decodebin - static linking of decoder and sink

[Ash 20001]

Hi Sebastian,Here is the pipeline picture from within my C++ app using appsrc where I am trying to statically create pipeline. Also attached is the DEBUG log (zipped)...I think the key portion is this:D/GST_LOG (22134): : (0) > [_0_] 0:00:05.562008914 0xb423b690 DEBUG               GST_CAPS gstpad.c:5034:pre_eventfunc_check:<omx_h264dec:sink> caps video/x-h264, width=(int)1280, height=(int)720, framerate=(fraction)0/1, parsed=(boolean)true, stream-format=(string)avc, alignment=(string)au, level=(string)4, profile=(string)high, codec_data=(buffer)01640028ffe1000b67640028ac34ec05005b9001000468ea438b not acceptedI am not sure why this is not accepted as the sink pad on omx_h264dec says:  SINK template: 'sink'    Availability: Always    Capabilities:      video/x-h264                  width: [ 0, 1920 ]                 height: [ 0, 1088 ]               maxwidth: [ 0, 1920 ]              maxheight: [ 0, 1088 ]              framerate: [ 0/1, 2147483647/1 ]

Get a debug log and check where the not-negotiated comes from. Most
likely you need at least a videoconvert between decoder and sink.
 
Also your pipeline graph is *not* from decodebin but from your manual
pipeline.
