[QUOTE="Owlsroost, post: 763459, member: 83973"] Just to summarise - Both Seb's v25 patch and my hacked TsReader will force a remove and re-add of video/audio filters on every channel change, so that (as mm has found) should fix the FFDShow DXVA SD<->HD corruption problem. But we don't really want to do this for all decode filters (I assume) so yes, we could make it selective in TsReader so it's only forced for FFDShow DXVA, but there are probably other decoders that need the fix too....any thoughts ? I'd still like to have proper checking of the graph state before filter removal (just calling _mediaCtrl.Stop() doesn't guarantee it's actually stopped when it returns - the call is not necessarily synchronous, according to MS). Attached is a patch including Seb's v1 mod and some graph state checking code - it builds OK but I haven't had a chance to run it yet.... Tony [/QUOTE]
