BBC iplayer

[eyegor]

Hello,

I was wondering if anyone can help me with this. I can usually rtmpdump most of the HD files available on BBC iplayer, but lately it's either very very slow or stops downloading altogether at certain percentages.
I tried download a video recently and it gives me an error:

RTMPDump 2.4

INFO: Connected...
ERROR: Closing connection: NetStream.Failed

I use the same parameters I've always been using and there's never been a problem before. So, can anyone please tell me if I'm doing anything wrong? Or if there is something that I need to do that I'm not aware of? Here's a sample of the parameters that I've been using:

/usr/local/bin/rtmpdump -r "rtmp://iplayertokfs.fplive.net:1935/iplayertok" -a "iplayertok?token=c3RhcnRfdGltZT0yMDE1MDIwNDAyNTM1 NyZlbmRfdGltZT0yMDE1MDIwNDA2NTM1NyZkaWdlc3Q9Mjk3OW Q5N2VlMWExMjg2OTY0OGU5ZDcyMzY4M2M2ZjY=" -f "MAC 16,0,0,296" -W "http://emp.bbci.co.uk/emp/SMPf/1.10.16/StandardMediaPlayerChromelessFlash.swf" -t "rtmp://iplayertokfs.fplive.net:1935/iplayertok?token=c3RhcnRfdGltZT0yMDE1MDIwNDAyNTM1N yZlbmRfdGltZT0yMDE1MDIwNDA2NTM1NyZkaWdlc3Q9Mjk3OWQ 5N2VlMWExMjg2OTY0OGU5ZDcyMzY4M2M2ZjY=" -p "http://www.bbc.co.uk/iplayer/episode/b0520v1w/count-arthur-strong-series-2-5-still-life" -y "mp4:3200kbps/modav/bUnknown-19dc8e93-45ad-40e1-8f85-731f6184ac27_b0520v14_1422825736500" -o "video.flv"

I am using MacBook Pro - OSX Yosemite 10.10.2
I really appreciate it if anyone can point me towards the right direction.Thank you in advance!
