Hi to all,
I got a problem while trying using the mms protocol:
I'm able to connect and see the video in play, but when I try to step
forward or rewind it don't work.
I try to develope an application that do the GOTO function, or Set Position
but if the player is in still it doesn't work, instead if the player is in
play status it work but I can't use for just 1 frame haead.
Does anyone know a way or a workaround to have the step by step (frame by
frame) capabilities using the mms protocol or better the rtsp protocol?
I can't use the http because its a use file and the bandwith is low.
There's not really a workaround. Are the files "indexed" ? It depends
on the remote server too,if these functions are enabled - but you can
check programatically if they are by using code such as
player.controls.isAvailable("step");
player.controls.isAvailable("fastForward ");
They return boolean true/false, so wrap your code in those before
attempting to use player.controls.fastForward() for example.
The available checks in the SDK are as follows :
=============================================
currentItem Determines whether the user can set the currentItem
property.
currentMarker Determines whether the user can seek to a specific
marker.
currentPosition Determines whether the user can seek to a specific
position in the file. Some files do not support seeking.
fastForward Determines whether the file supports fast forwarding and
whether that functionality can be invoked. Many file types (or live
streams) do not support fastForward.
fastReverse Determines whether the file supports fastReverse and
whether that functionality can be invoked. Many file types (or live
streams) do not support fastReverse.
next Determines whether the user can seek to the next entry in a
playlist.
pause Determines whether the pause method is available.
play Determines whether the play method is available.
previous Determines whether the user can seek to the previous entry in
a playlist.
step Determines whether the step method is available during playback.
stop Determines whether the stop method is available.
=============================================

Cheers - Neil
