On that topic, I tried making a .flv video that uses h264 format. The
video was encoded using mencoder and x264. The video plays fine with
VLC, but when I want to inject metadata in the video using flvtool2, I
get the following error message:
--
ERROR: IO is not a FLV stream. Wrong signature.
--
Is it coming from the metadata that is positionned at the end of the
video file instead of at the beginning?

Did anyone manage to create a streamable flv video with h264 format?
