Betaplayer is a great piece of soft, but it still lacks one feature that keeps me from using it exclusively: an alarm/snooze function! Yes, I love to fall asleep to music, even if the sound comes from my tiny X50v speaker. I also enjoy waking up to music, as opposed to a beep, bling, or whatever other funky sound is included in the OS.

I currently use Mortplayer for this reason alone. If Betaplayer could include this feature, I would never touch another movie/music player again. I swear!! ;)

edit*** well, i was going to post a screen capture of the option page but the forums won't let me post anything larger than 450x450 and i can't figure out how to shrink it anymore without losing the legibility... i'll try to figure it out tommorrow i guess...
Get a freeware program called IrfanView. It will shrink it down to the required size and it's easy to use.

We found that one of the problem here is that Betaplayer does not release the 2700G video hardware when it becomes de-activated (i.e. Minimized or hidden in the background).

This is an extract from the PocketTV release notes:

Quote:
PocketTV automatically powers off the 2700G video hardware accelerator chip when the application is Minimized (i.e. de-activated in the background). So you have no risk of draining your battery faster just for having PocketTV sleeping in the background. Note that Betaplayer does not power off the 2700G when it is in the background.

Note that if you also use Betaplayer, you should first Exit Betaplayer (using the Exit command in the menu) before starting PocketTV. That's because Betaplayer does not release the 2700G hardware when it is Minimized. So if you have Betaplayer running in the background (i.e. Minimized and invisible), you need to Stop it completely (Exit) before starting any other application using the 2700G (e.g. PocketTV). On the other hand, PocketTV does release the 2700G hardware when it is Minimized. So it does not prevent you to start Betaplayer. Hopefully the Betaplayer people will correct this problem so that they can co-exist better with other applications using the 2700G.
Naturally this does not affects the battery life while playing video, but it certainely affects it after you tap the (x) button or start another app.

When playing video with the 2700G (with Betaplayer or PocketTV), you can set the CPU speed to "Normal" to save power. "Power Saving" will save more power but is marginally sufficient to play full framerate video.

Screen and buttons then are locked and have no response, necessitating a soft reset..

I haven't posted about this, since it is minor and only happens occasionally, but was wondering why nobody else has mentioned it.. Has this happened to anyone else? or is it just me..
I can confirm those issues, we have observed the same in PocketTV, and in most cases we have found workarounds.

Apparently those are mostly caused by race-condition problems in the 2700G driver from Intel and Dell.

For example, I noticed that pressing the POWER button while Betaplayer is playing (on the x50v with the 2700G) often locks-up the device, and a soft-reset is necessary to turn it back ON.

Incorrect! VCD are encoded with MPEG-1 :)

I noticed a bug with the "benchmark" feature of Betaplayer:

Sometimes it skips B-frames, leading to totally incorrect (very high) benchmark results. Picard acknowledged this one, but the bug is apparently still randomly there.

Thanks. It's already on my todo list.

In fact both PocketTV and Betaplayer still have the problem with the ATI hardware, which we don't release when we are de-activated.

This appears to be a problem with several devices that have a camera: The camera does not work when the ATI driver is being used (probably because it requires all the available ATI memory ?). And people get puzzled by the camera error, which goes away after a soft reset.

The problem is that many people think that by de-activating/minimizing the app using the X button in the nav bar, it closes the app - it makes it go away, so in people's mind, it's not there therefore it is closed!

That's why in general it's a good idea to release as many resources as possible that are not used when the application in is the background (e.g. close any opened file not actively used, etc). For example, we close the video file when de-activated, this way people don't get bizare errors when trying to copy or erase the file. Of course this add complexity since the app must gracefully deal with possible errors when trying to re-grab all the resources they have closed, when they get re-activated.

So I think we should also do the same and release all the ATI resources when we de-activate.

What do you think ?

I agree. I know you mentioned it way back about the waveout device release, but BetaPlayer still doesn't release it in the background. I will add that too.

Yes, file closing is a nice feature too (not done by BetaPlayer yet)

ps: for few weeks I won't have any time developing the player...

I believe there is some royality problem with mpeg2, you have to pay to use the format i think..

Most probably, you will have to transfer it to SD/CF card to get it to work. Still, it's better than having to re-encode files.

Anyway, I wish PPCs would start using 802.11g or something, or at least get the processor speed/bus speed fast enough to fully utilize 802.11b speed, and not just 1-2mbps of it :(
Hmm i tried a few divx movies from my download folder, i was even pretty far away from the AP and the files played att 300% on benchmark over 802.11b..

And BTW, thanx picard for such a lovely program, i would donate some $ if i had any =/

Same with MPEG-4 and MP3, BTW. Yes, MPEG-2 patents royalties are strongly enforced by MPEGLA.

There are several MPEG-2 and DVD open-source project, mostly linux-based.
