VLC can't play .ps file transcoded from VLC
Posted: 04 May 2011 08:15
Hi-
I've been playing around with transcoding the live video feed of the earth from the International Space Station which is pretty sweet.
Anyway, today, with 10 minutes to spare I realized there was going to be a pass right over San Francisco but was away from my Mac where I've successfully transcoded it to mp4 before. I quickly installed VLC on a PC and went through the streaming wizard.
While I thought I had selected .mp4, the output was a .ps file. It's certainly the right size (about 16MB for 5 minutes of 640x480) but I when I open it in VLC I get no video, just a moving cursor along the scrubbing bar. I've tried converting in Handbrake but no luck.
The codec says mpgv (along with mp4a and mpga for audio, not that there is any meaningful audio).
I suspect in the rush I hosed the export (a shame, really, since the pass was directly overhead and you could see from Oregon to Los Angeles) but I wanted to see if there was any hope in extracting the video. I've uploaded the .ps file here.
I've included the message log:
Apologies for any time wasted on this.
