I am experimenting with a new app to do Time Lapse Video Recording for API level 11 (Android 3.0 and newer). I am following the API Guide for Camera (to do time lapse recording), here: http://developer.android.com/guide/topics/media/camera.html#time-lapse-video
I am using the Profiles of the CamcorderProfile class, both for normal and time lapse recording. Normal video recording works fine. But when I try to do time lapse recording - just by adding a few lines of code - exactly as described in the API Guide - I start having problems. The time lapse recording works OFTEN - but not always. Sometimes it fails when I stop the recording. Then the MediaRecorder seems to be locked (in some way) at the currently used profile, e.g. CamcorderProfile.QUALITY_HIGH. Afterwards the recorder will not start again using that particular profile (neither using normal nor time lapse recording), but it will start using other profiles, e.g. CamcorderProfile.QUALITY_LOW. A device power cycle is required to be able to record again at these "locked" profiles. When this happens, the native/built-in camera app of the device can be used to take pictures, but NOT to record video. I am not showing any code here, as it is almost identical to that of the API Guide referred to. I have googled a lot to see if this issue has been discussed elsewhere, but it seems that very litte has been written about time lapse recording yet. This is part of the log I get when the time lapse recording fails when the recording stops: 09-20 09:28:22.189: W/IMediaDeathNotifier(4719): media server died 09-20 09:28:22.189: E/MediaPlayer(4719): error (100, 0) 09-20 09:28:22.189: W/AudioSystem(5360): AudioFlinger server died! 09-20 09:28:22.189: W/IMediaDeathNotifier(5360): media server died 09-20 09:28:22.189: I/ServiceManager(132): service 'media.audio_flinger' died 09-20 09:28:22.189: I/ServiceManager(132): service 'media.player' died 09-20 09:28:22.189: I/ServiceManager(132): service 'media.camera' died 09-20 09:28:22.189: I/ServiceManager(132): service 'media.cameraextension' died 09-20 09:28:22.189: I/ServiceManager(132): service 'media.audio_policy' died 09-20 09:28:22.189: W/IMediaDeathNotifier(4933): media server died 09-20 09:28:22.189: W/Camera(4933): Camera server died! 09-20 09:28:22.189: I/BootReceiver(309): Copying /data/tombstones/ tombstone_01 to DropBox (SYSTEM_TOMBSTONE) 09-20 09:28:22.199: W/MediaMetadataRetriever(3401): MediaMetadataRetriever server died! 09-20 09:28:22.199: W/Camera(4933): ICamera died 09-20 09:28:22.199: W/AudioEffect(309): IEffect died 09-20 09:28:22.199: E/MediaPlayer(4719): Error (100,0) 09-20 09:28:22.199: D/kernel(146): [19950.840118] binder: release 5071:5071 transaction 566682 in, still active 09-20 09:28:22.199: D/kernel(146): [19950.840148] binder: send failed reply for transaction 566682 to 4933:5926 09-20 09:28:22.199: D/kernel(146): [19950.840423] binder: 4933:5926 transaction failed 29189, size 60-0 09-20 09:28:22.199: E/Camera(4933): Error 100 09-20 09:28:22.199: W/AudioSystem(309): AudioFlinger server died! 09-20 09:28:22.199: E/AudioEffectService(309): binderDied : AudioFlinger is dead. 09-20 09:28:22.199: W/AudioEffects-JNI(309): EVENT_ERROR 09-20 09:28:22.199: W/AudioSystem(309): AudioPolicyService server died! 09-20 09:28:22.209: E/kernel(146): [19950.843841] [audpp.c:audpp_disable] Didn't receive CFG_MSG DISABLE message from ADSP 09-20 09:28:22.209: D/kernel(146): [19950.843872] [audpp.c:audpp_dsp_event] DISABLE 09-20 09:28:22.209: D/kernel(146): [19950.843872] [adsp.c:msm_adsp_put] closing module AUDPPTASK I shall appreciate any suggestions as to solve this issue.
