Thx for the help it worked, i use debian sid so Chromium Codecs dosn't exist. But easy to resolve anyway. -First step: I download chromium-codecs-ffmpeg-extra_45.0.2454.101-0ubuntu0.14.04.1.1099_amd64.deb (note i'm using amd64 version) -Second: i didn't install the deb, with a compressor app i open the file and extract libffmpeg.so -Third: You can make a symbol link or delete the opera lib and put the new one and rename it like the old one. Do you know when do developers fix it in linux? Thx in advance
