No audio stream when using ffmpeg to convert wmv files?
This thread on the ubuntu message boards was extremely helpful for me. I’m using a server with Ubuntu 8.04. The short version of what I had to do was install libmp3lame-dev from the http://debian-multimedia.org/ repository (follow the instructions there) because it couldn’t be found in the Ubuntu repositories despite assertions on the message board that it’s part of multiverse. So, you get that installed. Uninstall ffmpeg. Then follow these instructions to compile ffmpeg from source (I didn’t do the x.264 stuff since I’m only encoding to flv). After all the install stuff is done, I still had to copy the newly installed ffmpeg binaries from /usr/local/bin to /usr/binin order to get the web app I’m using to find it. Best of luck to you all. It took me about 3 hours to get to this solution. Yay.
