javascript - Converting fragmented mp4 file for MSE (Media Source Extensions) -

i'm looking way generate proper fragmented *.mp4 files mediasourceextension (chrome).

i tried out illustration here: http://people.mozilla.org/~jyavenard/tests/mse_mp4/paper.html , given video file worked fine.

so tried out settings avconv / mp4 box own video files working, i'm getting video errors...

avconv -i file -c:v libx264 -c:a aac -f mp4 -movflags frag_keyframe+empty_moov output.mp4 mp4box -rap -frag-rap -dash 30000 -segment-name out.mp4 output.mp4

chrome media-internals says: error skipping unrecognized top-level box: ftyp

so know how convert them properly?
