@C1@c@b@_ MPEG Control
MPEG player with some manipulation capabilities.
@b Interaction
Click on Play to play frame by frame non-stop. When the video stream
ends, program will stop. For infinite looping, click on play & loop.
Click NextFrame to play the next frame.
A frame can be displayed magnified by various factors,
click on the top-left rounded box to change to a different
magnification factor. Default is 2x2.
A delay can be added between each frame (who wants to do that, I
wonder as MPEG is always slow). Click on the the box to the
right of the magnification box.
To convert the current frame to another format, click on the Convert
button. The converted image will be written to "current directory",
which is the same directory as the MPEG file is in (thus, if you start
with bit ../movie/1.mpg, then the converted image will be in ../movie).
To convert all frames, starting from current current frame, click on
ConvertAll button. Depending on the converted image types, this could
use a lots of disk space (for a 200x100 framesize with 300 frames, you
need ~20Mbytes for uncompressed frames).
Click on Stop to stop whatever the program is doing.
Click on Done to finish and close the video stream. Note if the
player is playing in non-stop mode, click on this button is the
same as Stop.
Pressing ESC key inside the main window is the same as clicking
on Done button.
@ Note
The MPEG player is based on the Berkeley source.
Random seeking is not working so is the PrevFrame. Currently
PrevFrame is the same as NextFrame.
Despite a lot of hacking, the player is not as stable as I would like.
