Title: How do filters work?? (Problem with TV recording playback)
Post by: pwantzel on January 27, 2010, 07:48:56 pm

I have a problem in which TV recordings were playing back with only audio, no video.  Mentioned in another thread, but it was off the original topic, so I'm starting a new one.  

I connected the TV stick to the PC with a problem and discovered that live video wouldn't play here either.  But on further investigation I found it did work on some channels.  Seemed to be HD didn't work and SD did work.  I guessed it might be a filter problem.  So I did the export DirectShow to clipboard and found they were different.  But no matter how many times I read the stuff in the wiki talking about filters, I couldn't figure out how to change anything.  On the PC that works, I don't remember doing anything with filters beyond installing CCCP.  Might it be useful to remove and reinstall CCCP, getting the latest version?  

What I'd really like is a discussion of filters and how they work in MC that I can understand.  Can you point me anywhere?

PC that works is Vista Business X64 SP2, the one that doesn't is XP Pro SP3.

In case it's useful, here are the filters on the PC that works:

Title: Re: How do filters work?? (Problem with TV recording playback)
Post by: Yaobing on January 28, 2010, 12:10:55 am

'Sonic CM(R) DS VideoDecoder 4.0' probably is part of the problem.  It was automatically loaded into the graph and it does not perform as it is supposed to.

To select a filter to use, go to Tools > Options > File Types.  Select file type jtv.  Select "JRiver video engine (using DirectShow filters)" as your "Playback Method".  Then select a video decoder and an audio decoder from the "Other Filters" list.  You do not need to select a "Source Filter" because MC automatically chooses the correct source filter for jtv files (for other file types you may or may not need to select a source filter).

Now what filters to select?

For audio, FFDShow Audio decoder and AC3Filter are automatically selected on your two computers respectively.  Since you do get audio, you may choose to use these.

For video, select an MPEG-2 decoder, (obviously do not choose Sonic CM(R) DS VideoDecoder 4.0).  Since you have installed CCCP, you can choose either "FFDShow Video Decoder" or "MPC- MPEG-2 Video Decoder (Gabest)".  You can experiment with either to decide which one gives you better result.  You may have other decoders to choose from.  You can experiment with them as well.  If you choose FFDShow, you need to make sure you configure FFDShow so it is set to decode MPEG-2.

More info on DirectShow filters, please read the wiki article on DirectShow (http://wiki.jrmediacenter.com/index.php/DirectShow_Playback_Guide).  The guide is slightly outdated because it refers to configuration methods for MC12.  For example it does not tell you about "File Types" option where you actually select filters in MC14.  Other than that, it is an excellent article from which to learn about DirectShow.

I know, I know... It is part of my mini-plan to eventually fix that up.  Of course, by the time I do it, you guys will revolutionize the UI again and mess me all up.   ;)  ;D
