It resets settings to recommended values for the most popular DirectShow filters and codecs it configures audio output settings it replaces your current settings with those from a previous backup it configures your chosen DirectShow splitters for the most common file extensions and the list does not end here. With a size of less than 1 MB, this tiny application not only finds and removes broken codecs or filters it clears the Windows icon cache, it re-registers base DirectShow filters, it backs up or restores setting and it repairs broken thumbnail settings.īroken thumbnail repairing is possible, regardless of the video formats on your computer, from AVI to MKV and from MPEG to WMV.Ĭodec Tweak Tool does complicated things fast so you don’t have to deal with them.

I do not want to make any additional changes on this laptop because it is needed in production shortly and I don't want to break it.What Codec Tweak Tool actually does is scanning the registry in order to detect broken references to codecs and filters, generating a detailed list of all the codecs and filters installed on your system, and enabling or disabling more than 200 codecs.Ĭodec Tweak Tool has a minimal interface, but its utility is undeniable, when you are dealing with some codec pack that is not working. After I rebooted the middle block changed to 'LAV Video Decoder' and the videos still play. This fixed the issue for me and the videos are now playing. This then reset all of the 'Preferred decoders' to 'Microsoft' so I went through and set them all back to 'USE MERIT'.īetween these two steps the GraphEdit was now displaying 'Video Renderer' in the final block, however the middle block was some Microsoft thing (Didn't take a screencap at this stage). Instead I hit the 'Re-register DirectShow filters from K-Lite Codec Pack' option in General>Fixes. Because I deploy to multiple machines I am hesitant to change the 'Video Renderer' string. I looked at the GraphEdit on the machine that wasn't working and saw that it was using 'Video Mixing Renderer 9' just like When I opened the Codec Tweak Tool the 'Re-register base Directshow Filters' was already checked.

Most have worked in the past however one wasn't working. In my case I do my development on a different machine and deploy applications to multiple other machines. I was having the same issue with 'failed to find the video renderer'.
