I want to get a free codec displayer for FLVs.

I need to know what vid/audio codecs are used in FLVs I downloaded.
GSpot and MediaInfo are too old to work on FLVs.

If you can get it to play in VLC you can get the info there.
my windoze version 0.8.6i plays but my linux ver 0.9.9 refuses to
play .flv

Open the .flv in VLC. Pause it if you need to.
Right click on movie to bring up the menu then
bottom of menu is 'miscellaneous' -> 'media info' -> click on the
'advanced information' tab.

You get something like:

Stream 0

Codec: FLV1
Language:
Type: Video
Resolution: 320x240

Stream 1

Codec: mp3
Language:
Type: Audio
Channel: 2
Sample rate: 22050 Hz
Bits per sample: 16
General
Duration: 0:00:44

Which is about all the info available in the flv header.

If you want to look at the flv file with a hex editor.
following is pinched from the flv spec.

FLV header

Field Comment
Signature Signature byte always 'F' (0x46)
Signature Signature byte always 'L' (0x4C)
Signature Signature byte always 'V' (0x56)
Version File version (0x01 for FLV version 1)
TypeFlagsReserved Must be 0
TypeFlagsAudio Audio tags are present
TypeFlagsReserved Must be 0
TypeFlagsVideo Video tags are present
DataOffset Offset in bytes from start of file to start
of body (that is, size of header)


and so on................
