transcoding ps3 firmware 2.35 mediatomb

[graveson]

does anyone have transcoding working flawlessly with the ps3 and mediatomb?

Bump....

Works very well here. Aside from not being able to seek during playback.

But not much that can be done about that, except converting everything to a supported format permanently.

Anyways here's my config.xml in case it helps anyone, this of course is specific to my needs and may not work so well for others.

This is set up to transcode all flash files and any avi files which are not compatible with the PS3, avi's which are compatible are ignored, also provides thumbnails for all videos and ignores any files which have an extension that isn't listed. I have no need for ogg or flac transcoding but also no reason to believe that just uncommenting the relevant entry and enabling the profile under it wouldn't work.

BTW after editing make sure this file is correct/valid, in my experience if it's not mediatomb will still run but will use up all available RAM and most available swap.

hey guys
everytime i try to transcode i get this message

this happens regardless of whether i use the code above or the one which originally came with mediatomb. I think the error seems to be here

I tried doing things like changing the permissions for vlc to 'read and write' but to no avail. Help!!

I can't even get my .ogg files to show up, much less try to transcode them. Anyone got any ideas about that?

[amak79]

Ardrias,

I suspect the reason why your Ogg files aren't showing up is that MT has assigned the wrong UPnP class to them. You can check the UPnP class via the MT interface. It should be set to "object.item.audioItem.musicTrack", but instead it's set to "object.item". This is a bug in MT that can be fixed by adding <map from="application/ogg" to="object.item.audioItem.musicTrack"/> to the <mimetype-upnpclass> section of config.xml.

However even if you did this you still would not be able to transcode them, as the current version of MT can't stream transcoded audio to the PS3. This has been fixed in the SVN version of MT.

[amak79]

csk,

The permission denied message means the user that is running MediaTomb doesn't not have sufficient permissions to access /tmp. MediaTomb must be able to write to /tmp for transcoding to work. You need to check the permissions of /tmp, it is usually world writeable.

[Ardrias]

Alright, I've just checked out and built the latest Mediatomb. I also did the mentioned fix for the PS3 to recognize OGG files. I had tried that before, but I think I might have forgot to rescan the directories.

Anyhow, I still cant figure out how to make it transcode OGG audio to the PS3. I've followed the Mediatomb wiki about transcoding, to transcode using VLC, but it just refuses to work.

What am I doing wrong?

[Keare]

Just wanted to thank Dies for his config.xml, I've been playing around with this for a few weeks with very little luck, but now it is working

Thanks!

[amak79]

Ardrias,

Do the Ogg files show up in your PS3 after you added the fix to the config? If you added the fix after you imported your Ogg files, then you will need to remove and re-import the Ogg files for the fix to take effect.

If you still can't get it to work, then please post your config.xml. Can you also post any useful info from the MT log file or messages printed to the console.
