hi When i try to to set up a pipeline to encode raw video to mpeg2 using ffenc_mpeg2video i am getting segmentation fault. Are these following pipelines correct?  I first covert a mpeg video to raw video data using pipeline "gst-launch filesrc location=/test.mpg ! decodbin ! filesink location=/test.raw" And then i use the raw data to convert it to the mpeg2 video using pipeline "gst-launch filesrc location=/test.raw ! ffmpegcolorspace ! ffenc_mpeg2video ! filesink location=/test1.mpv" The first one works fine, but second one gives segmentation fault. And when i try to install the bad plugins from source after doing ./configure it displays a list of plugins  containing  mpeg2enc, faac,faad etc , that those plugins can't be build. Can anyone please tell me on what external libraries it depends. Or is there any alternative way to install those bad plugins. Looking forward for your help. Warm Regards Gajel Kumar
