Problems transcoding on Technicorder

Hi

I have a problem while transcoding a mkv-file on the Technicorder (Technisat) to change the audio codec DTS to AC3. The file is not playble, doesn't start.
This is the profile definition:
<Profile id="technicorder" name="Technicorder ISIO STC" extendsProfileId="1">
<!-- Technicorder -->
<Detection>
<UPnPSearch>
<FriendlyName>TechniCorder ISIO STC</FriendlyName>
<Manufacturer>TechniSat</Manufacturer>
</UPnPSearch>
</Detection>

<Transcoding>
<Video targetContainer="mpegts" targetACodec="ac3" aBitrate="384" forceInheritance="true">
<Matches container="matroska" aCodec="dca"/>
</Video>
</Transcoding>

</Profile>


I've no idea what I'm doing wrong.

Thanks for help

Just a guess, since I have no idea what Technicorder supports. Your profile is only transcoding audio, so whatever video codec is on your MKV container is being passed through. If the video is unsupported, you would likely get a playback error, as it sounds like is happening.

You might try changing your transcoding line to "<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="384" forceInheritance="true">", and if that doesn't work you could try "<Video targetContainer="mpegts" targetVCodec="h264" targetACodec="ac3" aBitrate="384" forceInheritance="true">"

But I'm just making a guess on what codec might work.

Hi Dan

If I don't do any transcoding, the video ist watchable, but without any audio because of DTS that is not supported inTechnicorder.

Well, I'm at a loss then. I don't know if you need the forceInheritance switch. Other than that, I don't know why it's not working. All your XML tags are correct, and I see nothing amiss. Maybe try removing the audio bitrate as well. Who knows? I use an audio bitrate of 512, but maybe your device can only handle certain bitrates.

I think nothing helps.
My last try:
<Video targetContainer="m2ts" targetACodec="ac3">
<Matches container="matroska" aCodec="dca"/>
</Video>

I give up

That isn't a valid container. "name of container to transcode into; possible values: asf, mpeg (MPEG2PS), mpegts (MPEG2TS), applehttp (HLS)"

I got this error message, after intentionally gave a wrong container:
Value 'm2pegts' is not facet-valid with respect to enumeration '[asf, mpegvideo, mpeg, mpegts, m2ts, flv, applehttp]'. It must be a value from the enumeration.

But also all the other choices didn't run.
Thanks for your help

Did you ever try "<Video targetContainer="mpegts" targetVCodec="mpeg2video" targetACodec="ac3" aBitrate="384" forceInheritance="true">"? While it transcodes the video, probably without need, it least we could see if it works.

It's also possible that the Technicolor device just doesn't like transcoded files. There are some Samsung TVs that are the same way. If it's native it works fine, but transcoded files failed, even with perfectly acceptable transcoding configuration.
