Description

I have experienced this. specially mkv videos.

it's the "video queue len" that drops to 0, it doesn't increase from value 21 so this value seems to be too low. It doesn't do it all the time, but sometimes, specially in "high bitrate scenes", more movement etc.

For me this seems to be UPNP problem with HD movies, usb sticks work ok with all movies.

-From USB stick all videos work ok.
-From FUPPES upnp server SD videos work ok, but high bit rate videos stops when video queue len drops to 0 and picture stops". It freezes to couple seconds and then continues
-You can confirm this by pressing L3 and watch buffer dropping to 0 from 21.
-I have gigabit connection and same video if compatible works from ps3 internal player

i's funny that MPG TS streams video queue len is over 200 and it doesn't fall even down to 100.

suggested quick fix. Let user hard fix the vide queue len. to lets say 100-200

All showtime versions seems to have same problem, even latest unofficial

It's very annoying bug, please provide even "dirty fix":

I don't want to provide dirty fixes as it might screw up other things. Messing around with buffering setup usually have a lot of side effects.

I'm rather working on a decent fix but it will take at least 1-2 more days before I can commit anything.

It seems that mkv works now, I still got one buffer under run when watching 2 hours hd mkv movie.

Good job!

mpg files still have audio stuttering problem

I doub that 1 Mb for audio buffer is not enough if audio is uncompressed.

Could you do test build with 15 Mb video buffer and 2 Mb audio buffer.

I had problems with dreamtime.mpg (shuttle launch video) its 1280x720 mpeg2 HD video with very high bitrate

Could you send me ftp address where I could upload the video, could not find any place where it is still downloadable.
