The fact that video size is recuded means that flv module in nginx works
fine.

As I already said using arbitrary byte positions in the "start"
argument isn't possible with flv, you have to use positions of a
keyframe/seekpoint there. With arbitrary byte position broken
video is expected result.

If seeking doesn't work from a flash player, most likely reason is
problems with flv file itself. In particular, please refer the
the note here:

http://www.longtailvideo.com/support/jw-player/jw-player-for-flash-v5/12534/video-delivery-http-pseudo-streaming#mechanism

: Note: Some FLV encoders do not include seekpoints metadata when
: encoding videos. Without this data, HTTP Pseudostreaming will not
: work. If you suspect your videos to not have metadata, use our
: Metaviewer plugin to inspect the video. There should be a
: seekpoints or keyframes list. If it is not there, use the FLVMDI
: tool to parse your FLV videos and inject this metadata.

(The page itself contains appropriate links, quoted here just
clarify which note I'm referring to.)
