MediaBrowser not playing H.265 4K material
Posted: Mon May 28, 2018 11:45 pm
I've started picking up UHD Blu Ray movies when I can find a title I like and the price isn't ridiculous. So far, I have Close Encounters, Dracula (1992), Independence Day, and The Fifth Element. I also have a number of 4K demo clips I've downloaded from online, mostly H.265 but a few H.264 video. Audio runs from 2 channel AAC to 7.1 TrueHD and DTS Master Audio. I'm still tweaking the Roku profiles, trying to get them to all play, but today I decided to try MediaBrowser, to see what might play. Unfortunately, out of 19 videos I can only get one to play at all, and it was really lousy.
I logged into my test server so I could watch what the CPU load was, and was astonished to see FFMPEG jump to over 1 GB of memory in use while trying to transcode the video. When I switched to a normal DVD rip, the memory in use dropped to under 20 MB. But the UHD video never actually begins playing. I let it sit from over a half hour, just to see if it were some severe buffering, but no joy.
Log attached. The computer I was running MediaBrowser on is 192.168.0.35, a Windows 10 Home PC. I was using both Edge and Firefox, as I knew neither of them had any ad blocking or other add-ons. I do have such in Chrome, so I don't like to use it for testing. The one file that did at least play (with lots of pausing) was titled Sharp Saturn Rings.MP4. I had re-encoded it to H.264 L5.1, so still 4K but not HEVC. I have another AVC wtih High 10L5.1 in an MKV container. This one too plays, but with no video, only sound. Any video with H.265 just never complete loading. The transport controls never appear.
And for the two video that will play, I see peak video bitrates of almost 250 Mbps. According to MediaInfo, the file has a peak bit rate of 119 Mbps. Why is FFMPEG doubling the bitrate during conversion?
Another issue:
See some strange errors in the log pertaining to a RenderManager error. The IP address reported there is 192.168.0.52, which is my Samsung JU7100 TV. Rarely even use the TV as the player, so no idea why so many errors with it.
