Problem playing mkv files
 
Hi,

I use bs player for a long time, mostly with 720p mkv files.
Sometimes the video runs slower than audio, sometimes the video freezes and after 3-4 secs it plays normally.
Yesterday I tried to play a 1080p mkv file, but the fps was 10-12.
When I tried to play again 720p files, the video plays very slowly about 20-21 fps.
Which renderer is best for my case? Any other settings I have to adjust?
I use an Acer Aspire 8930 Notebook, with Nvidia 9600M GT, 4GB Ram, Windows Vista Home Edition.
Do I have to install any external codecs pack, like CCCP?

Pls advice
Chris

PS The strange thing is that some months ago, I played mkv 1080p files without any problem .....

When playng such a file, open preerences -> filters and see if there is a CoreAVC decoder. If so, click on it and disable deinterlace, skip debloking.
You didn't mentioned CPU, which is the most important in this moment.

There is no CoreAVC decoder, I haven't installed it.
As for CPU, its Intel Core Duo P7350 2.00 GHz.
I also have noticed that if fast moving scenes there sometimes there is a small freezing of the image.

If not, then what is it ? FFDshow video decoder ?

cvrak 11th May 2010 08:51 AM

There is a FFDshow decoder.
BS Player downloaded it during the installation. Do I have to make some special adjustments?

I don't have ffdshow installed to guide you, but you must find an option about "disable postprocessing"

cvrak 11th May 2010 02:45 PM

Do you think that CoreAVC is better decoder from FFDshow?
I'll download a trial version, but How can I activate it?

adicoto 11th May 2010 05:09 PM

CoreAVC it's lighter on CPU resources than ffdshow. Maybe you can find eslwhere another version to install.

Its true, CoreAVC is faster for decoding H264 than ffdshow, but it is not free.

And how this post can be helpful ? Any other advice ? Another free decoder that can be used ?

When BS.Player uses FFDshow you can simply set FFDshow's 'Postprocessing Level' under:
(rightclick >) Options > Properties > Video > FFDshow properties.
There you can slide 'postprocessing level' (option at the top of the window).

Another option is (with an appropriate videofile loaded):
(rightclick >) Options > Filters > Advanced
Then click on the [+]-sign in front of 'ffdshow Video Decoder' and subsequently click on 'ffdshow'.
In the 'column' in the middle of the window (actually it is the column at the left of ffdshow's video decoder configuration screen) there is (i.a.) the option
[ ] Postprocessing

:wink:

ffdshow has (beta) support for multiple processor cores, which should help improve performance.

  • New multi-threaded H.264 decoder: ffmpeg-mt
  • Improved rendering quality, memory usage and performance...
Read more here:
ffdshow tryouts | Changelog

To use ffmpeg-mt instead of libavcodec, go to Options> Filters> ffdshow video decoder and change decoder:

I installed CoreAVC but the problem remains.
I cannot find any setting in BS player to set the Core AVC active. How can I do this??

BSPeter 14th May 2010 04:38 PM

(rightclick >) Options > Preferences > Filter management ?
and - of course - in ffdshow disable it for H264.
:wink:

Thanks for the help. 720p filew are playing ok.
But 1080p video reaches 20-21 fps, maximum. Is there any way to improve it?
Is it possible something else blocking the player?
I use the EVR renderer in BS player. Do I have to use a specific renderer?

Sorry if i repeat myself, but I'm very confused. A few months ago, 1080p files played without problem, although CoreAVC wasn't installed

I am using a very old PC its PIII 733 Mhz Intel processor. The VGA card is also built-in. I am unable to play MKV files I also tried by installing CCCP & Matroska pack but of no use. Pls help, and pls don't ask me to upgrade the PC as I cann't afford. Thanks.
