res_xxxxx.so, for example res_musiconhold.soCodec moduleA kind of codec, is a kind of audio or video codec module. Typically used to compress media to reduce bandwidth consumption.Codec modules are named codec_xxxxx.so, such as codec_alaw.so, codec_ulaw.soThe codec module provides the encoding and decoding algorithm of the media stream. Asterisk uses a codec module when receiving and transmitting media (audio and video). This module also accomplishes the conversion between different coding algo

With regard to the annular flow buffer, see the Reference link section. 2, sound compression is a difficult choice of steps, the default DirectSound can only play and record the PCM format (WAV) audio data, but this sound format is particularly large. Commonly used sound compression format has h.7231,gsm,amr,h.711 and so on, all kinds of compression algorithms have their own rate and

security:(1) Before installing Oracle Server, create a database administrator group (DBA) and assign the user IDs of the root and Oracle software owner to this group. Only 710 of the programs that DBA can execute are permitted. During the installation process, the SQL * DBA system permission command is automatically assigned to the DBA group.(2) allow some Unix users to access the Oracle server system with restrictions, add an Oracle group of authorized user groups, and ensure that the Oracle g

The SHELL problem encountered today-general Linux technology-Linux programming and kernel information. The following is a detailed description. In linux, how to use a script to obtain the permissions of a file is to convert the permissions in the form of-rwx -- x to 711. Remember to use chmod 711 for recovery. At the beginning, I used ls-l to get the data, and then printed the first column with awk. I wa
