Video Recorded from Android MediaRecorder Corrupted on Samsung Galaxy S2

Question

Good afternoon! I am learning how to record video using MediaRecorder, but the recorded video is damaged when I play it. See this screenshot: http://www.4shared.com/photo/QtmJCHRi/corrupted-video.html . Which camera can see the image, marked with a red rectangle in the upper left corner. But it is so small, it is repeated, and there are many green areas. Please let me know what I am doing wrong. HW - Samsung Galaxy S2 (GT-I9100, Android 2.3.5). I tried following this guide: http://developer.android.com/guide/topics/media/camera.html#saving-media

Thank you in advance!

Answer 1

I read about it somewhere (I think it was in SO). The problem is that, apparently, the Samsung Galaxy does not support writing to HIGH QUALITY (CamcorderProfile.QUALITY_HIGH).

Try using CamcorderProfile.QUALITY_LOW. to find out if it works.
