kbbles 3 Posted April 16, 2023 Share Posted April 16, 2023 hi, I've been trying to figure out why nearly everything gets transcoded to h264 in Firefox and that's because the log shows &VideoCodec=h264 and no other codecs. is this normal? I downloaded some youtube videos and vp9 seems to direct-play, but nothing else regardless of container or codec. for example, I have an av1 SVT movie as a .mp4 and even that's getting transcoded. the client in question is using a 3080 ti graphics card which supports av1 decode, but emby doesn't seem to recognize that regardless of platform. on Chromium browsers and Emby Theater for Windows, they all transcode as well, with the logs saying &VideoCodec=h264,h265,hevc so I'm not sure what could be going on. I poked around online and found something called dav1d, if I can put that on Emby running on my Docker container on Unraid that would be awesome, but I can't seem to find any guides about it. thanks in advance!

kbbles 3 Posted April 16, 2023 Author Share Posted April 16, 2023 to add: my partner has a windows PC with a 3060 ti graphics card, and the exact same thing is happening to her Link to comment Share on other sites More sharing options...
Happy2Play 8282 Posted April 16, 2023 Share Posted April 16, 2023 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...
kbbles 3 Posted April 16, 2023 Author Share Posted April 16, 2023 sure thing! sorry about not providing all of this sooner. if I can provide anything else, please let me know! embyserver.txt ffmpeg-transcode-991514b9-a19b-48e3-aa08-7da3983a4d57_1.txt Link to comment Share on other sites More sharing options...
Happy2Play 8282 Posted April 16, 2023 Share Posted April 16, 2023 Will have to look but to my knowledge FF provides the least amount of codec support comparted to other browsers. So mileage will vary per browser. Where you would get or support from Desktop ET. Link to comment Share on other sites More sharing options...
kbbles 3 Posted April 16, 2023 Author Share Posted April 16, 2023 so I've tried this on Edge (chromium), Brave (also chromium), Firefox and Emby Theater on Windows (Microsoft store) and none of them are doing av1 playback. FF logs only show h264 like that, the other ones I mentioned show h264/h265/hevc. I can post the logs for one of the other ones if that's any help!

Luke 37069 Posted April 16, 2023 Share Posted April 16, 2023 Hi. Did you explore the stats feature in the video player to learn why it was transcoding? Link to comment Share on other sites More sharing options...
kbbles 3 Posted April 16, 2023 Author Share Posted April 16, 2023 the test file in question just says it's transcoding. is there some way to find out why using these stats? Link to comment Share on other sites More sharing options...
Solution Luke 37069 Posted April 16, 2023 Solution Share Posted April 16, 2023 OK so this is one of those situations where an audio conversion also results in a video conversion, because we can direct play av1 but we can't put it into the transcoding protocol.

kbbles 3 Posted April 16, 2023 Author Share Posted April 16, 2023 oh okay, that makes a lot of sense! so I should re-transcode it to av1 but this time transcode the audio to ac3 then? Link to comment Share on other sites More sharing options...

But Firefox does not support ac3. Link to comment Share on other sites More sharing options...
kbbles 3 Posted April 16, 2023 Author Share Posted April 16, 2023 yep just found that out, Theater direct-plays with ac3 but Firefox would need aac. I don't mind using Emby Theater, just wish it supported custom fonts & audio compression - but that's for another thread lmao going to mark this one solved, thanks! 1 1 Link to comment Share on other sites More sharing options...
