[vlc-devel] problem with avi file

[Michael Pron]

I think there's a problem in the avi demuxer.
when we use input_Seek, we can't move in the file using the
INPUT_SEEK_SECONDS case. The typical example came when we tried to use
the "go to..."(in French "Sauter à..." ) option of the contextual menu of the gtk interface.
When using it, we simply go to the beginning of the file, in all cases.
So i discover that there was'nt any computation of the demuxer rate in
modules/demux/avi.c witch result in a zero value of
p_input->stream.i_mux_rate in src/input/input_ext-intf.c.

Looking at what was done in the past versions I propose a patch that
solve the problem.
