我现在在函数rtsp_ondescribe()中把if(it == s_describes.end())的执行路径注释掉了; 现在通过抓包看到describe回应报文里有开头的v=0 o=xxx之类, 也有分别关于video,audio的m=xx,a=xx; 也有payload type=98; payload type=102的报文, 但VLC没声音; 我把抓取的报文附上, 帮忙分析下, 多谢! |

我在linux下启用_HAVE_FFMPEG_宏定义, 在makefile中添加了相关INCLUDES, LIBPATHS, LIBS后能成功编译, 但运行test -c rtsp_example后, 通过windows下的VLC播放器播放无声音只有视频, 不启用此宏是有声音和视频的. 请问是哪儿需要修改吗? 我使用的ffmpeg-4.3.4版本
