Decoding with OMX.SEC.vp8.dec and OMX.google.vpx.decoder in Samsung Galaxy Y Duos

manpreet Best Answer 2 years ago

I am trying to decode a VP8 encoded stream with OMX.SEC.vp8.dec and OMX.google.vpx.decoder in Samsung Galaxy Y Duos. I am configuring MediaCodec with surface and it shows the following error in the log. I am not sure if there are any MediaCodec or MediaFormat settings required prior to configuring MediaCodec which are specific to VP8/VP9 codec. The mimeType I am using is video/x-vnd.on2.vp8

Edit (after fadden's reply): Code

int colorFormat = 0;
int frm_width  = 640;
int frm_height = 360;
int frm_format_choice = 0;
String mimeType = "video/x-vnd.on2.vp8";
String[] types = info.getSupportedTypes();
int numCodecs = MediaCodecList.getCodecCount();
MediaCodec mediaCodec = null;
MediaFormat mediaFormat = null;

public int  decode_frame() {
    MediaCodec.BufferInfo bufferInfo = new MediaCodec.BufferInfo();

    for (int i = 0; i < numCodecs && codecInfo == null; i++) {
        MediaCodecInfo info = MediaCodecList.getCodecInfoAt(i);
        if (info.isEncoder()) {
            continue;
        }
        String[] types = info.getSupportedTypes();

        for (int j = 0; j < types.length && !found; j++) {  
            if (types[j].equals(mimeType)) {
                found = true;
