以下代码适用于API 21及更高版本。但是,当我在21以下运行时,没有数据出现在TextureView上。
我对MediaCodec的配置:
MediaFormat format = MediaFormat.createVideoFormat(MediaFormat.MIMETYPE_VIDEO_AVC, 1920, 1080);
format.setByteBuffer("csd-0", ByteBuffer.allocate(100));
format.setInteger(MediaFormat.KEY_MAX_INPUT_SIZE, 100000);
try {
m_codec = MediaCodec.createDecoderByType(MediaFormat.MIMETYPE_VIDEO_AVC);
m_codec.configure(format, new Surface(m_surface.getSurfaceTexture()), null, 0);
m_codec.start();
} catch (Exception e) {
e.printStackTrace();
}
解码部分:
int inputIndex = m_codec.dequeueInputBuffer(-1);
if (inputIndex >= 0) {
ByteBuffer buffer;
MediaCodec.BufferInfo info = new MediaCodec.BufferInfo();
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
buffer = m_codec.getInputBuffer(inputIndex);
buffer.clear();
}
else {
buffer=m_codec.getInputBuffers()[inputIndex];
buffer.put(videoBuffer,0,info.size);
}
if (buffer != null) {
buffer.put(videoBuffer, info.offset,videoBuffer.length);
m_codec.queueInputBuffer(inputIndex, 0, videoBuffer.length, 0, 0);
}
}
MediaCodec.BufferInfo info = new MediaCodec.BufferInfo();
int outputIndex = m_codec.dequeueOutputBuffer(info, 0);
if (outputIndex >= 0) {
m_codec.releaseOutputBuffer(outputIndex, true);
}
我得到了解决方案,当我删除线下,现在它正在工作
format.setByteBuffer("csd-0", ByteBuffer.allocate(100));
