First go to open the bare metal driver key code BUTTON.C:1) key initialization---the choice of gpio function is external interrupt, the initialization of this hardware should be placed under the development of Linux where? A, in the Open function, B, in the initialization of the module. Choose one.The corresponding interrupt mode:Processing of interrupt numbersIn

Key hardware decoding and decryption and decoding Technologies In the previous article, we used ffmpeg to separate audio and video data in a multimedia container, but it is likely that the data cannot be correctly decoded. Why? Before decoding the data, you need to configure the decoder. A typical example is the combination of H264 + AAC, a popular "golden partner. This article describes how to parse

Power consumptionWe are now aware of:Binocular vision, single-point TOF, 3D tof,3d structured light, single-camera depth (Pdaf in the image to calculate depth).3D Tof is the point of multiple single-point tof formation.The pattern of structured light is more complex.Reflective is a big enemy of three-dimensional scanning, which produ

It is well known that Android has no clear guideline, although there is no strict specification to limit design and innovation, but it also leads to confusion on the design of Android apps in the marketplace. A typical example is the Options menu. Messy Menu The Android machine uses the hardware keys to exhale the menu, which, in a way that is implicit, is not predictive of what kind of menu the user can exhale, or even whether the menu can be paged

configuration, and audio object type, which are generally the configuration parameters required by the AAC decoder. This data also has the corresponding decoding function in the ffmpeg: Avpriv_aac_parse_header. In my project, I did not use this function, but I implemented it myself: typedef struct{INT Write_adts;int objecttype;int sample_rate_index; int channel_conf;} Adtscontext;Intaac_decode_extradata (adtscontext*adts,unsignedchar*pbuf,int BufSize) {intaot,aotext,samfreindex; inti,channelc

, channelconfig; unsigned char *p = pbuf; if (!adts | |!pbuf | | bufsizethe pbuf above is extradata. Next, use the Adtscontext data encoding to insert the ADTS header information in front of each AAC frame: int Aac_set_adts_head (Adtscontext *acfg, unsigned char *buf, int size) {unsigned char byte; if (Size the head is a fixed 7- byte length, so the 7 bytes can be vacated in advance for ADTS occupancy. through the above to H264 and AAC Extended Data processing, playing a var
