[Libav-user] how to send new metadata to rtmp stream by flv muxer

[qw]

Hi,


I have one question about ffmpeg lib usage. If rtmp url link is used as input and ouput address, then flv muxer/demuxer and rtmp plugin will be chosen to process av stream. At the beginning, one onMetaData message will be sent to output rtmp stream. But in the middle of time, I want to update av information, such as bitrate and frame rate. How to send another new onMetaData message to output rtmp stream? and What ffmpeg functions can be used to send the message?


Thanks!


Regards


Andrew
