The acceptable encoding value is based on the restrictions that we can decode appropriately. Content

details the evaluation of several popular types of H. 264 decoder, including JM decoder, t264 decoder, x264 decoder, FFMPEG libavcodec, and Intel's IPP library. After evaluation, the author found that the fastest speed is Intel IPP, but intelIPP is a commercial software, and all other decoders belong to open-source projects. Therefore, the most suitable option is the FFMPEG with the second decoding speed, and its speed can fully meet the real-time playback requirements;
After the decoder is sel

In this example, the FastCGI program querystring. efcgi receives three parameters. The value of parameter X is ABC, and the value of Parameter Y is EF, the value of Parameter Z is % E4 % B8 % ad % E5 % 9B % BD (the decoded string is "China ).

When PROFILE_IDC equals 100, 110, 122, or 144, Constraint_set0_flag, Constraint_set1_flag, and constraint_set2_flag should be equal to 0.The value of LOG2_MAX_FRAME_NUM_MINUS4 should be in the range of 0-12 (including 0 and 12), this syntactic element is mainly for reading another syntactic element Frame_num service, Frame_num is one of the most important syntactic elements, it identifies the decoded order of the image to which it belongs.

then decode the Encodedjson to get the raw data and the json.loads () function we need to use. The loads method returns the original object, but some conversions of the data type are still occurring, with the ' ABC ' converted to the Unicode type in the example above. It is important to note that the dictionary type key in the JSON string must be double-quoted "" Json.loads () to parse correctly. The type conversions from JSON to Python are compared as follows:
Decodejson = Json.loads (encode
The following is an example of the Code for encryption and decryption in nodejs: {code...} How can php write the corresponding encryption and decryption code? It is required that the encrypted data such as Gpkr1WGBFhMvNdHr0eaBg can also be decrypted to nodejs. The following is an example of the Code for encryption and decryption of nodejs:
#! /Usr/bin/env node var crypto = require ('crypto'); // decrypt function decode (cryptkey, iv, secretdata) {var decipher = crypto. createDecipheriv ('aes-25

1. Next we will analyze the fill_audio_out_buffers () function
Static int fill_audio_out_buffers (void)
1.1 check the space of the audio driver to fill in the decoded audio data.
Bytes_to_write = mpctx-> audio_out-> get_space ();
If there is free space, Mplayer calls the ao-> play () function to fill in the buffer and play audio data.
The buffer size of the audio driver should be set properly. If the buffer size is too

1. register all container formats and CODEC: av_register_all ()
2. open the file: av_open_input_file ()
3. Extract stream information from the file: av_find_stream_info ()
4. Search for all the streams in codec_type_video format.
5. Find the corresponding decoder: avcodec_find_decoder ()
6. Enable the codec: avcodec_open ()
7. allocate memory for decoding frames: avcodec_alloc_frame ()
8. Continuously extract frame data from the code stream: av_read_frame ()
9. Dete

The macro block is the basic unit of decoding, and the decoder is decoded according to the predictive information and residual data . Functional Layering

player inserts an event into the queue to drive the entire decoding process. the workflow of the event scheduler is as follows:1. Check whether the queue is empty. If it is empty, wait for the event to be inserted.2. Get the first event in the queue3. Perform latency operations after calculating the delay time required by the event4. Remove the event from the queue and execute the eventThe event scheduler schedules tasks by repeating such a process continuously. In the specific code, the schedu
