I just got my chromecast and I am trying to convert my uncastable avi videos to castable mp4 video format I converted some avi videos to mp4 using the command:

avconv -i input_file.avi -c:v libx264 -c:a copy output_file.mp4

The problem is that I get the error "media not streamable" and won't work with chromecast.

I finally found the answer I was looking for here:

Bash script to convert multiple avi in to mp4

The important line in the proposed script is

avconv -i "$i" -vcodec libx264 -acodec aac -strict experimental  -threads 3 "$name.mp4"

changing "$i" for the input filename and "$name.mp4" for the desired output name.

Google Chromecast supports two container formats, WebM and MP4.
Therefore use WebM and the Google VP9 codec via the command below. Why WebM? Google VP9 doesn't works with MP4.

avconv -i input_file.avi -c:v libvpx-vp9 -c:a copy output_file.webm

or the VP8 encoder

avconv -i input_file.avi -c:v libvpx -c:a copy output_file.webm

  • I don't have libvpx-vp9 on my pc. I downloaded it from linuxfromscratch.org/blfs/view/svn/multimedia/libvpx.html but the installation instructions given in the README file a way beyond my capacities. Is there an easy way to install libvpx-vp9 ? – frepie Oct 14 '15 at 2:20
  • Try VP8 first, I have improved my answer. – A.B. Oct 14 '15 at 19:40
