Gstreamer udpsrc 错误 "reason error (-5)" 由于 "Invalid JPEG file structure: two SOF markers"

Question

我正在使用以下命令通过网络从摄像机接收 UDP 流：

gst-launch-1.0 udpsrc port=53247 ! jpegdec ! xvimagesink sync=false

我能够在几秒钟内正确接收来自摄像头的视频流，但随后视频停止并显示以下错误消息：

** (gst-launch-1.0:7888): CRITICAL **: gst_adapter_push: assertion 'GST_IS_BUFFER (buf)' failed
ERROR: from element /GstPipeline:pipeline0/GstUDPSrc:udpsrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2865): gst_base_src_loop (): /GstPipeline:pipeline0/GstUDPSrc:udpsrc0:
streaming task paused, reason error (-5)
Execution ended after 0:00:08.152866431
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...

有关流的唯一可用信息如下：

数据格式：UDP包/JPEG

图片分辨率：VGA (640 x 480)

帧速率：30 fps

我设法获得了有关将 --gst-debug-level=2 参数添加到我的命令的错误的更多信息。

显示的附加警告消息如下：

0:00:11.518477156  6569      0x2577940 WARN            videodecoder gstvideodecoder.c:3443:_gst_video_decoder_error:<jpegdec0> error: Failed to decode JPEG image

我的命令有什么问题？

Answer 1

基于我对这篇文章的修改，我终于找到了解决问题的方法：

Play two webcams in MJPG format simultaneously using gstreamer

运行命令如下（没有调试选项）：

gst-launch-1.0 udpsrc port=53247 ! 'image/jpeg,width=640,height=480,framerate=30/1' ! jpegparse ! jpegdec ! autovideosink sync=false

选项 do-timestamp=true 使我的视频在一段时间后出现延迟，所以我选择了选项 sync=false
