client.client.目前的硬件转码使用MediaCo-虎哥说创业

Here are my steps: Open demo app (release-v2 branch) Clear Dash -> HD (MP4, H264) I have the following result (see video) Configuration: — Android Studio 2021.2.1 Patch 1 — Emulator: Pixel 2 API 30, Android 11 Google Play | arm64. And yes, with this specific emulator (API 30), I can always reproduce the error, but not in other API. INFO_OUTPUT_FORMAT_CHANGED. The following examples show how to use android.media.MediaCodec #INFO_OUTPUT_FORMAT_CHANGED . You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. You may check out the related API usage on the sidebar. Example 1.. Another new class introduced in Jelly Bean is the android.media.MediaExtractor. It is pretty clear what it is all about, extract the metadata from your media and a lot more..2022. 8. 11.· MediaCodec的编解码流程. MediaCodec采用异步方式处理数据，并且使用了一组输入输出buffer（ByteBuffer）。

. 1.使用者从MediaCodec请求一个空的输入buffer（ByteBuffer），填充满数据后将它传递给MediaCodec处理。. 2.MediaCodec处理完这些数据并将处理结果输出至一个空的输出buffer. GitHub Gist: instantly share code, notes, and snippets.. 2013. 4. 21.· MediaCodec class can be used to access low-level media codec, … After a successful call to start() the client “owns” neither input nor output buffers, subsequent calls to dequeueInputBuffer(long) and dequeueOutputBuffer(MediaCodec.BufferInfo, long) then transfer ownership from the codec to the client.private void drainAudio(boolean endOfStream) { // LogUtils.v(String.format(“drainAudio %b”, endOfStream)); ByteBuffer[] inputBuffers = mEncoder.getInputBuffers(); int bufferIndex = mEncoder.dequeueInputBuffer(-1); // wait indefinitely if (bufferIndex >= 0) { ByteBuffer inputBuffer = inputBuffers[bufferIndex]; inputBuffer.clear(); int len = mAudioRecord.read(inputBuffer, SAMPLES_PER_FRAME * 2); // read blocking long ptsUs = System.nanoTime() / 1000; if (endOfStream) { mEncoder …. 2020. 3. 7.· MediaCodec class can be used to access low-level media codecs, i.e. encoder/decoder components. It is part of the Android low-level multimedia support infrastructure (normally used together with MediaExtractor, MediaSync, MediaMuxer, MediaCrypto, MediaDrm, Image, Surface, and AudioTrack.). In broad terms, a codec processes input data to generate. 2013. 4. 21.· MediaCodec class can be used to access low-level media codec, … After a successful call to start() the client “owns” neither input nor output buffers, subsequent calls to dequeueInputBuffer(long) and dequeueOutputBuffer(MediaCodec.BufferInfo, long) then transfer ownership from the codec to the client.2022. 8. 13.· MediaCodec+MediaMuxer： MediaCodec 与 MediaMuxer 结合使用同样能够实现录制的功能。

MediaCodec 是 Android 提供的编解码类，MediaMuxer 则是复用类(生成视频文件)。从易用性的角度上来说肯定不如 MediaRecorder，但是允许我们进行更加灵活的操作，比如需要给录制的视频添加水印等各种效果。. The MediaCodecclass first became available in Android 4.1 (API 16). It was added to allow direct access to the media As such, it provides a rather “raw” interface. sources, only the former is public. In Android 4.3 (API 18), MediaCodecwas expanded to include a way to provide input through a Surface(via the. 2022. 8. 14.· 最近公司要求提供一个支持Android硬件转码的底层库，所以自己从头去看了MediaCodec相关的知识，费了老大的劲终于完成了。
