Licensing Pain

It’s a very long time since I’ve used any software that requires a licence but I decided to try the patented MPEG2 codec licence for my Raspberry Pi, to decode MPEG2 in hardware. Now I remember why I disliked software licensing so much. This was the process I followed for the Pi’s default Raspbian operating system.

Step 1: Find my Pi’s serial number. At the command line, type:  cat /proc/cpuinfo
The last line, starting Serial: is the unique number of your Pi.

Step 2: Find where to buy it. http://www.raspberrypi.com/license-keys/
Enter the serial numer of the Pi you wish to buy the licence for..
Pay £2-40 and wait for an email. It may take up to 72 hours. I assume this is because a unique(ish) key must be generated.

Step 3: Add the following line to “the config.txt file in the FAT partition of your SD card:

decode_MPG2=0xfdb4a3ac” You may note that this is not the 10 digit hex you were expecting. That doesn’t matter. The first two digits must be implied zeros.

Others told me this meant sudo my chosen editor to add the line to /boot/config.txt then save and reboot.

and “If you want to verify that the codecs are now enabled, the following commands will report their status:

vcgencmd codec_enabled MPG2”

Step 4: Wonder why that didn’t work.

In my case, I was typing:
“vcgencmd codec_enabled mpg2”. It said mpg2 was disabled. In reality, there was no “mpg2”, because it’s “MPG2”. Case matters.


The Value of Software

I’ve been reminded of the fastest 1980s transatlantic software delivery method:

  • Put software on a magnetic tape.
  • Put the tape in your hand luggage.
  • Fly to the USA.
  • At customs, when asked if you had anything to declare, say “This tape”. If asked the value of the tape, make a fast decision whether to say $10 and risk 12 hours of interrogation as a possible communist spy, there to steal America’s software secrets or say $150,000 and be sure of an hour of form filling.

It has occurred to me that the correct answer was:
“$10. The licence costs far more but I’m not carrying that. It will be sent on later.”

Software is worth nothing until you use it and only until you stop using it. Free software costs nothing, so developers need to get paid in a different way. Should Free & Open Source Software be paid for only by those who use it to generate a profit and could it generate an international income for the countries that fund it, adjusted for national wealth?

Could we have a licence to receive free software updates, only paid for by businesses, according to their income (before tax fiddles) and routed to the teams that developed the software that is most used? Commercial software could join the scheme too, with higher prices if less rights are handed over. I don’t think it is healthy for FOSS to kill the commercial software market, because it encourages anti-competitive service monopolies like Facebook and Google.
