Hi,
I wanted to report my findings in this problem. I'm using ffplay compiled within the xbmc svn (no patches) so I guess I'm using the *same* ffmpeg that xbmc uses. I'm using ffplay as reference as I can not run xbmc in all my tests (when chrooted for instance, read below). My hardware is a mobo asus p5n7a-vm and e8400 at 3GHz (stock speed).
Hardy partition:
- Both xbmc and ffplay plays smooth killasample
Intrepid partition:
- Xbmc and stand alone ffplay drops frames
- running ffplay in the compile chroot (running it from intrepid) seems to *drop* frames
So, first of all we must take into account that I have no way (that I know of) to know the objective number of dropped frames in ffplay so it is more a subjective impression. To be exact, I can not use all hardy libs in the intrepid test, ffplay still links with intrepid libraries: libbz2.so.1.0 libpthread.so.0 libm.so.6 libdl.so.2 so it may well be one of them.
I'm going to try to reproduce the tests without gnome or any gnome deamons but I guess I need a way to know the dropped frames in standalone ffplay, anybody knows? How is xbmc doing it?
later and sorry for the long and not really so helping post :-(
EDIT: I have manage to run ffplay in intrepid using all hardy libraries but libc (obviously) and it *seems* to be better but as said I do need a way to report dropped frames in ffplay to be sure though!!!
