jfarre20 3 Posted May 21, 2014 Share Posted May 21, 2014 Are you sure it's not a 5.1 to stereo conversion or something like that ? (could depend on loads of things, Not sure WMP is the best test program for a baseline) Also i think the dev's are gonna need a media-info from that file so If you would not mind attach that a swell (Just in case) WMP and Media Player Classic Home Cinema sounded the same - So, I think it is producing the proper sound. Also, when I tried playing the transcoded .webm with WMP - it sounded weird. There is something wrong with the transcoder or the transcoder settings. I have also tried the web interface on older video files that I know aren't in 5.1 - they still sound wrong. The audio plays normally through mediabrowser classic on WMC and through the mediabrowser 3 app on windows - however, these do not require transcoding. *Added the media-info to the main post Link to comment Share on other sites More sharing options...
Luke 36997 Posted May 21, 2014 Share Posted May 21, 2014 in advanced -> transcoding, try setting the audio boost value to 1 Link to comment Share on other sites More sharing options...

jfarre20 3 Posted May 22, 2014 Author Share Posted May 22, 2014 (edited) UPDATE: Solved the issue -- Look at the bottom of this post for what I did to fix it. I noticed the audio quality on the web player sounds off. I'm not sure how to describe the issue, it almost sounds like reverse stereo. I recorded the issue and posted it to YouTube Look at the VU meter as it plays through, you will notice that the transcoded audio playback's left and right channels are slightly out of sync. I have tried different source video formats, adjusting the quality options in the server software, as well as playing the .webm file directly - the audio issue persists. I even tried updating ffmpeg manually, it still sounds wrong.

Beardyname 194 Posted May 22, 2014 Share Posted May 22, 2014 WMP and Media Player Classic Home Cinema sounded the same - So, I think it is producing the proper sound.

jfarre20 3 Posted May 22, 2014 Author Share Posted May 22, 2014 (edited) I wonder if this could be an issue with the audio sample rate and bit depth. On my windows client, I have my audio format set to 24 bit - 48000HZ (Studio Quality). The server doesn't have any audio output device installed, although I'm not sure how that would affect it. I'll try changing the format and see if that fixes it. Update: Nope - still weird sounding. Edited May 22, 2014 by jfarre20 Link to comment Share on other sites More sharing options...
Solution jfarre20 3 Posted June 13, 2014 Author Solution Share Posted June 13, 2014 (edited) Fixed it - Installed Shark007 Codec Pack, updated server to latest stable release, rebooted machine.
