What is a decoder, which ones do I need, and where do I get them?
A combination of audio decoders and video decoders are required for you to watch live tv and recordings. In simplistic terms, decoders take compressed audio/video frames, and decompresses them into audio samples for sending to the speakers, or video frames for displaying on the screen.
NextPVR is a non-commerical application, and ships without any decoders installed, since these would cost $$$ for me to legally license and distribute. Instead, NextPVR will make use of decoders you already have on your system. Some of these are supplied with Windows, some come from other applications you have installed, some are downloaded from Internet sources.
Below is info on what decoders you need and recommendations, the TL;DR answer: install the LAV decoders from HERE, then go to the Settings->Decoders screen, and set everything to the LAV decoders
It depends on the country you're in, the television system you're using, and sometimes the device you use. If you don't have a decoder you require, NextPVR will tell you what type of decoder it's missing. Here are some example decoder requirements for common user groups:
| Aspect | Key Questions for Analyst | | :--- | :--- | | | Where can the enemy see my routes? Where can I place OPs? | | Cover & Concealment | Where can forces hide from direct/indirect fire? | | Obstacles | What natural (rivers, ridges) or man-made (mines, walls) obstacles exist? | | Key Terrain | Which single point (e.g., bridge, hill) gives a decisive advantage to whoever holds it? | | Avenues of Approach | What are the most likely corridors for enemy movement (air/ground)? |

NextPVR is a 32bit application so will only see 32bit decoders on the machine. It can't see 64bit decoders, so these will not be listed.
NextPVR's decoder settings only apply to Live TV, and the playback of .ts recordings. For playback of other file types, like .mkv/.mp4/.avi, it's left to Windows to decide what decoders etc are used during playback. Installing LAV from HERE will often resolve issues with playback of these other file types.
