Please provide the patch in diff -u format.
Comment 3 Luca Ognibene 2005-06-27 12:14:55 UTC
As i've told you yesterday in irc ther is a problem with encoding (or decoding?). 
gst-launch-0.8 videotestsrc ! ffenc_flv ! ffmux_flv ! filesink 
creates a video with 1000fps. It plays fine with mplayer but 
gst-launch-0.8 filesrc ! ffdemux_flv ! ffdec_flv ! xvimagesink failes to
negotiate 1000fps. 
Comment 4 daniel fischer 2005-06-27 20:40:38 UTC
the 1000fps issue seems not related to this patch, or even flv encoding with
gst-ffmpeg (with this patch), macromedia's flash player detects the framerate
correctly. i would've patched the decoder too, but could not find the bug (yet).

flv streams have no framerate property in the header, it seems there can be a
metadata tag (AMF - 'action message format'). maybe it's defined by a duration
value on the flv_h263 picture header...

whatever of those, ffmpeg (the executable) detects 1000fps framerate on it's own
25fps movies, i suspect a bug in ffmpeg's flvdec (or h263dec).

will attach a new (-u) patch.
