Write a flask application function need to read the file, the contents of the file containing the specified string (that is, there is a comparison of if key in Filecontent) the file content output to the page, the result error unicodedecodeerror, Consult Flask's documentation it seems that flask the default is UTF8 encoding, but now it's a mistake because the characters are UTF8 instead of ASCII. Finally solved the I'm a little bit of a filecontent decoding, written filecontent.decod

Once the Python installation is successful, the default encoding is ASCII, which is usually reported when non-ASCII code is present in the program.The way to do this is to change the Python default encoding to Uft-8Create a new file sitecustomize.py in the lib\site-packages in the Python installation file with the following code:#encoding =utf8Import SysReload (SYS)Sys.setdefaultencoding (' UTF8 ')Then restart Python to take effectReproduced Unicodedecodeerror: ' ASCII '

Vector sum excited linear prediction (vselp)Is a speech codingmethod used in several cellular standards. The vselp provided is ananalysis-by-synthesis coding technique and belongs to the class ofspeech coding known as CELP (Code Excited Linear Prediction ).[1] Variations of this codec have been used in several 2G cellular telephony standards, including is-54, is-136 (D-AMPS), GSM (Half Rate Speech) and iden. it was also used in the first version of

and easy to process in real time.2. 1.1.2 what is G.711 encoding?A:G.711 suggests a typical compression codec method using PCM waveform encoding to achieve higher speech quality, but the data compression rate is low.G.711 it is recommended to describe the μ-law (A-Law) compression of PCM, as shown in:The sampling rate is 8 kHz, and the 12-bit linear A/D is transformed into A digital signal. After the logarithm PCM, the data is compressed to 8 bit, an

I solved a problem with Ti codec last week. record it. The problem is that, on the omap4430 platform, the 720 p and 60framerate Avi cards are played in the JB version, and a lot of frames are lost when reading logs. In general, this situation is caused by insufficient CPU resources, however, I see that the CPU usage is not very high. After reading the code for half a day, I don't know what's going on. The reply from Ti is that the framerate they get

Recently, I have been studying the implementation of GIF on Android and have some experiences. Now I want to share it with you. At first, I saw the implementation of GIF on my mobile phone. It was an application of GIF kuaishou on the iPhone. I felt pretty good and wanted to implement it on Android. I checked it later. In the past, there was also a GIF kuaishou on Android, And the next one provided a good experience. Decompilation (sorry, you should use obfuscated compilation ). JavaAlgorithmB
