<div dir="ltr">Dear Sebastian,<div><br></div><div>If I set the faststart property to yes in Windows, the output file is created but the size remains 0. I enclosed the python source I'm using. You will need livestreamer to test it though. I have gstreamer 1.2.3 and python 2.7 (32 bit) on a 64 bit windows 7 computer. Plugin wise I'm using the uridecodebin, the encodebin and the filesink came with gstreamer. My statement is that neither the quicktime nor the iso variant of the mp4mux generates valid files if faststart is false. (Neither under Windows nor under Linux.) If I switch faststart to True, it is working fine in Linux but not in Windows. If I create iso-fragmented variant, it is fine both on Linux and windows. To set up the recording format please change line 42 and lines 50-53 in the python source.</div>

Setting faststart to true on Windows does not help either?<br>
<br>
Can you provide your sample code to reproduce this problem, either here<br>
or in a bug report? Also which versions of GStreamer and the plugins are<br>
you using?<br>
