analyze the first frame of a TS file (SRS supports the TS file generated by HLS protocol) 1. PAT (Ignore) 2. PMT (Ignore) 3. First FRAME (PES Packet) Usually a frame of data is a PES package. A PES package can typically be split into multiple TS packages (it is also possible to split into only one TS package, that is, the PES package is less than 188 bytes in length). Pespacket==tspacket1+tspacket2+tspacket3+...+tspacketn PES Packet = = ts Packet1 + ts Packet2 + ts Packet3 + ... + TS Packe

~ First Look at a, an array is the array we want to maintain and query, but in fact we do not use the whole process of a array, you can think of it as a decoration! The C array is the center of attention and manipulation of our whole process. Let's take a look at the rules of the C array first, where C8 = C4+c6+c7+a8,c6 = C5+a6 ... Do not have to tangle how to do, we just know the approximate rules of the C array can be, it is easy to know that C8 re

Although the desktop version of AMD Kaveri APU has been on the market for quite some time, the mobile version has been quiet. Recently, a "amd Day Cat operating cooperative shop Product training" pptx file discovered Baidu Bar, with the training document exposure, AMD Kaveri APU Mobile version of more detailed information also with the exposure, although consumers of the new Kaveri Apu Mobile version of the concern is not high, But this exposure is indeed relatively sufficient material, let's se

Due to the needs of the project, the need to openwrt on the Ubus library to arm, Ubus is used for OPENWRT internal module communication between the library, similar to D-bus, but it is a lite version, specific to the OPENWRT official online to understand.

smart choices. This is why the framework ultimately dominates all aspects of our lives, even those that we are not programming. Note 1: Crossover compiler (English: Cross compiler) is a compiler that can produce an executable file for another system platform under one system platform. Cross-compiler is useful when the target system platform (the platform on which the application is developed) is difficult or not easy to compile.

. Paage address: page address. Because the page address is always aligned with bytes, its 9-bit low is always 0. Determine the page on which the read/write operation is performed. Read1 commandWhen we get a NAND flash Address src_addr, we can break down the column address and page address as follows: Column_addr = src_addr % 512; // column addressPage_address = (src_addr> 9); // page address You can also think that the a0 ~ Of a NAND flash Address ~ A7 is its column_addr, A9 ~ A25 is its page ad
