[FFmpeg-devel] [PATCH] flv duration

When playing an FLV, you always see this message:

[flv @ 0x120cea0]Estimating duration from bitrate, this may be inaccurate

even if the FLV metadata provides the duration. I'd been ignoring this for the 
most part, but after someone else mentioned it on irc I decided to take a 
look. The FLV demux sets the AVFormatContext->duration based on the metadata, 
but the av_has_duration() function wants to see it set in one of the 
AVStreams. It looks to me like it does no harm one way or the other, but I 
wrote this patch just to shut up that diagnostic.
