Proposed ebuild for mediatomb - uPNP media server

Crapo,

If you want the MediaTomb logs to be more verbose then emerge MediaTomb with the debug USE flag enabled. Cidero is a great tool for analyzing the XML sent by MediaTomb and I have been using it for a while. The <first-resource> tag should already be in the transcoding profiles posted on the Wiki. The <hide-original-resource> tag is usually not necessary as most UPnP devices simply play the first resource which in this case is the transcoded stream. However for testing it might be needed to ensure that the UPnP device is not selecting the wrong resource. It is normal for UPnP servers to send multiple resources as it's part of the UPnP specification.

If you take a look at the XML from the ASX resource you should see the URL that MediaTomb is sending to your UPnP device. Try playing that URL with VLC or MPlayer and if it works then it's an issue with your UPnP device. Your device might have a similar issue to the PS3 with streams that have an unknown content length. This is the issue that you noticed about missing fields but it's impossible to add a size or length field for an Internet radio stream. The MediaTomb developers were testing a hack that faked the content length with a very large number but it's still very experimental. If you still can't get it to work I suggest you log onto the MediaTomb IRC and speak to the MediaTomb developers. They will probably already know if it's possible to play transcoded internet radio streams with your UPnP device.

I would like to say a TIP, disable the WEBUI, it shows all the / fs. I have jailed and works fine, but it is not the default.

can any PS3 user post a fully working config file?

im getting unsupported file messages and have been trawling the web looking for answers and cant find any. a working config file would be grea to let me check though mine to see if im going wrong there or not.

NoNaMeNo,

You are correct that the MediaTomb WebUI exposes the entire filesystem, but most people will be using MediaTomb in a home LAN which is a trusted environment so security is not a real concern. MediaTomb does offer a simple account mechanism (disabled in config.xml) but it will not stop serious security threats. I will probably add a notice to the Wiki just to remind people of the possible security issues.

c8a7w,

I have sent you my working config.xml. Please report your results.

c8a7w,

Good to know you have it working.

I have added a section to the Wiki for PS3 video thumbnail support. The thumbnails are generated by FFmpeg Thumbnailer which is in Portage. I recommend using the latest version (1.1.5) which is keyword masked. Enjoy

ooooo i will try that later!

anyone know if there is a way to only transcode the files the ps3 doesn't support? or would i have to transcode EVERY .avi file

c8a7w,

MediaTomb can selectively transcode AVI files based on their FourCC. The MediaTomb developers have also looked at transcoding AVI files based on their QPEL, but there doesn't seem to be any quick and easy way to identify the QPEL.

When ffmpeg transcodes some matroska files, I get "corrupted data" messages, however if I retry playing the file 4-5 times it will suddenly start playing. The result is a video that freezes a lot, sort of like my server was too slow to play it properly. As far as I can tell, the matroska files in question are 100% similar (same codecs) to other files that play just fine on my PS3.

BT, have you run across this? any ideas?

EDIT: Solved, sort of. I changed my buffer sizes to <buffer size="10485760" chunk-size="262144" fill-size="524288"/>. I also updated to the latest svn revision 1707. Now the files play without corrupt data messages, but playback is still jerky. Almost forgot, concerning video metadata I changed from using ffmpeg to libextractor.

Can someone send me a working config file that will transcode AVI videos? Here's my config that works for H264/M4V videos. MP4/AVI doesn't work.

Thanks!

Heion,

The jerky video playback can be caused if your machine is too slow. This usually happens with HD video where the resolution is very large. You can try increasing the transcoding buffer sizes. The default buffer sizes on the Wiki are 10MB, 256KB, 512KB. Try setting the buffer size to 20MB and fill size to 1MB. The larger buffer sizes will result in longer playback time. Using libextractor will not cause jerky video playback but import speed will be affected as libextractor is very slow at extracting metadata. Also, the MT developers have finished work on the latest version and plan to release sometime this week.

instigatorx,

Remove the <avi-fourcc-list mode="ignore"> </avi-fourcc-list> section from the vlcmpeg profile. You could also just set mode="ignore" to mode="disabled".

sensee,

I have sent you my config.xml. Please report your results.

sensee · Posted: Fri Feb 29, 2008 8:10 am Post subject:

Yeah, i saw the config but have not tried it yet, will do in this weekend when i get home from work.

As of now i have a "quite large" list of unplayables and i thought i should try and narrow the list down asap so we could get on with "solving the unplayables"...

I will return with my "list" when i have tried your config as well as my own (i created one while emerging... ;O ).

sensee,

When you post your list of unplayable media could you also specify which UPnP device you are using. I'm not sure how much my config.xml can help you as I have only added PS3 DivX support and transcoding profiles for FLAC and Flash files. The rest of my config.xml is identical to the one posted on the Wiki.

Oh, i also forgot to mention that i am really grateful for all the solid and good work all of you have put into this "project" so far.

I hope to be able to contribute some as well.

MediaTomb 0.11.0 has been released!. The main feature of this release is obviously transcoding. The full change log can be found here. It looks like the MediaTomb developers removed the YouTube feature just before release. I don't know their reason for doing so as I wasn't around when they released. I strongly suggest you completely remove any previous versions before installing 0.11.0, just make sure you backup your config.xml. To remove previous versions:

Hooray! Mediatomb 0.11.0 works like a charm. Thanks for your good work, everyone.
