Watching AV1 videos on Emby applications (Android and MacOS) without server encoding (Direct Play) is really bad. Playing AV1 videos works really smooth in browsers on the same devices (Samsung Galaxy S20 and MacBook Pro with i7-8850H).

Hi, I'm noticing that whenever I set quality to auto, it direct plays but the video stutters every 2 seconds. If i manually set the bit rate to match the video bit rate it works smoothly.. but setting it to auto causes it lag or buffer every 2 seconds on certain videos. If i seek then it struggles to play it. Sometimes auto picks up the wrong quality setting entirely like choosing 720p 4Mbps for a 10Mbps bitrate.. I'm not sure what's wrong with my config. Any help would be appreciated. I'm using emby server 4.8.10 and I have an NVIDIA GPU. I'm attaching logs for reference when this happens.. embyserver.txt ffmpeg-transcode-c32e80a8-e89c-448a-b8e3-23d0dffdf933_1.txt

I'm running emby server on a linux kubernetes cluster with 2 NVIDIA GPUs. On any device (Fire stick, ipad, phone or browser) for several videos if i seek the stream forward or backward even by a little bit, the video starts stuttering every 2 seconds. There's no recovery from that. Even if i exit the app and come back and try to resume the lag remains. Then I tried fiddling with the quality settings - I don't need to reduce to the point of transcoding. I just kept swapping between Auto and 1080p - 10Mbps. The video is a 1080p H264 and bitrate of 8mbps. Finally after multiple tries it continues playing normally at 1080p - 10Mbps still as a Direct play. The server dashboard says the stream is direct play throughout. I'm attaching some logs. The logs are while playing on the ipad. If you would like me to get you logs for some other device, let me know and i would be more than happy to pull them. ffmpeg-remux-seek-recov.txt embyserver-seek-recov.txt ffmpeg-remux-seek.txt embyserver-seek.txt

Hey there, I was just wondering if you guys can suggest any settings, tweaks, hacks, plugins, etc. for pushing the overall streaming performance when multiple users stream media. When I start a 1080p mkv movie ( in this case with dts) which triggers transcoding at 10 mbps the movie runs like it should... but as soon as another user starts streaming a movie like this, it sadly turns into a wallpaper-picture-show. While the overall performance of my server should be more then enough (100+mbit bandwidth, 2 cores, 32gb ram) there seems to be a pretty tight performance bottleneck somewhere and I hope you guys can help me fix that. My goal is to be able to stream for up to 5 users (from different sources like browser, fire stick, apple tv, and so on) at the same time without any lags. what do I need to know and understand here? how to manage this? how/what to tweak? what topics should I look deeper into? Any input on this topic is greatly appreceated for I am new to this software. Thanks in advance Soki
