I have heard it is a "container format" ? What's that ? + + A container format allows you to combine different multimedia streams + (most of the time Audio and video) into one single file. Multimedia + containers are for example the well known AVI (.avi), MPEG (.mpg, .mpeg), + OGM (.ogm), MP4 (.mp4) or Realmedia (.rm, .rmvb) + + The matroska project is a free, opensource container format, aiming to be + able to offer a lot of advanced features, which older formats like AVI + can't handle, on an extensible basis. Matroska supports for example the + storage of Variable Bitrate audio content (VBR) without any hassles, + Variable Framerates (VFR), Chapters, attachment of files, Error Detection + (EDC) and modern A/V Codecs like "Advanced Audio Coding" (AAC), "Ogg + Vorbis" or "Realvideo 9" (RV9), all things AVI can't handle. + + (This text is copied from the "Matroska FAQ" <http://forum.doom9.org> + Forum: New AV/Formats - Containers) + + +Which deinterlacing-Filter should i use ? + + I don't know, but there are really interesting informations/pictures at + <http://home.knuut.de/MWieser_/vf_raw_ntv_3/>. + + +I don't like your encoding-options.

What's wrong ? + + You can only add the movie to the queuefile, if the cursor isn't on the + FileName dialog. + + +What does the fields in the file queue.vdrrip mean ? + + e.g.: /video/%Irgendwie_und_Sowieso/2003-09-11.21:43.50.50.rec/001.vdr; + Irgendwie_und_Sowieso;350;1;lavc;896;2;15;712;568;0;4;496;360; + lame;96;0;lb;1;avi;1 + + /video/.../001.vdr: path of the first vdr-file + Irgendwie_und_Sowieso: name of the encoded movie + 350: filesize of one file + 1: number of resulting Files + lavc: video codec + 896: video bitrate + 2: min quantizer + 15: max quantizer + 712: crop width + 568: crop height + 0: crop pos x + 4: crop pos y + 496: scale width + 360: scale height + lame: audio codec + 96: audio bitrate + 0: audio id + lb: postprocess-setting(s) + 1: rename vdr-dir after encoding (0: don't rename) + avi: container-format + 1: encode only preview (0: encode all) + + +Is it possible to do the real encoding process on an other machine within +a network ? + + Yes, it is ! + + First you have to mount two directories (e.g. nfs) on the other machine: + + - /video* to the same mountpoint to access the vdr-files. Read-only is + enough, if you didn't set the parameter "rename after encoding" to + "yes" in the setup-menu. + - /<vdr-config-dir>/plugins to a arbitary mountpoint (read-write), + because there are the nessecary files queue.vdrrip, lock.vdrrip and + encode.vdrrip. + + Then you only have to install mplayer/mencoder with all needed codecs and + container-tools, and copy the queuehandler (/scripts/queuehandler.sh & + /scripts/queuehandler.sh.conf) and perhaps vdrsync.pl to e.g. + /usr/local/bin. See the table in the file INSTALL for further + informations. + + +Why do I get the error "Can't open main ifo from dvd !" or "Can't open +ifo x !" if I try to encode a DVD ? + + Probably the DVD is encrypted. Copying encrypted DVD's is illegal in many + countries. Don't send any questions regarding encrypted DVD's. |
