tested successfully by using gst-launch but didn't work by using playbin2

I am working on playing avi file in Android using gstreamer which has been ported into Android with the help of http://groups.google.com.tw/group/prajnashi
Android don't support avi playing so i want to do it myself using gstreamer. Now it can play well using gst-launch under command line . But when i try to use laybin2 to do this job it failed. I have set properties "video-sink" and "audio-sink" of playbin2. I find that playbin2 found plugins avidemuxer and decoder successfully and stoped unexpectedly . The last error messages are as follows: D/GstPlayer( 1792): [1798], DEBUG mfw_gst_avidemuxer.c:499:avidemuxer_fill_stream_info: Added pad video_00 with caps 0xb03a0 D/GstPlayer( 1792): [1801], DEBUG gstdecodebin2.c:1827:gst_decode_group_check_if_blocked: Group isn't complete yet D/GstPlayer( 1792): [1798], DEBUG mfw_gst_avidemuxer.c:607:avidemuxer_fill_stream_info: out of gboolean avidemuxer_fill_stream_info D/GstPlayer( 1792): D/GstPlayer( 1792): [1798], DEBUG mfw_gst_avidemuxer.c:992:mfw_gst_avidemuxer_parse_header: signaling no more pads from mfw_avidemuxer D/GstPlayer( 1792): [1798], DEBUG gstdecodebin2.c:1979:gst_decode_group_expose: going to expose group 0xbf780 D/GstPlayer( 1792): [1798], DEBUG gstdecodebin2.c:2037:gst_decode_group_expose: About to expose dpad decodepad2 as src0 D/GstPlayer( 1792): [1798], DEBUG gstdecodebin2.c:2046:gst_decode_group_expose: emitting new-decoded-pad D/GstPlayer( 1792): [1798], DEBUG gsturidecodebin.c:671:new_decoded_pad_cb: new decoded pad, name: <src0>.

BTW:i do this job on freescale IMX27 board which supported hardware codec and freescale offers the plugins avidemuxer and decoder . Can anyone help me ? i will be appreciated. |

I'm new to gstreamer .And i wonder what the plugin "ffmepcolorspace" do ? I have looked into the source code but still have no idea. |

It adjust colorspace formats, e.g. converts YUV images between different packings or from/to rgb.

I set the property "video-sink" as follows: mPlayBin = gst_element_factory_make ("playbin2", NULL); mVideoSink = gst_element_factory_make("surfaceflingersink", NULL); g_object_set (mPlayBin, "video-sink", mVideoSink, NULL); I don't think that this results errors because when i use software codec plugins to make the pipeline it played well. The plugin videosink accepts buffers with the format of RGB565 and output to the screen using Android framework. I am confused that when i used plugin ffmpegcolorspace as the peer element,I found that the function "set_caps" of videosink was called when i played an avi file under command line by running "gst-launch-0.10 filesrc location=/sdcard/2.mp4 ! qtdemux name=demux demux. ! queue ! ffdec_aac ! audioflingersink demux. ! queue ! ffdec_mpeg4 ! ffmpegcolorspace ! surfaceflingersink" but when i used hardware decode plugins which were provided by freescale under command line by running "gst-launch-0.10 filesrc location=/sdcard/s.avi ! mfw_avidemuxer ! mfw_vpudecoder codec-type=std_avc ! surfaceflingersink" the function "set_caps" wasn't called .the src pad of decode plugin is same with the sink pad of surfaceflingsink. I don't know why. I wonder if this relates to the decode job which is done by a chip of dsp and that why it can play well by using gst-launch or making the pipeline manualy(not using playbin2) but resulted errors by using playbin2 . |

Does it accept buffers with the format of YUV and change them to RGB format ? |
