i recording video mediarecorder. code works fine on 2.3.3 fails on 4.0.3.

the issue following: code mediarecorder.stop() throws runtimeexeption

java.lang.runtimeexception: stop failed.     @ android.media.mediarecorder.stop(native method)

with logcat message

04-05 15:10:51.815: e/mediarecorder(15709): stop failed: -1007

update

i've found, mediaplayer reports error (via mediaplayer.onerrorlistener) after start. error code 100 (media server died), -1007.

update 2 code prepare mediarecorder

            c = camera.open();      ...      // step 1: unlock , set camera mediarecorder     camera.unlock();     mediarecorder.setcamera(camera);      // step 2: set sources     mediarecorder.setaudiosource(mediarecorder.audiosource.camcorder);     mediarecorder.setvideosource(mediarecorder.videosource.camera);      // step 3: set camcorderprofile (requires api level 8 or higher)     camcorderprofile profile = camcorderprofile             .get(camcorderprofile.quality_high);      // manual set up!      mediarecorder.setoutputformat(mediarecorder.outputformat.mpeg_4);      mediarecorder.setvideoencodingbitrate(profile.videobitrate);     mediarecorder.setvideoframerate(profile.videoframerate);     mediarecorder.setvideosize(profile.videoframewidth,             profile.videoframeheight);      mediarecorder.setaudiochannels(profile.audiochannels);     mediarecorder.setaudioencodingbitrate(profile.audiobitrate);     mediarecorder.setaudiosamplingrate(profile.audiosamplerate);      mediarecorder.setaudioencoder(profile.audiocodec);     //mediarecorder.setvideoencoder(mediarecorder.videoencoder.mpeg_4_sp);     mediarecorder.setvideoencoder(profile.videocodec);      // mediarecorder.setprofile(profile);      // step 4: set output file     mediarecorder.setoutputfile("somefile.mp4");      // step 5: set preview output     mediarecorder.setpreviewdisplay(preview.getholder().getsurface());      // step 6: prepare configured mediarecorder     try {         mediarecorder.prepare();     } catch ...     { release mediarecorder}

then simplycall mediarecorder.start() please note, need video encoded mp4 format. code works on samsng galaxy gio (android 2.3.3) , fails described on acer e305 (android 4.0.2)

any ideas? thanks.

solved @ last. issue setting preview size before setting actual preview camera. preview size must equal selected video size.

camcorderprofile profile = [get required profile];  camera.parameters parameters = mcamera.getparameters(); parameters.setpreviewsize(profile.videoframewidth,profile.videoframeheight); mcamera.setparameters(parameters);  mcamera.setpreviewdisplay([surface holder]); mcamera.startpreview();  ...  //configure mediarecorder , call mediarecorder.start()
