我想从视频文件中获取音频比特率并将其保存。
是否可以使用ffmpeg从视频文件中单独获取音轨比特率?
如果可能的话该怎么做?...任何建议将不胜感激。
最佳答案
也许这会帮助您:
@Override
public void onProgress(String message) {
Log.e("ryeure", "onProgress: ");
String findWithinHorizon = new Scanner(message).findWithinHorizon(Pattern.compile(".?fltp,\\s([0-9]*)\\skb/s"), 0);
Log.e("ryeure", "onProgress: findwithinhorizon---" + findWithinHorizon);
if (findWithinHorizon != null) {
String intValue = findWithinHorizon.replaceAll("[^0-9]", "");
result_audioBitrate = Integer.parseInt(intValue) * 1000;
}
}
@Override
public void onFailure(String message) {
Log.e("ryeure", "onFailure: onfailure--" + result_audioBitrate);
audio_origin_bitrate.setText("Origin bitrate : " + result_audioBitrate + " kb/s");
audio_new_bitrate.setText("New bitrate : " + result_audioBitrate + " kb/s");
}
