There is no Video decoder element in your pipeline. You pipeline should be something like this, mx27# gst-launch filesrc location=/mnt/nfs/Toyata_Human_Touch.mpg ! <Demuxer> ! <Video Decoder> ! ffmpegcolorspace ! mfw_v4lsink >From your list of plugins, I see that mfw_vpudecoder is a valid plugin. This plug-in is capable of decoding MPEG4, H.264, H.263 streams. Vinay K.
