    Default Repeating issue

    I am having a issue where when I am watching my video's on my Roku, during transcoding it is repeating 30 sec sections of the show that do not exist in the original format. This is getting really annoying, any ideas of what could be causing this. transcoding FPS is between 150 - 200 fps, and CPU is like 4% Memory is around 10% max.

    Thank you

    Hi,
    Mezzmo transcodes the file to 10 second segments for delivery to the Roku, possibly the Roku is requesting the same segments or Mezzmo is creating extra segments when transcoding. Can you please try playing a file that has already been transcoded or pre-transcoding a the file http://www.mezzmo.com/wiki/doku.php?id=pre-transcoding_files&s[]=pre&s[]=transcode to see if the repeating issue still occurs?

    Ok tested, Pre-transcoding works fine, however I did notice that when transcoding on the fly to a Roku device, it transcodes for a bit then says queue. Then when the 30 to 60 repeat happens, it starts transcoding again. It is as if it goes into Queue status, but forgets to transcode more, then the Roku goes HEY I need more, and it starts transcoding again but transcodes 30 to 60 seconds before it should. I had Mezzmo up while watching to see what it did, I found it strange that it Transcoded a lot, then just went to Queue but never transcoded again till the revert happened.

    What can happen when streaming hls is that the device will request a segment beyond what is currently being transcoded so Mezzmo will stop the current transcode and start transcoding from the offset requested. If the offset is not being correctly calculated by ffmpeg then it may start transcoding earlier than it is supposed to resulting in a repeat of a section of the video. Can you please try playing a video that had the repeat problem again to see if the problem still occurs after transcoding is completed? This will tell us whether the completed transcode has a duplicated section or if the device is requesting the same sections over again.

    Just watched another, it ran fine till it needed to transcode again, then it had the 60 sec repeat. It then transcoded more, and queues more, once it finishes transcoding it no longer reverses, however as long as it goes into queue and then starts transcoding again, that is where the repeat is every time. Once transcoding is 100% it never repeats again.

    I have turned on Logging now, unfortunately after I watched the last movie.. :/ But I will keep an eye on logs, and post them when it happens again.

    Also another thing I noticed, when watching the SAME movie, it will Transcode sometimes 10% before going into queue and sometimes even as far as 90% before going into queue mode. Its totally random on how much it Transcodes on the fly %

    We tried it here on a similar file and after transcoding was queued it resumed without the video repeating on the Roku. As a test can you please try going to Transcoding Settings in Mezzmo and disabling hardware encoding for transcoding to see if this is causing the issue?

    Still happening, I have watched 2 movies with it turned on, and both movies had a repeat. I will say its not as bad as it used to be, but it does still exist with the new ffmpeg. I have been able to cause it to repeat pretty easy as well, after you start watching the show, pause the show.. for a few min, then continue, it will happen within 30 min usually of doing that.

    Thanks for testing, we will make a change so that hardware accelerated decoding is not used for segmented files and this should workaround the issue.
