I have tried the following URLs, using the streamio wrapper for FFMPEG. The URL's are
http://static.bouncingminds.com/ads/5secs/baileys_5sec.mp4 (works)
http://techslides.com/demos/sample-videos/small.mp4 (doesn't work)
For the latter I get the following error:
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height
The code I use to transcode them:
movie.transcode("test.webm", "-vcodec libvpx -strict -2") { |p| puts p }
As mentioned this works perfectly for the first video. Is there any specific setting I need in order to work with all mp4 videos?
