Struggling with Transcoding Audio

Hello, I have Serviio running on a Windows 7 x64 box (file server in the basement).

I have two clients that I'm trying to get working. One is a WD TV Live, which I haven't played around with yet. (I gave up on sharing files with Windows 7... its a conspiracy!)

The other is an iPhone 5 with IOS 6.1.4 running 8player. 8Player is recognized as 'Generic'.

Video playback is just fine, but no audio. Its running over local WIFI.

I picked up the latest ffmpeg, did a probe of one of the files not working;
Input #0, avi, from 'M:\Shares\Video\SciFi\Star Trek II - The Wrath of Khan - CD1.avi': Metadata:
encoder : Nandub v1.0rc2
Duration: 00:58:00.61, start: 0.000000, bitrate: 1666 kb/s
Stream #0:0: Video: mpeg4 (XVID / 0x44495658), yuv420p, 640x272 [SAR 1:1 DAR 40:17], 23.98 tbr, 23.98 tbn, 23.98 tbc
Stream #0:1: Audio: ac3 ([0] [0][0] / 0x2000), 48000 Hz, 5.1(side), fltp, 448 kb/s


Serviio is configured to with transcode enabled, Produce Best Video Quality, Downmix to Stereo.

I really have no clue what is going on. And on a personal note, I'm kinda miffed that there isn't more diagnostics about what might me going on. I wish Serviio could tell me what it thinks its doing, or if its confused.

Help me Obi Wan. You're my only hope!

Re: Struggling with Transcoding Audio

8player doesn't support AC3 Audio (well, some people have reported it does, but it certainly doesn't for me, so I suspect it may be a regional thing).

To overcome this, add a profile to your profiles.xml file to transcode AC-3 audio. This is my profile for 8Player:

  Code:
<Profile id="iPad8" name="iPad 8Player" extendsProfileId="1">
   <Detection>
      <HttpHeaders>
         <User-Agent>.*8player.*</User-Agent>
      </HttpHeaders>   
   </Detection>
   <Transcoding>
      <Video targetContainer="mpegts" targetACodec="mp3" aBitrate="384">
         <Matches container="*" aCodec="ac3" />
         <Matches container="*" aCodec="dca" />
      </Video>
   </Transcoding>
   <ThumbnailsResolution>HD</ThumbnailsResolution>
</Profile>
This profile will transcode both AC-3 audio and DTS audio. Video is simply remuxed.

Add this profile to the end of your profiles.xml file just before the last line (containing </Profiles>). Restart your PC to load the new profile. After that the new 8Player profile will auto detect and your audio problems should be no more.

ps. "I wish Serviio could tell me what it thinks its doing, or if its confused." In this case its not really a Serviio issue, but doing a Serviio detailed log will generally tell you what Serviio is doing.
