Description

Sample example RecordActivity crashes when I stop recording a video:

FATAL EXCEPTION: main
Process: ffmpegrecorder, PID: 23433
java.lang.ArrayIndexOutOfBoundsException: length=300; index=-1
    at com.github.crazyorr.ffmpegrecorder.RecordActivity.stopRecording(RecordActivity.java:251)
    at com.github.crazyorr.ffmpegrecorder.RecordActivity.onClick(RecordActivity.java:549)

Contributor guide

Research direction
Check the stopRecording method in RecordActivity.java around line 251. The ArrayIndexOutOfBoundsException indicates an array index of 1, so look for where an index is set to 1 or not properly initialized before use.
