Convert flv to mp4

[btpoole]

I need some help please. I am using rtmpdump to download a live stream. I need to convert the live stream to mp4. I need it to be done with a command line tool, something that can be initiated and terminated thru a batch file. After some more reading I think using ffmpeg to listen for rtmp might be the way. Any help on the syntax to do this.Thanks

As suggested what I need is to convert or transcode the rtmp to mp4 as it's being streamed.

It depends on what codecs are being used in the FLV. IF they are compatible with MP4 container (e.g. h264 video/aac audio), it would be best to stream copy it (faster, no quality loss)

ffmpeg -i input.flv -vcodec copy -acodec copy output.mp4

But I don't know how to do this for a live stream (only after the dump has finished) . And if that's what you need, consider editing the thread title to something more specific

Thank you. Yes, that's what I need.
