NULL caps question

[Jorge Fernandez Monteagudo]

Hi all,

I would like to know how to solve a problem I have running the next pipeline:

# gst-launch filesrc location=/home/root/video31_aac.mp4 ! qtdemux ! omx_mpeg4dec ! gpuvsink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
Width :800, Height: 600

(gst-launch-0.10:1518): GStreamer-CRITICAL **: gst_pad_fixate_caps: assertion `!gst_caps_is_empty (caps)' failed

(gst-launch-0.10:1518): GStreamer-CRITICAL **: gst_pad_set_caps: assertion `caps == NULL || gst_caps_is_fixed (caps)' failed

** (gst-launch-0.10:1518): CRITICAL **: gst_render_bridge_set_caps: assertion `caps' failed

I've checked the gpuvsink code and I've found the failed assert .

static gboolean
gst_render_bridge_set_caps (GstBaseSink * bsink, GstCaps * caps)
{
  GstBufferClassSink *gpuvsink = GST_BCSINK (bsink);

  g_return_val_if_fail (caps, FALSE);
  g_return_val_if_fail (gst_caps_is_fixed (caps), FALSE);

...

Is it possible to force a caps from the command line?

Regards,
Jorge
