decoding the resynchronization, when the decoder decodes to IDR image, immediately empty the reference frame queue, the decoded data are all exported or discarded, re-lookup parameter set, start a new sequence. in this way, if there is a major error in the previous sequence, you can get a chance to resynchronize here. The image after the IDR image will never be decoded using data from the image before IDR.
First, FFmpeg decoding process: 1, register all container formats and Codec:avcodec_register_all (), 2, find the corresponding decoder: Avcodec_find_decoder (av_codec_id_ MJPEG); 3, allocating codec parameter data structure AVCODEC_ALLOC_CONTEXT3 (Avcodec *codec); 4, for partial codecs the data structures that are allocated in the previous step are initialized because some parameters are not valid in the video stream; 5, Open codec: Avcodec_open2 (Avcodeccontext *ctx, Avcodec *codec, NULL);

It is also a bunch of antidebugger... and finally jumps to the real OEP of the program to deal with such shells.The method is to first find the OEP and then fix the IAT
When the shell jumps to OEP, it is generally a cross-segment jump. There are many

We'll then decode the Encodedjson, get the raw data, and use the Json.loads () function. The loads method returns the original object, but some data types are still transformed, and in the example ' ABC ' is converted to Unicode type. It is important to note that the key of the dictionary type in the JSON string must be in double quotes "" Json.loads () to parse correctly. The type conversion from JSON to Python is as follows:
Decodejson = Json.loads (e

Optimization of iOS image loading speed limit-FastImageCache resolution
FastImageCache is an open-source library developed by the Path team to accelerate image loading and rendering, so that the image-based list slides more smoothly to see how it works.Optimization points
