Hello vlc,

  I want to remind windows port maintainer about following bugs
  submitted long time ago:


  These are about implementing standard windows hotkeys.
  They might be closed or appended with
  I think vlc-0.6.0 _MUST_ have windows-like behaviour so everybody
  could enjoy VERY stable player. It should be possible to make keys
  skin-specific. Please get the Media Player Classic and check their
  awesome "Keys" menu.

  There's also interface-related thingie
  which wasn't implemented yet (or will never be implemented) but it
  reminds about missing audio controls in current win32 version.

  wxWindows context menu opened by rightclick on win32 should be
  closed by single click on video output, not only on interface.

  It is not possible to close video window when context menu is
  I also think that player should not be closed when video is closed.
  I have to open player each time to open new video and I don't want
  to go to interface (e.g. it's overlapped by the interface and i'm
  too lazy to use taskbar), push stop and then open new video.

  If you drag'n'drop file into playlist it will be immediately played.
  There was
  issue 3) and it was fixed but seems that nobody was trying to

  I was also thinking about window names. Interface is VLC but the
  name was changed to "VLC Media Player"? Second one (video) is
  VLC (-ware direct/whatever output). Third one is just "Playlist".
  Did you get the point?

  And BTW. Every time new video is being played you are closing old
  surface (or whatever) and opening new one... Is this good or bad
  thing :) ?
  This one should be closed:

  It works here under XP (yuck), but 2 other problems arise:
  1) Default behaviour should be "add to playlist". After second
  doubleclick on associated file second instance of vlc is opened
  right now. 

  That problem was found cause of previous problem:
  I'm testing 0.6.0-test1 and if I open 2 vlcs at the same time and
  try to play two videos at the same time they are trying to use same
  overlay as far as I understand thus only first vlc is showing
  something, second one is playing music. When first one ends, second
  one (and the only one left) starts to show video after some time.

  Today I've also seen this kind of crash:

AppName: vlc.exe         AppVer:         ModName: liblibmpeg2_plugin.dll
ModVer:  Offset: 00001e14

  It happens with 0.6.0-test1 but not with 0.5.3.
  I can upload file which produces such bug.

main debug: using demux module "ps"
libmpeg2 warning: invalid picture encountered  

  Another MPEG2 related problem. I've found that some of my videofiles
  are not played correctly at all with any versions of vlc.

  Crash looks like this:
AppName: vlc.exe         AppVer:         ModName: unknown
ModVer:  Offset: 007300a1
  but it should be related to libmpeg2 too.
  Elecard MPEG2 decoder and PowerDVD play these files without any
  problems. They are encoded with TMPGEnc (ver.
  Sometimes it doesn't crash and shows rainbow blocked noise on the
  screen instead. In pre-0.6.0 versions video window was just closing
  after encountering some packet error (?). Now it's not closing...

  I can upload couple of these files but I think even 1 meg from start
  of each file should be enough to determine the problem.

  Verbose output shows this:
main warning: backward_pts != current_pts (16667)
main warning: stream periodicity changed from B[1] to B[2]  

  There should be CLEAR option for "Messages" window. Weird, menu is
  called "View -> Logs" but window says "Messages".

  I want to thank Gildas Bazin for test package created for me:
  It fixes my problem with delays and stops on P4-2.4ghz system. I've
  extensively tested it over the weekend and wasn't able to recreate
  random stop problems which were found in previous versions.

  There's a typo in verbose output:
  "avi warning: avi module discarded (invalid headr)"
  I guess it's header ;)
  While all probing results say "invalid", "no", "not" one of them
  es warning: ES module discarded (system startcode)
  You might want to rename it ;)

  Some of the users were talking about aspect ratios and resizing...
  There was
  You might want to get (nah, not again) http://www.gabest.org/mpc.php
  and see how keypad works for changing aspect ratios. You can also
  get their 16:9 and other presets. It's annoying to force video
  aspect ratio in preferences each time.

  This one is one of the most requested (after famous IV50, LOL):

  Is it really that hard? In SDL it's just one line of code...
  Something like that should exist in DirectX too.

  Changing video size using wheel... I don't personally like that
  idea. No players except BSPlayer have such behaviour.
  Usually wheel is used to change volume, but it might be a good idea
  to use key modifier to change something else (ctrl+wheel = window
  size, alt + wheel = seeking, shift + wheel = speed (like in
  powerdvd - 2x, 4x, 8x)).

  And that bug:
  is a really longrunner. It happens with most formats and broken
  seeking is really annoying, not to mention missing frame-by-frame
  advance (let's hope that at least somebody from the people who
  mentioned they are working on that will fix it).

  This one:
  is duplicate to
  or vice versa.

  That's it :)
