RE: OpenELEC Testbuilds for RaspberryPi Part 3 - popcornmix - 2014-04-25 (2014-04-25, 01:24)da-anda Wrote: TV is switching into 1080p@50, but I'm not sure if this is correct, because XBMC is reporting the video format as 25fps (pal DVD) and 1080p@25 (which my TV is also supporting) might be the more correct resolution? xbmc deliberately chooses the highest multiple of the video framerate, so this is expected. I did include a patch (on newclock3) to pick the lowest multiple as it is a little cheaper to do, but there some reports of TV's not supporting 25/30 Hz properly and the patch was removed.

Btw - I manually switched GUI res to 1080p@25 and disabled refresh rate adjustment for video playback, so that DVD will play on the 25Hz refresh rate, but I think I also noticed those random jumps there (no AV sync enabled for testing). It was late and I was tired, so my eyes could have tricked me. As for the AV syncing - which is the best mode to use for the PI or this particular case? I was trying audio clock which seemed to work fine, did only a short test though. And do you know if AV sync will only kick in if refresh rates don't match, or is this thing always on once enabled in settings?

I was trying audio clock which seemed to work fine, did only a short test though. And do you know if AV sync will only kick in if refresh rates don't match, or is this thing always on once enabled in settings? My understanding is that with dvdplayer, "adjust display refresh rate..." just switches to the best refresh rate. If your file has perfect timestamps (e.g. 24fps/48kHz stream contains exactly 24 frames per second and 48000 audio samples) *and* your graphics card's video clock is synchronous to your sound card's audio clock, then everything should be good. However neither of these conditions are generally true. You need another feedback path that detects drift in audio/video and compensates. On dvdplayer you need to enable "sync playback to display". That gives 3 sub-options: audio clock : The clock just jumps in software. I believe this is the same as having "sync playback to display" disabled and that will still have video judder video clock (resample audio): For non-passthrough audio is resampled to fit in. Video should be smooth, but audio quality may be (marginally) worse. For passthrough drop/dupe occurs. video clock (drop/dupe audio): audio frames are dropped/duplicated to fit. Video should be smooth, but audio quality may be worse Resample is more expensive in cpu than drop/dupe but is probably less audible. omxplayer has an additional sync scheme where it has a separate PLL for the HDMI video clock, and can maintain sync without harming audio or video. This is only enabled when "adjust display refresh rate..." is enabled, so manually choosing 24Hz won't be as smooth as automatically switching. This scheme is much better than the others, and everyone should enable it. omxplayer can also support audio resampling. If "Sync playback to display" is enabled (with any sub-options) it will behave like dvdplayer in "video clock (resample audio)" mode. This can be useful if you get audio dropouts in "adjust display refresh rate..." mode.

I've recently added it and my CEC broke afterwards, removing that line again fixed it for me. TV powers up again if I plug in the RPi though... RE: OpenELEC Testbuilds for RaspberryPi Part 3 - Milhouse - 2014-04-25 New OpenELEC Gotham build: #0425 (Supercedes previous build) Code: # uname -a Based on tip of OpenELEC master (ad14731, changelog) and tip of XBMC master (110396e, changelog) with the following modifications:
FIQ FSM enabled as default in kernel, plus a couple of other FIQ FSM fixes.

Please ask the OpenELEC developers so that it has official support. Open an issue on github. RE: OpenELEC Testbuilds for RaspberryPi Part 3 - da-anda - 2014-04-26 Ok, did some more tests playing DVDs, and the only way I get stutter free playback is by using omxplayer. Any AV sync setting still caused frame drops every few seconds. Tested this with a vertically scrolling text (like end titles/cast). Will use this DVD to create debug logs now RE: OpenELEC Testbuilds for RaspberryPi Part 3 - tuxen - 2014-04-26 (2014-04-25, 13:28)popcornmix Wrote: omxplayer can also support audio resampling. If "Sync playback to display" is enabled (with any sub-options) it will behave like dvdplayer in "video clock (resample audio)" mode.This explains a few things I scratched my head about with non standard framerates/time stamps. @da-anda: out of curiosity with another platform, try setting settings->settings->audio output "output configuration" to best match instead of optimized.

These seem to play fine, as do the flac files you've linked to previously. RE: OpenELEC Testbuilds for RaspberryPi Part 3 - Mister XY - 2014-04-26 How can i use this WakeOnLan boot support? |
