Options in this section define file and server outputs and other outputs generated by the command line.
-o Output File -sg Output Server -pid Process ID File
Each of these options are described in detail below.
Output Filename or directory -o
The output filename or directory name if multiple input (batch encoding). Required when input is device but optional for file inputs (-i). For batch (more than one input) each input filename is used to generate the respective output filename. If a directory name and a single input file the output file name is auto-generated from the input filename and file is written to the directory specified. If directory and multiple input files specified, then all files are written to the output directory. If output directory does not exist, it is created. If a file exists with the requested output filename, the existing file is backed up immediately following the merge process to a filename based on the input filename with "_archNNN" inserted before the file extension where NNN is the next available integer (e.g. movie_arch001.rm). If the output file size reaches 4 GB (limit of RealMedia file format) the output file is automatically rolled and a new file is started. The new file is appended with a number (e.g. movie1.rm). On Linux 2.0.x kernels the output file is rolled at 2 GB to respect default kernel limitations. This option may be called multiple times. Each time this option is used on the command line a new active destination is added to the job. If relative paths provided, the location is relative to the current working directory. See CROSS-PLATFORM FILE PATHS section below for valid cross platform file paths.
Default:
No default for device input. Auto-generated for file input.
Values:
Any valid filename with path or directory.
Example:
-o C:\Windows\Desktop\movie.rm
-o /home/johndoe/commercialbreak.rm
-o
C:\Movies
Output Server -sg
Settings required for encoding to RealServer G2 through 8.01. The special delimiters (@ : /) are not allowed except as noted. May be called multiple times - each time a new active destination is added to the Job.
Default:
No default
Values:
[username:password@]address[:port]/streamname
Where:
Example:
-sg janedoe:letmein@realserver.yourcompany.com/live.rm
-sg johndoe:letmein@172.16.0.34:4040/quarterlymeeting.rm
Process ID File -pid
A file where the process ID of the encoding session is written. Filename can be a relative or absolute path. If relative paths provided, the location is relative to the working directory. File is created at startup and deleted upon normal shutdown. If file exists and is and is writeable, the file is overwritten. See CROSS-PLATFORM FILE PATH section below for valid cross platform file paths.
Default:
No default
Values:
Any valid filename.
Example:
-pid "/usr/log/myfile.pid"
-pid "C:\jobs\job34.pid"
Options in this section define encoding settings for compressing audio and video into RealVideo and RealAudio format.
-ad Audience Definition -am Audio Mode -vm Video Mode -dt Disable 2-Pass -da Disable Audio -dv Disable Video -rs Resize -rq Resize Quality -arq Audio Resampling Quality
Each of these options are described in detail below.
Audience Definition or Audience File -ad
This is a comma separated list of Audience Files or Audience Definitions defined within the RealSystem Producer. The name of the audience may be abbreviated with the first few letters if referencing Audience Definitions in which case the closest matching audience definition is used where exact matches are preferred over partial matches. For example, "28k Dial-up" may be abbreviated with "28k" or just "28". If a Audience File is referenced, the full filename must be included, including file extension. If more than one audience with the same name matches, then an error is logged and encoding stops. This option may be called multiple times - each time it is called, the audiences are added to the Job.
Default:
16k,28k,56k,256k
Values:
A comma separated list of strings that matches the names of an Audience File or Audience Definitions defined within the RealSystem Producer.
Example:
-ad "28k,56k"
-ad 150k
-ad "28k Dial-up,56k Dial-up,256k DSL/Cable
Modem"
-ad "C:\settings\My 28k Modem.rpad"
-ad
"/files/28k.rpad,/files/56k.rpad"
-ad "28k.rpad,56k.rpad"
(searches local working directory).
Audio Mode -am
Describes the type of audio content. Certain codecs are tuned to encode voice frequency responses and others are turned to encode music. Audiences are defined with different choices of audio codec based on the type of input. This setting determines which audio codec to be assigned from an audience.
Default:
music
Values:
voice or music
Example:
-am voice
-am music
Video Mode -vm
Setting to control the picture quality of the encoded video. sharp=Sharpest Image, normal=Normal Motion, smooth=Smoothest Motion, slideshow=Slide Show.
Default:
normal
Values:
sharp, normal, smooth, slideshow
Example:
-vm sharp
-vm slideshow
Disable 2-Pass Encoding -dt
If option is present, the input file is read in single pass only. 2-pass is an encoding technique where the file is read in two passes. The first pass analyzes the file to determine where the most bits are required in the file. The second pass encodes the file using hints provided by the first pass. By disabling this option, the resulting file will be of lower quality but the encoding time is reduced by about one half. This option is applied to all outputs. 2-pass encoding only applies for encoding file to file so this option is ignored if input is a device (-ac, -vc) or output is a server (-sg).
Default:
This option takes no arguments. By default, 2-pass encoding is enabled in the command line unless this option is present.
Values:
No value required for this option.
Example:
-tp
Disable Audio -da
Option to disable audio streams from the output RealMedia file. Affects all output files.
Default:
NA
Values:
No value required for this option.
Example:
-da
Disable Video -dv
Option to disable video streams from the output RealMedia file. Affects all output files.
Default:
NA
Values:
No value required for this option.
Example:
-dv
Resize Video (output size) -rs
Sets the output video size in pixels. Ignored for audio only inputs. Default is not to resize which occurs if this option is not present. This filter is applied to all inputs. Width and height may be set as follows:
If width = 0 (e.g. 0x240) then width is computed from the height and input aspect ratio.
If height = 0 (e.g. 320x0) then height is computed from the width and input aspect ratio.
If height = 0 and width = 0 then no resizing occurs.
Width and height values must be divisible by 4 pixels. If width or height are not an even increment of 4 pixels, the value is rounded down to the nearest integer that is divisible by 4.
Default:
0x0
Values:
WxH
Where:
Example:
-rs 320x240
-rs 320x0 (resize width to 320 and maintain aspect ratio)
-rs
0x240 (resize to 240 high but maintain aspect ratio)
-rs 0x240 (resize to 240
high but maintain aspect ratio)
Resize Quality -rq
Affects the resulting quality of an output video when resize is applied. Choosing high results in a better quality resize but uses considerably more CPU. This filter is applied to all inputs. Ignored if -rs option omitted.
Default:
high
Values:
fast or high
Example:
-rq fast
-rq high
Audio Resampling Quality -arq
Affects the resulting quality of audio resampling operations. Resampling must be done if the sample rate required by the target audio codec is different from the input file or device sample rate. The producer automatically invokes the resampler for each audio codec as needed. Choosing 'high' results in an audio-only encode using as much as 2 times as much CPU for live or taking twice as long to encode for file to file encodes. The fast audio resampling algorithm does not incur additional CPU but results the encoded output having a slightly lower quality. In all cases, there is no pitch shift incurred by the audio resampler.
Default:
high
Values:
fast or high
Example:
-arq fast
-arq high
Options in this section define settings that are applied to the input before it is encoded to improve the quality of the output.

-h
Display Detailed Help (this file) -m
This option displays full detailed help for the RealSystem Producer in a system-dependent manor.
Default:
NA
Values:
No value required for this option.
Example:
-m
Print Device Information -pd
This is an informational option that extracts audio and video device information from the system for use in the -d option. See the -d option for information on how to use the information printed with this command. This option may only be used by itself on the command line. See USAGE section above.
Default:
NA
Values:
No value required for this option.
Example:
-pd
Print Audience Definitions -pa
This is an informational option that extracts Audience Definition information from the the application for use in the -ad option. See the -ad option for information on how to use the information printed with this command. This option may only be used by itself on the command line. See USAGE section above.
Default:
NA
Values:
No value required for this option.
Example:
-pa
Print Version Information -v
This option prints version information for the RealSystem Producer.
Default:
NA
Values:
No value required for this option.
Example:
-v
To specify an audience on the command line the -ad option is specified. An audience is a XML based file that specifies video codec, audio codec, bit rate and other settings. To customize audience settings the audience can be edited. Default audiences are located in a directory called 'audiences' located in the application root directory. These files are text formatted with XML. The files can be edited using any regular text editor or any GUI-based XML editor. See the RealSystem Producer Preview Guide for information on customizing audiences.
The temporary directory is defined by the tempDir setting in the user preferences file. If tempDir is set to %TEMP% in the preferences file, the Producer will search first for an environment variable called TEMP on Windows or TEMPDIR on Linux. If TEMPDIR does not exist on Linux, then the Producer will also attempt to use /tmp to write temporary files.
Note: Due to performance penalties of moving files between file systems, it is advisable to locate the temporary directory on the same drive as the location where media files are being written.
Logging preferences are defined in the user preferences file called 'producer.pref' located in the application root directory. The -lc, -dls and -dlf options described above allow logging preferences to be overridden.
The application may be stopped by using the Control-C command ('Ctrl' and 'c' keys pressed at the same time). A Ctrl-c signal will stop all the current job and begin the merge process if SureStream files are being created or simply update headers generate an index if Single Rate encoding.
The current encoding session may be canceled by pressing Ctrl-\ on UNIX or Ctrl-Break on Windows. These keyboard commands will issue cancel the current job and delete all temp files. Canceling a job results in no output!
On UNIX the following signals are trapped by the command line application with the respective actions. The Signal Name or Signal Number can be used as an argument the kill command on UNIX to remotely sends a signal to a running producer instance (Use the -pid option to get the process ID). By default the SIGTERM signal is sent by kill.
| Action | Description | Signal Name | Keyboard Shortcut |
| Stop | Stop encoding and merge files. | SIGINT (2) | Control+C |
| Cancel | Stop encoding, do not merge files and delete any temporary files. | SIGQUIT (3) | Control+\ |
On Windows the following events are trapped by the command line application with the respective actions. The pkill command included with the NT Resource Kit can be used to remotely send a signal to a running producer instance (Use the -pid option to get the process ID).
| Action | Description | Event Name | Keyboard Shortcut |
| Stop | Stop encoding and merge files. | CTRL_C_EVENT | Control+C |
| Cancel | Stop encoding, do not merge files and delete any temporary files. | CTRL_BREAK_EVENT | Control+Break |
Signals can also be sent to the producer Process ID (PID) by the operating system specific means.
On Windows one can write a C program or use the pkill command that is provided with the NT Resource Kit. The HandlerRoutine (http://msdn.microsoft.com/library/en-us/dllproc/conchar_5zz9.asp) in Microsoft Windows allows events to be generated by a C program and sent to a running producer instance by process ID. This and other signal handling routines are documented on the MSDN website (http://msdn.microsoft.com/).
On UNIX the kill command can be used to send a signal to an application or a C program may be written. The kill function in UNIX allows events to be generated by a C program and sent to a running producer instance by process ID. The Introduction To Unix Signals Programming (http://users.actcom.co.il/~choo/lupg/tutorials/signals/signals-programming.html) covers this in more detail.
The producer returns a 0 if no errors occurred. Otherwise, the producer returns a value of 1. This is useful when running the producer from within a script.
On UNIX the return code can be accessed by assigning the function call to a variable and then testing that variable's value. For example:
For example:
res=`producer -i myfile.avi` if [ $res -ge 1 ]; then echo "Huston, we have a problem."
Will pass the results of the producer call to the variable 'res' and then print the corresponding string if 'res' has a value of 1 or more. Note the back quotes used around the producer command. These are special quotes that cause the contents to be executed in place.
On Windows the return code can be accessed by using the ERRORLEVEL option to the IF command. From the DOS command line help on the IF command:
IF [NOT] ERRORLEVEL number command
Where:
For example:
producer -i myfile.avi IF NOT ERRORLEVEL 1 echo "Huston, we have a problem."
Will print the corresponding string is an error occurred with the previous command line execution of the producer.
In order to enable platform independent command line scripts, paths names are translated to be compliant to the platform the script is being run on. The following defines the translations that are done.
The stream name is the name given to a live RealMedia stream. This is the name that will be used when linking to RealMedia live stream. The following defines valid characters for RealMedia stream names:
Duration format is [D:][h:][m:]s[.xyz]
Where:
Limits for testing
Following are several examples demonstrating different applications of the RealSystem Producer command line interface.
Simple Example
producer -i input.avi
Encodes single input file 'input.avi' located in the current working directory to output file 'output.avi' in the same directory. All defaults are used which include 28k Dial-up and 56k Dial-up audience definitions, Audio Mode 'music' and Video Mode 'smoothest'.
Single input file to single output file
producer -i myFile.avi -o myRealMediaFile.rm
Generate an output file called 'myRealMediaFile.rm' from input file. Use default audiences, audioMode and videoMode.
Batch - Input filename with wildcard
producer -i *.avi
Generate one output file per input and output all files to the same directory. If input directory has 2 files; myfile1.avi and myfile2.avi, 2 output files are generated in the same directory as the input files called myfile1.rm and myfile2.rm. Each file is processed sequentially, one after another.
Batch - Input filename with wildcard and output directory
producer -i C:\capture\*.avi -o C:\movies\
Generate one output file per input and output all files in output directory. If input directory has 3 files, myfile1.avi, myfile2.avi and myfile3.avi, 3 output files are written to the C:\movies directory called myfile1.rm, myfile2.rm and myfile3.rm. Each file is processed sequentially, one after another.
Batch - Input directory
producer -i C:\capture\
Generate one output file per input and output all files in same directory. If input directory has 2 files; myfile1.mov and myfile2.mov, 2 output files are generated in the same directory as the input files called myfile1.rm and myfile2.rm. Each file is processed sequentially, one after another.
Batch - Input directory and output directory
producer -i /capture/ -o /home/janedoe/movies/
Generate one output file per input. If input directory has 3 files, myfile1.avi, myfile2.avi and myfile3.avi, 3 output files are written to the /home/janedoe/movies directory called myfile1.rm, myfile2.rm and myfile3.rm. If input directory does not exist, create it. Each file is processed sequentially, one after another.
