<html><body>Hello,<br />I'm having difficult problems with playback in the frontend version 0.28.1-3 and would love some help please!<br /><br /><br />I've been building a new media PC which will mainly be used for MythTV. I deliberately chose to use intel graphics, to avoid the trouble of binary proprietary drivers, for lower power consumption and as no additional noisy cooling fans are required.<br /><br />I first tried using VDPAU but the frontend refuses to work with it, erroring out each time with an unhelpful A/V sync error. (Packages installed include libva-vdpau-driver-0.7.4-14, libvdpau-va-gl-0.4.2-2 & libvdpau-1.11-3 )<br /><br />So I switched to VAAPI, despite it lacking deinterlacing. I'm still having playback problems with stuttering, especially with live TV. My PC also has Intel HD audio (Realtek ALC892).<br /><br />Although playback works, when I enable debug logging I see multiple occurrences of both:<br /><br /><date> <time> I Player(0): Waiting for video buffers...<br /><br />and:<br /><br /><date> <time> I Player(0): Video is 3.54437 frames ahead of audio,<br /> doubling video frame interval to slow down.<br /><br />I've searched the internet, including archives of this mailing list, and these problems have previously been called driver issues. Kodi doesn't seem to have any issues though. I'm running Fedora 25 with a recent kernel which should contain the latest stable Intel drivers anyway. I'm not sure what I can do? Do you have any ideas, please?<br /><br />Thanks in advance!<br />evade.<br /><br />---------------------------<br />Relevant packages:<br /><br />mythtv-frontend-0.28.1-3.fc25.x86_64 (and local backend of the same revision)<br />Kernel 4.11.6-201fc25.x86_64<br /> (Using VAAPI: Driver : Intel i965 driver for Intel(R) Skylake - 1.7.3)<br />libva-intel-driver-1.7.3-2.fc25x86_64<br />xorg-x11-drv-intel-2.99.917-26.20160929.fc25.x86_64<br />---------------------------<br />Relevant devices:<br /><br />Intel H170M chipset, Intel i5-6500 CPU with HD Graphics 530<br />00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) (prog-if 00 [VGA controller])<br /> Subsystem: Gigabyte Technology Co., Ltd Device d000<br /> Flags: bus master, fast devsel, latency 0, IRQ 126<br /> Memory at ee000000 (64-bit, non-prefetchable) [size=16M]<br /> Memory at d0000000 (64-bit, prefetchable) [size=256M]<br /><...><br /> Kernel driver in use: i915<br /> Kernel modules: i915<br /><br />Intel "HD Audio" (Realtek ALC892)<br />00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)<br /> Subsystem: Gigabyte Technology Co., Ltd Device a182<br /> Flags: bus master, fast devsel, latency 32, IRQ 128<br /><...><br /> Kernel driver in use: snd_hda_intel<br /> Kernel modules: snd_hda_intel<br /><br /></body></html>
