<DIV><SPAN class=156210303-15052006><FONT face=Arial size=2>I have attached a
patch which I have been working on to honour the Scale header in RTSP requests
received by VLC. At present, this header is parsed from RTSP PLAY
requests, but only acted upon when VLC playback has been paused (and this PLAY
command is intended to resume playback). This is a very simplistic patch,
simply changing the rate value of the p_input input_thread_t structure - However
I have run into a problem whereby this rate value for UDP playback (to Amino
set-top boxes) cannot be changed as a result of the following condition in
src/input/input.c</FONT></SPAN></DIV>

<DIV><SPAN class=156210303-15052006><FONT face=Arial

i_rate != INPUT_RATE_DEFAULT
&&<BR>
( !p_input->b_can_pace_control
||<BR>
( p_input->p_sout && !p_input->b_out_pace_control ) )
)<BR>
{<BR>
msg_Dbg( p_input, "cannot change rate"
);<BR>
i_rate =
INPUT_RATE_DEFAULT;<BR>
}<BR></FONT></SPAN></DIV>
<DIV><FONT face=Arial size=2><SPAN class=156210303-15052006>This conditional is
being triggered as a result of the b_out_pace_control being set to a false value
as a result of modules/access_output/udp.c setting i_out_pace_nocontrol to true
- Modifying this value gives variable results where at times, playback rate is
modified, but at others it is not. </SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=156210303-15052006>Can anyone shed some

<DIV><FONT face=Arial size=2><SPAN class=156210303-15052006>Alternatively,
perhaps my question is as to whether there is another approach which I should be
looking at in order to modify playback speeds?</SPAN></FONT></DIV>
