Hopefully there will be a blog post out in a month or so with a guide on how to get started with MAP-Tk. We are also working on direct support for video files, but that will take a little longer. Im the mean time I suggest you use FFMPEG to extract frames. The command will be something like this:</div><div class=""><br class=""></div><div class=""> ffmpeg -i myvideo.avi frame-%05d.png</div><div class=""><br class=""></div><div class="">Then you can get a list of those frames to pass into MAP-Tk, for example using the “ls” command like this:</div><div class=""><br class=""></div><div class=""> ls -1 frame-*.png > frame_list.txt</div><div class=""><br class=""></div><div class="">If you have high frame rate video you may want to down sample the frames if there is a lot of redundancy between frames. You can do this either at extraction time or by specifying a subset of frames in the text file. To extract frames with FFMPEG at 1 frame per second try:</div><div class=""><br class=""></div><div class=""> ffmpeg -i myvideo.avi -vf fps=1 frame-%05d.png</div><div class=""><br class=""></div><div class="">If you extract all the frames, but only want MAP-Tk to operate on a reduced set, you could do something like this to get a list of every 10th frame:</div><div class=""><br class=""></div><div class=""> ls -1 frame-*0.png > frame_list.txt</div><div class=""><br class=""></div><div class="">Once you have extracted frames and the image files are listed sequentially in a text file you can set "image_list_file = frame_list.txt” in your MAP-Tk configuration files.</div><div class=""><br class=""></div><div class="">I hope this helps.</div><div class="">—Matt</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><br class=""><div><blockquote type="cite" class=""><div class="">On Feb 23, 2016, at 10:43 PM, yangbiaoshy <<a href="mailto:yangbiaoshy@163.com" class="">yangbiaoshy@163.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="font-family: 宋体, serif;

The GUI is a new addition to MAP-Tk. In the current release, the GUI is only used to visualize the results produced by the command line tools. The next minor release of MAP-Tk (v0.8.0 - expected in February or March) will add some processing capability to the GUI, but not yet end-to-end processing of video. Ultimately we plan to support end-to-end processing in the GUI, but it will take some time. MAP-Tk is still a relatively new project and is still considered “pre-release” software.</div><div class=""><br class=""></div><div class="">You can process video with the command line tools, but there are a few caveats to be aware of. First, direct support of video files is under development, so for now you will need to decode your video file into a sequence of image files (e.g. PNG or JPG). You can do this with ffmpeg or various other tools. Second, if you are using the precompiled binary packages for MAP-Tk v0.7.1 you should be aware of a known issue of missing libraries in the package (<a href="https://github.com/Kitware/maptk/issues/125" class="">https://github.com/Kitware/maptk/issues/125</a>). We hope to have this resolved in a week or two and then we will release new binaries with MAP-Tk v0.7.2.</div><div class=""><br class=""></div><div class="">I’m planning to write a blog post in the future that provides a step-by-step tutorial for running MAP-Tk, so keep a look out for that.</div><div class=""><br class=""></div><div class="">—Matt</div><div class=""><br class=""></div><div class=""><br class=""></div><br class=""><div class=""><blockquote type="cite" class=""><div class="">On Jan 15, 2016, at 3:36 AM, yangbiaoshy <<a href="mailto:yangbiaoshy@163.com" class="">yangbiaoshy@163.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><stationery style="white-space: normal; word-spacing: 0px; text-transform: none; color: rgb(0, 0, 17); font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px;" class=""><div class=""><font size="3" face="宋体" class=""><div class=""><font size="3" class="">hi :</font></div><div class=""><font size="3" face="宋体" class=""> I download map-tk software , I want to process video data, but I can't import any video file to software ,the map-tk gui only support conf\ply\krtd\txt , my video file format like mp4\avi and so on, so how to import video file to map-tk software!</font></div><div class=""><font size="3" class=""></font> </div><div class=""><font size="3" class="">thanks</font></div><div class=""> </div></font></div><div class=""> </div><div align="left" class=""><font color="#c0c0c0" size="2" face="Verdana" class="">2016-01-15</font></div><font size="2" face="Verdana" class=""><hr id="SignNameHR" align="left" size="2" style="height: 2px; width: 122px;" class=""></font><div class=""><font color="#c0c0c0" size="2" face="Verdana" class=""><span id="_FlashSignName" class="">yangbiaoshy</span></font></div></stationery><span style="white-space: normal; word-spacing: 0px; text-transform: none; float: none; color: rgb(0, 0, 17); font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px; display: inline !important;" class="">_______________________________________________</span><br style="white-space: normal; word-spacing: 0px; text-transform: none; color: rgb(0, 0, 17); font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px;" class=""><span style="white-space: normal; word-spacing: 0px; text-transform: none; float: none; color: rgb(0, 0, 17); font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px; display: inline !important;" class="">Kwiver-announce mailing list</span><br style="white-space: normal; word-spacing: 0px; text-transform: none; color: rgb(0, 0, 17); font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px;" class=""><a href="mailto:Kwiver-announce@public.kitware.com" style="white-space: normal; word-spacing: 0px; text-transform: none; font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px;" class="">Kwiver-announce@public.kitware.com</a><br style="white-space: normal; word-spacing: 0px; text-transform: none; color: rgb(0, 0, 17); font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px;" class=""><a href="http://public.kitware.com/mailman/listinfo/kwiver-announce" style="white-space: normal; word-spacing: 0px; text-transform: none; font-style: normal; font-variant: normal; font-weight: normal; font-size: 16px; line-height: 20px; font-family: 宋体, serif; letter-spacing: normal; text-indent: 0px; -webkit-text-stroke-width: 0px;" class="">http://public.kitware.com/mailman/listinfo/kwiver-announce</a></div></blockquote></div></font></div></div></blockquote></div><br class=""></body></html>
