I need to create a feed that has two streams - webm and mp4 - so that it can be compatible on all HTML5 video players. The webm stream works perfectly. However, when trying to access the mp4 stream, the server spits out the following error:
Sat Mar 9 23:21:54 2013 muxer does not support non seekable output
Here's the portion of the ffserver.conf file that deals with the mp4 stream:
<Stream channel1.mp4> # Output stream URL definition Feed feed1.ffm # Feed from which to receive video Format mp4 # Audio settings AudioCodec libmp3lame AudioBitRate 64 # Audio bitrate # Video settings VideoCodec libx264 VideoSize 560x320 # Video resolution VideoFrameRate 25 # Video FPS AVOptionVideo flags +global_header # Parameters passed to encoder # (same as ffmpeg command-line parameters) AVOptionVideo cpu-used 0 AVOptionVideo qmin 10 AVOptionVideo qmax 42 AVOptionVideo quality good AVOptionAudio flags +global_header PreRoll 15 StartSendOnKey VideoBitRate 400 # Video bitrate </Stream>
From what I can find, some people are saying that mp4 simply cannot be streamed. I have no attachment to mp4, except for the fact that I was under the impression that you needed mp4 to stream video to the iPhone with an HTML5 video player. If this isn't the case, let me know and I'll gladly switch to something that plays nicer with ffmpeg streaming.
