Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma
You can get the list of supported formats with:
ffmpeg -formats
You can get the list of installed codecs with:
by default,openwrt do not allow ssh access from wan, here are two method to change that: | |
1.login into your wrt from a lan host.issue the following command: | |
iptables -F | |
the command "flush away" all the firewall rules,including the one that rejects ssh request from wan. | |
now you can try ssh from anywhere. | |
aware that the firewall deactivation leads to highly security risk.and after the wrt restarts ,all default firewall configuration comes back.you hava to "flush" the rules once again. |

# Here are a few methods for getting text from PDF files. Do read through | |
# the instructions carefully! NOte that this code is written for Windows 7, | |
# slight adjustments may be needed for other OSs | |
# Tell R what folder contains your 1000s of PDFs | |
dest <- "G:/somehere/with/many/PDFs" | |
# make a vector of PDF file names | |
myfiles <- list.files(path = dest, pattern = "pdf", full.names = TRUE) |
This gist contains all the OpenWRT configuraion files needed to connect to Private Internet Access (PIA) VPN servers. The following files are included:
network
: contains configuration to add a virtual network device (i.e. tun1366
) and custom DNS serversopenvpn
: OpenVPN configuration file to connect to PIA VPN serversfirewall
: firewall configuration which passes all traffic through VPN and rejects any request when OpenVPN is downNOTE: there are a number of other files required to be available under /etc/openvpn
for this approach to work:
pia.auth
: VPN credentials in two lines, first the username and the second the passwordmaking the ubnt wifi awesome (uap ac lite) w/ lede (openwrt) | |
the reasons you would do this: | |
- you get 802.11r | |
- you get better roaming | |
- you get access to some new 5ghz channels | |
I AM NOT TO BE HELD RESPONSIBLE FOR ANYTHING IN HERE. DO AT YOUR OWN RISK. THANK YOU AND HAVE A LOVELY DAY. | |
** note that though we're using Lede, it's essentially openwrt minus the drama |
