Resources: codecs - xgr files - misc. - newsgroup Media formats and filters What mediaformats dsj can de- and encode depends entirely on DirectShow filters that are installed on the runtime system. In general, dsj is capeable of playing all files that WindowsMedia Player or alternative players as MediaPlayer Classic or Zoomplayer are able to open. Note though, that dsj does neither bring any codec filters of its own, nor does it explicitely license you to use any 3rd party filters. We also do not deliver support for issues relating to 3rd party DirectShow filters (unless these issues are a dsj issue, of course). In general, it is recommendable to only install filters you really need. In particular: do not blindly install codec packs. Incompatibilities between DirectShow filters can lead to serious system instability. Installing ffdshow will usually cover most formats to encounter. Find in the following a listing of formats and links to the required codecs (this is an incomplete list of course...) : .asf, .wmv, .wma, .mpg1 & 3, standard .avi codecs (cinepak, Indeo etc.), DV: no prerequisits, filters are installed on any Windows running DirectX9 and WindowsMediaPlayer 9 or greater.

| XGR and GRF files These will let dsj do things, the ready made classes do not support out of the box. Before running these, open the files in your text editor. They may include filters not present on your system. Also you may not want to transcode an mpeg2 file for example, but some other format. In that case either directly modify the xml or open the xgr in GraphEdit, rebuild the graph and save it again. Note: Some of the functionality in these files is in the meantime (dsj 0_83x) covered by the classes in de.humatic.dsj.sink. We will keep the files downloadable though, as they may serve as examples for the use of xgr in dsj. |

GraphEdit (as well as the DirectShow SDK) is part of the Windows Platform SDK. The DirectX9 version does not offer export to XML anymore. A DirectX 8 version, that still does can be downloaded from here.
