burnchar 2 Posted October 26, 2021 Share Posted October 26, 2021 See attached video. All Emby videos played in Edge are extremely jittery, as if it plays frames in this order: 1, 2, 3, 4, 5, 1, 6, 7, 8, 9, 10, 6... All Emby videos played from FireFox are not jittery, they are transcoded and have frequent pauses because my server is a Xeon 3060 from the Core2 era. Emby documentation says that Emby transcodes only when necessary. This is false. All videos play just fine over local network using Media Player Classic. Emby through AndroidTV works without issue. I do not know if Windows 11 has anything to do with the two bugs, but I know they are bugs. Client specs: Windows 11 on Microsoft Surface Pro 8 Core i5-1135G7 / Intel Iris Xe Server's and client's CPU and GPU usage minimal Not transcoding (if it were, that would be a different bug) Same on two different wireless networks, wifi5 and wifi 6 Distance from wireless router makes no difference Server /network specs: Intel Xeon 3060 Intel gigE Ubiquiti 16-port GigE switch, latest generation Routers: Linksys EA8300 Wifi 5 router and C4000XG Wifi-6 router 5-drive RAID5 array on 3Ware Escalade 9750-8i RAID card IMG_3769.MOV Link to comment Share on other sites More sharing options...
GrimReaper 3308 Posted October 26, 2021 Share Posted October 26, 2021 Are those HEVC encodes you're trying to play? 1 Link to comment Share on other sites More sharing options...
Luke 37098 Posted October 26, 2021 Share Posted October 26, 2021 Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. thanks ! Link to comment Share on other sites More sharing options...
Luke 37098 Posted October 26, 2021 Share Posted October 26, 2021 Quote Emby documentation says that Emby transcodes Actually this is true, but remember that in a web browser, it's not about what the device supports, it's about what the browser supports. Have you looked at what Firefox supports? It's pretty limited compared to Chrome or MS Edge. Link to comment Share on other sites More sharing options...

I thought my second experiment, a very old TV show, would be in MPEG2 or something, but it, too, is in HEVC. I re-tested a few samples that use MPEG-2 and AVC and they work perfectly. Is the browser not capable of HEVC? Link to comment Share on other sites More sharing options...

Solution Carlo 4330 Posted October 26, 2021 Solution Share Posted October 26, 2021 From my playing around with my HEVC collection I've found MS Edge to be the web browser for media playback from my Emby server. But I'd still choose to use Emby Theater on a PC vs browser if possible, just because it's a much more robust client. 1 Link to comment Share on other sites More sharing options...

Luke 37098 Posted October 27, 2021 Share Posted October 27, 2021 Chromium based browsers support the mkv container, and then on Windows, Edge also adds ac3 and hevc support to that, so that really helps it stand out as the best browser to play with. 1 Link to comment Share on other sites More sharing options...

There's not much we can about that other than transcode it, which you've already said you don't want. Link to comment Share on other sites More sharing options...

If I could edit my original post, I'd cross out: ", but I know they are bugs". I suppose they are technically bugs, just not of Emby. I apologize for my presumptuousness; I thought I knew what I was talking about because I am a software engineer and I have encoded thousands of videos, digging into settings and encoding methods in great detail. I did not know, however, that the browser is designed to need all its own decoding support rather than just using the OS's registered media handling. I wonder what led to that design choice. I'll use Emby Theater and eventually get a faster server with video hardware that can transcode. Not an Emby problem. Nothing to see here. Link to comment Share on other sites More sharing options...

My question is why does anyone play files in a browser? I can understand if you are watching on a PC without premier but if you are then you are getting much lower quality video to begin with as there is no upscaling like when watching on a TV. I test all my encodes in the browser app to make sure they play fine before I load them to an emby drive and on many the qualty is not good with jagged edges etc but when played on a TV they look fantastic. Watch Netflix on a computer and compare it to the TV.....same thing. It would only make sense to me to watch in a browser if you didn't have a TV at all because any new TV is going to have better playback support and even if it's an old TV a $25 Firestick or Roku fixes that.

Ronstang 202 Posted February 18, 2022 Share Posted February 18, 2022 I understand that but accessing one from a TV is not and wouldn't make sense anyway with better options for emby.....and like I said, if you are watching on a computer monitor you are getting crap quality......OOPS.....I'm old, many people use a TV as a monitor now so I can see where that would be OK.
