[MPlayer-users] Flv seeking woes, revisited

[Dennis Nezic]

mplayer still has trouble seeking in flv files.

ie. http://www.youtube.com/watch?v=ck-z4-B8_5k
(if you can rip the .flv file with a tool like clive)

Seeking seems to work with ffplay:
FFplay version 0.6,
  libavutil     50.15. 1 / 50.15. 1
  libavcodec    52.72. 2 / 52.72. 2
  libavformat   52.64. 2 / 52.64. 2
  libavdevice   52. 2. 0 / 52. 2. 0
  libavfilter    1.19. 0 /  1.19. 0
  libswscale     0.11. 0 /  0.11. 0
  libpostproc   51. 2. 0 / 51. 2. 0

Not so with mplayer:
