I want to output elementary video streams with media recorder in android for the purpose of streaming with live555. In essence, I want to get media recorder to output an MPEG-4 Video Elementary Stream file (an .m4e file) or an H.264 Video Elementary Stream file (an .264 file). Is it possible to do that with media recorder on android? Or is there any other way to get it work?
推荐答案
答案是，据我了解，这是不容易做到的，与 MediaRecorder 同时记录。你可以做到这一点没有太大的困难，使用的ffmpeg 一旦视频录制。其原因是，的MediaPlayer 不能记录为基本流。即使我们只记录视频，它将被放置在一个容器格式诸如3GPP或MP4。现在，像的ffmpeg 对这些文件的工作工具，他们需要的3GPP或MP4头信息必须在录制的文件present。但是，的MediaPlayer 将写那些标头后，才录制完成的文件。
The answer is, as I understand, that it is not easy to do that with MediaRecorder while recording. You may do that without much difficulty, using ffmpeg once the video is recorded. The reason is that, MediaPlayer cannot record as elementary streams. Even if we record video only, it will be put in a container format such as 3GPP or MP4. Now, for tools like ffmpeg to work on these files, they need the 3GPP or MP4 header information must be present on the recorded file. But, MediaPlayer will write those headers to the file only after it finished recording.
