Thread: Panasonic Viera and MP4

    Default Panasonic Viera and MP4

    I have a Panasonic Viera TV, model TX-P50V20B which I purchased in 2010. I've experimented with the 2009 profile and also the 2011 profile.
    Using the 2009 profile the TV struggles to stream most formats. With the 2011 profile it seems to play most formats ok, but struggles with high-def MP4's (BluRay rips, 1080p supposedly) - the picture stutters and is very glitchy.

    suspecting it may be a wireless bandwidth issue I connected the TV with a wired gigabit connection - still same issue. I've then experimented with changing the Video Bitrate settings in the Performance Tab, again struggling.

    In order to try and get the MP4 files to play I've turned on transcoding -
    on the fly transcoding doesn't work well - I'm using an HP Microserver to store the media and the processors are 100% CPU during the process
    pre transcoding works, but the quality isn't the best - it's actually very poor

    Nothing is wrong with the files I'm trying to stream, as it plays perfectly well on a Sony Bravia TV I purchased in 2012.

    Can anyone suggest anything else I can try before I spend 60 on a WD TV ?

    My guess is that your TV is struggling decode and play your MP4 files due to their high video bitrate. Pre-transcoding the video to another format with the Video bitrate slider reduced to (say) halfway should get the videos playing - and with little or no loss of quality. Try moving the Video bitrate slider to different positions and pre-transcoding again to see the effect on quality.

    If still no success, then post the FFmpeg information for the video. To get this info, right-click on the video and click 'Get FFmpeg Information'. Also, right-click the video and click 'Properties', On the Properties dialog, go to the Transcoding tab. You should see the transcoded file listed there for your TV. Select it and click 'Get FFmpeg Information'. Post that information here also.
