Buffer/cache for streaming movies & tv shows

Post by 00diabolic »

Hello,

I am wondering if the xbox cache partitions are whats used when you stream? I have 3 xboxs and 2 of them have very limited space 40gb HD and the other has the original 10gb on them. They also both have games ripped onto the HD's and are full. I plan to update those xboxs to the newest versions of xbmc 3.2/(3.3 when final released). My main xbox has about 1gb free and seems to stream video fine but will the other 2 xbox suffer due to having little or no free hd space?

I hope someone can let me know.

Thanks again for the ongoing support of the original xbox. :D

A lot changes went in newer versions for better video cache handling from mainline (thanks to Buzz) and they even allow you to change them through the GUI interface (smaller or larger, depending on how much memory your skin leaves free). The cache is in RAM not on disk and that's where the problem lies, as the box a total of 64 MB of RAM, with at least half used by the UI, and more used by the player code - enable debugging to see how much free RAM you have during playback (http://www.xbmc4xbox.org.uk/forum/viewt ... p?f=6&t=65)

You run though into strange issues if you have no free space at all, at some plugins write their data on disk, or XBMC4Xbox writes temporary files, so you should ensure that all partitions really have at least a few MBs free.

Thanks Dan Der3.. I figured the ram was what was used. The xbox has 3 or 4 cache drives (each 700-800mb I believe) it uses because it lacks more ram if I remember correctly. Are those used for anything other than games and why not?? I did see the size of one of those fall when I was streaming so I figured that's what was being used. My concern was that I would not be able to stream a 2 hrs plus movie or anything above 480p if I had no free space available. I'll have to see how it goes. Both of the xbox have at least 100mb free but nothing more then that. My main xbox has about 1gb free and seems to stream fine.

Also is there any chance we will see original source code for the nvidia chip on the xbox? As I remember it is still a protected secret by nvidia, that has not changed right? My dream has always been that it would leak or get released and we would have full access to the GPU which would boost performance significantly in XBMC. The xbox is over 10yrs old how much IP could really be left in it for nvidia. Perhaps I'll write a letter to them to see if I can get them to release it. If we did have access to the GPU would the xbmc4xbox community be able to use it?
