samsung LA32D550 and transcoding

[waleed_hanafy]

hi mezzmo team from Egypt
first i would like to thank you for this great software and also great support i see in your forum
i have PC with core2quad processor and 2 GB ram
i have the latest version trial for mezzmo 2.7.1
i also have Samsung TV la32d550
the first question i have for you
-- my TV capable of playing rmvb natively i.e without transcoding(i know that from all share software and others dlna server like serviio) so i want to edit Samsung D profile to send rmvb files without transcoding them i .e what to wite in the profile
the second question is some time a skip to the next video happen it's random but always occur without any notification is there somethimg wrong with my setup note i edited the connection type to Ethernet cable (100 mb ) in the device settings
thanks in advance again

forget to mention that when i played this rmvb file it always skip to next track after 20-30 seconds


the information of the file as follows

so my point as my TV supports rmvb natively why should i trans-code it

[waleed_hanafy]

i added these lines to samsung D profile and then restarted the server


<avcontainer id="rm" name="rmvb" encode="0" mimetype="video/rmvb">
<video>
<format id="rv40" encode="0">
</format>
</video>
<audio>
<format id="cook" encode="0">
</format>
</audio>
<audio>
<format id="aac" encode="0">
</format>
</audio>
</avcontainer>

and TV gives me not supported format although all other dlna servers just send the rmvb file natively and didn't trans-code it

[Paul]

Please post the FFmpeg information on the RMVB file that is natively supported by your TV. To do this, right-click on the video in Mezzmo and click 'Get FFmpeg Information'. Once we get this,we will modify the Samsung D device profile for you.

this works well on my device so if you please i need two things
1-i want to watch rmvb natively on my tv
2-i want to transcode all non-native formats to the above mpeg-ps format that worked well after pretranscoding

[waleed_hanafy]

note2 when i used the SonyBraviaKDLW profile the file worked well but all my avi and mkvs transcoded

[Peter]

Hi,
we tried streaming rmvb files to our Samsung D here using Serviio and All Share and both reported that the file formats were not supported, so it is probable that these servers were transcoding the files to another format so that it plays on the device. You can try editing the Samsung D profile to change the preferred transcoding format from matroska to mpeg, look for the following line in the profile:

<avcontainer id="matroska" name="matroska,webm" encode="1" mimetype="video/x-mkv" dlnaprofile="MKV" preferredtranscoded="1" format="matroska" supportschunked="0" level="41">

Change preferredtranscoded="1" to preferredtranscoded="0" and then look for this line in the profile:

<avcontainer id="mpeg" name="mpeg" encode="1" mimetype="video/mpeg" baseline="1" dlnaprofile="MPEG_PS_PAL,MPEG_PS_NTSC" format="vob" supportschunked="0">

Add preferredtranscoded="1" to the attributes so that it becomes:

<avcontainer id="mpeg" name="mpeg" encode="1" mimetype="video/mpeg" baseline="1" dlnaprofile="MPEG_PS_PAL,MPEG_PS_NTSC" preferredtranscoded="1" format="vob" supportschunked="0">

and then save the file and restart your Mezzmo server, your rmvb files will be transcoded to mpeg when played on the fly.

[waleed_hanafy]

didn't work gave me unsupported format
regarding rmvb i used all share and ps3 server and all play rmvb files without transcoding because in ps3 server settings i put rmvb in formats not to transcode i tried serviio before but it didn't support rmvb at all i will try it now and inform you
thanks for your patience
note when i used the SonyBraviaKDLW profile the same file will play strange isn't it?

[waleed_hanafy]

the file now works natively i added these files to samsung D profile

<avcontainer id="rm" name="rmvb" encode="0" mimetype="application/vnd.rn-realmedia-vbr" supportschunked="0">
<video>
<format id="RV40" encode="0">
</format>
</video>
<audio>
<format id="cook" encode="0">
</format>
</audio>
</avcontainer>

thanks for this great software also i can seek in and out in rmvb

[Peter]

Glad to hear you have got this working, our Samsung D here does not support rmvb so even after making this change in the device profile we get not supported format when trying to play the files. We will not include this change to the device profile in the next version of Mezzmo, so please make sure to backup your modified device profile before updating Mezzmo.
