使用gstreamer将rtsp流保存到avi文件中

标签： video save gstreamer rtsp mpeg-4

我有一个视频服务器，它给了我一个视频＆amp; rtsp上的音频流。我可以使用gstreamer工具gst-launch使用命令：

来查看它 
gst-launch-1.0 uridecodebin uri=rtsp://path/to/source ! autovideosink

现在我需要将该视频流存储到文件中，以便随后在任何流行的视频播放器（VLC，Windows Media Player等）中播放。

我尝试将autovideosink替换为filesink location=file.avi，然后添加-e中推荐的gst-launch-1.0 -e rtspsrc location=rtsp://path/to/source ! decodebin ! x264enc ! mp4mux ! filesink location=file.avi 选项。文件已创建，但我认为它没有正确的视频格式（VLC无法播放）。

我也尝试了最近引用的答案：

ERROR: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2865): gst_base_src_loop (): /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0:
streaming task paused, reason not-linked (-1)

它给了我错误：

x264enc ! mp4mux

原因是（我认为）gst-launch-1.0 -e -v rtspsrc location=rtsp://192.168.101.44/moxa-cgi/multicaststream_ch1_stream1 ! decodebin ! avenc_mpeg4 ! mp4mux ! filesink location=file.mp4适用于H.264编解码器，但answer仅适用于MPEG4第2部分模式（MP4V-ES，即H.263）。所以我需要替换管道中的一些元素以满足我的设备的能力。但通过查看my device，我发现任何不适合MP4V-ES（H.263）的内容。

现在我的问题是：如何修改gst-launch命令将视频从稍微旧的设备保存到文件中以进一步播放？

具有详细程度的命令的完整日志：

2 个答案:

答案 0 :(得分：1)

使用avenc_mpeg4代替x264enc对我有用。最后的命令是：

  

gst-launch-1.0 -e rtspsrc location=rtsp://path/to/source ! decodebin ! avenc_mpeg4 ! mp4mux ! filesink location=file.avi

有效。但只有1次~10次。其他9次我得到的问题与问题相同：

  

流媒体任务已暂停，原因未链接（-1）

我不知道它的真正原因是什么。但我认为它的设备功能。

然而，命令如：

  

gst-play-1.0 rtsp://path/to/source

工作稳定，即没有错误。

答案 1 :(得分：1)

您所拥有的相机似乎正在制作MPEG4 Type 2流，您试图将其封装在mp4容器中。因此，x264_enc尝试将无法正常工作，因为流类型不兼容。其次，您不能像使用其他尝试一样使用带有AVI文件类型的MP4多路复用器，尽管您可以尝试使用av​​imux。打破从大写谈判中运作良好的流，我们可以将其构建为：

gst-launch-1.0 -v -e rtspsrc location=rtsp://path/to/source ! rtpmp4vdepay ! mpeg4videoparse ! mp4mux ! filesink location=test.mp4

rtpmp4vdepay，mpeg4videoparse和mp4mux通常包含在decodebin元素本身中，但只是为了让我们的生活更轻松，看看它出了什么问题把元素放在一边总是好的。它使您可以控制正在构建的管道，而不是让它进行大写协商，以确定我不建议使用IP摄像机。

我还建议尝试管道（尽管避免使用IP摄像机的解码器）：

gst-launch-1.0 -e rtspsrc location=rtsp://path/to/source ! decodebin ! avenc_mpeg4 ! mp4mux ! filesink location=file.mp4

在原始问题中说过this link后，会在尝试播放流时显示不同的协商格式。例如，工作的那个＆＃39;尝试按照上面工作管道中提到的顺序添加元素，并且非工作尝试通过添加rtppcmudepay元素来协商不同的格式。我认为这将取决于相机，它使得decodebin认为有多种类型的流可用，而decodebin旨在通过添加不需要的附加元素来解决这些限制。
