ffmpeg H264 字节流转图像或视频文件 [Java]

Question

I have a Java function which receives bytes of an H264 stream as follows:

void bytesReceived(byte[] bytes, int size)

Using ffmpeg, how can I transcode these bytes to some sort of image format? I would be happy with mp4, jpeg, etc. I've seen lots of examples using files and ffmpeg, but I don't know how I'd use the command line operations it offers to handle a stream of bytes.

Thanks.

Since you incoming data is already compressed (H.264) and you are fine with MP4. I'd use https://github.com/sannies/mp4parser to just wrap your incoming H.264 stream into a MP4 file in pure Java.
