Just send the file out the stream, as is. The server is attempting to transcode the video. The other Quirk is in 5GHz, where if it is allowed to auto-tune channels, it'll put the Primary one up from the secondary (so for example, CH153 as primary, CH149/157/161 as secondaries, with 155 being the "AC channel" - again, some chipsets get into an odd state here, esp.Code: Select all 00:52:18:280 - LOG_SYSTEM: system_call_waiting_prio : strProg /usr/bin/ffmpegĠ0:52:18:280 - LOG_SYSTEM: system_call_waiting_prio : strParam -threads 2 -i "/share/DNLA/.-DL.DD5.1.H.264.mkv" -vcodec mpeg2video -sameq -acodec copy -f vob -copyts -y "/var/twonkymedia/twonkymedia/db/cache/3f139d00a7de7e0a8e7f6c4bdf5c173f/MPEG/.-DL.DD5.1.H." Quirks - Marvell, in 2.4GHz, if set to auto tries to do VHT40/20 (11ac), and some chipsets can get into a bad state - I've seen this first hand with Broadcom/Realtek/Intel - to fix this - put the radio into B/G/N mode - nothing lost, as TurboQAM clients are far and few between. I'm thinking this is a Marvell/Broadcom interoperability issue that I've seen before.ġ) Go to the Wireless settings in the WRT, and check 2.4GHz, ensure that auto channel is not selected, mode is B/G/N-mixed, and 20MHz channels onlyĢ) 5GHz - Auto mode (A/N/AC), channel width to auto, and select either Ch48 or Ch149 Report back - I'm adding a couple of pics below based on some quick research over the Google to see if we're aligned on the HW being used.īased on your results - I don't think this is a Samba client/server issue - seems more specific to WiFi. I'm trying to get my head around this in more detail, but if I'm reading it correctly, your setup is like below:ġ) WRT1900ac - gigE to desktop/laptop is all good - around 75MB/Sec w/o Media PrioritizationĢ) WiFi performance for Write/Read over 2.4GHz and 5GHz is poor relative to wired - it'll rarely get close, but 10MB/Sec on the Laptop 2.4GHz is still a bit on the slow sideģ) nVidia Shield TV box - very poor performance over SMB - note that the nVidia box, if I read the specs right, it a 2*2:2 802.11ac, so WiFi should be good if coverage is good.Ĥ) uPNP seems to stream well (DLNA? via the Twonky Media Server in the WRT?)ġ) Attach the GoFlex direct to the Shield box - see what happens thereĢ) Rule out if WiFi is an issue by temporarily using the GiGE connection on the Shield and see what happens with SMB and DLNA/uPNP sounds like maybe we have more than one issue to solve. If you have any other ideas, I welcome them. You have been way more help for me than Linksys. Also I can't see the transfer speeds over UPNP so I have no idea if it's faster than SMB or not. but that's not the preferred setup since upnp can't be a library. Oddly, if I use UPNP instead of SMB, I can watch the videos just fine. The biggest issue I have at this point is that the shield tv read speeds from the attached drive are so horribly slow over SMB. With media prioritization, I only get 3MB/s read on cat5. If I leave it on USB 3.0 on the router and hook my laptop to the router with cat5 cable, I get 75MB/s write. If I hook it straight to my computer I get 75MB/s-85MB/s in either direction. HDD is Seagate Free Agent GoFlex 1TB with USB 3.0 Not sure the specs but P/N is 9Zf2A5-500. I tried the other port (2.0/esata) before but it was even slower than the 3.0 port. From an nvidia shield tv (android tv) on 5 ghz wifi, I still only can read from the drive at 2.7MB/s, which sucks since the whole point is for the attached storage to be the centralized media, and Kodi won't even play a video without freezing regularly over SMB. Max speeds now are 10MB/s read or write on my laptop over wifi (2.4ghz). That got me a few more MB/s (megabyte, not bit) over wifi. I have disabled media prioritization per your suggestion earlier. I had a 5TB Seagate BackupPlus external formatted NTFS - It's USB3, and since it's a SMR drive, write performance isn't optimal compared to a PMR drive, but even there - copying a large MP4 file (very large 4GB video file), I see around 65 to 70 MB/Sec, which is slightly slower than my intel based NAS box - media prioritization brings things down to about 5MB/Sec - this is over ethernet.įastest 11ac machine I have only has a 2 stream radio, but even there, it'll push 32-35 MB/Sec. Second - move over to the eSATA/USB2 port (seriously.) and see what happens there.ġ) What file system is used on the external disk? NTFS, FAT32, or exFATĢ) What is the vendor/model of the USB drive?ģ) Try a different USB 3.0 cable, some are non-spec, and run slow. the performance you're seeing isn't consistent with what many folks have observed.įirst - disable media prioritization - it's a switch, so previous settings won't be lost.
