| Home › Support › Breeze Help > "Read stream" options dialog box
|
This dialog allows you to enable / disable reading of input streams and set
their parameters.
There are two main panels in this dialog, upper panel and lower panel. Upper
panel is associated with the primary channel, and lower panel is associated
with the assistant channel. At the very bottom of the dialog there are also
additional controls associated with both channels.
The following options are available in this dialog:
"Enable reading" check box
Enables / disables reading of both channel independently on whether individual
channels are enabled or not.
"Enable channel" check box
Enable / disable reading for the individual channel, primary or assistant.
"File format" text box
This field shows a format of the stream open to the channel.
"Single image in file" check box
Files / streams of some types can be processed by two ways:
• As a file with just single image in file, or
• As a video sequences consisting of many images (frames) saved
in one file.
One popular example is YUV files.
"Single image in file" check box allows to specify how to process that sort
files / streams.
This check box is enabled only for the file formats wich can be used both ways,
as video and as single image file.
Breeze disables this check box for file / stream formats which can be processed
only as a video sequence or as a file with just single image in it. In that
case check box shows the type of file / stream open to the channel.
Configuration file
If this field is enabled it allows to select configuration file specifying
parameters of the channel and the stream open to the channel.
"Start frame" and "Stop frame" edit boxes
This dialog allows you to set start and stop reference frames used for playing
a fragment of video sequence.
If channel is open, and playing for channels is enabled, and command "Start" is
applied then video sequence begin to play. All frames placed within video
sequence before start reference frame are skipped as fast as possible. Skipped
frames are not displayed in the browser window.
Beginning from the start reference frame video sequence is played with normal
speed and all frames are displayed in the browser window, until the stop
reference frame is reached.
Playing is stopped when stop reference frame is reached.
To play very long video sequence without stops, set stop frame to some very big
number. Default value set by Breeze is 1,000,000,000. That value allows to play
video at the frame rate 30 frames per second during 1 year and 3 months without
stops.
Start and stop frames can also be set in the
"Reference frames" dialog available via the item
Set reference frames... of the "Tools" menu.
"Frame cache size" edit box
Use this edit box to set number of frames in the frame cache buffers for primary
and assistant channels.
Each channel has its independent frame cache buffer. Both frame cache buffers
have the same number of frames.
During playing video sequences frames are collected in the frame cache buffers
until buffers become filled completely. After that, the new coming frames
replace the very last ones. Collected frames can later be replayed from the
frame cache buffers.
