Video Playback MPCStar General Discussions
1

I have been recording some movies with my Hauppauge PVR in .ts format. When I try to play the movie it starts and after a few seconds it freezes. It also won’t let me jump ahead.

This is the info from Mediainfo.

Any help would be appreciated.

Does it play seamlessly in another video player (e.g. VLC)?

Is your system powerful enough to play 1080p video?

3

These are the usual symptoms of a system that just doesn’t have enough speed/memory/resources to decode and play the video.

You could try converting the video stream to, say, XVid and see if that works adequately. If so, then your system probably isn’t powerful enough.

You can also see if the device can use a different encoding in the first place so that you don’t have to convert everything in the future.

I’m running Windows XP

Intel Quad Core 6600

4gb Memory

ATI Radeon HD 4670

It plays fine using Media Player Classic.

5

That certainly ought to be enough. Are you getting any logged errors or messages during playback?

Look also at the file info, particularly at the filter chain for anything showing an error or strange message.

Also you might try running some system resource monitoring tools while playing the video to see if you’re being constrained somewhere.

You may also want to try a different filter than the one you’ve got installed, just to see if it’s more compatible.

I don’t have MPCStar installed right now (had to scrape all filters and players due to some conflicting filters issues) but AFAIK MPCStar comes with its own internally bundled pack of decoding filters (mainly ffdshow and some few others on the side) so that will be a bit cumbersome.

But kluelos’ suggestion IS what you should consider if you want to troubleshoot MPCStar as far as this goes. You’ll have to disable H.264 decoding in the ffdshow copy which MPCStar uses and then install a third-party H.264 decoder (CoreAVC is by far the best and warmly-recommended).

Then see if you get the same issue. If you do, then at least you’ll know for sure that it’s not a decoder issue, and we’ll be able to consider this, some sort of bug.

Thanks,

I did what you suggested and now the files will start to play at 4 seconds on each file the screen flashes green for a second or 2. The files play jerky, and if I try to scroll forward they freeze. If I let them play then they get to a point and lock up.

Thanks for the help, I really appreciate it.

There is a menu (under File–>Info if I recall right) which will display the filter chain in MPCStar. Post a screenshot of that.

Let’s see what filters MPCStar uses for playing this file.

9

There are a number of items under filter, I wasn’t sure which one you needed so I selected this. It this isn’t could you let me know under which one it is.

Thanks,

Well, I said to post a screenshot of that window with the collapsed view of the filters, just to see all the filters present in the filter graph. Details on any one of them wasn’t relevant at this point.

Sorry for the delay.

I hope the attachment works.

Looking at the filter chain, you can see that the Video Decoder it is trying to use is ffdshow. However, the media is in the transport stream form (which is what that .ts extension indicates), not the more usual Program stream form, and ffdshow doesn’t support ts.

However, ffmpeg does.

What I’d try in your place is to install CCCP and see if just doing that doesn’t solve everything.

If not, what’s needed is a way to tell MPCStar to use ffmpeg instead. Exactly how is beyond my knowledge, as I don’t use the program that much, and clicking on the video decoder for more info inevitably crashes it for me.

That’s a tad weird. It loads both *ffdshow *and CoreAVC. What’s under the *ffdshow *entry, when you expand it?

How about the *CoreAVC *one?

How did you go about disabling H.264 decoding in MPCStar’s copy of ffdshow?

I will try that.

I also have the option of recording the file in M2TS or MP4.

I just want to get the best video and most comptable format.

Thanks again for the help.

Actually, the quality of the video is determined by the codec used (i.e. H.264 for best quality/compression ratio, these days) not by the container file type. Therefore, I’d warmly recommend MP4. Files with .ts extension stand for MPEG files which use the transport stream format, which is being meant and used mostly in digital broadcasting AFAIK.

As long as you intend to use the files locally or on fixed media (e.g. hard disk, DVD, flash disk, or whatever) you don’t need to use .ts files, if you have other choices.

However, I’m still not sure if this a matter of the format of the container (.ts versus MP4 or anything else) or rather a filter/codec conflict. The fact that you have two concurrent video decoding filters in you filter chain surprises me a bit.

So try to find an answer to each of the questions I’ve posted above.
