I want to develop an android application which can record a video (mp4), then I have some audio files (mp3) in my resources folder, and I want to add it to the end of the video. So the final effect will be like first the video is played and at the end of video the added audio will be heard. how can I do it?

推荐答案

很难对具有不同音频编解码器的文件进行合并.我将执行以下操作:

Combing to files with different audio codecs is not easily possible. I would do the following:

• 将MP3文件转换为与视频相同的格式(最有可能是MP4容器中的AAC)
• 现在，您可以使用 mp4parser 的

• convert the MP3 files to the same format as the video (most likely AAC in an MP4 container)
• Now you can use mp4parser's AppendExample to append the recorded video with the pre-recorded sound
• The result will be one MP4 file containing the video first and the sound.

全部披露:我是mp4parser的维护者.
