Audio Sync issue with MP4s using PS3

[procon]

Hello,

I have purchased Mezzmo quite some time ago and it seems as if I have a weird audio sync issue. Ill play the movie then over time the movie will become out of sync. I can play it on any other device w/o mezzmo and its fine. I was reading on the forum that you guys emailed someone a modified ps3 file? Do i need that? All my movies are mp4s which the PS3 doesn't need to transcode.

Here is the FFmpeg info;

Given that Mezzmo is streaming your MP4 file directly to your PS3, then any audio sync issues will most likely be caused by your PS3's firmware not being able to keep the video and audio in sync with that particular MP4 encoding. Mezzmo is simply delivering the MP4 file to your PS3 without any modification. As a test, right-click on one of the MP4 files and click 'Pre-transcode Files'. On the Pre-transcode Files dialog, select your PS3 and click 'Choose Formats'. On the Pre-transcode Formats dialog, select the bolded format and select the 'Force full transcode of all channels' checkbox. Click OK and the select the 'Pre-transcode file even if they match the device supported formats' checkbox. Click OK to start transcoding. Wait until it has completed and then try to stream the MP4 file using Mezzmo. If there are no sync issues, then it does look like your MP4 files' encoding may not be being handled well by your PS3's firmware.
