Updated source of ipcamera for Nexus One Gingerbread (but targeted to 2.1-update1) #15

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Hello!

Please find attached an APK and the Eclipse workspace export for an updated 
WebCamera that "works" on the Nexus One / Gingerbread 2.3.3.

Needs more testing and someone to review the changes and merge them, but I just 
wanted to put the work so far out there in case someone is looking at this too.

I'm still not really satisfied with the latency / quality of the video (far 
from real-time), but it's fun ^_^

Changes:

-added dependency to isoparser library to enable accurate atoms parsing (and 
removed MediaDetect)
-removed some of the unnecessary data copies in StreamingKernel
-changed header offset from 32 to 44 (probably need to find a way to find the 
mdat automatically) - this is what makes it work with the Nexus One
-factored out code from the MainActivity to a new class Streamer to promote 
potential reuse in other app
-Change the behavior of enable/disable button slightly to enable Re-check all 
the time
-Updated version to 1.1
-added some onscreen stats (overall fps, Bps, overflow) for debugging
-updated flash player to JW 5.6 and configured player for zero-buffer, autoplay
-removed some unused commented out code
-added and cleaned up the logging
-added a proguard configuration
-tried to break down the FLV header configuration
-...

Thanks!

...also tested on the Nexus S... The quality is much, much better (it's pushing 
48K/s versus 8K/s on the Nexus one!).  Framerate is better too (15fps versus 
9fps) but latency is still too high.

with the aforementioned dynamic detection of the mdat in the stream, which 
should make it more resilient to encoder changes.

Great work! Are you interesting join in this proj?

Sure!  I'd love too, although I feel that you guys should review and submit my 
first few changes to make sure they're adapted to the style you want and 
actually cover your existing test cases.  

I actually made even more changes to the codebase; I've split aggressively the 
UI from the logic (with notifications and callbacks) so I could use it from a 
separate project. I've temporarily forked the code here (still in an half-done 
state), but my hope is we could just have everything back in the main 
repository:

https://github.com/rngadam/XinCheJian-GGHC/tree/master/android/eclipse-workspace
/WebCamera  

...main change will be this:

https://github.com/rngadam/XinCheJian-GGHC/blob/master/android/eclipse-workspace
/WebCamera/src/com/appdh/webcamera/StreamingServer.java

Also the other project I'm doing is also OpenSource but the license I selected 
is APL.  I was wondering if this project could be relicensed under LGPL so that 
there isn't an incompatibility between both?

Hi

I have installed your app on my Nexus One (Android 2.2.2) but I am having 
trouble successfully stream video to my Windows 7 PC running Firefox browser.

The browser gives me "Video not found or access denied: live.flv".
Any advice is very helpful.

I am able to run the app on the phone, but I am getting the following errors 
from logcat when I click "check" button.

Thanks,
David

I think it's probably because your system does not have the codec.  There's no 
requirement from the Android platform to have that codec provided so it's up to 
each individual manufacturer to offer that functionality or not.

The solution would be to modify the code to support a wider range of codecs.  I 
may look into this later.

Hi

I am running your app on Nexus One (Android 2.2.2).

The first errors (see below) I encounter is when the code runs this line: 
"mRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);" at initCamera() 
in MediaSource.java.

I am not sure why it won't set the videosource to Camera.

Thanks,
David

This one has clearer video than original but delay is much longer. Original 
one's is around 1-2 second but this one's is about 5 seconds.
