FFMPEG (ii)-Universal multiplexer
One: Technical points
As mentioned in the previous article, the reuse structure of the MP4 type differs from other types, such as mp4,mov,flv, where the H264 data does not contain descriptive information such as SPS,PPS, to reduce overhead,
The same is true for AAC data, which requires converting the previous 7-byte Adts header to a two-byte frame length.
FFmpeg provides something called the filter filters to do this.

[Problem description]
Dilhao has a total of N textbooks, each of which has a difficulty value. Each time he answers a question, he will pick two textbooks for reference. If the difficulty of the two books is different, the more complicated the questions that result from dilhao, that is,The complexity of a question equals the absolute value of the difficulty difference between the two books.
This is the turn of ldxxx. He wants to ask about the problem by using the m book. dilhao wa

We can see this question, and we can think of one-dimensional difference at a glance.
However, this complexity is O (NQ), and obviously t
So how to optimize it?
We will find that in the difference ~ Within the L-1 range
The values added by the difference are the same as the X-axis, and the y-axis increases progressively.
The abscissa and ordinate values of the reduced values increase with 1 as the tolerances.
Then, we can divide th

First, let's talk about the differences between E1 and T1:
E1 is widely used in China and Europe.
T1 is widely used in the United States and Japan.
E1 = 2.048 Mbit/s = 32 * 8bit * 8000
T1 = 1.544 Mbit/s = (24*(7 + 1) + 1) * 8000

2. Introduction to T1
The T1 digital stream consists of 24 64-kbpsChannelS that areMultiplexed. (The standardized 64 Kbps channel is based onBandwidthRequired for a voice conversation .)
In the T1 system, voice or other analog signals are sampled 8,000 times a second and each sample is digitized into an 8-bit word. with 24 channels being digitize

B1 also along the B0 direction with Rameau frequency rotation:
For the sake of simplification, it is envisaged that there is a rotating reference system in which the rotational frequency of the reference system is also the Rameau frequency, and the B1 is stationary relative to the reference system. In the role of the B1, M0 will be rotated B1 for the rotation axis, after a very short time, M0 rotated 90 degrees, fell on the X-y plane.
This B1 is called a 90-degree pulse, at which point the b1
T1: Number theory + high precision (water ~)
According to the question, the bigger the number of division, the better (in the range of 0 ~ 9)
So we only need to use high-precision division and then simulate it.
