Any .flv or .mp4 video stream can be watched while the stream is still downloading, using the command line utility FFPLAY.EXE
The build to use (with Windows XP/Vista/7) is FFPLAY release 16573 -
http://ffmpeg.arrozcru.org/builds/sh...-win32.tar.bz2
The ffplay syntax is -
ffplay.exe -bufsize 4096 *.*
The command line is (for example) -
"C:\Program Files\FFPLAY\ffplay.exe" -bufsize 4096 *.flv
If the stream is downloading as .mp4 rather than as .flv then change *.flv to *.mp4 instead
Put that command line in a .bat batch file (e.g. play.bat) and put the .bat file in the directory in which the stream is downloading, then run the batch file.
