    Default Jerky playback - Android App/Xbox 360

    Hi,
    The best way I can describe this is that it looks like the FPS are wrong, when I see any panning in the video, every few seconds it jerks (have had this before and it was when I accidentally ripped my files as 24 fps instead of 25

    This issue are far as I can see is affecting all my mp4 files when streamed to xbox using the android app (is it using the xbox video app for playback?), as all my files are ripped using the same settings

    If I play them using the xbox system player everything is fine
    If I play the files on my Samsung all is fine
    even playing the files on my PC all is fine

    but when sending from the Android app I get this jerkiness every few seconds on panning shots

    this is the details of one of the files

    I do see a message in the ffmpeg results about not enough frames to estimate rate and then mentions probesize (not sure if this is relevant)

    Thanks

    Mezzmo will be streaming this video directly to your Xbox 360 - either when you stream it via Mezzmo Android or directly using your Xbox 360's controller. From Mezzmo Android, it is telling your Xbox 360 that it should start playing the video that your selected in Mezzmo Android. After that, it is up to Xbox 360's firmware to play the file.

    Do you get a different result when you play it directly from your Xbox 360 (streaming from Mezzmo server) - i.e. does it play OK? If yes, then we'd like to see a set of logs when you are streaming it directly and a set of logs when you stream it via Mezzmo Android. Capture a set of logs in both cases and email them to us at support [at] conceiva [dot] com.

    Thanks, I will get some logs for you

    It is a different result if I stream directly

    Directly I am using the legacy video player (called system video player)
    When I stream from Androoid app it looks like it is opening the xbox video app for streaming (this one does not work directly on the xbox, only works for xbox purchased/rented videos)

    Just to clarify how I am doing it (going out this afternoon so will be tomorrow I can get logs, Tuesday for you)

    Direct on Xbox 360
    Press the xbox menu on centre of controller
    go across one tab and select the System Video Player
    this lists all local media and dlna sources
    select Mezzmo and find file to play
    ** Press A while playing and look at the playback controls/progress indicator at the top

    With Android app select the video and send it to the xbox
    ** Press A while playing as above, look at controls (this is using a different app for playback)

    It could be an issue with this app on the 360, but when playing the original way directly on the xbox the only one I have available is the first above, I don't know what app the Android app is getting the xbox to use (looks like xbox video app but that is a guess, if I open this app it only plays xbxox purchased/rented content, but looks like the one mezzmo is using)

    Log files have been sent

    1 minute playback via Android app which had jerky playback followed by 1 min playback direct on xbox which was perfect playback

    Hope the logs show a difference between the 2 playbacks

    Cheers
