Looks like that I’m gonna get a free t-shirt!
Their service is awesome, but I can’t afford, for now, premium packages…

I’m preforming some benchmark tests on avconv in two different machines..
One is a cloud hosting plan, with a SSD disk and 512Mb of RAM, running Ubuntu 13.
I was having some troubles trying to make the first login on my Ubuntu Server…
No root, no root password… even the username that i’v created while setting it up wasn’t working… eventually after some 20 times trying it worked….. funny!
Root Password for Ubuntu Fresh Installation? There isn’t.
sudo
is the solution.

Amount of memory limited to 256MB – Strike F1 Key to continue / F2 to run the setup utility
WTF?
I was getting somehow alarmed with that error…. but I’v realized that it started to appear after I had enable OS Install Mode on bios… so, went there and disabled it.
This is how you check it
egrep '(vmx|svm)' --color=always /proc/cpuinfo
If you get vmx (intel) or svm – (amd) it does.
root@digitalwhores:/home# grep --color vmx /proc/cpuinfo
flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm rep_good nopl pni vmx cx16 popcnt hypervisor lahf_lm
XEN kernel? try
cat /sys/hypervisor/properties/capabilities
My PowerEdge doesn’t?! f*ck!
INTEL:
VT-x, shows in /proc/cpuinfo as the vmx flag. (grep vmx /proc/cpuinfo)

I’m having problems with avconv, especially exporting the video properties to json…
“Failed to set value ‘json’ for option”
I was able to create json files with ffmpeg, but since ubuntu uses avconv and ffmpeg is an aliase of avconv… i’m not able to create json files…. be struggling with it for 4 days.
This is how I’v installed FFMPEG 2.0 on my Ubuntu 13.
$ wget -c www.ffmpeg.org/releases/ffmpeg-2.0.tar.gz $ tar -xzvf ffmpeg-2.0.tar.gz $ cd ffmpeg-2.0 $ ./configure $ make $ sudo make install
If you start to have problems while trying to run ./configure…
apt-get install gcc
You will probably also need to install make
root@digitalwhores:/home/ffmpeg/ffmpeg-2.0# make The program 'make' is currently not installed. You can install it by typing: apt-get install make root@digitalwhores:/home/ffmpeg/ffmpeg-2.0# apt-get install make
An them go to ./configure from the initial instructions…
sudo ./configure --disable-yasm
make
root@digitalwhores:/home/ffmpeg/ffmpeg-2.0# ./ffmpeg ffmpeg version 2.0 Copyright (c) 2000-2013 the FFmpeg developers built on Sep 22 2013 10:23:36 with gcc 4.7 (Ubuntu/Linaro 4.7.3-1ubuntu1)
And now! remove the old ffmpeg/avconv!
Hasta la vista!
sudo apt-get remove ffmpeg
sudo apt-get autoremove
