Re: Pdf Viewer For Blackberry Bold 9780
Anastacia Iacono
I download an MP4 file from the internet and play it on the blackberry device. I get the following error: "the video portion of the media being played uses an unsupported format". The audio starts playing, but the video doesn't play, while showing this error.
It should be noted that this only happens on Device OS 5 & 6. The same video plays properly or OS 7 and OS 7.1. I am guessing this is because RIM included some updates to MMAPI. What could i do to allow devices prior to OS 7 play the videos? OS 5 & 6 devices play MP4 files, just not all of them.
So, that explains why you can't get that video to play on the 9780. If playing this video is fundamental to your app, you might change the settings in BlackBerry App World to list it as incompatible with 9780s. If this is only one of many features of your app, you might at least catch the media exception and inform the user gracefully that their device can't play the video requested, so they don't think it's your app's fault.
It might be useful for you to produce the videos in a variety of formats and resolutions, and have your BlackBerry app download different versions of the video depending on the device. Since video downloads are slow, doing it this way will also ensure that the user sees the fastest possible download on their device. There's no use downloading a higher resolution than the device can display.
The BlackBerry Bold Touch 9900 has everything in the box to get you going. To get the basics out of the way, a charger, headset and a microUSB cable are all provided. But there's more: a leather pouch, cleaning cloth as well as Europe continental and UK plug adapters.
The BlackBerry Bold Touch 9900 is wider than its predecessor, the Bold 9780, as it has to accommodate a bigger display and battery. At 115 x 66 x 10.5 mm, it looks sharp and slim. The weight of 130g is more than reasonable - a mere 8g more than the Bold 9780.
The added touchscreen is a major novelty on the BlackBerry Bold Touch 9900. But the looks may fool you. It's a typical RIM messenger, conservative elegance and quality in a traditionally understated, professional design.
The front looks almost equally split between the 2.8" touchscreen and the keys (navigation controls and the QWERTY keyboard). The back was a surprise, something we weren't prepared for in a BlackBerry. The smooth edges are cut in comfortable holding shape and the soft rubbery finish gives good grip. It's the actual battery cover that splits our team's opinions.
The fiberglass plate did look a bit out of touch with a supposedly conservative, professional styling. Having the handset around for a good few days helped - it's obviously an acquired taste. But there are still members of our team who find it a lot more questionable than leather. It's an unusual combination. Some will appreciate the bold styling, while others might find it inconsistent with the business messenger image.
To cast all doubt aside, the BlackBerry Bold Touch 9900 gives us another great display. It's a 2.8" TFT capacitive touchscreen of VGA resolution. Crisp image at 286ppi and good sensitivity, the lack of haptic feedback is the only thing to complain about.
The sunlight legibility is excellent, to solidify the good impression recent BlackBerry smartphones have made. Viewing angles are about average - there's some contrast loss and color shifting when you look at it from extreme angles, but everything remains legible.
Now, to the next most important thing here - the QWERTY keyboard of the Bold Touch 9900 is very comfortable. The keys, it seems to us, are just the right bit softer than on previous Bold editions. This gives you speed without compromising the press feedback.
The keys are small but ergonomic and carefully sculpted for great tactility and usability - only users with very large hands may have trouble adapting. The only thing to warn against is one of the metal ridges dividing the rows of keys. The second one from the top does not fit firmly in place and bends when pushed. Nothing to stand in the way of comfortable typing but it raises concerns about the overall durability of the keyboard.
Many of the keys (not just the numbers) can be assigned speed dial. There is a dedicated currency symbol key and the usual command shortcuts: * locks the keypad and screen, while # toggles Silent mode on/off. Numbers share keys with some of the letters and you need to press the alt key to use them at times. The good thing is that whenever the context allows it, the switch is automatic.
There are four controls around a centrally placed trackpad: the typical BlackBerry combo of Call keys, with Menu and Back buttons. Although you now have a touchscreen at your disposal, the trackpad will be quite busy, giving you the needed accuracy in the browser or when handling text.
The 1230 mAh Li-Po battery is quoted at up to 307 hours of stand-by or 6 hours and 30 minutes of talk time. In real life, the battery lasted about two days of heavy usage. We were constantly connected to Wi-Fi and the 3G network, shooting the usual amount of stills and videos. There was quite a bit of video and music playback and web browsing too, with about 30 minutes of talks.
I'm a total noob when it comes to cctv thing. Right now i'm having difficulty trying to view a dvr/cctv via mobile (android/blackberry). Honestly I joined the forum because i don't know where else to go. I hope there's plenty of gurus here care to help me out.
So he bought this Angeleyes 16 channel H2.64 DVR along with 7 ip cameras. 3 vivotek IP8332 and 4 vivotek FD8134. He use his Linksys WRT54G router (already flashed with DD-WRT firmware) to connect to a cable modem.
The PC i use to set up all of the above are next to the router. And i think i might need to use it remotely from home (when i need to), so i asked my friend if it's ok if i set a remote access to it. He said to go ahead, so i set up a WOL to it and forwarded the necessary port in the router, and finally use RADMIN as ther controller software.
Now when i tried to view using my android and blackberry cellphone (port 34599), it just stuck with a black background. I use Vmeye and Meye software which is recomended by the DVR User Manual to view with android and blackberry devices. All of this test is using the DDNS address that i set on the router.
The next day i go to my friend's house and tried to access it locally by wifi with my mobile, but like yesterday, it just show blanks. I know i set the software settings right. I even change the Host as the local IP of th DVR and port on 34599.
As you can all see the system i set up above doesn't really need any DVR/NVR for it to work. The only reason the DVR is there is because IP cameras or the router won't have any way to display the camera feed/stream to his TV. Now it can also record videos from the cameras without having the computer turned on 24/7
After searching this forum for threads with the keyword "34599", i can not find any "solved" similar case. I read all those threads, and some comments are really tipical. "login with admin account", "account priviledge", "forward port 34599 in router", "what is your dvr model", "can you view locally with mobile", etc. Not really helping. There's one comment that really make sense i think. "reduce the stream's frame rate and the resolutions". I've done that but still no luck. Well i guess i can only blame the DVR unit then. Maybe it has some flaws in it, i don't know. The DVR is made in China, it's Angel Eyes 16 channel H264 hybrid DVR AE-D16S16ES. I don't know where he bought it, and i think he can't return and get a refund because it is a working product (just not with mobile viewing). And i know it should support and work with mobile view because the menu said so (there is this mobile view port submenu in the service menu...doh)
yes i have set the sub/extra channel and tried various fps/bandwidth/quality available in the DVR settings menu, and also in the IP camera config menu. even the lowest possible setting that make sense (6fps, standard quality, QCIF(176x144), h2.64/mpeg4 compression) does not work on blackberry. about the android, i just need to set it to lower fps from 15 to 8fps. the problem with blackberry still remain the same. buffering but no view, just black screen.
Only thing I can tell you is, use the mobile program that comes on the CD included with the unit. Do not download it from Google Play/App Store, try it with the one that comes with the unit. If you can not get it working with that, too bad. I have tried some of these cheap units, and sometimes the time I have to investo to get mobile viewing working is more than the cost of the unit.
If you can not get it working at all; since you have already forwarded all RTSP ports to each camera, I would just forget about MEye, and use IP Cam Viewer (you have free and paid version on Google Play). With it you might have some luck connecting to the unit, but if you can't, you will be able to view for sure the cameras on the RTSP streams (no playback, but live view is better than nothing).
I have successfuly utilized these cheap chinese dvrs with mobile viewing and can say it is an issue with the software made for the blackberries. Iphonr no issues, android no issues. Using the CD that come with them DVRs i realized refresh rate issues, screen size issues and buffering issues with different blackberries.
As for my experience the bold 9700 was the ONLY blackberry withOUT any issues to be able to view via mobile. 9780 had resulution issue can view full image but cant see program buttons, so yer stuck on cam 1. the torch had screen sliced in a way you cant see anything almost, and older bold 9000 will show you one frame and then entire program would freeze, forgot what issue was with the bold 9900, other blackberry models also failed for remote viewing. I say try the bold 9700 with all cameras set to substream qcif even if at 20 fps it worked with me.
