streaming - RTSP 错误 - 分段错误

Question

播放以下 RTSP 插件时出现“分段错误”错误：

./TEST "( v4l2src always-copy=FALSE input-src=composite ! video/x-raw-yuv,format=\(fourcc\)NV12, width=320,height=240 ! queue ! dmaiaccel ! dmaienc_h264 encodingpreset=2 ratecontrol=2 intraframeinterval=23 idrinterval=46 targetbitrate=1000000 ! rtph264pay name=pay0 pt=96 )"

TEST 是来自 rtsp 示例的测试启动应用程序。我收到以下错误：

davinci_resizer davinci_resizer.2: RSZ_G_CONFIG:0:1:124
vpfe-capture vpfe-capture: IPIPE Chained
vpfe-capture vpfe-capture: Resizer present

vpfe-capture vpfe-capture: dma_alloc_coherent size 7168000 failed
Segmentation fault

谁能告诉我出了什么问题。

谢谢，马兹

See vpfe-capture vpfe-capture: dma_alloc_coherent size 7168000 failed

memory allocation has failed somewhere in your capture driver. This question is better suited for TI's e2e list, no? I don't think this ia a gstreamer generic issue but issue specific to the embedded hardware.

Why don't you get a simple filesrc ! h264parse ! rtph264pay pipeline up first and then slowly make it more and more complicated. [replace bitstream with yuv and do encoding, then add the capture]
