无法获取 SDP 说明：404 Stream not found testRTSPClient in LIVE555

Question

我是 Live555 的新手，最近开始学习一些关于它的东西。文档指出，一个好的测试是尝试源代码中 testProgs 文件夹中给出的示例。因此，我已经开始测试一些在 live555 源中很容易获得的程序。

从 mediaServer 文件夹我是运行服务器，根据文档我应该将电影文件 (mp4) 放在与 exe 相同的位置。我做到了。当我尝试打开客户端 (testRTSPClient.exe) 时，如屏幕截图所示，我不断收到 SDP 描述错误。

我做错了什么？这是否意味着我在客户端提供了一个 SDP 文件？在他们的文档中找不到这样的声明，目前还很晦涩。

Answer 1

live555MediaServer 不支持 mp4 文件。

当您启动它时，它会打印如下内容：

LIVE555 Media Server
    version 0.84 (LIVE555 Streaming Media library version 2014.09.11).
Play streams from this server using the URL
    rtsp://192.168.0.16:8554/<filename>
where <filename> is a file present in the current directory.
Each file's type is inferred from its name suffix:
    ".264" => a H.264 Video Elementary Stream file
    ".265" => a H.265 Video Elementary Stream file
    ".aac" => an AAC Audio (ADTS format) file
    ".ac3" => an AC-3 Audio file
    ".amr" => an AMR Audio file
    ".dv" => a DV Video file
    ".m4e" => a MPEG-4 Video Elementary Stream file
    ".mkv" => a Matroska audio+video+(optional)subtitles file
    ".mp3" => a MPEG-1 or 2 Audio file
    ".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file
    ".ogg" or ".ogv" or ".opus" => an Ogg audio and/or video file
    ".ts" => a MPEG Transport Stream file
        (a ".tsx" index file - if present - provides server 'trick play' support)
    ".vob" => a VOB (MPEG-2 video with AC-3 audio) file
    ".wav" => a WAV Audio file
    ".webm" => a WebM audio(Vorbis)+video(VP8) file
See http://www.live555.com/mediaServer/ for additional documentation.
(We use port 8000 for optional RTSP-over-HTTP tunneling, or for HTTP live streaming (for indexed Transport Stream files only).)

您应该使用其中一种受支持的格式，例如 mkv。
