I'm on Ubuntu 14.04 64-bit and have been successfully using get_iplayer from the ppa for over a month now. I download tv shows in the default mode (flashvhigh which is normally 832 x 468). Just lately I've noticed some shows are now coming down at resolution of 896 x 504 which unfortunately results in avconv being unable to convert and ending in error:
It appears ffmpeg is no longer easily installable in Ubuntu 14.04. I tried a static ffmpeg build to manually convert the flv to mp4 and it worked although with warnings about "negative cts, previous timestamps might be wrong"
Any ideas?

$ get_iplayer -g 724
