audio out of sync when transcoding..

[thenamelessthing]

Hi all, when transcoding is used. The audio became out of sync after few second. The profile used is the Panasonic Viera E/S/ST/VT (2011).

Here is the command used by ffmpeg:

2013-01-10 22:20:04,413 DEBUG [ProcessExecutor] Starting ffmpeg -threads auto -i /data/Teleseries/Jekyll.S01.FRENCH.PDTV.XViD-NYJ/Jekyll.S01E05.FRENCH.PDTV.XViD-NYJ/Jekyll.S01E05.FRENCH.PDTV.XViD-NYJ.avi -y -copyts -c:v mpeg2video -qscale:v 3 -r 25 -g 15 -c:a ac3 -b:a 128k -ac 2 -map 0:0 -map 0:1 -sn -f mpegts /tmp/Serviio/transcoding-temp-6434-viera2011-ORIGINAL.stf


I also try with Best video quality and downmix to stereo without any success. I also select to use 4 core on the 6 my cpu have. And I have 2.4gb of free ram when transcoding and enough space disk.


Here is the info if the file played:

Thanks for your help!

[zip]

It you run the ffmpeg command and rename the .stf file to .g, add it to your library, does it play correctly?

[thenamelessthing]

Sorry for this "noob" question, but how I add it to the library? And what happen by only renaming .stf file to .g ? ( i want understand how serviio works in the background)

[zip]

sorry, was a typo.. rename it to .mpg and copy to a shared folder, then play (without transcoding)

[thenamelessthing]

I have do what you have asked. When I play the mpg on my computer it work fine. On tv I always have the audio sync problem. ;-(

EDIT: even .mkv have the audio sync problem!!!!!!!!!

[thenamelessthing]

So, I think with this info maybe it's not a transcoding problem...

[thenamelessthing]

Maybe the router is my problem? ( linksys wrt54gl ) But the load seem to be okay..

[zip]

so the .mpg file, when played on TV has the problem, right?

Try this:

  Code:

ffmpeg -threads auto -i "/data/Teleseries/Jekyll.S01.FRENCH.PDTV.XViD-NYJ/Jekyll.S01E05.FRENCH.PDTV.XViD-NYJ/Jekyll.S01E05.FRENCH.PDTV.XViD-NYJ.avi" -y -copyts -async 1 -c:v mpeg2video -qscale:v 3 -r 25 -g 15 -c:a ac3 -b:a 128k -ac 2 -map 0:0 -map 0:1 -sn -f mpegts /tmp/Serviio/test.mpg

Then try to play test.mpg on your TV.

[thenamelessthing]

Yes the fila has the problem on tv.

Ok I will do it this evening...

Thanks you for your help.

[thenamelessthing]

I have do the test you suggest. The problem is still here! I also tried to put the file on an usb stick and play it directly on the tv. Same problem occur. With these test at least I can say it's not a network problem!

[zip]

does it play out-of-sync in VLC?

[thenamelessthing]

I have checked this yesterday with mplayer (ubuntu) and the audio was ok. I can check this evening in vlc if it's really important.

[zip]

do ll your files have this problem? It looks like a problem of the TV. Do you have the latest firmware?

[thenamelessthing]

I will check this evening if a new firmware is available I will try to contact Panasonic too . I have updated the firmware in november. It's not ALL files who have the problem but most of all. If I remember correctly (i'm not at home) I have mkv files in 720p who work fine. The problem seem to affect some avi file (HD or not) who are transcoded and some mkv (1080p) who are not transcoded.


To be continued

[thenamelessthing]

Shit happen! It really look a tv problem!

I have some file who play correctly like:

I have contacted Panasonic, the first thing they suggest is the Factory reset the TV. Done without any good result.
I can confirm i'm at the latest firmware version.

Any other advices? (transcoding into a file format who play fine like file at the top of this post??)

[zip]

Did you try disabling transcoding?

[thenamelessthing]

I will try this this evening.. (disabling transcoding)

I have obtained the supported file format supported by the tv:

Media Player Supported Formats AVCHD 3D / Progressive, SD-VIDEO / MotionJPEG (Lumix) / MKV / MP4 / MOV / M4v / FLV / 3GPP / VRO / VOB / TS / PS, MP3 / AAC / FLAC, JPEG / MPO


Do you know if AC3 and AAC is the same thing?

[zip]

they are not

[thenamelessthing]

With transcoding disable same problem. I have open a ticket on panasonic. 2-4 working day before having news from technical support (level 2). I think it's a bug in her firmware. on my 2 tv I have the same problem and they are from the same series... I will poste the panasonic answer/solution when I obtain it.


Thanks you zip for helping me to debug this weird case!

[thenamelessthing]

Hi, I think I have found something!

I have used handbreak to convert one of my file we have use on our test (. And I have re-encoded the audio in the same format but with a little change. The original audio used was AAC (faac) and I changed it for: AAC (ffmpeg) and the mpeg to mkv and the audio are now sync!! maybe this info can us to solve the problem?

Here is the result of the file who play fine now...
