centuryx476 8 Posted January 22, 2020 Share Posted January 22, 2020 (edited) Hello, I have started ripping my collection. But as a test I wanted to see how the server will handle the playing of a movie.I ripped a standard blu ray to Container: .mp4 Bitrate: 8.6 Mbps Video Codec: H264 Audio Codec: AC3 @ 640 kbps Audio channels: 6 Sample Rate: 48000 Hz When I play the movie via my web browser the CPU jumps to 50% +/- I checked the logs and it appears to be transcoding the audio of the movie. This only happens when I watch the movie via a web browser. If I watch the movie via Roku or my phone app then the CPU hovers around 1% to 2% usage which is what is expected. I thought AC3 is a pretty standard codec ? why is it being transcoded for web browser viewing ? What is the recommended Audio Codec to use then for emby ? Mind you I value my audio quality Thank You Edited January 22, 2020 by centuryx476 Link to comment Share on other sites More sharing options...
rechigo 293 Posted January 22, 2020 Share Posted January 22, 2020 (edited) I thought AC3 is a pretty standard codec ? why is it being transcoded for web browser viewing ? Thank You AC3 isn't supported in basically any browser nowadays due to licensing. I would recommend shooting for AAC as the majority of browsers can play back AAC directly Sent from my SM-G973U using Tapatalk Edited January 22, 2020 by rechigo Link to comment Share on other sites More sharing options...
Luke 37009 Posted January 22, 2020 Share Posted January 22, 2020 Actually Microsoft Edge on Windows supports AC3, but it appears to be Windows only, not Edge on other platforms. Link to comment Share on other sites More sharing options...

I haven't checked my stats for nerds before to see if it direct streams Sent from my SM-G973U using Tapatalk Link to comment Share on other sites More sharing options...
Luke 37009 Posted January 22, 2020 Share Posted January 22, 2020 Last i tested ac3 with it,yes, but it's been at least a few weeks since i did that. Link to comment Share on other sites More sharing options...
centuryx476 8 Posted January 22, 2020 Author Share Posted January 22, 2020 (edited) Wow, I seem to be a little behind and I didn't know that AC3 was not generally supported in web browsers. For some reason I was under the impression that AC3 was the more advance and proper audio codec. But it seems not, So for emby, the best settings is Container: .mp4 Audio Codec: AAC Thank You Edited January 22, 2020 by centuryx476 Link to comment Share on other sites More sharing options...

Microsoft only did because they were looking for ways to create more interest in Edge when it first launched. Link to comment Share on other sites More sharing options...
pwhodges 1523 Posted January 22, 2020 Share Posted January 22, 2020 The last patent covering AC-3 expired in March 2017. Paul Link to comment Share on other sites More sharing options...
centuryx476 8 Posted January 22, 2020 Author Share Posted January 22, 2020 (edited) I'm going to encode it again this time with AAC. I'm sure this will 100% fix the issue. The encode will be done in about an hour. Also, thank you all for this wonderful info on AC3 license info that I totally should of looked up before posting.... Thank You again Edited January 22, 2020 by centuryx476 Link to comment Share on other sites More sharing options...

The encode will be done in about an hour Thank You You shouldn't have to reencode the whole file just to change the audio codec. You could use FFmpeg to remux it or even the Emby convert feature with the right settings, that way you're only reencoding the audio Sent from my SM-G973U using Tapatalk Edited January 22, 2020 by rechigo Link to comment Share on other sites More sharing options...

Happy2Play 8242 Posted January 22, 2020 Share Posted January 22, 2020 You can go to html5test.com to see what your browser supports. 1 Link to comment Share on other sites More sharing options...
rechigo 293 Posted March 16, 2020 Share Posted March 16, 2020 Okay, in the dev branch at least, it appears microsoft brought back support for AC3 (Dolby digital). This might make this browser the preferred web client as it should be able to direct play most common formats. Link to comment Share on other sites More sharing options...
