A simple way to get the jre without going through the headaches of oracle’s disabled direct downloads is this:
wget --no-cookies --no-check-certificate --header "Cookie: oraclelicense=accept-securebackup-cookie" "https://download.oracle.com/otn-pub/java/jdk/7u65-b17/jre-7u65-linux-x64.tar.gz"
You can check the latest links by going to Java SE Runtime Environment 8 Downloads Page for example ( others available on the Java SE Downloads Page ), clicking ‘Accept License Agreement’ and copying the links of the wanted files.
So .. I’ve been wanting to see some youtube tuts/audio offline while I comute ..
But the volume is pretty low, either from the video .. or my android tablet .. and I know I can raise the volume from the DSP Manager but I don’t want to need to change it back again for other videos ..
Here’s how I did it on my gentoo system.
# you might want to unmask a newer version
# echo '<=net-misc/youtube-dl-2014.10.18 ~amd64' >> /etc/portage/package.keywords
# Here's how you get the mp3 only version
youtube-dl https://www.youtube.com/watch?v=QzQkpCX5pMU -x --audio-format mp3
This is the easy part !
Now, you probably want to raise the volume a lil’ bit ..
ffmpeg -i file.mp3 -vol 400 output.mp3
# 256 is normal, if you use 512 then it will double the volume.
# you can't use -acodec copy because -acodec copy and -vol are incompatible (frames are not decoded)
