in a distributed processing environments constructed on heterogeneous machines and architectures. +The idea is to split the codec work on different machine using a front end (tcpvmexportd) that load the request module (e.g. export_mpeg2enc.so): each new instances receive from export_pvm a subset of frame and create a portion of the final video file. When all the slave process on host 1,2..n are running (see the schema below) the main task on host 0 (transcode) is waiting for a free task: at the end, when all the video frame are decoded, an others slave processes (merger on host x,y,z) merge all produced file. +For instance only this export module are supported: + +Video: + null (built in) + mpeg2enc + mpeg + divx5 + ffmpeg + xvid + + +Audio: + null (built in) + mp2enc + mpeg + divx5 + ffmpeg + xvid + + +Support for multipass (standard and built in) + +--------------- +* Schema +--------------- + + + /---------\ /---------\ + | | | load | + |transcode |--> from filter output--> | export | + | host 0 | | pvm | + \---------/ \---------/ + | + | spawn process + \ / + | + ____________|________________ + | | | + | | | + load external module /-----------\ /----------\ /----------\ + /--------------\ | slave | | slave | | slave | + |export_xxx.so |<______ |tcpvmexportd| |tcpvmexportd| |tcpvmexportd| + \--------------/ | host 1 | | host 2 | | host n | + \-----------/ \----------/ \----------/ + \___________|_______________/ + | + \ / + | + /--------------\ + | share fs | + | nfs | +spawned by export_pvm | | + /-----------\ \--------------/ + | mergers | | + |tcpvmexportd|___________________________/ + |host x,y,z | + \-----------/ + | + | + \/ +/--------------\ +| output video | +| file | +\--------------/ + +--------------- +* Usage +--------------- + +export_pvm module gets its options from transcode command line with -F option + +Running +transcode -y pvm -F list + +the module give all the options + +[export_pvm.so] v0.0.1 (2003-07-19) (video) * | (audio) * +[export_pvm.so] -F configfile,[[nproc]:[maxproc]:[nfrxtask]] +[export_pvm.so] nproc,maxproc,nfrxtask override the parameter present in the config file +[export_pvm.so] List of known and supported codecs: +[export_pvm.so] Supported Modules +[export_pvm.so] -------------------- +[export_pvm.so] null mp2enc +[export_pvm.so] mpeg2enc divx5 +[export_pvm.so] mpeg ffmpeg +[export_pvm.so] xvid +[export_pvm.so] -------------------- + +where + +configfile configuration file (see below) +nproc number of process for a single host +maxproc max process in the cluster +nfrxtask number of frame that a single slave task elab.

normal export module) +2) If you have machine with a single CPU set NumProcMaxForHost to 1 max 2 and set MaxProcForCluster to number of host * NumProcMaxForHost + 1 +3) Set 1-2 process for each CPU +4) If the decode process never wait for a free task then you probably found the right configuration (add more slave host is useless: you need to speed up the decode process). +5) If you plan to have a system file don't multiplex the merged audio and video, but run the built in system merge process (this remove an A/V sync problem). +6) If you plan to create a DVD with dvdauthor then set BuildOnlyBatchMergeList=2 in the [SystemMerger] section and pass to dvdauthor the system files generated (force BuildOnlyIntermediateFile=1 in the [SystemList] section). (with dvdauthor alpha 338 use this command dvdauthor -o mydir -c 0:00,x:yz mympeg.mpeg-000000 -c c 0:00,x:yz mympeg.mpeg-000001 ........ where x:yz is the value set in NumElabFrameForTask (e.g. NumElabFrameForTask=99 and PAL x:yz=3:24)) +7) If you enable the multipass option (-R 1,2) the video and audio log will be created in the output directory (option -o and -m). +8) If you plan to create an avi with multipass, you can use the internal multipass (it takes less time then standard multipass option (set InternalMultipass=1)) +9) If you specify InternalMultipass=1 in cfg file and -R (1,2,3) in cmd line, -R option will be used. + + +--------------- +* Change log +--------------- + +2003-09-22 * acinclude.m4 aclocal.m4 docs/export_pvm.txt docs/man/tcpvmexportd.1 export/export_ffmpeg.c export/export_pvm.c export/Makefile.am pvm3/export_pvm_slave.c pvm3/export_pvm_slave.h pvm3/external_codec.c pvm3/external_codec.h pvm3/Makefile.am pvm3/pvm_functions.c pvm3/pvm_functions.h pvm3/pvm_parser.c pvm3/pvm_parser.h pvm3/pvm_version.h pvm3/tcpvmexportd.c pvm3/vob_pack_unpack.c pvm3/vob_pack_unpack.h src/Makefile.am src/tc_func_excl.h src/tc_functions.c src/tc_functions.h src/transcode.c src/transcode.h + +- added support for ffmpeg,divx4,divx5,af6,xvid,xvid2 encode module. +- added multipass and internal multipass support. +- enable pvm3 by default. +- bugfix. + +2003-08-21 * docs/export_pvm.txt export/export_pvm.c pvm3/external_codec.c pvm3/tcpvmexportd.c + +- added support for mpeg encode. + +2003-08-20 * docs/export_pvm.txt docs/man/tcpvmexportd.1 docs/pvm.cfg export/export_pvm.c pvm3/export_pvm_slave.c pvm3/export_pvm_slave.h pvm3/pvm_parser.c pvm3/pvm_parser.h pvm3/pvm_version.h pvm3/tcpvmexportd.c + +- added BuildOnlyBatchMergeList=2 in [SystemMerger] section to build only the intermediate system files and BuildOnlyIntermediateFile in [SystemList] section (dvdauthor don't like a merged file). + +2003-08-12 * first release of export_pvm + + + + +--------------- +* To do +--------------- + +- add a really support for A/V multithread option (-u) (for instance is set to 1). +- create a resource manager +- retrieve encoded frame without nfs +- balancing weight based +- extension to other codec +- remove the nfs dependency +- more.... + + + +--------------- +* Bugs +--------------- + +- please send me an e-mail diff --git a/debian/transcode/transcode-1.1.7/docs/pvm3/pvm_10x.cfg b/debian/transcode/transcode-1.1.7/docs/pvm3/pvm_10x.cfg new file mode 100644 index 00000000..7da7ca49 --- /dev/null +++ b/debian/transcode/transcode-1.1.7/docs/pvm3/pvm_10x.cfg @@ -0,0 +1,79 @@ +[PvmHostCapability] +NumProcMaxForHost = 1 +MaxProcForCluster = 10 +NumElabFrameForTask = 100 +(Host) +Hostname = marzio +NumProcMax = 2 +(Host) +Hostname = elisa +NumProcMax = 2 +(Host) +Hostname = cinzia +NumProcMax = 1 +(Host) +Hostname = lorenzo +NumProcMax = 1 + +[VideoMerger] +Hostname=marzio +BuildOnlyBatchMergeList=0 #if [SystemMerger] exist then BuildOnlyBatchMergeList=1 + +[AudioMerger] +Hostname=marzio +BuildOnlyBatchMergeList=0 #if [SystemMerger] exist then BuildOnlyBatchMergeList=1 + +[SystemMerger] +Hostname=marzio +BuildOnlyBatchMergeList=0 +MultiplexParams="-f 8" #multiplex parameters + +[ExportVideoModule] +Codec=mpeg2enc +Param1=8 +Param2= +Param3= + +[ExportAudioModule] +Codec=mp2enc +Param1= +Param2= +Param3= + +# The section next 5 sections are for internal use of tcpvmexportd +#[SystemList] +#Destination = /my/dest/file.mpeg +#Codec = mpeg2enc-mp2enc +#MultiplexParams="-f 8" +#BuildOnlyBatchMergeList=0 #
