Show the complete output of:

Code: Select all

ffmpeg -i input1 -i input2

Re: Multi bitrate streaming

Use the tee muxer : Since the audio is going to be the same for all outputs encode it only once and use it for all outputs Save a local copy with little extra overhead Use efficient filtergraph design to minimize filtering Optionally: Add the fifo muxer to re-connect on failed connections ffmpeg -i ...

Re: Recording and watching a stream simultaneously

Let me ask the question differently then. What muxer and encoder(s) are you using? If you are unsure then provide the complete console output from the ffmpeg command. Please copy and paste the text instead of making an image of the text.
