Thread: Unable to play mkv on Sony BDP S390 Without Transcoding

    Default Unable to play mkv on Sony BDP S390 Without Transcoding

    I recently installed Mezzmo and I'm in the process of evaluating the software for purchase. I have a Sony BDP S390 and am unable to play .mkv files without transcoding. I verified the S390 will play mkv files running Serviio with a generic profile and transcoding disabled. In Mezzmo, I tried all the Sony BDP profile options and none would allow streaming mkv files. Some of the profiles allowed the S390 to see the mkv files but when I tried playing them the S390 said the files were corrupt. Since the S390 is perfectly capable of playing the files direct, it's a complete wast of disk space and CPU cycles to transcode the files while playing them.

    Is there any way of playing the mkv files without transcoding? I saw a similar post on this exact issue from Jan 2012 but the post was for a different Sony BDP and a final answer was never given.

    Please post the FFmpeg information on the MKV file. To do this, right-click on the file in Mezzmo and click 'Get FFmpeg Information'. Once we get this, we can tell you the most appropriate device profile.

    One workaround for the moment is to turn off transcoding so that your MKVs will be streamed natively to your Sony BDP. To try this, go to the Media Devices dialog in Mezzmo and edit your Sony BDP device. Go to the Transcoding tab and turn off the transcoding checkbox. Now all your files will be streamed without any transcoding to your Sony BDP.

    Default FFMPEG Data

    As stated in my previous post above, if I disable transcoding in Mezzmo, the BDP S390 is unable to play the mkv file. The same mkv files play just fine with no transcoding in a competing DLNA server: Serviio. If I disable transcoding in Serviio, the exact same mkv files play just fine. Here is the ffmpeg data you requested:

    Thanks for the additional information. Try this: Please stop your Mezzmo server. Go to the Media Devices dialog and delete all your devices. Start your Mezzmo server again. Your Sony BDP should be re-listed in the Media Devices dialog. Set the device profile for it to "Sony BDP (PAL/NTSC, MKV, No DivX)" and try streaming the MKV file.

    If it transcodes (go to the Transcoding pane to see this), then stop your Mezzmo server. Please turn on logging (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Try streaming the file again, and once it begins transcoding again, stop your Mezzmo server and exit Mezzmo. Zip up the logs and send them to us at support [at] conceiva [dot] com.

    I sent an email with the requested information above but never received a reply from your tech support department. It turns out I misspoke above. I am unable to play any .mkv file on the Sony BDP-S390 with transcoding enabled or with transcoding disabled. I get an error message from the S390 that says the file is corrupt. Mezzmo simply does not play mkv files to the S390 correctly. I can play the same files with Serviio with no problem.

    Sorry for not getting back to you earlier. Looking at your logs, Mezzmo is delivering the MKV file to your S390, but your S390 rejects it immediately. This may suggest that your S390 cannot play MKV files. As a test, please change the device profile to 'Sony BDP (NTSC, No DivX)'. This will transcode your MKV files to MPEG-TS. Try streaming a MKV file now. When streaming the MKV file, go back to Mezzmo and check the Transcoding pane to see the transcoding status of the MKV. If the MKV failed to play on your S390, then wait until the transcoding has completed and then try to stream the file again. This time Mezzmo will stream the completed transcoded file.

    If no success, then please send us a new set of logs so we can see what your S390 is requesting from Mezzmo server.

    It turns out Twonky also successfully plays mkv files to the BDP-S390.

    Greetings Paul:
    I'm not sure why you don't believe me but the Sony S390 is capable of playing an mkv file with h264 video encoding. The specifications for this device clearly state that it is capable of playing video in this format - you can look it up on the Sony web site if you don't believe me. Furthermore, I successfully played the same media file using 2 different media servers: Twonky and Serviio. Note that the default install of Twonky is not capable of transcoding so it has to be streaming the file natively. In testing Serviio, I specifically disabled all transcoding before streaming the file. Your post above suggests that you believe the problem is caused by the fact that the S390 can't play mkv files and there is no problem with Mezzmo. I disagree because the data that I collected proves otherwise.

    If I select the 'Sony BDP (NTSC)' device profile and enable transcoding, the file does play but it appears that the file is being transcoded. I checked the transcoding output directory and found a large video file there; I opened the video file with VLC media player and it was the same file I was trying to stream. This test shows that Mezzmo can play the file but it has to transcode the file to successfully stream without errors. If I disable transcoding, the file will not stream successfully.

    I would like to re-post my original question. Why can't Mezzmo stream an mkv file with h264 encoding to the S390 without transcoding? It's a complete waste of disk space and CPU cycles to transcode files that don't need transcoding.

    I am currently evaluating DLNA software for purchase. Mezzmo does everything I want except it won't stream mkv files with h264 encoding without transcoding. Perhaps it's a simple case that the Mezzmo software doesn't know that the S390 is capable of accepting h264 encoded mkv files. If I disable transcoding, the Mezzmo software does not present any playable files to the S390. When I navigate to a directory which contains mkv files, Mezzmo report that there are no playable files. I think if mezzmo just reported all the mkv files as playable (like it does for mpg files), it would work fine. Is there a way to modify the Sony Bluray profile so that Mezzmo will stop transcoding the mkv files? If there is a fix for this problem, I will purchase the software. I wouldn't have spent so much time looking into this issue if I didn't like your software. Please help me fix this problem so I can purchase your software.
