Member Typedef Documentation

◆ BitRateCalculator

using ts::ModulationArgs::BitRateCalculator = bool (*)(BitRate& bitrate, const ModulationArgs& args)

bool ts::ModulationArgs::allow_emulator_pipes = false

inherited

Allow the tuner emulator to run processes using pipes. The TSDuck tuner emulator uses XML files to describe transport streams in an emulated network. The content of a transport stream can be read from a file or from the output of a piped command. By default, running commands through the emulator is disabled for security reasons. This option authorizes the creation of processes. Applies to: TSDuck tuner emulator.
