Hy Opus lovers. New forum, new challenges, big posts...

I need help again.

I have some videos in mpg and swf to insert in my program. I made a video player with buttons for forward, rewind, pause and play the videos.

My biggest challenge now is how to put a slide bar to move forward or backward tracking the position of the video that is playing from beginning to end, as does the slide bar in windows media player. Likewise, if the user clicks somewhere point in the bar, he goes to the point equivalent of the video.

I did some search on the topics of the forum but found nothing similar.

Any suggestions on how to make this possible slide bar functional?

I,m using Opus 6. Thanks...

Hi Nilson,

Video slide-bar/tracking-bar is one of those things that is takes some creativity and resolve.

It's not too difficult to get something working. However IMO there is a great challenge in getting the tracking-bar to work smoothly and reliably (while video plays and while it is paused).

Best recommendation is in this post: viewtopic.php?f=6&t=4024

Lar, thanks for the indication. But... The example that I downloaded from the site interaktiv (vcr.exe), along with some codecs do not work in my seven 64. The mpgs that I have fought, and moreover, must also be free to play swf files in which there are embedded videos in flv format.

So the challenge is much bigger than I thought. Opus has commands in script to give the possibility of controlling the video object via buttons, but a slide bar, for what seems to be something much more complex, bacause the player that I use needs to be incorporated within the slides of the program.

I thought about making a slide bar working like a clock, with the same time the video being played on the player, because each video to be inserted in a slide program has already a determined slide. In this case, the buttons to pause / play, forward and rewind could control both objects.

Again, the space bar still remains a major challenge. As you click a point on the bar and have the same equivalent point in the video? If the time bar is determined by the time of the video, I believe it may be possible to find the control for both ...

I'll call some more facts to be analyzed. Anyway, any help in this direction is welcome.

The VCR was published under Opus 6.0. It will work under W7x64 if published from Opus 7.0.

As for codec support, it was created to play & control MPG1, WMV & MP3s but because of the way Opus works, will play most formats if the correct codec is installed. However, the success of controlling a video format will depend on the format, the codec and the way these work with Opus. On this system, MPG2, MPG4 (h.264) all load, play and navigate fine in Opus. SWF & FLV play, but navigate very badly but then it may well be the encoding as we rarely use this format for video but then as the aforementioned basically covers VCD / DVD & HD quality, everything else is surplus.

Regards,

Mack

published with Opus 7.0 and added SWF for file browser (not recommended).

Well, I think I will have to contend with the flash. So, I'll see if I can make a functional flash player, with files flvs. Flv's compression is much greater than Mpg's and results in a smaller final file to be inserted in the program. As always, the biggest challenge will remain the control bar of the video, which will depend on programming.
I do not know if all the action script commands are accepted by Opus. There is the question. Opusscript or actinscript ...

Well, I have found the solution in one of the posts here in the forum. I'm working on the player, whose control buttons, with the slide bar control are becoming functional. Once you're done, I put the file. Thanks for your model, Duncan Lilly!!!!
