Cool [Q] Screen recording with LG P880

I am trying to record activities on my phone screen with Screencast Video Recorder but the video recorded has only LG logo in it.

https://play.google.com/store/apps/d...screencastfree

Is there a way to overcome this problem?

Note: My phone is rooted with EU Open 10H.

you cant screencast/record sreen this way with the 4X
short story:
4X has an nVidia tegra 3 cpu
every screencast app available requires the NEON feature
Tegra 3 doesnt support NEON
nVidias fault...

are you sure? Check wikipedia or any other tool. Even mx player and vidcon use neon codec. I think it's sofware's fault. It said not to be supported on nexus, tegra 2/3.

have you read before download?
"Does not work on Galaxy Nexus or Tegra 2/3". Maybe an alternative available. How about giving a overlay of chainfire 3d before installing this?

I have read Screencast information before downloading and I'm aware that it says it does not support Tegra3.

My question was about the "LG Logo" being recorded.

Screencast seems to be working fine, it does not complain about the Tegra3 chip while recording, but when you watch the video recorded, what you see is an LG logo with "LG" text.

I tried another application (whose name I can not remember), the same thing, LG logo.

Is there any other application you know which can record like Screencast and does not require the NEON feature? (whatever it is...)

Can anybody with any custom ROM installed try to record with Screencast?

You didnt see the problem.

the NEON i talked about is a feature enabled in the cpu

All known to me screen recording apps uses this feature to request a raw copy of the data that goes to the screen, which is then saved as something you can use later

When nVidia created Tegra 2 - and later Tegra 3 - they chose not to implement this feature - for reasons unknown to me.

Instead the kernel will give it a copy of the initial boot picture. This cannot be changed

Sorry if the language was hard to understand.

Oh; i forgot to mention that certain apps - as cpu control apps - mistakenly reports NEON as enabled. This is wrong

Where on earth do you get your bull****? Lol Tegra 2 doesn't have NEON, but Tegra 3 does support NEON. Also, where did you get the idea that some apps wrongly reported Tegra 3 having NEON support? Do your checks before informing others of something.

Wikipedia also says as much.

I never read any wiki
This was based on experience

And if NEON was there; why would the kernel fail to retrieve and give the correct imagedata to the screen?
I tell you; that if NEON is there, and it might aswell be, then nVidia made it so bad that i would say you can hyperthread a old amd phenom cpu better
No offence amd users

Plenty of apps out there use NEON, and guess what? They work well on the Tegra 3. Furthermore, the GNex does not support Screencast. By your logic, the GNex (an OMAP4460) does not support NEON?

By experience? Your experience in this case is hardly reliable. Oh gosh, I calculated g to be equal to -3 metres per second per second using my heartbeat and a feather. All the people over at NASA must be wrong. g is definitely nothing close to 9.8 metres per second per second.

And about NEON implementation: you can't have lousy implementation. You either support it or you don't. End of story.
