Philips TV 65OLED854 - Android TV - 4K buffering - TheSwede86 - 2020-04-05 Hello, I am having problems with buffering on a 4K video playing on my TV - Philips 65OLED854 running Kodi through Android TV playing from my NAS (more info below). The build reported by Kodi is "Kodi 18.5 Git:20191116-37f51f6e63" running on Android 9.0.0 API level 28 (kernel: Linux 4.9.125). I thought my NAS-device where the media resides on could be the bottleneck (Intel Celeron J1800 dual-core @ 2.4 GHz w. 8GB of RAM) but I can see during playback that the NAS reports around 12% CPU and 17% RAM-utilization during playback. When looking at "Player process info" (when pressing "O" during playback) it reports "System memory usage" as around 75% which is steady even just before it starts to buffer. However when activating the debug option I see that all cores on my TV are shown with 0% utilization but "Kodi-CPU" is around 130% and then goes to 60-70% after the buffering issue has occured. The connection to my TV where Kodi is running is through ethernet (Cat6) and my NAS is also connected through ethernet (Cat6) through a gigabit-compatible router so its gigabit all the way. The NAS reports around 10-11MBps network utilization which is around 80Mbit and a far cry from what the network infrastructure can provide.

There is a newer Kodi version for Android for some time now. Please first upgrade.

Philips are not known for having very powerful and speedy hardware in their TV sets. 10-11 MBps sounds like a 100Mbit connection.

Thank you for your reply. Sorry for the old info: Build: Kodi 18.6 Git: 20200229-8e967df921 Compiled: 2020-02-29 I'll try tomorrow using iperf between my TV (using Termux) and my NAS and report back Update 2020-04-05: The movie I am trying to stream has (according to VLC, Tools > Media Information > Statistics) a content bitrate of around 90349kb/s and my iPerf results between the TV and my NAS are: Server = NAS Client = TV Figures taken from TV [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 112 MBytes 11496 KBytes/sec 0 sender [ 5] 0.00-10.04 sec 112 MBytes 11415 KBytes/sec receiver So unless I'm off here: 90349kbps ~ 11293KBps so the TV's NIC can barely fetch data fast enough through the network from the NAS and that explains the buffering? RE: Philips TV 65OLED854 - Android TV - 4K buffering - kalima - 2020-04-13 hello @TheSwede86 , i have the same issue with 65OLED804. Philips use 100mbit connection. We can't have usb to gigabit port adaptor I use htpc for the moment. I will switch to Nvidia Shield. I don't found fix for the issue.

Yeah I tried with WiFi instead and I got these figures; Server = NAS Client = TV Figures taken from TV [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 197 MBytes 20203 KBytes/sec sender [ 5] 0.00-10.04 sec 197 MBytes 20116 KBytes/sec receiver So around 40-50% better performance using WiFi then ethernet (my router is an 802.11ac 2x2 MIMO w. 1734Mbps on the 5GHz band). I also tried using a "USB to Gigabit Ethernet"-adapter (USB 3.0) and tried both the USB 2.0 and 3.0 port on the TV but nothing... The chipset inside the adapter I tried was "ASIX AX88179" which seems to have been supported since kernel 3.9 and the TV has kernel 4.9.125. I still get buffering issues though even using WiFi which is around 40-50% better then their sh*tty ethernet which is sad |
