    Default Sony KDL Audio Sync 2.6.7

    Hi All

    I seem to be having audio sync issues with my Sony KDL-32EX600 TV with Mezzmo 2.6.7.

    The audio starts off fine and then the lip sync slips throughout. Stopping and restarting helps, but then the lip sync slips again.

    FFMPEG Properties as follows:

    The file has been pre-transcoded and the video appears perfect.

    Any suggestions?

    Thanks

    Hi

    As I mentioned in my e-mail reply:

    I tried the beta, with no luck, the audio lip sync still starts off OK and then gets worse as the movie progresses. Stopping and starting seems to re-synchronise the audio and video for a while.

    Also, after the upgrade to the Beta, the file which had been pre-transcoded was transcoded again. See image attached.

    Cheers

    Hi Mark,

    Thanks for letting us know about the duplicate pre-transcoded files issue. We replicated it and fixed it. It will be included in the upcoming Mezzmo v2.7 release.

    We also replicated the audio sync issue and we think we have fixed it. We're just testing it on several videos now. We'll be in touch when we're done.

    Hi Paul

    It seems that the re-Transcoding issue is fixed. Mezzmo did not try to re-trans code any files I tried after the upgrade.

    Sadly the Audio Sync issue is not fixed.

    Withing 10 to 15 minutes the Lip Sync is way off. A stop and start of the movie re-synchronizes the audio, but it soon drifts again.

    I know you guys reproduced the problem on your TV, but any other suggestions?

    This doe snot happen to all video though, but is very frustrating.

    Thanks
    Mark

    Hi Mark,

    Thanks for reporting this after upgrading to Mezzmo v2.7. We're looking into the audio sync issue now & hopefully can reproduce it again. If not, then we may ask you for a video file that does it for you. We'll be in touch after we complete our testing on this.

    Hi Mark,

    We did reproduce the issue again. Can you try this for us? Right-click on a video file (that is out of sync when playing on your Sony Bravia) in Mezzmo and click Pre-transcode Files. Select your TV from the device list and click Choose Formats. In the Transcoding Formats dialog, choose 'mpegts' and select the "Force full transcode" checkbox. Click OK and then select the "Pre-transcode files even if they match the device's supported formats' checkbox. Click OK and the video should begin transcoding. Go to the Transcoding pane to monitor progress and once transcoding has completed, try streaming the file to your TV. Let us know if that is better.
