hackbart Posted March 15, 2017 Share Posted March 15, 2017 I got a couple of mails about this problem today https://social.msdn.microsoft.com/Forums/en-US/41309cf3-2ca5-4b75-9d3f-3cc9ebba8ac0/windows-media-foundation-bug-in-cumulative-update-kb3216755-windows-10?forum=mediafoundationdevelopment There seems to be a bug with a few windows components which cause a crash while tuning a channel. In all cases so far the used decoder was the Microsoft DTV Filter. If you have the same problem, just install the LAV Filters (or any other third party filter) and use them instead. To avoid crashes at start, try to start the DVBViewer with parameter -c or in safe mode (see start menu -> DVBViewer), open the DirectX Decoder Options and deselect the Microsoft decoder wherever it is selected.

Cian Posted March 16, 2017 Share Posted March 16, 2017 (edited) I had Cyberlink PDVD12 decoder enabled for h.264 which also caused the crash. Swapped to LAV and that worked. Thanks for the heads up. C. Edited March 16, 2017 by Cian Quote Link to comment
hackbart Posted March 16, 2017 Author Share Posted March 16, 2017 Good to know that also other decoders have this issue. Quote Link to comment
digitl Posted March 17, 2017 Share Posted March 17, 2017 I have installed the LAV filters but am still unable to launch DVBViewer successfully. Does LAV need to be configured? Or should it work straight out of the box? Quote Link to comment
hackbart Posted March 17, 2017 Author Share Posted March 17, 2017 There is no need for a configuration. Please make sure that you selected the decoder under Video A and B options in order to avoid that an other decoder is used instead. Quote Link to comment
digitl Posted March 17, 2017 Share Posted March 17, 2017 Thanks. LAV was enabled everywhere but I have had to remove two recent Windows 10 updates to get DVBViewer working again. Quote Link to comment
blomman Posted March 17, 2017 Share Posted March 17, 2017 Thanks for the LAV fix Quote Link to comment
digitl Posted March 18, 2017 Share Posted March 18, 2017 ...and Windows 10 has reinstalled the updates so DVBViewer has stopped again. I have rechecked and can see LAV everywhere I have looked and cannot see any references to Microsoft. The only non-LAV product I can see is 'Video Renderer' which is set to 'EVR Custom Video Renderer'. Do the attached screenshots provide any clues? I am running DVBViewer on a Hauppauge WinTV 88x (DVB-S2+IR) card if that is relevant? Quote Link to comment
Tjod Posted March 18, 2017 Share Posted March 18, 2017 Start the DVBViewer via start menu > DVBViewer > DVBViewer (Debug Mode) and try to select a channel. Close the DVBViewer if it not crashes and post a support.zip Quote Link to comment
digitl Posted March 18, 2017 Share Posted March 18, 2017 Thanks. Attached, though it crashed out on loading so I did not have an opportunity to try to select a channel. support.zip Quote Link to comment
Tjod Posted March 18, 2017 Share Posted March 18, 2017 Options > DirectX >> Audio A/B and replace there the Microsoft DTV-DVD Audio Decoder with LAV Audio 2 Quote Link to comment
digitl Posted March 19, 2017 Share Posted March 19, 2017 Thank you! I had, for some reason, thought the replacements were for video only. DVBViewer is back to its excellent self now! Quote Link to comment
Tjod Posted March 20, 2017 Share Posted March 20, 2017 The Windows Update KB4015438 should fix the problem. https://support.microsoft.com/en-gb/help/4015438/windows-10-update-kb4015438 Quote Link to comment
