Large File Support in Andorid

+1 vote
415 views

I'm trying to random access some bytes in a Huge File(>4GB) in Android platform in a C code. However, fseek & ftell have the int limitations. Googling gave the options of fseeko & ftello with the compiler flag -D_FILE_OFFSET_BITS=64, but that it doesnt seem to work. So is it possible and is there a solution for the problem.

Try the system call level APIs in NDK : lseek64 takes an off64_t.Or the SDK API is java.io.RandomAccessFile.seek which takes a Java long that's 64 bits.

I have an Open-MAX component which can decoder AVC/H264 streams. The component works fine for .MP4 clips and I am able to play without issues. Now when I switch to .ts clips (which are .h264/AVC with AAC audio (because android only support that)), I see that the input buffer size is never sufficient to push the data in to the hardware.

By default I have a buffer size of 32kb which is later increased to 64kb (by SetParameter Call). I see the failure in this case.

Then I change the buffer size to 256 kb then this size is retained and not changed by setParameter call. I see the above issue with 256kb input buffer size. Even in this case I see the failure (attached log below).

I get the following error :

I/ATSParser( 2000): resizing buffer to 262144 bytes 
I/ATSParser( 2000): resizing buffer to 327680 bytes 
E/OMXCodec( 2000): [OMX.BCM.Video.decoder] Codec's input buffers are too small to accomodate buffer read from source (info->mSize = 262144, srcLength = 269076) 
E/MediaPlayer( 3598): error (1, -**********) 
E/MediaPlayer( 3598): Error (1,-**********) 
D/VideoView( 3598): Error: 1,-********** 

Any input -

I am working on a android based device used for biometrics capture (iris, fingerprint, face) and some amount of local matching.

We have platform that has 2GB of memory and we want to let Android apps have large enough memory heap.

I know one can build my custom rom with build.prop with custom dalvik.vm.heapgrowthlimit, dalvik.vm.heapsize , in our experiments setting this limit to be more than 1GB causes board boot failures.

Has anybody else experimented with increasing heap size for Android application, on custom rom? I am also looking at increasing cursor window memory size as some of the biometric data is stored in sqlite
database.

Anybody else tried to wrangle Android platform to do more memory intensive applications any other places I should be looking to alter things?
