We hope we have to get something useful for the GDCM/VTK community.<br><br>Regarding ffmpeg/vtk, I think they use ffmpeg in VTK just for writing avi video on non-windows platform but not for display videos. Actually vtk has vtkwin32videosource but it only grabs frames from a capture video not from external file. So I hope I can change vtkWin32Videosource to grab from the external dicom file using the GDCM. <br> I think GDCM read the multiframe dicom all at once. So we need to figure out how to read the frame on demand (e.g an event)<br><br>Best regards,<br>Ahmed Saad<br><br><br><div style="font-family: times new roman,new york,times,serif; font-size:

They divide their code into the codec<br>and the file format. For the file format you simply have to use gdcm<br>code into the ffmpeg framework. And for the codec, it will depend on<br>your code, for mpeg2, reuse the ffmpeg one, for raw image, I am pretty<br>sure they have something already.<br> Once this part is done, VTK CVS has a ffmpeg bridge, so this part<br>should be transparent (hopefully).<br><br> Subscribe to ffmpeg mailing list and start from
there. There code<br>base is very readable (if you skip all the crazy optimization<br>details).<br><br>HTH<br>-Mathieu<br><br>On 8/18/07, ahmed saad <ahmedalysaad2004@yahoo.com> wrote:<br>><br>> Hello,<br>> I'm new to GDCM from VTK/ITK background.
