rdrender 1 August 2017 Linux Audio Manual rdrender Render a Rivendell log as a single audio file Fred Gleason fredg@paravelsystems.com Application Author rdrender OUTPUT-OPTS RENDERING-OPTS AUDIO-OPTS logname rdrender1 can be used to render an existing Rivendell log as a single audio file, thus enabling playback of the rendered content independently of Rivendell. Three different types of options can be given to rdrender1: Output, which affect the outputs of the program, Rendering, which control how a log is virtually "played" and Audio, which control the format of the resulting audio file. Each group of options is documented separately below. --to-cart=cartnum:cutnum Save the rendered log to cut number cutnum in cart number cartnum. Both cart and cut must already exist. This option is mutually exclusive with the --to-file option, below. --to-file=filename Save the rendered log to the filename file. This option is mutually exclusive with the --to-cart option, above. --verbose Be verbose. Among other things, this will cause rdrender1 to print a disposition for each log event encountered to standard error. Exactly one --to-cart or --to-file option must be specified. --first-line=lineno Start rendering the log at line lineno. This option is mutually exclusive with the --first-time option, below. --first-time=HH:MM:SS Start rendering the log at the event having a hard-start time of HH:MM:SS. This option is mutually exclusive with the --first-line option, above. --ignore-stops Treat any STOP transitions encountered as if they were PLAY transitions. If not given, a STOP transition will cause rendering of the log to be terminated at the point where the STOP was encountered. --last-line=lineno Stop rendering the log at line lineno-1. This option is mutually exclusive with the --last-time option, below. --last-time=HH:MM:SS Stop rendering the log at the event having a hard-start time of HH:MM:SS. This option is mutually exclusive with the --last-line option, above. --start-time=HH:MM:SS Render the log as if it had been started at a time of HH:MM:SS (useful for ensuring that dayparted carts play as expected). If not given, the current system time will be used. --bitrate=rate Specify the bitrate to use, in rate bits per second. Default value is 256000 bits/sec. This setting is meaningful only when used with the MP2 or MP3 formats. --channels=chans Use chans channels in the output file. If not given, 2 channels (stereo) will be used. --format=format Specify the file and audio encoding format to be used. The following values for format are recognized: FLAC Free Lossless Audio Codec (.flac) MP2 MPEG-1 Layer 2 (.mp2) MP3 MPEG-1 Layer 3 (.mp3) PCM16 PCM16 audio in a WAV file format (.wav) PCM24 PCM24 audio in a WAV file format (.wav) VORBIS OggVorbis (.ogg) Default value is PCM16. --normalization-level=level Peak normalize the audio to level dBFS. Default value is 0, which will disable peak normalization. --quality=qual Specify the quality level to use, in the range -1 through 10, inclusive. Default value is 3. This setting is meaningful only when used with the VORBIS format. --samplerate=rate Specify the sample rate to use, in rate samples per second. Default value is the sample rate configured in System Settings in rdadmin1. rdrender1 makes no attempt to interpret hard-start time values beyond allowing them to be used to flag the start and end of rendering. (See the --first-time and --last-time rendering options). Due to limitations inherent in the 32 bit Broadcast Wave File format used in Rivendell's audio store, the maximum length of the rendered log is limited to appoximately three hours for stereo and six hours for mono when using the --to-cart option.
