RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - fab67 - 2015-03-27 @Milhouse for info new ARM NEON optimized HEVC epel : https://ffmpeg.org/pipermail/ffmpeg-devel/2015-March/170781.html If you want to test with your build RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - popcornmix - 2015-03-27 (2015-03-27, 21:54)fab67 Wrote: @Milhouse for info We should already have that: https://github.com/popcornmix/xbmc/commit/1443e88975814c16016a714cc258dc8c3a858c5e RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - fab67 - 2015-03-27 Oh yes right, I thought that was a new one RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - popcornmix - 2015-03-27 (2015-03-27, 22:58)fab67 Wrote: Oh yes right, I thought that was a new one I think it's new to ffmpeg. I grabbed it from openhevc where the patches seem to appear first. Keep an eye out for any missing from newclock4 though (or any that have been updated). RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - Milhouse - 2015-03-28 New OpenELEC Isengard build #0327: RPi / RPi2 (Supercedes previous build) Code: # uname -a Based on tip of OpenELEC master (2886fa0b, changelog) and tip of XBMC master (3d02a51b, changelog) with the following modifications:
RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - MONSTA - 2015-03-28 Good job! VC1 1080p goes smoothly. Also gone the problem with progressive, as described here http://forum.kodi.tv/showthread.php?tid=221442&pid=1956784#pid1956784 . Dark City remux now played without stuttering and flickering. Interlace still gives artifacts. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - zaphod24 - 2015-03-28 Playback/rewind much better for me as well. Was surprised to hear that deinterlacing is bob for 1080 despite the setting being mmal-advanced which I saw in a previous post applies to a lower resolution. With the pi2 hardware (video chip being the same as original pi), will anything other than bob be possible for hd resolutions?

The advanced algorithm reads 3 fields of input and writes two frames of output for each video frame. That is just too much work for 1080p. The bob currently does a linear interpolate for the duplicated pixels. We could probably handle a cubic interpolate which would improve sharpness a touch. If anyone can suggest a deinterlace algorithm that only requires a single field, or perhaps a pair of fields from a single frame, then that may be feasible. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - MONSTA - 2015-03-28 And how about the upscaling? I mean lanczos, spline. Or Video Core is too weak for this?

Pi has high quality cubic scaling (Using the Mitchell Netravali kernel) for video. This is supported in hardware so doesn't have a cpu cost. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - MONSTA - 2015-03-28 Really? By default? Then super. Thank you. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - zaphod24 - 2015-03-28 Good info! If cubic interpolation is included in one of the builds I'd be glad to see if that gets rid of or minimizes the flickering/artifacts I'm seeing when watching 1080i60 live tv. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - doveman2 - 2015-03-28 I'm trying to get the DVB-T tuner working on my brother's RPI B. I've got the identical one on my RPI B and it works fine but I just get page timeout when I try and open http://192.168.1.83:9981 on his PC and the dmesg shows it's detecting different hardware for him for some reason, 'ITE 9135 Generic' for him, 'Kworld UB499-2T T09' for me We're both using the same remote receiver as well, the main difference is that I installed a Belkin USB Hub in his case, whilst I'm running with just the two built-in USB ports. The hub is cascaded and I found some issues with using the second part of the cascade, so I blocked off those ports with the case and he can only plug anything into the two ports attached to the first part of it. Even if he could make do with the RPI's two ports for just remote receiver and USB tuner, which isn't really practical as he needs at least one more for a USB stick for storage, it will be impossible for him to plug the tuner directly into the RPi as there's not room in the case. He was on a late February build, whilst I'm on 3 March, so I updated him to the latest #0327 but the dmesg still shows the same thing. I updated to #0327 and it still works fine here, although it did disable the PVR client and I had to re-enable that. My #0303 dmesg: http://pastebin.com/DtUJTZGR My #0327 dmesg: http://pastebin.com/xSP48upe His #0327 dmesg: http://pastebin.com/1ikk3UiB My #0303 kodi.log: http://pastebin.com/zK9x07Dg My #0327 kodi.log: http://pastebin.com/6tfKp0YP His #0327 kodi.log: http://pastebin.com/A0mGFgr6 His STB Freeview tuner is very much on it's last legs, so if I could get this working for him it would be great. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - Milhouse - 2015-03-28 @doveman2: Usual thing, you'll need to identify the last working build for your brother, presumably somewhere between late February and early March. RE: OpenELEC Testbuilds for RaspberryPi (Kodi 15.0) - cncb - 2015-03-28 I take it auto source resolution output (i.e. 1080i) is not possible like I asked about before? This would allow my TV or AVR to deinterlace which sounds like it would be better than what can be done on the Pi? |
