How to increase video cache buffer ? (2 Viewers)

Hi

Is there a way to define video cache size?
(on slow internet connections sometimes the video freeze to load the next frame...)

thanks.

This is a directshow codec problem. Nothing in the plugin you can configure to change that.

are you sure? cause for example, at XBMC you can define the size of the video cache to preload before playing...

Most videos start to stutter shortly after playing

I have no idea how XBMC plays the files. It might always save them to disk before, or use something like VLC or MPC-HC as player. These two have their own source filter implementation, so they CAN change the buffer.
This plugin is not responsible for playback, it only provides access to the urls and then builds the directshow graph with system filters, to play that url. This mean the cache would be a value of the filters used as source filter.

which filter Online Videos is using? ffdshow?
maybe as you say, at the filter itself there will be an option to change the buffer

In most cases the graph will start with this filter:
File Source (URL) Filter

What codec is used for playback totally depends on the file to play.

And so the question remains, how do I know exactly which codec was chosen for a given file? is it written in a log somewhere?
I was trying to watch a clip on YouTube, it was completely unwatchable, very choppy. Then I loaded the browser and watched the exact same clip - ran smoothly. So this is definitely a codec issue, we just need to figure out which one...

In most cases the graph will start with this filter:
File Source (URL) Filter

What codec is used for playback totally depends on the file to play.

You can try it with graphstudio.
When you start mediaportal and graphstudio, there is an option to connect to a remote program

I found out that the File Source (URL) Filter that is used on all http sources as source filter for the graph supports another interface that can be used to ask how much of the file to be played is already downloaded in memory. I implemented a way to use this information to delay the start of playback in MediaPortal until a percentage (configurable, default 2% now) is downloaded. This will be in the next version (0.20).
