This format is also used in mythbackend logs of scheduling activity (with -v schedule), and is particularly useful when obtaining schedule data with -testsched. The -printsched command line option prints out upcoming scheduled recordings. Need to add backend-specific troubleshooting help here, or at least link to Troubleshooting Interpreting -printsched Output Mythbackend uses the logging routines shared by the rest of MythTV, and the command line options defined there can be used to control where and what debugging information is logged. Work on defining the Myth Protocol is being performed on this Wiki. The mythbackend and mythfrontend communicate using their own Myth Protocol.
In modern versions, typing mythbackend -help also worksĪnd may provide more information on the option selected. To get an accurate list of options for the installed version of mythbackend, If remotely mounted, network performance should be considered as there will be considerable traffic on the network as recordings are stored and retreived by the backend process. The backend can use local HardWare/ File Storage or have it mounted from another system. There is no requirement for direct user interaction with the backend. Commercial Detection can be distributed across multiple backends, and other machines running mythjobqueue, thereby spreading the load of that process. A machine that does not have any tuners attached can store and serve content by running mythmediaserver instead of mythbackend. Each backend can have any number of tuners. This is especially true for scheduling as the master backend will determine the best distribution of programs across all available tuners. This backend is responsible for coordinating the activities of the other backends known as slaves. This is usually the first backend installed on a system. One backend process is designated as the master backend. The backend process interacts with the Database primarily.Īs with the mythfrontend, there can be multiple backends.
The backend process (mythbackend) is the portion of the system that handles the Video capture cards as well as Scheduling Recordings on those cards, Commercial Detection, and transcoding.
