您好：
本人对Gstreamer了解的不多，现在要用它完成一个TVP5150->encode->file的功能，不能实现。望专家帮忙解答。先谢谢了！
编经过测试，loopback的功能正常。
gst-launch -v v4l2src always-copy=FALSE input-src=composite ! video/x-raw-yuv, format=\(fourcc\)UYVY, framerate=25/1,width=720, height=576 ! TIDmaiVideoSink videoStd=D1_PAL videoOutput=composite contiguousInputFrame=TRUE sync=false
采用如下gst脚本：
gst-launch -v v4l2src always-copy=FALSE num-buffers=800 input-src=composite ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=720,height=576 ! queue ! TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE ! filesink location=output_cap_D1.h264
结果报错如下：
@0x001c2d46:[T:0x41299490] ti.sdo.dmai - [Venc1] Failed to open video encode algorithm: h264enc (0x0)
ERROR: from element /GstPipeline:pipeline0/GstTIVidenc1:tividenc10: failed to create video encoder: h264enc
可能是h264enc不支持UYVY模式。利用resize功能试试：
gst-launch -v v4l2src always-copy=FALSE num-buffers=800 input-src=composite ! 'video/x-raw-yuv,width=640,height=480,format=(fourcc)UYVY,framerate=(fraction)25/1' ! TIVidResize contiguousInputFrame=TRUE ! 'video/x-raw-yuv,width=320,height=240,format=(fourcc)NV12' ! TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE ! filesink location=output_cap_D1.h264
结果还是报错：
@0x0019d523:[T:0x4145b490] ti.sdo.dmai - [Resize] Failed to open /dev/davinci_resizer
ERROR: from element /GstPipeline:pipeline0/GstTIVidResize:tividresize0: failed to create resize handle
尝试ffmpegcolorspace
gst-launch -v v4l2src always-copy=FALSE num-buffers=800 input-src=composite ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=320,height=240 ! queue ! ffmpegcolorspace ! 'video/x-raw-yuv,width=320,height=240,format=(fourcc)NV12' ! TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE ! filesink location=output_cap_D1.h264
gstreamer没有报错，文件生成，但是用暴风影音播放，完全是闪动花屏。
请问问题在哪里？？
谢谢！
