In the previous blog, we mentioned the control flow related to stagefright, analyzed the creation of MediaExtractor, AwesomePlayer, StagefrightPlayer, and OMXCodec In the android architecture, and the creation of OMXNodinstance at the underlying layer. This article analyzes the architecture of the underlying plug-in library and decoder component of OMX and how to create our own OMX P

The I ' m using the dev build, zeranoe.com which has OpenH264 and libx264 in it. How can I choose between this two decoders to compare the decoding speed? avcodec_find_decoder (avcodecid.av_codec_id_h264); Only gives me the name "H264" but which decoder is it?

In network transport and file operations, if the amount of data is large and needs to be divided into smaller, fast, it may appear that at the end of a block of data there is a mismatched high surrogate, and its matching low surrogate is in the next chunk.This time using the encoding GetBytes method to deal with the more troublesome, we directly use the encoder processing.Encoder can encode a set of characters into a sequence of bytes. Instead, decoder

In this way, different decoding methods can be automatically identified by the sub-firmware after 4.0 compilation.
For more than 4.0 of them, we try to automatically decode the QR code.
In versions lower than 4.0, we tried to call the camera function and then decode the captured image.

This document records the FFmpeg-based video decoder on another Android platform. Unlike the decoder documented in the previous article, the decoder documented in this article no longer uses class libraries such as libavcodec.so, libavformat.so, and only uses a class library--libffmpeg.so. The source code for the video decode
In the previous section, we have implemented QR code scanning, which we use bounds and corners of metadata to achieve a visual scanning effect.Bounds defines a rectangle that contains a two-D code image, and corners defines the actual coordinates of the two-dimensional code image:The bounds and corners are the same when the camera and the QR code picture are completely aligned. But in general, it is almost
