MP4 Sound /video sync issues on Bravia running Serviio 0.5.2

Hi all,

First off, I want to say I've been really happy with Serviio; it plays almost all of my library fantastically. However, for certain video's that I've encoded using Handbrake, the video starts off running at 1.5 times normal speed (est.) and the sound is about 2 seconds behind.

I thought it might be issue #201, but since it was fixed in version .5, I'm not so sure. It only appears to happen on files haveing been encoded using the HandBrake iphone preset profile. Using the normal profile doesn't appear to show this problem.

Anyway here's the pertinant information (let me know if you need more):

I'm running Centos 5.6 using the ffmpeg provided by rpmforge. The TV is a Bravia KDL46NX810.

output from process listing ( at start ):

  Code:

I went through all the previous posts for the past 2 months, I wasn't able to find this issue. I was curious if this has come up before. Thanks for any and all help y'all can provide.

[Illico]

The audio source is low "127 kb/s", could you try to modify the output audio bitrate option with aBitrate="192" under Sony Bravia profile (replace the "384" )

Thanks for the response!

I updated the profile in config/profiles.cml for Bravia and change all audio bitrates to 192. Stopped serviio, killed the java process, restarted, tried a different video in the same series in case there was caching. Unfortunately, I got the same result as before.

The video and the audio could actually be of sync in media_file.mp4

I had a video/audio sync issues and had this message from ffmpeg
"seems stream 0 codec frame rate differs from container frame rate".

Playing the video using VLC was ok, I read a thread where VLC sometimes can automatically sync video/audio using PTS. They said to try a different fps close to the original.
Manually picking a fps fixed my problem.

OK, I'll give that a shot. Thanks! It looks like it's not just that profile that's having the problem, all mp4s are. I'll fiddle with the settings some and see if I can get success. I'll post here if I find anything else out.
