lav2mpeg(1) MJPEG tools manual lav2mpeg(1) NAME lav2mpeg - easy conversion of lav files to mpeg SYNOPSIS lav2mpeg [ options ] lavfile1 [lavfile2 ... lavfileN] DESCRIPTION lav2mpeg is a shell script to ease the use of the mjpeg utilities, provid- ing a convenient way to convert from MJPEG files to popular MPEG file for- mats. It supports output in VCD, medium and high rate VCD, SVCD, high rate SVCD, and generic mpeg1 and mpeg2 The input files may be any combination of AVI (.avi), Quicktime (.qt) or editlist files so long as they are all lavtools- readable (e.g. MJPEG-en- coded AVI/Quicktime or DV type 2 AVI). OPTIONS -s/S Turn stereo off/on (default auto) -k/K Turn keeping of raw files off/on (default off) -f/F Turn use of fifos off/on (default off) -l/L Turn logging of entire process off/on (default off) -n/N Turn "noisy logging" off/on (default off) -y/Y Turn use of yuvdenoise off/on (default off) -m one of MODES (see below) (default vcd) -e encoding quality : 0, 1, or 2 (default 2) -o output file ( defaults to firstInputFileName.mpg ) -b video bitrate in kbps ( only used when -o is "mpeg1" or "mpeg2" ) -a audio bitrate in kpbs ( only used when -o is not "vcd*" ) -q quality for mpeg2enc ( only used when -o is "mpeg1" or "mpeg2" ) -d dimensions XxY ( only used when -o is "mpeg1" or "mpeg2" ) defaults to same as input MODES vcd -- standard VCD (352x240 or 352x288) vcd_medium -- 1550kbps video VCD (352x240 or 352x288) vcd_high -- 1800kbps video VCD (352x240 or 352x288) svcd -- standard SVCD (480x480 or 480x576) svcd_high -- 3000kbps(max) vbr @qual=5 (480x480 or 480x576) mpeg1 -- honor -a -b -q -d flags default resolution same as input mpeg2 -- honor -a -b -q -d flags default resolution same as input FILES ~/.lav2mpegrc user configuration file. It is bash sourceable, and can modify any of the environment variables mentioned in the ENVIRONMENT section, or set the LAV2MPEG_OPTIONS variable to add default options. ENVIRONMENT NICEVALthe nice value of each command, set using 'nice -n command' YUVSCALER modify which command is called for yuvscaler LAV2WAVmodify which command is called for lav2wav MPLEX modify which command is called for mplex YUVDENOISE modify which command is called for yuvdenoise MPEG2ENC modify which command is called for mpeg2enC AUDIOENC audioenc is similar to those above, however, if it is set to 'mp2enc' it will use mp2enc rather than toolame, and set flags ap- propriotely. NOISYLOGFILE set the file used for noisy logging (-N) defaults to outputfile.log QUIETLOG set the file used for quiet logging. defaults to lav2mpeg.log if set to "" it will log only to screen LOGDATEdefaults to 1, set to 0 to not have the date logged in log or output (see man date for more info) LOGDATESTR will pass this on to 'date' to describe what time format to use. Only used if LOGDATE is not 0 LOGCOMMANDS if set to non-zero, will log to the quite log the commands used. Commands are always logged to NOISYLOGFILE if used LOGONLYif set to non-zero, will only log the commands it would use but not actually run any commands LAV2MPEGRC the lav2mpegrc file. Only beneficial if set from environment vari- able. VCD_MEDIUM_BR video bitrate for mode=vcd_medium VCD_HIGH_BR video bitrate for mode=vcd_high SVCD_HIGH_BR video bitrate for mode=svcd_high SVCD_HIGH_QUAL quality used (-q 0-30 to mpeg2enc) for SVCD_HIGH SVCD_HIGH_BUFFSIZE buffsize (-V to mpeg2enc) used for svcd_high defaults to 100 EXTRA_LAV2YUV set extra command line arguments to lav2yuv, which will be added on the end EXTRA_YUVSCALER set extra command line arguments to yuvscaler, which will be added on the end EXTRA_MPEG2ENC set extra command line arguments to mpeg2enc, which will be added on the end EXTRA_LAV2WAV set extra command line arguments to lav2wav, which will be added on the end EXTRA_AUDIOENC set extra command line arguments to mp2enc or toolame (depending on AUDIOENC), which will be added on the end EXTRA_MPLEX set extra command line arguments to mplex, which will be added on the end EXTRA_YUVDENOISE set extra command line arguments to yuvdenoise, which will be added on the end DIAGNOSTICS To simply see the commands that lav2mpeg would have called, run 'LOGONLY=1 lav2mpeg ...' BUGS Possibly. Please let the author know. AUTHOR Scott Moser <smoser at brickies dot net> EXAMPLES create a VCD compliant mpeg regardless of input named file.mpg lav2mpeg file.avi create a SVCD high rate mpeg from input named out.mpg lav2mpeg -o out.mpg -m svcd_high file.avi use lav2yuv.new for instead of lav2yuv, and add the '-M MMX' flag to yuvscaler: LAV2YUV="lav2yuv.new" EXTRA_YUVSCALER="-M MMX" lav2mpeg file.avi Please read other examples included in documentation for .lav2mpegrc usage MJPEG Tools Team JANUARY 2002 lav2mpeg(1)
