I can stream TV series and films of any type with no problem at all. However if I pause any stream at all upon restarting it after a minute or so I always get the message "Video Data Not Supported". I stop the stream and restart it and all is ok. So really Im wondering why it has this strange characteristic.

Not sure why you are getting this problem. It could be a firmware issue within the device. We'll need to know your device (including model number), the device profile assigned to your device (see Media Devices dialog) and the FFmpeg information for one of the files that have this problem (right-click on the file in Mezzmo and click 'Get FFmpeg Information').

Paul. The TV is a Samsung UA48H6400. The profile assigned is Samsung H. TV is directly connected using a lan cable so no wireless problems. Have attached the FFMPEG info from the most recent film to do it today.

Thanks for the information. Mezzmo server is streaming this file directly to your TV without any transcoding or modification. So it's strange your TV produces the error message. It's best we see a set of logs when this error occurs on your TV. Turn on logging in Mezzmo (see http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) and restart your Mezzmo server. Now reproduce the "Video Data Not Supported" error. When it occurs, stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com.

Also, as a test, try reproducing the problem when a video that is not .MP4 and see if it occurs. Let us know what you find.

Have logged the error happening and emailed it to you. I will try with an avi and mkv when I get a chance and let you know what happens. Although Im pretty sure it makes no odds as it does it with every file.

OK - thanks. We'll analyse the logs and report back via email.

For some reason when I attach the zip file to an email it will not deliver to you. I just always get back a message saying the mail could not be delivered. I have uploaded it my google drive instead for you. https://drive.google.com/file/d/0B-Ajh4D9q_Q1UnNMc3Exa2JIUjQ/view?usp=sharing

If the email attachment is > 10MB, then it will be rejected. Perhaps that's the reason.

We'll download the logs and analyse them shortly. We'll report back here.

Update: We've had reports from several Gmail email users that their emails with attachments to us are not getting through to us. Looking at the Gmail support forums, it seems Gmail is having problems with ZIP attachments as many people are complaining about the same problem. Google is apparently looking into it. So for the moment, upload your attachments to a filesharing site like OneDrive, Google Drive, Dropbox, mega.co.nz, etc. and email us the download link.

Hi Marshall1975,

Please email us at support [at] conceiva [dot] com and we'll provide a tweaked device profile to try.

Thanks for the new profile. The problem still persists though. I tried your earlier suggestion about using an MKV or AVI and the problem does not happen. It only happens with MP4 files. I have done another set of logs with a different MP4 for you to have a look at. https://drive.google.com/file/d/0B-Ajh4D9q_Q1Uy1FVmlrRlVLQkE/view?usp=sharing

Thanks for the further information. The fact that it only occurs with your MP4 files is a good clue. It could be either a deficiency in your Samsung H-series TV's firmware (i.e. it cannot resume MP4 - h.264/AAC files), or it could be the MP4s that you have are encoded in such a way that your Samsung H-series TV cannot resume playing the file from midway within the MP4 file. We'll email you a new device profile & steps to try.

When I select choose formats on the pre transcoding menu the only options I get to select are : ASF, MATROSKA, MPEG and nothing else. If I select MPEG the next box has one option only which is MPEG2VIDEO (30FPS).

Regards

That's strange. The new device profile that I provided should also allow MP4 pre-transcoding. Did you copy the .PRF I sent you into the DeviceProfiles folder? And did you rename the old SamsungH.prf to something with a different extension (e.g. SamsungH.bak). If you don't, then the old .PRF will still be picked up by Mezzmo and may conflict with the new one I provided. If still no success, then email us a set of logs and we'll know what device profile you have.

Paul have attached another set of logs for you. I find it strange that any MP4 is doing this. I have multiple MP4's from multiple different sources so surely they all cant be encoding them in a weird way that causes this issue. Anyway these logs are from a different MP4 so see what you think. https://drive.google.com/file/d/0B-Ajh4D9q_Q1LXRpOWQ2ZEh0M2s/view?usp=sharing

Thanks for the logs. Stop your Mezzmo server and exit Mezzmo. Now rename 'Samsung.bak.prf' to 'Samsung.bak' in the DeviceProfiles folder. Tthe problem is that Mezzmo loads all .prf files form this folder, so it is still picking up your old Samsung H-series device profile and this is conflicting with the new one I sent you to try. Next, run Mezzmo and pre-transcode the MP4 to MP4 as I explained in my email to you. Once fully transcoded, then try streaming it and see if the problem occurs with the newly transcoded file. Let us know the results.

Marshall1975

Paul. Did as you asked and was able to transcode a file as requested. Although the transcoded file still does the same if its paused. Have attached the latest set of logs for you to look at. https://drive.google.com/file/d/0B-Ajh4D9q_Q1LXRpOWQ2ZEh0M2s/view?usp=sharing

OK - there's nothing wrong in the logs. Mezzmo server is delivering whatever your TV requests. It really does seem to be a TV firmware issue whereby your TV just cannot resume playing MP4 video files. Sorry, there's not much else we can do about this :(.

OK paul no problem. Thanks for the effort in trying to sort it out. Im sure I can live with it.

Paul I know the thread is old but i was playing some mp4 files from a usb stick the other day and I paused a few mp4 films and once un paused they continued to play perfectly fine. Would this not indicate that the firmware of the tv is quite happy with pausing. They only shut off after pausing if played through mezzmo.

Hi,
playing files from a USB stick and playing them from a media server can be quite different functions for a TV and may not use the same part of the firmware. When a file is played from USB the device has access to the full file and can seek around to find the part it wants but when streaming from a media server the device must request an offset in the file from the media server and depending upon how the firmware operates this may behave differently when the media server returns the file data.
