software using the signal format is the normal PAL format. 7. When making a video import, make sure that the video import software matches the audio input settings of the sound card. such as the software in the audio input for the mic, the audio line of the sound card mic mouth, sound card audio input set to mic. 8. If there is a failure to read the multimedia

and a connection state. Therefore, the above link layer frame may be broadcast data and may be the data after the connection. So there are two scenarios, one for the PDU in the broadcast channel and the other for the PDU in the data channel. We are mainly talking about the data frames in the data channel in the connection state, where the broadcast channel is briefly introduced. In the broadcast state, the PDU in the broadcast frame is shown in the following illustration, contains 2 bytes of he

essence is the same. The left channel is then in front, and the left channel is indicated with a low level. Since the clock polarity and channel control are the same, and this configuration is the default configuration of the codec chip, but also the first configuration of STM32. Then I configured the codec chip and the STM32 driver in this way, and also realized the function of Mic sound acquisition and playing through the horn. I certainly do not t

Centos/linux Fix SSH Connection slowOriginal: http://blog.csdn.net/doiido/article/details/43793391Connecting to a Linux server is now generally a way to connect remotely using SSH. Recently installed a server, found that Telnet is very fast, ping everything is normal, but SSH connection is very slow. After the online information query, there are a few reasons:1, the server sshd will go to DNS to find the hostname of the client IP access, if the DNS is not available or no related records, it will

I 've been learning Python program development for a long time. So I 'd like to share with you that you will surely have a lot of gains after reading this article. I hope this article will teach you more. When learning about Python program development, you may encounter Python program development problems. Here we will share with you. Due to my personal preference and familiarity with ubuntu, the following development process uses ubuntu regardless of the host environment or moblin platform. How

Since the standard ALSA is not used by default in Android, it uses Tinyalsa, so even command-line-based testing uses LIBTINYALSA.

3. Underlying behavior 3.1. underlying requirements EAP requires that the underlying layer have the following functions: [1] unreliable transmission. In EAP, the authenticator resends requests that have no response, so that EAP does not require the underlying layer to be reliable. Because EAP can define its own re-transmission behavior, when EAP runs on a reliable underlying layer, it can make both the underlying layer and the EAP layer have re-transmission.

Solve the problem of slow SSH connection in linuxCurrently, SSH remote connection is generally used to connect to a linux server. I recently installed a new server and found that telnet is fast, ping is normal, but SSH connection is slow. There are several reasons for the query:1. The SERVER's SSHD will go to the DNS to find the HOSTNAME of the accessed client ip address. If the DNS is unavailable or there is no relevant record, it will take some time.2.

For platform/machine domain, it is placed in the machine name directory, for example, neo1973_wm9753.c under the sound/soc/s3c24xx directory. The name is the same as the machine name and CODEC name. When defining the audio path of codec, you need to know this background. dapm is divided into the following parts in concept, Mixer-mixes several analog signals into a single analog signal.
