[FFmpeg-user] generating a poster uses all my ram

Here's a working command to generate a poster

ffmpeg -y -i "http://nasatv-lh.akamaihd.net/i/NASA_101@319270/index_700_av-p.m3u8" -vf fps=1/60 -update 1 "./poster.png" -hls_time 10 -hls_list_size 10 -hls_wrap 10 -hls_flags delete_segments -hls_segment_filename "./video%03d.ts" -c:v copy -c:a copy test.m3u8 > test.log 2>&1 &

Here is the log: http://pastie.org/10659549

If I leave off the options -vf fps=1/60 -update 1 "./poster.png" it goes very fast....with these options enabled it eats up all my ram just to produce the poster.png file

Is it possible that you provided a script that does
not allow to reproduce the issue instead of the
actual command line including the complete, uncut
console output that allows to reproduce the issue
you see?
