(This is a spin-off from this thread)

Having done a little more research, it looks like MC is capable of transcoding formats, but not channels.

I have lots of video files that I'm trying to play using MC16 as a DLNA server and a DirecTV box as the renderer/player. Most of the files are in MP4 containers, but several are MKV, AVI, MOV and even FLV. In trying to get the MP4 files playing, I discovered that MC is able to convert the video into MPEG2, but is only able to convert files with 2 channel audio. It doesn't seem to matter what format the audio streams are in--MP3, AAC, AC3--if it's a 2-channel stream, the file converts and plays. If it's a 6-channel file, playback fails.

Are there any settings I'm overlooking in trying to get files with 6-channel audio streams to play back?

Try tweaking the ffmpeg.xml (upnpdvd lines) to set it to two channel?

[bspachman]

Tried adding the parameter "-ac 2" to both the upnpdvd and the upnp_mp2_med lines. Restarted the media server, but same symptoms resulted. I also tried adding the parameters "-acodec mp3" and "-ab 160k" with no joy.

Thoughts?

The map options selects the input stream to encode. The encoding options specify the output.
I haven't tried this but from reading this doc, I think that it should work:

Did anyone get this working? I'm having similar problems where the directv box can play video files, but it says it is unable to play the audio. I'm not clear what I need to do to get this working.

I never did get this working with MC16, and I haven't tried yet with the MC17 beta. However, nothing I've read so far leads me to believe there have been changes yet in this area.

Do you know what kind of video files you are trying to play? Container (mp4, avi, mkv) and Codecs (h264, acc, mp3, ac3) and how many streams the files contain?

17 uses internal conversion (only when set to mpeg2/dvd). I'd expect different results given that. It'd be interesting to see if that changes anything for you.

Great & Interesting news! I'll give it a try as soon as I get a chance!
