/* ChangeLog added 2002-01-10
|
|
* 2002-02-16:
|
|
* Fixed bug which would case invalid output when using :noprebuf
|
|
* Removed equalization code, it caused problems on slow systems
|
|
*
|
|
* 2002-02-13:
|
|
* Using the swscaler instead of the old hand coded shit. (Checkout man mplayer and search for sws ;).
|
|
* Using aspect function to setup a proper mpeg1, no more hassling with odd resolutions or GOP-sizes,
|
|
* this would only create jitter on some vids!
|
|
* The swscaler sometimes exits with sig8 on mpegs, I don't know why yet (just use -vc mpegpes in this
|
|
* case, and report to me if you have any avi's etc which does this...)
|
|
*
|
|
* 2002-02-09:
|
|
* Thanks to the new control() method I have finally been able to enable the em8300 prebuffering.
|
|
* This should speed up playback on all systems, the vout cpu usage should rocket since I will be hogging
|
|
* the pci bus. Not to worry though, since frames are prebuffered it should be able to take a few blows
|
|
* if you start doing other stuff simultaneously.
|
|
*
|
|
* 2002-02-03:
|
|
* Removal of libmp1e, libavcodec has finally become faster (and it's code is helluva lot cleaner)
|
|
*
|
|
* 2002-02-02:
|
|
* Cleaned out some old code which might have slowed down writes
|
|
*
|
|
* 2002-01-17:
|
|
* Testrelease of new sync engine (using previously undocumented feature of em8300).
|
|
*
|
|
* 2002-01-15:
|
|
* Preliminary subpic support with -vc mpegpes and dvd's
|
|
* Device interfaces tries the new naming scheme by default (even though most users probably still use the old one)
|
|
*
|
|
* 2002-01-10:
|
|
* I rehauled the entire codebase. I have now changed to
|
|
* Kernighan & Ritchie codingstyle, please mail me if you
|
|
* find any inconcistencies.
