Freezing mid-presentation/End Of Stream error

We have a set of 10 monitors with 1 master.  The presentations have about 15 states and the master sends out sync commands on each change of state.  Twice now, when we have uploaded new presentation via the BSN, the presentation will simply hang in the middle of playing during the first time through.  The programming seems fine and worked when we were just on local networking.  I was able to fix it the first time by deleting all the media and the presentation off the BSN and re-uploading. 

Now that this is the second time it has happened, I am looking a little deeper.  This is what I saw on the master log when it hung.  It is similar to what I saw the first time it happened, though it is a slightly different presentation and it is freezing in a different point.

    What are the models of the brightsign units, what firmware versions are they running, what BA version did you use to create the presentations?

    Is it only 1 particular device that hangs in the middle of the presentation? Does it always hang at the same place during playback? Or do the multiple devices experience this issue?

    Please attach the master project and one of the slave projects to this post. Send just the *.bpf files.

    Device doesn't care which method do you use to publish a presentation to the SD card. It's unlikely that the BSN is a problem here.

    This FAQ has valuable tips about synchronization to look at:

    http://support.brightsign.biz/entries/21146497-what-factors-can-affect-the-synchronization

    It will be also helpful, if you can send us the full specs of the video files that are involved in the presentation that is playing on the brightsign device that is having playback issues. You can use the mediainfo program to get the full specs of the video files: http://mediainfo.sourceforge.net

    Did you test the unit(s) with different SD card(s)?

    Model: HD1020

    Firmware: 4.4.44

    BA: 3.5.0.24

    It was the master that hung, so the rest were frozen waiting for the next sync command.  Always at the same point.

    >Device doesn't care which method do you use to publish a presentation to the SD card. It's unlikely that the BSN is a >problem here.

    I was more concerned about the multiple file transfers giving more opportunity for file corruption.

    No, though the thought crossed my mind.

     

    An update...  When the presentation hung yesterday, it was on a slide with Live Text with a BSN  RSS feed.  I changed the Live Text type from RSS Feed to Live Text Data and it started playing through again.  However, the first time it hung was just on a still image.

    Do the same presentations work fine on the same units with the same SD cards when publishing locally? I don't see Live Text widgets in your projects. What is the name of the image in the master presentation the master unit hangs on? Does the problem persist after you reboot the master unit? You can send a login to your account to support@brightsign.biz so we can set the units up to connect to your account and see if we can duplicate the problem.
