Record video with Media Recorder in WEBM format
21 mai 2017, par MathoI need to record two videos via media recorder and process them with ffmpeg in Android. I want to read videos via pipe in ffmpeg command string. From what I have read, I could not use 3GPP/MP4 format, because these formats contains header at the end of video. Because of it, I want to use WEBM video format, but my app is crashing, when I use webm/vp8 setting in media recorder. Ffmpeg I’m using is : com.writingminds:FFmpegAndroid:0.3.2. Could you help me please ?
