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'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.

I am using Firestore database in Android Application. If any more information is required, Please let me know


public void onFilter(Filters filters) {

        if (filters.hasCategory()) {
            query = query.whereEqualTo("postcategory", filters.getCategory());

        // Limit items
        query = query.limit(5);
