I have an HTC MyTouch 3G Slide (Android 2.1, API level 7). I am trying to write a program to record 320×240 h.264 video at 15fps, but I have 2 major problems. I would be grateful for a solution to either issue. Here is what I am doing:
mediaRecorder = new MediaRecorder();
mediaRecorder.setCamera(camera);
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
mediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setMaxDuration(600000);
mediaRecorder.setOutputFile("/sdcard/test.mp4");
mediaRecorder.setVideoFrameRate(15);
mediaRecorder.setVideoSize(320, 240);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.H264);
mediaRecorder.setPreviewDisplay(holder.getSurface());
mediaRecorder.setMaxFileSize(maxFileSizeInBytes);
mediaRecorder.prepare();
mediaRecorder.start();
Problem 1) H263 and MPEG_4_SP work fine, but H264 does not. On the call to prepare(), the logcat is filled with the errors below:

When using H.263 (which works), the error log only contains:

Problem 2) Although I am explicitly setting the framerate to 15fps, post-analysis of the clips shows strange framerates like 21.xx or 25.xx fps.
Why might H264 not be working, and why might MediaRecorder not be obeying my requested frame rate? Thanks in advance.
H.264 is only supported in Android 3.0+.
Check the CamcorderProfile to know which encoding profiles your device supports.
