For now, I am using gst-launch to test the plugin but an error occurs: gst-launch filesrc location=xxx.avi ! ffdemux_avi ! xxxdec ! fbdevsink ERROR: from element /pipeline0/ffdemux_avi0: Internal data stream error. Additional debug info: gstffmpegdemux.c(1300): gst_ffmpegdemux_loop (): /pipeline0/ffdemux_avi0: streaming stopped, reason not-negotiated ERROR: pipeline doesn't want to preroll. While the last plugin is substituted by fakesink or filesink, the pipeline works ok. I've gst-inspected the decoder and fbdevsink, the src pad of decoder and the sink pad of fbdevsink both have the cap GST_VIDEO_CAPS_RGB_16. I've also edited the caps of decoder output buffer:  buf->caps = GST_PAD_CAPS (filter->srcpad); Is there something I missed or got wrong with the plugin? Thanks in advance.
