How to set codec for video output via MPEG-DASH?

Question

fmpeg

Hey All!
I'm trying to set up a webcast via MPEG-DASH according to this article:
habrahabr.ru/post/204666
I take the video from the camera like this:

avconv -f video4linux2 -i /dev/video0 -c:v libx264 -profile:v baseline -c:a libfaac -ar 44100 -ac 2 -f flv rtmp://localhost:1935/myapp/mystream

the manifest file and stream slice files are created,
but when trying to display them, Chrome (Chronimum 38) gives an error:

Codec (video/mp4;codecs="avc1.42c01e") is not supported

and the video is not displayed
the question is how to correctly set the codec to display the video?
Thanks
