Sliders and FF/RW needed, not in saved ASF file... dl0 <dl0banter[ at ]gmail.com> 6/7/2007 6:33:43 PM After figuring out what was wrong with my WMVCopy, I now have downloaded files from an encoder. This is fantastic. What's missing however, are the slider and FF/RW control on the media player. I'm sure this has something to do with the ASF file (duh) and I'm thinking there are probably some settings/functions I need to execute on the ASF samples as they come in... Where is this stuff located? Is it in the ASF control or in the Writers? Thanks, D

It should be created by default but, if it's not, you can try to enable it explicitly: - at the end of CWMVCopy::CreateWriter(), right after the call to m_pWriter->SetOutputFilename(), enumerate the sinks with m_pWriterAdvanced->GetSinkCount()/GetSink() - for each sink (there should be only 1), if the sink supports IWMWriterFileSink3, call IWMWriterFileSink3::SetAutoIndexing(TRUE) If that doesn't work, index the file after writing it in CWMVCopy::Copy(): release everything, then create an indexer with WMCreateIndexer(). You should index at least the video streams as WMT_IT_PRESENTATION_TIME/3000millisecs/WMT_IT_NEAREST_CLEAN_POINT (or 1000ms, but you'd better also index audio and image streams). -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm

Where I am stuck at is where you assign the OnStatus callback explicitly in the hr = m_pIndexer->StartIndexing( pwszOutputFile, &CWMVCopy::OnStatus, NULL ); call. This isn't working because of a casting issue. I found where he appears to be templatizing each of the callbacks but I don't see any assignment there. Also, I haven't quite clued into where the assignment of these things is happening for the other interfaces that us OnStatus. Since he appears to be templatizing everything and then doing an AddRef for each using the same pointer, I'm not exactly sure how you "get it back". If I can find that pointer in the above function call (as far as I understand) it seems I can pass it to the StartIndexing method. The program claims indexing is on but it isn't in the files I'm downloading so I started my attempt; I'm stuck at the point I mentioned but I'm still looking. Thanks for your help... D

This isn't working because of a casting issue. Why would you expect it to work? The method expects a pointer to a class (IWMStatusCallback*) while you are trying to pass a pointer to a virtual method. The callback is *not* a function but an interface. > I found where > he appears to be templatizing each of the callbacks but I > don't see > any assignment there. There are no templates in the sample. > Also, I haven't quite clued into where the > assignment of these things is happening for the other > interfaces that > us OnStatus. IWMReaderCallbackAdvanced : IWMReaderCallback : IWMStatusCallback : IUnknown The sample is using IWMReaderCallbackAdvanced and not just IWMStatusCallback, but IWMReaderCallbackAdvanced inherits IWMStatusCallback. > Since he appears to be templatizing everything and then > doing an AddRef for each using the same pointer, I'm not > exactly sure > how you "get it back". Again, there are no templates and, if you are referring to the implementation of CWMVCopy::QueryInterface(), it is not AddRef()ing the same pointer but the same object instance (itself) and returning different pointers, depending on the branch that gets executed, which are just stored in the same result parameter. > If I can find that pointer in the above > function call (as far as I understand) it seems I can pass > it to the > StartIndexing method. As the sample shows when using IWMReaderCallbackAdvanced, you need to use 'this' to let the compiler cast it to a reference to IWMStatusCallback (see the call to m_pReader->Open()). Also, notice that you will get the same CWMVCopy::OnStatus() implementation the sample uses for the copy, which may or may not work for the indexing. > The program claims indexing is on but it isn't in the > files I'm > downloading so I started my attempt; I'm stuck at the > point I > mentioned but I'm still looking. It occurred to me now that the problem may also be the seekable and stridable flags in the streaming header, which should be false while you need true. In CWMVCopy::CopyAttribute(), after all the attributes have been copied, set those 2 attributes to true. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm

I was answering my own questions with "What about this?" as in the pointer. Lame, I know. I figured out the indexer because what it was looking for in reference to its OnStatus callback pointer was simply "this". I haven't used C+ + for about 10 years so I had attempted stuff like this->OnStatus and the Classname::OnStatus and was looking for what I was missing and finally arrived at "this" and it worked perfectly. I really appreciate your time and I have learned bunches of stuff about this API from you guys.
