Hi,

So I have the following code:

var cont_format = Caps.from_string ("video/mpegts,"
                                     + "systemstream=True,"
                                     + "packetsize=188");

var video_format = Caps.from_string ("video/mpeg,mpegversion=(int)2,"
                                             + "systemstream=(boolean)false,"
                                             + "framerate=25/1");

var audio_format = Caps.from_string ("audio/x-ac3");

var enc_container_profile = new EncodingContainerProfile("container",
                                                         null,
                                                         cont_format,
                                                         null);
var enc_video_profile = new EncodingVideoProfile (video_format,
                                                  null,
                                                  video_restriction,
                                                  1);
var enc_audio_profile = new EncodingAudioProfile (audio_format,
                                                  null,
                                                  null,
                                                  1);

enc_container_profile.add_profile (enc_video_profile);
enc_container_profile.add_profile (enc_audio_profile);


but when I try to play the pipeline I get...
GStreamer-CRITICAL **: gst_element_get_compatible_pad: assertion `GST_PAD_PEER
(pad) == NULL' failed

it does work nicely when audio_format = Caps.from_string ("audio/mpeg");

why aren't the pads compatible? how to fix this?
