大家好
这个问题不知道算不算解决了 我更换了queue
命令如下：
gst-launch -v v4l2src always-copy=FALSE input-src=component !\
'video/x-raw-yuv,format=(fourcc)NV12,width=(int)1280,height=(int)1024,framerate=(fraction)25/1' !\
TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE bitRate=1000000 !\
multiqueue !\
alsasrc !\
TIAudenc1 !\
avimux bigfile=FALSE !\
filesink location=output_cap2_.avi
用命令输入之后 打印如下：
gst-launch -v v4l2src always-copy=FALSE input-src=comp
onent !\
> 'video/x-raw-yuv,format=(fourcc)NV12,width=(int)1280,height=(int)1024,framerat
e=(fraction)25/1' !\
> TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE b
itRate=1000000 !\
> multiqueue !\
> alsasrc !\
> TIAudenc1 !\
> avimux bigfile=FALSE !\
> filesink location=output_cap2_.avi

提示是找不到声卡 因为硬件声卡还没有加进来
请问有明白的人 可以讲解下 这个命令行可以进行音视频的同步编码吗
谢谢各位了
