错误以及崩溃已修改，其中最大问题是DEFAULT_BUFF_MAX_SIZE ，默认读取一个NALU可能超过350000（我自测的mp4视频文件，可能还更大）

1.startcode有两种，这是包开始

    0x00 0x00 0x01
2.接下来就是上面的NALU头
uiForbidden规范为0，下面都不做解释
《A》可能是整装：
    头结构只有一个NALU头结构体比如0x67就是
    二进制0              1 1         0 0 1 1 1
    uiForbidden      uiNRI        uiType
    代表重要性值为3(非常重要) 类型为7(SPS序列参数集)
《B》可能是分片：
    头结构第一个FU indicator 结构体比如0x5c就是
    二进制0              1 0         1 1 1 0 0
    uiForbidden      uiNRI        uiType
    代表重要性值为2(重要) 类型为28(FU-A)
     头结构第二个就是FU      header结构体

3.编译脚本

makefile

如下INC1、INC2、LIB1、LIB2变量都是自己安装jthread以及jrtp相对应的头文件和库（一定要对应的，特别是头文件）

安装jthread以及jrtp参考我的另外一篇

.PHONY: $(PHONY)

假如要调试加入gdb的话，如下：

src-list    :=  $(filter %.cpp,$(shell ls $(M)))
obj-list    :=  $(patsubst %.cpp,%.o,$(src-list))
dep-list    :=  $(patsubst %.cpp,.%.d,$(src-list))

src-list    :=  $(addprefix $(M)/,$(src-list))
obj-list    :=  $(addprefix $(O)/,$(obj-list))
dep-list    :=  $(addprefix $(M)/,$(dep-list))

PHONY       :=
target      :=  $(O)/built-in.o

CC=g++

PHONY   += __build
__build: $(target)


$(target): $(obj-list)
    $(CC) $^ -o $@ -std=c++11 $(INC1) $(INC2) $(LIB1) $(L1) $(LIB2) $(L2) -g

# 生成依赖文件.d
$(dep-list):  $(M)/.%.d: $(M)/%.cpp
    $(CC) -MM $< > $@ $(INC1) $(INC2) -g
    @echo "$(O)/`cat $@`\n\t\$$(CC) -c -o \$$@ \$$(filter %.cpp,$$^) $(INC1) $(INC2) -g" > $@

-include $(dep-list)

PHONY   += clean
clean:
    @echo "$(O)"
    rm -f $(target) $(obj-list) $(dep-list)

.PHONY: $(PHONY)

4.编译

在工程目录下make build即可

root@ubuntu:/home/sulier/work/AudioVedio/RTPZip/testRTP# make build 
make -f /home/sulier/work/AudioVedio/RTPZip/testRTP/script/makefile.build M=/home/sulier/work/AudioVedio/RTPZip/testRTP O=/home/sulier/work/AudioVedio/RTPZip/testRTP/out INC1=-I/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jrtplib/include/jrtplib3 INC2=-I/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jthread/include LIB1=-L/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jrtplib/lib L1=-ljrtp  LIB2=-L/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jthread/lib L2=-ljthread

make[1]: Leaving directory '/home/sulier/work/AudioVedio/RTPZip/testRTP'

5.运行

编译中虽然已经添加了jrtp库和jthread库，但是运行还是需要在本运行终端添加环境（临时运行方法，如果不想这么干的可能放到系统环境中）

export LD_LIBRARY_PATH=/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jrtplib/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jthread/lib

可以通过echo命令查看下是否已添加

root@ubuntu:/home/sulier/work/AudioVedio/RTPZip/testRTP# echo $LD_LIBRARY_PATH
/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jrtplib/lib:/home/sulier/work/AudioVedio/RTPZip/TestProject/export/jthread/lib

root@ubuntu:/home/sulier/work/AudioVedio/RTPZip/testRTP# ldd out/built-in.o 
        linux-vdso.so.1 =>  (0x00007ffc62ed1000)
        libjrtp.so.3.11.2 => /home/sulier/work/AudioVedio/RTPZip/TestProject/export/jrtplib/lib/libjrtp.so.3.11.2 (0x00007f760924c000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f7608eca000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f7608cb4000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f76088ea000)
        libjthread.so.1.3.3 => /home/sulier/work/AudioVedio/RTPZip/TestProject/export/jthread/lib/libjthread.so.1.3.3 (0x00007f76086e6000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f76084c9000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f76081c0000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f7609509000)

可以看出来库路径都已找到，然后执行文件是在out目录下built-in.o

root@ubuntu:/home/sulier/work/AudioVedio/RTPZip/testRTP# ./out/built-in.o 
Using version 3.11.2
Enter local portbase:

库路径都已找到，然后可以windows端编辑一个sdp文件

比如show.sdp，其中9004是接收端端口，25是帧率（代码中也是，可以自己对应修改），192.168.36.1是接收端IP

m=video 9004 RTP/AVP 96
a=rtpmap:96 H264/90000;
a=framerate:25
c=IN IP4 192.168.36.1

之后用VLC打开就行了

6.可能存在播放不了问题

关闭下防火墙
