VideoDuke Known Issues

Problems that may arise while downloading online movies

  • Some SWF files don’t load external Flash movies correctly, and, as the result, cannot be played properly. This may occur if a SWF file requests external FLV using FLVPlayblack function call. For some reason this call bypasses the required procedures, and thus VideoDuke cannot trace loading, and some external resources may be omitted.
  • At this moment, VideoDuke supports capture of files transferred only over “plain” RTMP. Capture of files transferred over RTMP Tunneled (RTMPT), RTMP Secure (RTMPS) and RTMP Encrypted (RTMPE) is not currently supported by VideoDuke.
  • Currently, Microsoft Silverlight streaming video cannot be captured by VideoDuke.
  • Currently VideoDuke does not feature downloading of live RTMP stream (e.g. stream from web cameras, etc.)
  • At the moment, VideoDuke PRO does not support download of MPEG Transport Stream videos.
  • WebKit engine (which is used by VideoDuke for correct work of some of its options, like rendering web pages), provided in Mac OS X package of version 10.4.X and less, does not support all HTML5 features. Due to this fact, web pages that contain HTML5 elements in their code, will be displayed incorrectly by VideoDuke, including video on those pages. Therefore, media files may not be available for downloading via VideoDuke. However, this problem cannot be an applicable reason for a refund, as it is not VideoDuke’s fault, but a question of HTML5 support provided by older Mac OS X versions.
  • Sometimes files duplication is possible in the list of files which are available for downloading with VideoDuke. It happens when files have additional parameters in their names (like the date or time). As these parameters change, the links change correspondingly and VideoDuke treats them like the links to different files, though practically the file is always the same.
  • Sometimes a video is provided by a website in segments, but not in a single stream. Such videos can be downloaded by VideoDuke, however the downloaded files cannot be subsequently played.
