<div dir="ltr"><div><div>Hey everyone.<br><br></div>There are several (three?) threads going now about using the ECS LIVA as a MythTV frontend... but I'm going to take it a different direction. :-) I'm here to say that the LIVA also works quite well as a *BACKEND*, and amazingly - as a backend / frontend combo as well !!<br><br><br></div><div>I'm running Gentoo, so I've been tacking my findings on to SiliconFiend's ECS LIVA How-To thread on the Gentoo forums as I go along:<br><a href="http://forums.gentoo.org/viewtopic-p-7675300.html">http://forums.gentoo.org/viewtopic-p-7675300.html</a><br><br><br></div><div>Short list of my system hardware configuration:<br>-----------------------------------------------------------------<br></div><div>ECS LIVA (BAT-MINI v1.0)<br></div><div>$109 model with 32GB eMMC / 2GB RAM (NO reason to spend more on the 64GB models)<br></div><div>3x older USB ATSC digital tuners with multirec enabled<br></div><div>1.5 TB USB 3.0 2.5" portable (bus powered) hard drive<br></div><div>USB MCE-style IR receiver<br></div><div>USB RF wireless keyboard/trackpad combo<br></div><div>WiFi on the LIVA (no hardwired ethernet)<br></div><div>Audio via the analog output<br></div><div>1080P display connected via HDMI<br></div><div>USB slim DVD drive<br></div><div>-----------------------------------------------------------------<br><br></div><div>Special hardware note: I'm using a LIVA from the SECOND (or later) production run of the FIRST generation of
the LIVA. The first/first had a dual-core N2806 CPU, while the second run, after a few hundred were produced, changed to the dual-core N2807 CPU. This is also *not* the second-generation "ECS LIVA X", which is supposed to launch in a week or so at CES 2015, with rumors pointing to a quad-core N2940 CPU for that model. <br></div><div><br><br></div><div>Software configuration:<br>-----------------------------------------------------------------<br>Gentoo (stage 3 install, 'native' architecture, everything built from source with no binary packages used)<br>Linux kernel 3.17.7-gentoo, manually configured to be absolutely as minimal as possible.<br>Pure 64-bit configuration (no multilib, no 32-bit emulation)<br>Root partition on eMMC formatted as ext4, Data partition on spinning disk formatted as JFS.<br>media-tv/mythtv-0.27.4_p20141018 (~amd64 masked)<br>x11-drivers/xf86-video-intel-2.99.917 (~amd64 masked) <br>x11-libs/libva-1.4.1 (~amd64 masked)<br>x11-libs/libva-intel-driver-1.4.1 (~amd64 masked)<br>OpenGL painter, vaapi playback profile in MythTV frontend<br></div><div>4GB swap space on the USB hard drive ONLY (My system rarely uses it, and I have it on the spinny disk to avoid premature wear & tear on the eMMC.)<br></div><div>Entire software install uses < 5GB of space on the eMMC, climbing to maybe 9GB with all of the backup copies of the package sources. (That's why the 64GB model is unnecessary)<br></div><div>Import of database from previous backend, with ~4 years of daily use recording history<br></div><div>Import of ~1.4 TB of previous recordings<br></div><div>-----------------------------------------------------------------<br><br><br></div><div><br></div><div>I've found that running a current kernel and current Intel graphics drivers are absolutely crucial to the performance and stability. The system as configured doesn't even flinch with HD Live TV... and does just fine watching live TV with a second background recording as well. If I spool up all three tuners recording three shows from separate stations (on separate multiplexes), I get some minor glitching in the playback if I'm watching a fourth recording at the same time. Under normal use, the frontend remains very responsive, skipping around in recordings is nearly immediate, etc - you would never guess from using it that it was such a low spec machine. My wife is watching a previously recorded 1080i New Years special right now, with two more recording in the background, and the CPU stats are 11% user 15% system, ***59% idle*** and 15% wait. <br></div><div><br><br></div><div>I was planning to order a second one of these to play around with, but I genuinely don't need to! It took a long time to get set up, but I'm pretty darn impressed with how capable this thing is, especially at the price point and with such astonishingly low power usage and purely passive cooling. <br></div><div><br><br><br></div><div>Any questions, ask away and I'll do my best to answer. But I wanted to get the word out that the LIVA was in fact capable as a backend AND as a BE/FE combo. :-)<br><br></div><div>Special thanks to Karl (SiliconFiend) for the early setup/documentation work for Gentoo, and to all of the MythTV devs that made this possible!<br><br></div><div>- Dave<br></div></div>
