Lag in video files when forward and rewind the movie

[ggdiez]

Hi Kostantin

Thank you very much for this amazing project.

Every file that I play in project works fine. But I have a problem when I move the uislider left or right. In this cases I see in the console these messages:

[ac3 @ 0x1fa9d000] frame sync error
decode audio error, skip packet

or in other case this messages:

desync audio (lags) skip 1415.2881 1413.0240
desync audio (lags) skip 1415.2881 1413.0560

How I can solve this problem?, if it is possible. ;)

Pd. I forgot that I use for testing iPad 3 and iPhone 5

Thank you,

Hi,

These messages are just for diagnostic and debugging and you can ignore them.

Best wishes.

Thanks for your answer.

But the problem is not only this messages in console, in some of this cases the image and the voice doesn't work in the same time.

Hi,

IMHO, it's normal behaviour for some video\audio formats.
But you may hack [KxMovieDecoder setPosition] method.
Look at avformat_seek_file method and try to tweak min_ts / max_ts arguments.

Best wishes.

Thank you for your answer.

I will try to tweak this arguments in this cases.

Best.
