BBC iPlayer AAC Radio streams now available using get_iplayer

It’s just been pointed out to me the after much waiting, the BBC have started to make AAC streams available for their listen again content on the iPlayer. The bitrates vary from 96 kbps to 128 kbps from what I can see. This will possibly result in better quality. AAC 128kbps can certainly be an improvement over the same bit-rate MP3 but it does seem that the BBC have reduced the bandwidth and quality to AAC 96kbps to save us a whole 32 kbps !! Oh well, you at least still have the choice between MP3 and AAC. Make sure you have rtmpdump installed to be able to download AAC.

In get_iplayer, the default order of trying to download a Radio programme is: iphone,flashaac,flashaudio and realaudio. You can explicitly specify to use AAC mode by using

get_iplayer --type=radio --amode=flashaac [other search options]

get_iplayer gets High Quality Flash BBC iPlayer RTMP Downloading Capability

Merry Christmas!

Another great feature has been added to get_iplayer. You can now download programmes from the high quality flash version of the BBC iPlayer (640×360 resolution) using the optional rtmpdump tool. This means that you will be able to download ANY programme as soon as it is available on the iPlayer Flash web page.

Andrej Stepanchuk has very kindly written and released rtmpdump. If installed, get_iplayer (v1.04 or above) can use it by adding the –vmode=rtmp option to any TV download. This feature is currently an alpha test.
Pre-requisites are:

  • Installation of rtmpdump
  • ffmpeg (to convert the flv file into mp4 format)

You can get rtmpdump here (compiled for Linux/x86-32bit, MacOSX/x86 and cygwin). The Home Page and C++ source is here. I recommend you compile your own – it is very easy – just make sure you have the boost libraries installed.

In get_iplayer you’ll need to specify the location of rtmpdump binary (using –rtmpdump) if it is not already in the path.

Let me know how it goes.

Update (28th December 2008)

Andrej has released rtmpdump-v1.1 this addresses issues with 64-bit Linux and adds download resume support. Use in conjunction with the latest get_iplayer 1.05 or newer.

If you come across problems specifically related to rtmpdump (i.e. not get_iplayer) you can post them at the Sourceforge page for rtmpdump.

Update (2nd January 2009)

For get_iplayer 1.09 and above to use the RTMP features you’ll need rtmpdump-v1.2+ this addresses issues with Normal quality RTMP Flash downloads and adds download resume support for this quality.
