Summary of the bug:
I am trying to stream a short video in raw format from a server at
San Diego State University. However, I am getting a segmentation
fault when I run the command line that I have printed out below. This
problem occurred while running the most recent release of ffmpeg.
How to reproduce:
The command line used was:
ffmpeg/ffmpeg -r 15 -s 320x240 -f rawvideo -i pipe:
http://marconi.sdsu.edu:809\
0/feed1.ffm < testvideo_1000f.raw
Below is the console print out using the -v 9 -loglevel 99 flags and also
with gdb running:
