RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - Milhouse - 2015-03-25 New OpenELEC Isengard build #0324: RPi / RPi2 (Supercedes previous build) Code: # uname -a Based on tip of OpenELEC master (115800e4, changelog) and tip of XBMC master (1fb19a3a, changelog) with the following modifications:
RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - hdmkv - 2015-03-25 Thank you. So, I finally started testing with my Pi2 with build #0324, and... - 23.976 is perfect, as is 59.940, 24, 60 - Haven't tested mpeg2 yet (OTA HD) - Dolby TrueHD & ATMOS decode perfectly to 8 channel. Sounds as good as AVR doing it - DTS-MA, same story, decodes fine - MVC MKV's play great in full, frame-packed 3D (tested rip of 'Exodus: Gods and Kings' and 'Avatar') Two screenshots to share (the dropped frames is likely due to SMB vs. NFS?): - ATMOS test - 3D MVC MKV test Issues I'm seeing are stuttering (over wired SMB) with above & high bitrate test clips (Birds @ 90Mbps, & Jellyfish @ 100Mbps). I tried NFS, but it was worse. I have a Synology 1812+, and not sure how to use NFS properly. I believe I need to set Proto to UDP & rsize to 32768... but, don't know how to do this with my RPi2.

I think that's too high a bitrate for the VideoCore 4 GPU in the Pi/Pi2. It's not really a network or CPU issue on the Pi2, as neither are being maxed out (although CPU would most likely become the bottleneck on the Pi1, before the GPU). You can run "bcmstat.sh cxpd10" (included as standard in my builds) and you'll see the network is not being saturated by Jellyfish @ 90Mbps. I'm seeing an average of about 8-9MB/s over SMB for Jellyfish @ 90Mbps, with Pi2 1GHz CPU load @ 11% (35% for the single core handling playback and presumably network IO). This stutters, badly. A lower bit rate file, Jellyfish @ 60Mbps, has broadly similar network throughput and CPU load, but no stutter, so my opinion is that 60-70Mbps is the bitrate limit for the VC4 GPU and this limit is reached first before any other component in the system (ie. CPU, network). Overclocking the GPU (h264 etc.) might help a bit, but you're unlikely to see files with these kind of torture-test bit rates in normal viewing so the increased risk of instability probably isn't worth it (IMHO). RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - hdmkv - 2015-03-25 Thanks, I'll try overclocking. I'm not sure, but don't some 3D BD's reach bitrate peaks of around 90Mbps? Also, are there instructions somewhere on how to properly use NFS with the values I posted above?

Maximum Blu-Ray video bitrate is 40Mb/s (60Mb/s for MVC).

CPU, network). Yes agreed, this was my conclusion when I did my testing a while back over both NFS and SMB. 70Mbps was the limit over NFS with an Overclock.

You can play 80Mb/s jellyfish over NFS with an OS mount. The inbuilt libnfs is a bit slower.

Generally, deinterlacing in RPi looks strange. Like some pulsating in motion. One frame is just great, next creepy. http://dropmefiles.com/Q9WDw RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - slack3r - 2015-03-25 Some Omxplayer trouble with build #0323 and #0324 (Rpi1): player hangs after skipping backward, then I get a black screen trying to stop it. See the log: http://pastebin.com/zjzsGqcA Thanks P.s. Build #0321 is fine. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - da-anda - 2015-03-25 with #0323 I have serious issues when mmal renderer is used. As soon as there is any UI overlay playback is choppy with lots of drops. This doesn't happen with omxplayer. I tried with GUI update limit to 24fps and without any limit - same effect. MVC-3D playback is smooth with mmal and omxplayer RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - twelvebore - 2015-03-25 (2015-03-25, 02:49)hdmkv Wrote: Thanks, I'll try overclocking.

Look here for the NFS options: http://forum.kodi.tv/showthread.php?tid=217170&pid=1946803#pid1946803 There's info on how to do it through systemd on the OE wiki: http://wiki.openelec.tv/index.php/Mounting_network_shares#Systemd_NFS_sample_mount RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - SSC_Jarod - 2015-03-25 Hi, To test the Master HD Sound, what must i change in the Settings? I ve pssthrough activated and the i have a DD and DTS captable receiver. But in the Hobbit with Master HD it shows only DTS in my Receiver which is a DTS HD Receiver. Thx for Info @popcornmix: for Info: TAB 3D Movies are still with no picture in this build with option "Use Full HDMI modes for 3D" activated. The picture still not there if i turn off 3D on my TV while playing. Greetz J.

There are two deinterlace algorithms available: advanced - works like yadif2 but can only handle up to DVD resolution bob (fast) - simpler but works at 1080i. advanced produces a sharper image, but may have more motion artifacts. You can switch between them with OSD video menu. If you have a sample that doesn't deinterlace well, then upload (e.g. to google drive or dropbox) and I'll see if anything is wrong. As advanced doesn't work with 1080i, we fall back to bob on the firmware side. However doing that is less efficient that requesting the right algorithm from Kodi (where we can also request fewer buffers, which saves 3M of GPU memory). omxplayer has always done this, but this update makes dvdplayer/mmal do the same thing. |
