Need help with building

Hi,

Thanks for the uploading the project as open source. I was trying to build ffmpeg using NDK version 9. I referred you blog, http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/.

After following all the steps as mentioned in the blog I was able to build the ffmpeg with no issues. However, while building the jni it throws following error:
Android NDK: jni/Android.mk: Cannot find module with tag 'ffmpeg-2.0.1/android/arm' in import path
Android NDK: Are you sure your NDK_MODULE_PATH variable is properly defined ?
Android NDK: The following directories were searched:
Android NDK:
jni/Android.mk:11: *** Android NDK: Aborting. . Stop.

I have copied the ffmpeg-2.0.1 in $NDK/source folder and as well in the tutorial_project/jni. Even then the error pops up.

Need some help resolving this.

Thanks,
Vinay

Jni build error

Hi
I'm try to these tutorial. I built ffmpeg without problems.
But when i build jni with ndk-build, under error occured.

ndk-build
Android NDK: /Users/dhko/android/android-ndk-r9d/sources/ffmpeg-2.0.1/android/arm/Android.mk:tutorial01: LOCAL_MODULE_FILENAME should not include file extensions
Android NDK: ERROR:/Users/dhko/android/android-ndk-r9d/sources/ffmpeg-2.0.1/android/arm/Android.mk:tutorial01: LOCAL_SRC_FILES should point to a file ending with ".so"
Android NDK: The following file is unsupported: tutorial01.c
/Users/dhko/android/android-ndk-r9d/build/core/prebuilt-library.mk:36: *** Android NDK: Aborting . Stop.

My Environment

Scrambled Image with certain screen resolutions

I ran tutorial02 on a HTC one with a screen resolution of 1080 x 1920 pixels. Now I get the behaviour as shown in the screenshot:

The image is scrambled, the lines are somehow shifted towards the left. The Video works fine on other devices. I think the problem is that, the frameRGBA->linesize does not match with the windowBuffer.stride. In my case the first one is 1080 and the latter one 1088. Do you have an Idea what may be the error?

Thanks for your help.
