1.按照http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components_Multimedia_IVAHD.html 提示加载了M4 ipumm编码固件,在验证
nv12压缩h264时打印如下：
Pipeline is PREROLLING ...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Got EOS from element "pipeline0".
Execution ended after 0:00:00.000697840
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Setting pipeline to NULL ...
Freeing pipeline ...
但是编码的.h264文件0字节大小。测试命令使用如下：
gst-launch-1.0 filesrc location=/opt/dgp/web/video/jpeg.nv12 ! videoparse width=1344 height=640 format=nv12 ! video/x-raw,width=1344,height=640 ! ducatih264enc ! filesink location=/opt/dgp/web/video/test.h264
生成h264文件无效是什么引起？
2.当前版本是ipumm-3.00.09.01，使用ipumm-3.00.15.00时 内核提示/dev/rpmsg-dce不存在?
