Can you already capture an image? It would probably be worth starting with this. The process of hardware encoding to jpeg will need to be done later and it is quite simple.

Textured Cube的例子帧率有多少?

The frame rate depends on the size of the cube and varies from 35 to 11 fps. At the moment when the height of the cube is equal to half the height of the screen, we have 25 fps. Source code with frame rate output to the terminal here: TinyGl Textured Cube Demo

How about GT911 capacitive touchscreen supports? Thanks.

Sorry, not planned. In the near future, an I2C(TWI) driver and examples of working with TS NS2009, RTC PCF8563, FM Radio RDA5807, HDMI IT66121 will be added.

I want to connect PR2000K to the F1C100S to capture the AHD-video. I found interesting information on the link, but I can not download it. I ask the help of friends on the forum. Who can download this file for me? I would be very grateful.

Example of using USB-Ethernet adapter and lwIP-library.
Adapters based on the RTL8152B chip are supported. The driver from u-boot was taken as the base. This program runs on bare metal and depends on the lwIP TCP/IP stack. In this example, the available services are ping, iperf, and http server. At the same time, iperf demonstrated the use of a bandwidth of more than 90Mbits/sec.

Now I have too little time. Because of the war, I had to leave my city and now I settle down with my family in a new place. At the moment I have an MPEG1/2 decoder implementation. I'll try to put it out as soon as possible in my repository: https://github.com/minilogic/f1c_nonos

Small modification of the previous demo.
Converting tile-based data is done by the mb32dec function. Color conversion - hardware by debe-module.
Decoding time 3-4ms. MB32 transformation 8-9mS. As a result: fps = 1 / (0.004 + 0.009) = 76

Do you have the document about this feature? For example: Allwinner user manual...?

This project is based on CEDRUS sources.
JPEG decoding is fast. YUV2RGB converting in the first sources is slow (~60mS), so in the mjpeg demo I did a table conversion (~24mS).
