<div dir="ltr">i did.. caps after filesrc : g_object_set (G_OBJECT (flt1), "caps", gst_caps_new_simple ("video/x-raw-yuv", "format",GST_TYPE_FOURCC, GST_MAKE_FOURCC ('I','4','2','0'), "width",G_TYPE_INT,(gint)value2, "height",G_TYPE_INT,(gint)value1,"framerate", GST_TYPE_FRACTION, 25, 1, NULL),NULL); i think i hv gotten rid of that problem ... but now there is another exception ::gst_ffmpegenc_chain_video: assertion `frame_size == GST_BUFFER_SIZE (inbuf)' failed the pipeline ::: pipeline = gst_pipeline_new ("player"); source = gst_element_factory_make ("filesrc", "source"); g_object_set (G_OBJECT (source), "location", Inputfile, NULL); flt1 = gst_element_factory_make ("capsfilter","flt1"); g_object_set (G_OBJECT (flt1), "caps", gst_caps_new_simple ("video/x-raw-yuv", "format",GST_TYPE_FOURCC, GST_MAKE_FOURCC ('I','4','2','0'), "width",G_TYPE_INT,(gint)value2, "height",G_TYPE_INT,(gint)value1,"framerate", GST_TYPE_FRACTION, 25, 1, NULL),NULL); encoder = gst_element_factory_make ("ffenc_mpeg2video", "encoder"); //g_print("%f %f", value4,value3 ); g_object_set (G_OBJECT (encoder), "bitrate", (glong)value4,"buffer-size", (glong)value3, NULL); ///////////////////////////////// the capsfilter element is linked between the filesrc and the encoder as you would've guessed. there also is a decoder following this.. but first i need to figure this out... i have specified the buffer size as the standard yuv 4:2:0 cif framesize.. still the exception is ther.
