Baron_Harkonnen Posted December 2, 2011 Posted December 2, 2011 Hi, I have a problem - when i play movies from unraid (v.4.7) (with VLC, on MAC OS X Lion), the video stutters. it rarely happens with short movies (like tv series), but with long movies, especially HD video, it happens quiet often (sometimes every 10 minutes no huge 16+ GB movies) I'm pretty sure it has something to do with buffering (because when i raised VLC file buffering to 3000 ms - it helped a bit). i don't think the problem is with VLC or OS, because when i play the same movie from local HDD everything runs smoothly. my LAN is Gigalan, and everything seems to be configured right (i mean the router and stuff...) my shares are configured to Fill-up, and split level set to 0, so it not like video is stored on different drives... on a side note, i remember when i just got the unraid up and running i had no problems (but i had less HDDs, and less movies...maybe it has something to do with that?).problems started after a month or so...unfortunatly i don't remember doing anything particular to unraid, or to OS X, that could trigger the problem. What do you think? maybe cache drive can help? if yes - which is best? how big it should be? can i use laptop drive (i just have one lying around...)? let me know if any additional info is needed Appreciate your help
mbryanr Posted December 2, 2011 Posted December 2, 2011 Post a syslog...maybe there is a clue there. You shouldn't have any problem from the unRAID side of streaming full BD (high bitrate) over your network. Cache drive won't help. Here is a thorough test completed recently... http://lime-technology.com/forum/index.php?topic=9746.msg93536#msg93536
Baron_Harkonnen Posted December 3, 2011 Author Posted December 3, 2011 here's part of log around the time i tried to watch a movie yesterday (i excluded "minor isuess" because all i've seen is "Tower shfs: duplicate object: /mnt/disk2/MEDIA/MOVIES/._.DS_Store (Minor Issues)" repeating over and over), but i also included a full log (with minor isuess and everything) in a file.

mbryanr Posted December 4, 2011 Posted December 4, 2011 Do you know why you lost the network connection? I would setup a static IP for your unRAID server. Also, anything else included in your network? Switch? Router #? And results from ethtool eth0 ethtool -i ifconfig eth0 ^^these can also be found from unMENU--->System Info-->Ethernet for comparison Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: pumbg Wake-on: g Current message level: 0x00000033 (51) Link detected: yes NIC driver info (from ethtool -i) driver: r8169 version: 2.3LK-NAPI firmware-version: bus-info: 0000:04:00.0 Ethernet config info (from ifconfig) eth0 Link encap:Ethernet HWaddr 48:5b:39:79:f8:84 inet addr:192.168.1.108 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:312852 errors:0 dropped:0 overruns:0 frame:0 TX packets:603844 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:25851072 (24.6 MiB) TX bytes:862584373 (822.6 MiB) Interrupt:30 Base address:0x8000
lishpy Posted December 4, 2011 Posted December 4, 2011 You may be having network issues, but I'd also recommend scrapping VLC and using MPlayerX. VLC is known to not have the smoothest playback in OS X and I've experienced it first hand especially with larger 1080p files. Just a recommendation once you get your network issues under control.

"view/edit" - /boot/config/network.cfg, right? regarding my network i do have a hub beffore router - D-Link DGS1008D, which is connected to router NETGEAR ProSafe VPN Firewall FVS336G. it's configured to give specific IP address to certain MAC address (so my router makes tower to be always 192,198,1,15). regarding the stutter - i started to use MplayerX - it's nice, and i had no stutter on 1,7 GB files (40min 720p serial) at all with that player so far. briefly checked some huge 1080p (watched like 20min or so - no stutter) ill watch some whole movie tomorrow (i hope) mean while, thanks for all your help, and please let me know if you still see some problem with my network, even with mplayer i'd still like to correct it vadim
Joe L. Posted December 10, 2011 Posted December 10, 2011 RX packets:914060101 errors:0 dropped:110124 overruns:0 frame:0 You are dropping packets. Step 1. Try a different cable
Baron_Harkonnen Posted December 14, 2011 Author Posted December 14, 2011 Hi, I did several things - i did change cables (external ones - not inside the walls yet...) also switched to MplayerX - stutter stopped right away in MplayerX wonderful player! the dropped packets did not stop however...(at least i think so - because it spiked from 110124 to something around 2,500,000 (maybe it spiked couse i changed cables without shutting down the server?) but i also disabled DFS on my server after the restart i had no dropped packets! not a single one in 2 days now! so i guess problem solved! Thanks for helping me! P.s. i would like to know though, just out of curiosity - was it the cable, or the DFS thing?
