JM Reference Software README ============================ The latest version of this software can be obtained from: http://iphome.hhi.de/suehring/tml For reporting bugs please use the JM bug tracking system located at: https://ipbt.hhi.fraunhofer.de Please send comments and additions to Karsten.Suehring (at) hhi.fraunhofer.de and alexis.tourapis@dolby.com ====================================================================================== NOTE: This file contains only a quick overview. More detailed information can be found the "JM Reference Software Manual" in the doc/ subdirectory of this package. ====================================================================================== 1. Compilation 2. Command line parameters 3. Input/Output file format 4. Configuration files 5. Platform specific notes 1. Compilation -------------- 1.1 Windows ----------- Workspaces for MS Visual C++ 2003/2005/2008/2010 are provided with the names jm_vc7.sln - MS Visual C++ 2003 jm_vc8.sln - MS Visual C++ 2005 jm_vc9.sln - MS Visual C++ 2008 jm_vc10.sln - MS Visual C++ 2010 These contain encoder and decoder projects. 1.2 Unix -------- Before compiling in a UNIX environment please run the "unixprep.sh" script which will remove the DOS LF characters from the files and create object directories. Makefiles for GNU make are provided at the top level and in the lencod and ldecod directories. 1.3 MacOS X ----------- A workspace for XCode can be found in the main directory. The project can also be build using the UNIX build process (make). 2. Command line parameters -------------------------- 2.1 Encoder ----------- lencod.exe [-h] [-d default-file] [-f file] [-p parameter=value] All Parameters are initially taken from DEFAULTCONFIGFILENAME, defined in configfile.h (typically: "encoder.cfg") -h Show help on parameters. -d default-file Use the specified file as default configuration instead of the file in DEFAULTCONFIGFILENAME. -f file If an -f parameter is present in the command line then this file is used to update the defaults of DEFAULTCONFIGFILENAME. There can be more than one -f parameters present. -p parameter=value If -p parameters are present then these overide the default and the additional config file's settings, and are themselfes overridden by future -p parameters. There must be whitespace between -f and -p commands and their respecitive parameters. -v Show short version info. -V Show long version info. 2.2 Decoder ----------- ldecod.exe [-h] [-d default-file] [-f file] [-p parameter=value] All Parameters are initially taken from DEFAULTCONFIGFILENAME, defined in configfile.h (typically: "encoder.cfg") -h Show help on parameters. -d default-file Use the specified file as default configuration instead of the file in DEFAULTCONFIGFILENAME. -f file If an -f parameter is present in the command line then this file is used to update the defaults of DEFAULTCONFIGFILENAME. There can be more than one -f parameters present. -p parameter=value If -p parameters are present then these overide the default and the additional config file's settings, and are themselfes overridden by future -p parameters. There must be whitespace between -f and -p commands and their respecitive parameters. -v Show short version info. -V Show long version info. 3. Input/Output file format --------------------------- The source video material is read from raw YUV 4:2:0 data files. For output the same format is used. 4. Configuration files ---------------------- Sample encoder and decode configuration files are provided in the bin/ directory. These contain explanatory comments for each parameter. The generic structure is explained here. 4.1 Encoder ----------- = # Comments Whitespace is space and \t are the predefined names for Parameters and are case sensitive. See configfile.h for the definition of those names and their mapping to configinput->values. are either integers [0..9]* or strings. Integers must fit into the wordlengths, signed values are generally assumed. Strings containing no whitespace characters can be used directly. Strings containing whitespace characters are to be inclosed in double quotes ("string with whitespace") The double quote character is forbidden (may want to implement something smarter here). Any Parameters whose ParameterName is undefined lead to the termination of the program with an error message. Known bug/Shortcoming: zero-length strings (i.e. to signal an non-existing file have to be coded as "". 4.2 Decoder ----------- Beginning with JM 17.0 the decoder uses the same config file style like the encoder. 5. Platform specific notes -------------------------- This section contains hints for compiling and running the JM software on different operating systems. 5.1 MacOS X ----------- MacOs X has a UNIX core so most of the UNIX compile process will work. You might need the following modifications: a) Before Leopard (MacOS 10.5): in Makefile change "CC = $(shell which gcc)" to "CC = gcc" (it seems "which" doesn't work) b) MacOS "Tiger" (MacOS 10.4) doesn't come with ftime. We suggest using a third party ftime implementation, e.g. from: http://darwinsource.opendarwin.org/10.3.4/OpenSSL096-3/openssl/crypto/ftime.c 5.2 FreeBSD ----------- You might need to add "-lcompat" to LIBS in the Makefiles for correct linking.
