within an overlay along the bottom of the footage.

Reviewing the filter graph identifies that it’s the file LrxTextOV.ax which enables this display. It has some properties to assist in overlay location that may assist the viewer.

Lrx, I presume stands for Loronix. This is another name whose codecs have to be handled with care. They have, in the past, caused a few conflicts with other software so be careful.

The conclusion to all of this is that, as stated before, it is possible to deal with the footage very quickly and neatly, without the codec BUT, in order to get the date and time information – you have to intall the Codec Filter.

Wouldn’t it be nice if Verint supplied a date / time extractor tool to put the information into a standard subtitle format such as .smi or .ssa. I have emailed them and if they respond I will update the post.

As always, I hope the information helps….

The story continues….
