Permanent link Good free tools

Video player: Media Player Classic Homecinema with FFdshow tryouts. Setted-up with 24 bits 5.1 output, that my sound card output nicely on my headphones.
Music player: Foobar ; or Winamp with MAD or FFdshow
Wav editor: Wavosaur, free and feature comprehensive. Supports 24 bits, 7 channels wavs...
Video editor: VirtualDub
MP3 compressor: Lame on the command line.
Convert FLV/Avi: FFMpeg, with some GUI like WinFF.
Video capture from desktop: CamStudio

Permanent link MP3: Foobar 2000. Or libMAD

My favorite music player is now Foobar 2000. Some extensions I like:

Other good choices:

Winamp with libMAD 2 MP3 decoder. Original libMAD site.
Winamp with Ffdshow.

Winamp is easier to use. Foobar has better quality out of the box ; unless one uses libMAD or Ffdshow. MAD is one of the best MPEG audio decoder, the only one having an error rate under 10^-7 (neither Foobar nor Ffdshow are compared on this list unfortunately).

Permanent link 5.1 3D sound on headphones

Windows - Ffdshow

In FFDShow audio properties, open the mixer properties, and switch on headphone output and HRTF.
Or: use NVidia Purevideo audio decoder or PowerDVD filters. Or buy a X-Fi soundcard which supports CSS3D-Heaphones.
Also other sound cards like Nforce and Realtek SoundMAX also have 3d sound emulation on headphones. Set your headphone configuration as 5.1 in Windows, and as headphones in the soundcard tools or drivers.

Linux - Mplayer

mplayer -channels 6 -af lavcresample=48000,hrtf

Permanent link Linux and videos

Hardware acceleration on GeForce 6200/6600/6800/7300/7600/7800/7900

Create the file /usr/X11R6/lib/XVMCConfig and put int the following line: /usr/lib/libXvMCNVIDIA_dynamic.so.1 To see a video in mpeg2 format (dvd, .mpg or .ts file):

mplayer -vo xvmc -vc ffmpeg12mc file.mpg

Xine

xine --post unsharp:luma_matrix_width = 3, luma_matrix_height = 3, luma_amount =2.0, chroma_matrix_width = 3, chroma_matrix_height = 3, chroma_amount =2.0

Also see contextual menu/Video/Post-effect/Reaction.
Xine pros: graphical GUI, quite complete. Xine cons: cannot read DVDs which are CSS-protected.

Mplayer

mplayer -vf unsharp=l3x3:1.5:c3x3:1.5 Video.avi

It can read almost any videos. But it's command line-based, and GUI usually are quite poor.

Useful keys:

Left/Right, Up/Down, PgUp/Down: forward/backward by a few seconds, minutes, several minutes
v, j: activate and setup subtitles
Space: pause
q: quit
f: fullscreen
o: Onscreen display (none, user actions, always display time)
a: subtitle position
Shift+T: on top of other applicaitons

mencoder -forceidx \

			 -vf scale=420:236 \
			 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames \
