Encoder Enhancements
--------------------------------
1) slice-parallel mode gets a significant boost in performance,
Particularly in low-latency mode.
2) x265 now officially supported on VS2017.
3 x265 now supports all depths from mono0 to mono16 for y4m format.
API Changes

Requirement: The Android side puts a video stream that is playing on the webcam and intercepts it to save it as a MP4 (the recording is started when the video button is pressed).
Implementation: FFmpeg + x264 + sdl;
H264 Bare stream Packaging into MP4, there are a lot of articles on the Internet, FFmpeg also has a muxing example, the general process is the same, referring to FFmpeg muxing.c can write one. I am here to write about the problems I encountered in this process, these problems bothere

1. Get data ffmpeg read the H264 data in MP4, and do not directly get Nalu, the file does not store 0x00000001 separator. The following figure is the data in Packet.data As you can see from the diagram, there is no delimiter (0x00000001) at the beginning of the data in packet, nor is it 0x65, 0x67, 0x68, 0x41, and so on, so it is certain that this is not a standard Nalu. In fact, the first 4 characters 0x000032ce represents the length of the N

memory space.
Conclusion: do not modify the string type in a large loop.
See my buddyCode:
String [] filemobile1 = file. readalltext (cb_file1.selecteditem.tostring (), encoding. getencoding ("gb2312 ")). split (New String [] {"\ r \ n"}, stringsplitoptions. removeemptyentries); string [] filemobile2 = file. readalltext (cb_file2.selecteditem.tostring (), encoding. getencoding ("gb2312 ")). split (New String [] {"\ r \ n"}, stringsplitoptions. removeemptyentries); dictionary
