Video stuttering

Post by al_infierno »

Hi, I'm having problems with video stuttering when streaming from my PC to PS3. I've looked at the discussions in these threads and had no luck with their solutions:

For the most part, the video seems to run fine for about 5 minutes or so before it starts stuttering, then I get a stutter every 30 seconds or so. I'm using a wireless connection so I guess the obvious answer is to buy a new cable (not exactly easy to plug in the PS3 from my setup but it's doable).

I'm just wondering if there's anything options-wise I can change to fix this, since I never have any issues with wireless streaming from paid online services (i.e. Netflix, Hulu etc.), but I understand that an improvised home-streaming setup is very different than a paid service.

Thanks in advance.

Online services generally compresses the media much more which reduces the quality and limits the bandwidth. They also usually have "adaptive quality" which means that the quality will be adjusted as necessary while playing to make sure the quality is the highest the currently available bandwidth can carry.

UPnP AV/DLNA has some stuff on adaptive bandwidth in the later versions of the standards, but I haven't really studied the details and don't know to what degree it's supported by devices. I doubt the support is very widespread, if this would at all be helpful in this context. This isn't implemented in UMS in any case, and I don't know how it could be, given the fact that once a transcoding has been started, UMS has no means of "communication" with the transcoding process and can't tell it to adjust the encoding parameters.

So, such online services aren't directly comparable, but UMS does have some bandwidth (and quality) limiting settings. You can configure your maximum network bandwidth, and you can also tweak for example the h.264 encoding settings. This should allow you to tweak it to some extent at least.
