Thanks Nigel, Could you said me the brand and model of your Active DP to HDMI? We have use Startech DP2HD4K60S, and it works fine with other DP laptop output, so with the Firepro WX7100 windows sound options only show 2 channels. Could this be because the video card drivers are not updated?

Hi, We have a Denon AVR-3500H dolby decoder with hdmi, toslink and optical audio multichannel inputs. We like to extract 7.1 digital audio from Watchout Display, but it hasn't any audio digital outputs. It has a FirePro wX7100 video cards but we only can output 2 audio channels from they display port connectors. We have two options, install a sound card with toslink output (Creative Sound Blaster Audigy RX) or install a video card with hdmi and embedded audio 7.1. (MSI GeForce GT710 1GB DDR3 Low Profile) What solution do you recommend?

Hi Evanoferra, I transcoded the videos to HAP and the issue has not happened again at 7min 30s. Although now I have another problem that I have to determine. If you have mp4 videos, please transcode to HAP.

Thanks, I transcoded the videos to HAP. I'm testing the show. For the moment, not detected any issue.

Yesterday the issue happened again. Playback started correctly but after 7 min 30s the Watchout video outputs showed the Watchout Logo. The audio continued to play correctly. What else can I test? Diego

Thanks Hugo for your contribution.I don't know if that you say will help, because it fails after 7 minutes. The playback always starts well, but just in case, today I just added "-Delay 15" On Monday, I also changed the preroll to 10s and staggered for the 4 videos that would have to be played after the player fails. For the moment, no failure have been detected. Diego

Hi, I have a strange issue with 2 watchout displays. The show is played correctly, but when the displays computers are shutdown for some days (2-3 days) and then it are power on and load the show, it is played right for 7:30 seg and then the video reproduction fail showing the watchout logo on all screens of first watchout display computer and 2 seconds after the watchout logo is showed on all the screens of second watchout display computer. Note that when it occurs, it is always at this time. Audio and UDP events continue to play correctly. If I reload the show, the screens keep showing the watchout logo, so audio and UDP events continue playing correctly. To solve the issue, I must to restart both displays computers or relaunch the Watchout Display software. Once a restart has been performed after a failure, this failure does not occurs again until several days have elapsed without using the system. Any error was showing on displays computer. There aren't any error showed on log of watchout displays computer. I have these issue since several month ago. I have updated the Watchout version some times and the issue persist. Now the Watchout version is 6.4. Could anyone give me any idea why this might happen? It seems like a problem with video playback, but it only appears after several days without playing. Is there a video cache into Watchout that takes place after several days without playing? Can you think of any more tests I can do? Information about the system: Videos: mp4 Advanced Video Codec , Main@L5, CABAC: No, RefFrames: 2,GOP: N=1, Códec: avc, 25fps Display computers have 4 outputs each (1920x1200px resolution each output) SO: W 7 tweaking HDD: 2xSSD (one SO and other for Watchout app and medias) Attach show timeline image. Best regards

Hi guys, The issue is solved!! We install a Watchout software in a new Samsung 950 PRO Series 256GB PCIe NVMe - M.2 Internal (2Gb/s secuential read), change the power supply to ones with 1200W, update the bios and review all the points Thomas said. Now the display is able to play the six h264 videos a 30fps, 15Mbps and CPU use is about 20%-60%. Thanks to everyone

Thanks Tomas and Steve. I will check these points too.

Thanks. I attach a log picture from CPU and HDD recurses. First part is playing 6 diferents videos. Second part is playing 4 diferents videos. Red is % CPU Green/Pink read operations I will test to change ssd HDD , reduce 20% video resolutions and increment bit rates to 30Mbps. I will keep you informed. Diego Cónsul

Thanks Thomas, you are confirmed ours suspicions. Samsung EVO SSD is where are stored the videos, windows and Watchout software. Specifications about EVO SSD are "Sequential Read Up to 540 MB/sec" so is lower than 1.000Mb/s. (http://www.samsung.com/global/business/semiconductor/minisite/SSD/global/html/ssd850evo/specifications.html) Could you said me how to calculate the speed that I need? Other solution could be reduce the resolucion of the videos and scale it with watchout. What you think? Diego Cónsul

This is my first post. Hi to all! We have 11 projectors 1920x1200 60Hz and we need to show 11 diferents videos. One per projector. The display clusters are 2 computer with 6 outputs. The hardware specifications are: i7-5930K CPU 3,5Ghz (6 cores) with Corsair Hydro H60 16GB RAM Kingston HyperX Predator DDR4 4x4GB 2133Mhz Main board Asus X99-Pro Graphic Card: Sapphire FirePro W9100 (FireGL V) HDD SSD SAMSUNG EVO 250GB (MZ-75E250) HDD 1TB ST1000DM03 Power supply Tuniq 950W 80+ Windows 7 64bits Watchout 6 All outputs from FirePro are forced edid to 1920x1200 60p. The resolutions of the each video are: Projector10 (Out 1 Cluster1): 1766x1200px (video10) Projector11 (Out 2 Cluster1): 1248x1200px (video11) Projector1 (Out 3 Cluster1): 1508x1200px (video1) Projector2 (Out 4 Cluster1): 824x1200px (video2) Projector3 (Out 5 Cluster1): 1270x1200px (video3) Projector4 (Out 6 Cluster1): 864x1200px (video4) Projector5 (Out 1 Cluster2): 1564x1200px (video5) Projector6 (Out 2 Cluster2): 1244x1200px (video6) Projector7 (Out 3 Cluster2): 1720x1200px (video7) Projector8 (Out 4 Cluster2): 860x1200px (video8) Projector9 (Out 5 Cluster2): 1858x1200px (video9) The problem is that the display clusters are not able to play all videos smoothly. We are codec the videos in some formats. 25Fps/30fps; 4:2:0/4:2:2; baudrates of 2Mbps,5Mbps, 15Mbps; in mpeg2/mp4/h264 but it can't play six videos per cluster. We are only able to play 3 or 4 videos ok. For example: mpeg2 30fps 4:2:0 5Mbps the cluster1 is be able to play smoothly video10, 2, 3 & 4 on it's projector. If we show the video10 on projector11 & 1, the system play smoothly too. If I change the video of projector 1 from video10 to video1; the cluster1 not play smoothly. The videos are playing with breaks. At the same conditions the cluster2 is be able to play smoothly video5 on projector5, video8 on projector 8 and video 9 on proyector 5, 6 ,7 & 9. Anybody can help us. What's is the problem? Any suggestion? Thanks in advance.
