I am using GStreamer 1.8.0 on Android. When I initialize it using provided GStreamer.init the following messages appear in the log: 03-29 22:37:55.881 2115 2115 W VideoCapabilities: Unrecognized profile/level 0/0 for video/mpeg2 03-29 22:37:55.882 2115 2115 W VideoCapabilities: Unrecognized profile/level 0/2 for video/mpeg2 03-29 22:37:55.882 2115 2115 W VideoCapabilities: Unrecognized profile/level 0/3 for video/mpeg2 03-29 22:37:55.953 2115 2115 I VideoCapabilities: Unsupported profile 4 for video/mp4v-es 03-29 22:37:55.977 2115 2115 W VideoCapabilities: Unrecognized profile/level 0/0 for video/mpeg2 03-29 22:37:55.977 2115 2115 W VideoCapabilities: Unrecognized profile/level 0/2 for video/mpeg2 03-29 22:37:55.977 2115 2115 W VideoCapabilities: Unrecognized profile/level 0/3 for video/mpeg2 03-29 22:37:56.010 2115 2115 I VideoCapabilities: Unsupported profile 4 for video/mp4v-es 03-29 22:37:56.060 2115 2115 W GStreamer+amc: 0:00:00.627064163 0xa1c86320 gstamc.c:3491:gst_amc_codec_info_to_caps Unsupported mimetype 'audio/opus' 03-29 22:37:56.061 2115 2115 W GStreamer+amc: 0:00:00.628742392 0xa1c86320 gstamc.c:3491:gst_amc_codec_info_to_caps Unsupported mimetype 'audio/gsm' 03-29 22:37:56.083 2115 2115 W GStreamer+amc: 0:00:00.650981940 0xa1c86320 gstamc.c:3823:gst_amc_codec_info_to_caps Unsupported mimetype 'video/x-vnd.on2.vp9' 03-29 22:37:56.088 2115 2115 W GStreamer+amc: 0:00:00.655101092 0xa1c86320 gstamc.c:3506:gst_amc_codec_info_to_caps Unknown color format 0x7f000789 for codec video/3gpp 03-29 22:37:56.091 2115 2115 W GStreamer+amc: 0:00:00.658700975 0xa1c86320 gstamc.c:3506:gst_amc_codec_info_to_caps Unknown color format 0x7f000789 for codec video/avc 03-29 22:37:56.118 2115 2115 W GStreamer+amc: 0:00:00.685427449 0xa1c86320 gstamc.c:3506:gst_amc_codec_info_to_caps Unknown color format 0x7f000789 for codec video/mp4v-es 03-29 22:37:56.121 2115 2115 W GStreamer+amc: 0:00:00.688268534 0xa1c86320 gstamc.c:3506:gst_amc_codec_info_to_caps Unknown color format 0x7f000789 for codec video/x-vnd.on2.vp8 03-29 22:37:56.145 2115 2115 E GLib+GLib-GObject: g_object_class_install_property: assertion 'pspec->flags & G_PARAM_WRITABLE' failed I am not sure if this is related to plugins, but if it is, my list is: GSTREAMER_PLUGINS := coreelements audioconvert audiorate audioresample typefindfunctions autodetect playback ogg opus audioparsers opusparse androidmedia tcp rtsp rtp soup udp sdp opensles encoding debug autoconvert I have not encountered any issues because of this warning, but I am not using video elements.
commit 44770d22aa9ae8ae6986574132af71bf7a4c558f Author: Sebastian Dröge <sebastian@centricular.com> Date: Wed Mar 30 10:34:07 2016 +0300 ahcsrc: There's no point in read-only CONSTRUCT properties And creating one is causing assertions. Also get rid of the other CONSTRUCT property as it's a) unneeded for default initialization and b) you're not supposed to use constructor properties when creating element instances and the GStreamer API doesn't provide direct ways for doing so. https://bugzilla.gnome.org/show_bug.cgi?id=764339
