interesting... all the times and all the years I have never seen my VLC buffer. I must have fast drives and LAN tongue.gif

Not unless you determine this to be a problem.. It's a lot of extra work that might not solve your problem. I am a big fan of reinstalling OS to keep them fresh and keep performance up, but I am not sure that is the right solution to your problem. Probably more a last resort solution IMO.

Have you tried another player ? Do those buffer too ? Or just VLC ?

I've been using LAN Speed Test to test my network lately.

Give it a shot biggrin.gif

It's possible too that your LAN speed is ok- but you have some type of throttling taking place. (not likely but possible anyways)

If your LAN tests out ok you might want to disable your network throttling

Hello,

below are my LAN speed for my drives. ( I have reinstalled my HTPC but dint helped me much). I see that sometimes my drives are vainishing form system. after i reboot my system the drive comes up again. why is this happening ?

482.3965 Mbps =
60.2995625 megabyte per second

60MB per second is enough to stream even multiple HD streams. That seems ok.

Your hard drives are fine. Your Network speed seems fine. (that's the good news)

I would look at your player. Do you have surround set up ? Do you use an AVR ? How do you hook up ? WITH HDMI ?

Have you tried WMC or WMP with SHARK 007 codecs ? Or MPC-HC ??? Might want to try another player other than VLC and see what you find.

I have connected my HTPC to TV directly using an HDMI cable.

My initial guess is that the player setting are not set up properly, and Audio/Video may not be decoded in the manner it needs to be for his setup.
LAN and HDD speeds appear to be adequate.

But, I can't figure out why it would be working from one drive and not another.

RinKu, I'm curious if all the Seagate Drives are from the same batch (possibly all ordered at the same time), and it's just part of a bad batch.

when i play movies in my desktop and watch it on tv via HDMI ( in my bedroom), the original Blu ray movies are buffering ( original in the sense directly copied form Blu ray cds)

when i try to copy files form my main htpc to other desktop or any laptop in my house via 1 Gbps LAN, i am getting speeds of only around 40 MBPS

this is my issue

Wait, I was reading this wrong. Maybe the issue is with the LAN on the Desktop (?).
It's not uncommon for those ports to get fried easily.

By any chance to you have access to a spare LAN (Ethernet) card you can plug in?

Mfusick,

do you think 60MBPS would be good speed as at least i should get 90 MBPS right ?


Wiley,


yes i do have one more ethernet port ( infact i have 2 ethernet ports where i can do teaming). i will try to use the other port and will check it out

do you guys think teaming will help me out ? ( as it might give me 2 Gbps speed and will it improve the overall network speed which goes through this HTPC ?)
post #39 of 70
I am confused.

Is your problem buffering? Or that you want your hard drives to read as being faster?

Because as I and others have said the two are likely not at all connected.

I wasn't necessarily thinking about teaming the 2 LAN ports on the Mobo, but it's worth a shot., as well as using the alternate port by itself to see if you are having the same issues.

However, I'm thinking it could be the onboard LAN controller, which is why I suggested a separate standalone card.

Me too.

I'm trying to get the setup right in my mind.

The HTPC is the device that houses all the drives, and has the AsRock Mobo in the Coolermaster Cosmos Case. Everything is working fine on this end, Correct?

What are the specs of the Desktop that is exhibiting the issues with streaming?

Hi,

let me explain everyone my issue again. I have HTPC which has movies and i want all other computers in my house to connect to it and play movies

my main issue here is hard drives speed ( while i copy movies from HTPC to another pc, speeds are not more more then 40 to 50 MBPS. this means if we watch blu ray movies form 3 to 4 simultaneously ( assume its different movie from different hard drives), then the video play bakc might fail or buffer from either any of 1 pc)

this is why i was thinking of whether there is problem with my lan or my hard drives. i am expecting 80 to 90 MBPS constant speed of coping files since its 1 Gbps Lan


i have tried adding my network cable from another onboard network slot. but i am getting the same speeds. i dont have external LAN controller . i can get it from frys but if it doesn't work out or if i get same speeds its not worth of getting from frys and returning it ( what you guys say)

one more thing is when i do teaming, my entire htpc gets stuck and goes to hung state. when i do force shutdown ( shutting off directly by pressing power), by next reboot it just stops at bios level. when i go to bios level i see that sometimes my ssd drive is not detected, sometimes my hard drive priorities gets changed etc). i have to do force shutdown 3 to 4 times to make it set right. then login to windows and remove teaming

is there anything wrong i am doing while doing teaming ?
post #44 of 70
There are different forms of teaming. If you are truing to make a 2Gbps connection then you will need a managed switch that supports trunking.

+1 to Mfusick for the heads up on LAN Speed Test, I've been looking for something like this for a while...

What exactly is "buffering" ???

My experience is VLC is a pretty good player in most general regards- it works well on lots of files and has few issues. The one issue it might have is that it does not support HD audio- but it does read the HD audio core (normal dolby or DTS and not the MASTER AUDIO or TRUE HD part ) and output perfectly fine the core basic DTS or Dolby signals. I rip lots of BR with the HD audio track, and even if I choose that track with VLC as my play it plays fine without "buffering"

I am not understanding what "buffering" means. Does that mean the movie takes a long time to start playing ? Or that it stops playing and starts backs up? Can you explain what happens when it is "buffering" and what you would like to improve ????

Here is what I suggest:

TEST LAN SPEED (between the video source location and your playback location)
TEST YOUR PLAYER (try to move a problem movie to the playback computer and try playing it back locally from that machine not over LAN. If it works this will show the problem is in the network signal path and not the player or machine)
and also
TEST YOUR PLAYER (You might want to try to play a movie that is a problem with another player like MPC-HC [free download and very good] or even Windows Media player )

If it's not your HDD then it must be your player (or software) or the network. I would test the network first- if your network is good then we can start testing more players and software.
Vlc buffers in the background. You can actually set how much to buffer by with vlc.
post #47 of 70
The problem is not your network since you have shown you can write at 60MBps+ over it.

The only way the problem is with your network would be if you are attempting multiple writes/reads across multiple clients/servers and your dumb switch/router cannot manage it.

Is your problem a read/write problem or a buffering question? I originally read it as the former but more recently you have started talking about buffering so now I don't know.

Copy a file locally from one drive to another, not across the LAN to see which drive is the cause.

P.S. Time the transfers yourself as Microsoft progress bar is notoriously off a lot of times.

Hi All,


forget about buffering. lets discuss about fixing the Hard Drive read/ Write speeds and my Lan network

the only reason i am worried is lets say i have a Original Blu Ray movie in one of my Hard drive. If i want to view that movie simultaneously across 3 or 4 systems in my house it wont work ( therotically it should work as i have 1 Gbps Lan and i should be able to get around 80 to 90 MBPS Speeds across entire network)
so across all 4 systems i should be able to watch the movie. but now i cannot as i am getting less speeds across my Lan

Watching four streams would be more of an issue with head seeking on the hard drive than on your network.

Especially since the file is likely fragmented and not contiguous.

wont i end up getting at least 80 to 90 MBPS Speeds across my network from my hard drives ?

Help me understand why you even care about your speeds. As has been stated your issue of buffering is not likely due to your hard drive speeds. I can't remember the last time I even checked the speed(s) of my hard drives because frankly it doesn't matter --- they are plenty fast to feed 5+ HD streams easily and I use a lot of green (and some 7200RPM) drives.

What we are saying is that this isn't what's causing your issue yet you seem to be fixated on the numerical reading on your computer screen that tells you how "fast" your hard drives are going. What I am trying to say is that you are likely going to still have buffering no matter what these speeds are reported as as I think your buffering issue is being caused by something entirely different.

+1. Hard drive speeds only matter if you are transferring large files, for streaming, its the network you have to contend with. HD speeds have nothing to do with streaming over the network. I stream multiple HD sources over my network all the time, even outside the home network and never had issues.

In order to transfer files at 80 to 90 MB/s over your network, the hard drive in your client (bedroom-desktop) has to be able to write consistently at the same rate.

my only main concern about the network speed is in future i want to use NAS storage and conenct it to HTPC using LAN wires ( 1 Gbps). so this is why i am worried about the speeds across network

Blu Ray has a maximum bitrate of 54 Mbit/s or 6.75 MB/s
post #58 of 70
Can I ask if these bluray files are exactly that and not tampered files? I guess what I'm asking is if you are running non encoded bluray files or are you playing some downloaded file you know nothing about? If it's the latter then that could cause stuttering for a whole different reason.

I figured this out. Thanks. Very interesting. I have used it for years without any buffering (ever)

I guess my set up is good tongue.gif

Excellent point (and fact). The OP should be able to have 10+ full HD streams simultaneously even with his "lowly" or "slow" Green drives.

This is why I and others have been trying to steer you away from fixating on the speeds reported and look elsewhere as a reason for your buffering issue.
