Twonky Forum

Hi community,

already for a couple of days I am trying to get transcoding in TwonkyServer 8 working. And I got a couple of questions I hope you answer.
By the way: I tried to use the search function but every single term I tried, the board replied with "the term is too common". Maybe some admin could fix that...

Situation:
-Windows 8 PC with installed Twonky 8.
-Grundig 50 VLE 921 BL smart TV. (Friendly name: Inter@ctive)
The handbook says that the TV supports the following formats for DLNA:
Video: MPEG_PS_NTSC, MPEG_PS_PAL, MPEG_TS_SD_EU, MPEG_TS_EU_ISO
Audio: AAC_ADTS_320, LPCM, MP3
Pictures: JPEG_LRG, JPEG_MED, JPEG_SM

Problem:
I tried to stream a .mkv file to the TV.
FFMPEG tells me about the file: Video: h264, Audio: DTS
When I stream the file, video is fine but there is no audio.

Here is what I tried to do:
First I created a Grundig_Interactive.xml with the following content and put in the resources/devicedb/Grundig folder.

The TV is detected like that even though there are now two entries in the device list but both with the same name.

The Questions:
1. In Twonky versions before 7 there seemed to be a ffmpeg.location file in cgi-bin to specify the ffmpeg location. Is this file still needed or where should I put the ffmpeg.exe?
2. In cgi-bin there is already a ffmpeg-m4v-mpeg.desc so I don't need to do there anything, right?
3. Is my .xml file correct? So twonky knows that it has to transcode my example movie when I start streaming it?


I really hope you can help me get this running and I am sure that this will help other people, too.

Many thanks,
Stip

Hi,

1. You can still add cgi-bin\ffmpeg.location containing the path to directory where the ffmpeg.exe binary is located, e.g. c:\Programs\ffmpeg\
2. Yes, all the *.desc files should still work, you may also improve it at you own risk
3. the XML below will transcode all MKV file to MPEG and give only that MPEG URL to the TV.
I am not sure about the HttpText, since I don't have the device. It should be part of the User-Agent of the GET requests from the TV, here: "AwoX/1.1 UPnP/1.0"

Best Regards,
Reinhard
