But i got an error: format: {frame-rate=15, height

The MediaCodec is tied to a OpenGL Texture (SurfaceTexture). In general everything works fine. But the Decoder appears to buffer frames. If I put a frame in the decoder it is not rendered immediately to the texture. After I put 2-3 frames more in the decoder the first frame is rendered to the texture. I'm implementing against Android 4.4.4. private static final int INFINITE_TIMEOUT = -1; private static

I am referring to this excellent example of how to encode the preview frames of the camera directly into an mp4 file: http://bigflake.com/mediacodec/CameraToMpegTest.java.txt I have adopted the code in the way that I also would like to render the preview image on the screen. Therefore I got something like a GLTextureView with its own EGLContext. This Context is then used as shared EGLContext when I create the EGLContext for the encoder rendering: mEGLContext = EGL14.eglCreateContext(mEGLDisplay, configs[0], sharedContext == null ? EGL14.EGL_NO_CONTEXT : sharedContext, attrib_list, 0); In my

I have an app that manages its own GLSurfaceView and now I want to use Android 4.3's new MediaCodec feature that takes a Surface as input. In all the examples I've seen, the Surface is created using MediaCodec.createInputSurface(), then the GL context is created for this Surface. This feels monolithic and incredibly disruptive to retrofit into a code base that is already stable. Is it possible to use MediaCodec.configure(format, a_predefined_Surface, null, MediaCodec.CONFIGURE_FLAG_ENCODE) instead? This allows me to use MediaCodec in a plug-and-play and on-demand way. The fact that MediaCodec

I'm writing an app that records screen capture and audio using MediaCodec. I use MediaMuxer to mux video and audio to create mp4 file. I successfuly managed to write video and audio separately, however when I try muxing them together live, the result is unexpected. Either audio is played without video, or video is played right after audio. My guess is that I'm doing something wrong with timestamps, but I can't figure out what exactly. I already looked at those examples: https://github.com/OnlyInAmerica/HWEncoderExperiments/tree/audiotest/HWEncoderExperiments/src/main/java/net/openwatch

I am using Google's Open Source Example: Grafika . I am using it's ContinuousCaptureActivity.java The CircularBuffer's Implementation is demonstrated in this Activity, but there is no audio included in the resultant Video file. I want to add the Audio Recording functionality within this Activity and add the recorded Audio into the Video in the same CircularBuffered Fashion. For achieving this i have explored the MediaCodec Library, which was introduced in 4.3+ versions. I have also used MediaMuxer to capture Video and Audio Streams and Muxed them into a single Video. But, I am not sure about

I'm modifying an Android Framework example to package the elementary AAC streams produced by MediaCodec into a standalone .mp4 file. I'm using a single MediaMuxer instance containing one AAC track generated by a MediaCodec instance. However I always eventually get an error message on a call to mMediaMuxer.writeSampleData(trackIndex, encodedData, bufferInfo) : E/MPEG4Writer﹕timestampUs 0 < lastTimestampUs XXXXX for Audio track When I queue the raw input data in mCodec.queueInputBuffer(...) I provide 0 as the timestamp value per the Framework Example (I've also tried using monotonically

项目地址 https://github.com/979451341/Myijkplayer 前段时候我觉得FFmpeg做个视频播放器好难，虽然播放上没问题，但暂停还有通过拖动进度条来设置播放进度，这些都即便做得到，可以那个延缓。。。。。 现在学习一下目前移动端最知名的视频播放器的框架ijkplayer，这个框架他是基于FFmpeg、SDL、还有安卓原生API MediaCodec之类的。他是没有播放界面的，这个需要我们去做，所以这个里我就做个基于ijkplayer的视频播放器，随便浅显的说一下ijkplayer的源码，关于ijkplayer的源码以后会专门出一篇博客说一下。 1.首先了解一下ijkplayer咋用 我这里引入ijkplayer是通过添加依赖 implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8' implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8' implementation 'tv.danmaku.ijk.media:ijkplayer-armv5:0.8.8' implementation 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8' implementation 'tv.danmaku
