Yes, I have not changed the code of GstPlayer.cpp and GstDriver.cpp....I am using it as it was. GstPlayer uses MediaPlayerInterface class and accesses its mAudioSink variable which is an object of type sp<AudioSink>. Actually my device is not rooted, I don't know if that may have caused the problem. I am trying to build the project as an application (.apk) file. Please help. <div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">---------------------------------------------------------------------- Message: 1 Date: Tue, 07 Feb 2012 15:40:13 +0100 From: Xabier Rodriguez Calvar <<a href="mailto:xrcalvar@igalia.com">xrcalvar@igalia.com</a>> Subject: Re: Error setting AudioSink in GstPlayer To: <a href="mailto:gstreamer-android@lists.freedesktop.org">gstreamer-android@lists.freedesktop.org</a> Message-ID: <1328625613.2797.31.camel@localhost.localdomain> Content-Type: text/plain; charset="iso-8859-15" O Dom, 05-02-2012 ?s 10:50 +0530, Vikas Malhotra escribiu: > I've been working on getting GStreamer NDK Build working on my Android > 2.3.4 device. > I have successfully built the GStreamer source but I am getting error > while setting the AudioSink to the audioflingersink element in > GstPlayer using mAudioSink variable. > > Below given is the log showing the value = 0 (log was added by me in > GstPlayer's function setDataSource) > > 02-05 10:36:15.540: V/GstPlayer(2485): GstPlayer calling GstDriver :: > setAudioSink() with mAudioSink value = 0x0 > > Due to this I am not able to play any sound, and video is also not > playing. Please help me to solve the problem. Are yoy sure you are setting something valid? It looks like you have no element to set and that's causing a problem.
