[FFmpeg-devel] Defect #8801

[John Rose]

  Is your issue reproducible with current FFmpeg git head, the only version
  supported on this bug tracker?

As I'm a Newbie to this mailing list, I'm not sure that I'm doing it 
properly.
I was asked the above question by email from trac at avcodec.org.

As I stated in my defect report, I'm using ffmpeg 3.4.6. I don't know 
how to find out the version of ffmpeg on the current ffmpeg git head. 
Please advise me how to find that out and if it's different to the one 
I'm using how to change my ffmpeg version from that supplied by Ubuntu 
on Bionic (i.e. 18.04).
