我使用Android的MediaCodec API编写了H264流编码器.我在大约十个不同处理器的不同设备上进行了测试,除了Snapdragon 800驱动的设备(谷歌Nexus 5和索尼Xperia Z1)之外,它在所有设备上都有效.在这些设备上,我得到了SPS和PPS以及第一个Keyframe,但之后mEncoder.dequeueOutputBuffer(mBufferInfo,
isVideoOver = putBufferToMediaCodec(mediaExtractor, videoDecoder); } // 返回一个被成功解码的buffer的 index 或者是一个信息 同时更新 videoBufferInfo 的数据 int outputBufferIndex = videoDecoder.dequeueOutputBuffer(videoBufferInfo, TIMEOUT_USEC); switch (outputBufferIndex) { case MediaCodec.INFO_OUTPUT...
3. 之后可以调用 MediaCodec.start() 方法启动Codec,Codec会转入 Executing 状态,start后Codec立即进入 Flushed 子状态,此时的Codec拥有所有的input and output buffers,Client无法操作这些buffers; 4. 一旦第一个input buffer 出队列,也即Client通过调用 MediaCodec.dequeueInputBuffer(...)请求得到了一个有效的input buf...
