[Vnc2swf-users] Res: Unable to export flv to common format using edit.py or converting flv with ffmpeg

[<lfk...@ya...>]

Hi,=0A=0AFLV videos can be encoded in two different formats:=0A1) Sorenson =
H.263 Bitstream Format: "This format is based on H.263, an open video encod=
ing standard maintained by the ITU. The Sorenson H.263 video format was dev=
eloped by Sorenson Media (www.sorenson.com). Existing products that can pro=
duce Flash video are the Macromedia Flash MX authoring application, and Sor=
enson Squeeze for Macromedia Flash MX, a professional video compression app=
lication. It may also be possible to license the Sorenson Spark codec to pe=
rform Flash video encoding; contact Sorenson Media for details."=0A2) Scree=
n Video Bitstream Format: "As of version 7, an additional video format, cal=
led screen video, is available. This is a simple=0Alossless sequential-bitm=
ap format with blocked interframing. It is designed for sending captures of=
 computer screens in action."=0A=0AWell, pvnc2swf uses Screen Video Bitstre=
am Format, which was specially designed for screen capture, while the other=
 format (Sorenson H.263) is designed for motion videos.=0A=0AEdit.py can ge=
nerate MPEG movies. Check the options.=0A=0ARegards,=0A=0ALuis Fernando=0A=
