PROB: LuxRiot DVR may be unable to show video due to conflict with FFDSHOW software
The information applies to:
- LuxRiot up to 1.6.2
Symptoms
With FFDSHOW (DirectShow and VFW codec for decoding/encoding many video and audio formats) installed, LuxRiot DVR Client might fail to show some video streams due to software conflict.
Note that FFDSHOW might be installed as a part of other software distributions such as:
- Media players
- Codec packs
- Multimedia software
Description
FFDSHOW software registers itself as a priority DirectShow filter, intercepts LuxRiot’s video stream and fails to decode it. Typically, LuxRiot DVR Client would show gray filled image or, in GDI mode, display a message that it is unable to decode video due to absence of JPEG codec.
FFDSHOW might also affect presentation of MJPG encoded video (the codec is typically being used to encode video grabbed using ComArt boards).
Resolution
In order to workaround the conflict it is required to either uninstall FFDSHOW package or disable its codecs that conflict with LuxRiot software.
To pop up FFDSHOW configuration dialog, use Run… menu item in Start Menu and start the following command:
rundll32 %windir%\system32\ffdshow\ffdshow.ax,configure
and disable the codecs MJPG, SVQ1, SVQ3 as shown below:
Click Apply to commit the changes. LuxRiot DVR Client will need to be restarted for the changes to have effect.
Starting next release of LuxRiot it will also be possible to adjust priority of LuxRiot’s codec and switch codec FOURCC codecs to allow LuxRiot and other software (like FFDSHOW) operate simultaneously.
