On March 29 I committed a patch that allows to set the tv standard. By
default, ffmpeg sets the ntsc standard, unless you specify a different
tv standard by using the "-tvstd " option. Can you try "-tvstd pal" to
see if it fixes your problem? If not, can you try commenting out the
if( v4l2_set_parameters( s1, ap ) < 0 )
lines in v4l2_read_header()?
