Windows stream to MP4 crashes

I have found this problem on two entirely different installations of VLC 0.9.8a on Vista.

Steps to reproduce:
1) Open capture device (test by playing it)

2) Select option to stream

3) Paste the following stream options in the text box at the bottom of the Stream tab

Code: Select all

:sout=#transcode{vcodec=h264,vb=100,scale=1,acodec=mp4a,ab=128,channels=2}:duplicate{dst=display,dst=rtp{dst=239.255.12.42,mux=ts,port=1234}}
4) Press "Stream".

The same encoding and streaming settings work OK on Linux VLC 0.9.8a without crashing.

Interestingly, by mistake I put an "A" in the vb setting and it didn't crash. So this string works, albeit with unregulated video bandwidth.

Code: Select all

:sout=#transcode{vcodec=h264,vb=A100,scale=1,acodec=mp4a,ab=128,channels=2}:duplicate{dst=display,dst=rtp{dst=239.255.12.42,mux=ts,port=1234}}
The example shown here multicasts via RTP but I have experienced the same problem trying to send a unicast stream to a Wowza server.

0.9.x on Windows (still) has a problem with x264 encoding. Please use 0.8.6i.

Thanks. I just tried 0.8.6i and it works fine.

I know that earlier versions of 0.8.6 didn't work in this particular application, which is as an uplink to a Wowza streaming server. I think I had tried 0.8.6d before and just got a blank picture.
