h 265 encoder

close to an envelope. That is to say, the "best preset" is not affected by the video content (of course, there is still a little bit, but the degree is not big ). This report uses the "bus" test video sequence experiment results. Summary This report uses four methods to analyze the x264 option:1. Use convex hull to analyze the optimal option. 2. Use the "color Cloud Chart" to analyze the option. This method is simple and intuitive, but cannot be accurately quantified. 3. Use Lambda paramete

Refer to the following article:http://blog.csdn.net/a992036795/article/details/54286654First, prefaceAs I said in the previous article, I used libx264 to encode video h264 very inefficiently, because libx264 uses soft coding. So I searched online to learn that using the system API can hard code video, thereby reducing the pressure on the CPU, to improve the efficiency of the role. I wrote a demo and tried it, and it was obvious that efficiency was improved.second, the idea1. Core class Med

the LED lights running water or flashing. I would like to ask: 1. STM32 for GPIO operations generally use library functions, then how to make a certain port reverse? How to make a mouth shift water? Please write a demo code. 2. I see an example of a pc6port led flashing code such as the following, do not know what it means? Is it a counter-operation? Why read a bit first?Gpio_writebit (GPIOC, Gpio_pin_6, (bitaction) (1-gpio_readoutputdatabit (GPIOC, Gpio_pin_6))); 3. Interrupt vector table is n

Incremental rotary encoder Output the Pulse Sequence Based on the Rotation Variation of the axis. You can use other counters to calculate the number of output pulses and use the counters to check the rotation volume. You can append a circuit to generate 2 times of a periodic signal, 4 times the number of pulses, and provide the resolution of current. Selection criteria 1 incremental or absolute 2.

This week, I made a computer mouse's encoder module and spent a whole week.This process makes us laugh and cry. We plan to use the CH3 and methane channels of tim3 to collect the PWM of the Left motor for speed measurement and ranging, and use the CH2 and cosine of tim4 to test the right motor.WriteCodeFirst, we did the left motor first. It went to Friday, and we found that the CH3 and 4th channels of the general timer could not be used for PWM input.

1, open the encoder, set the code frame parameters Profile@level, according to the needs of the direct choice of 720p or 1080p, etc. on the line. 2, the following encoding type (Encoding type) is more important. First is single, which is the simplest type of encoding, with the advantage of being fast, but with the same compression rate per frame, which can be wasteful or inadequate. In general, this is enough, choose Single Pass mode, the followin

Record Cool The settings in the Encoder window will directly affect the video's quality, sound and bitrate. Video size: If you want to record HD video, just select "HD Mode", one of the "original quality" is the best, but the resulting file and network code flow will be the largest, "super clear quality" slightly less clarity, but a small half of the file, fluency will also be much higher, you can choose 1/2 size, will be recorded in half the size;
