如何在FFMPEG流中播放音频文件数据？
亲爱的FFMPEG实用程序的尊敬的专家！告诉我谁知道这一点： 我想通过循环视频和音轨在YouTube音乐上进行24/7流。 我这样做是这样的：
ffmpeg -loglevel info -stream_loop -1 -y -re \
-i video.mp4 \
-f concat -safe 0 -i playlist.txt \
-c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 6000k \
-framerate 25 -video_size 1280x720 -vf "format=yuv420p" -g 50 -shortest -strict experimental \
-c:a aac -b:a 128k -ar 44100 \
-f flv rtmp://localhost/live/my-stream
IE Video.mp4在循环中旋转，从playlist.txt文件中我播放mp3。 这样，一切都可以，一切都可以。但是我也想显示比赛曲目的标题。 例如，在一些YouTube收音机上：
封面非常完美！
有什么想法如何实施？
我知道可以通过绘制文字显示文本。您可以从文件中输出文本，您可以单独更新自己。但是如何获取当前播放文件的数据？ FFMPEG不提供此类信息，仅提供流参数：fps，framerate ...还是可以得到它？
还是有更好，更轻松的方法？
事先感谢您的帮助！
Dears experts of the wonderful ffmpeg utility! Tell me please who knows this:
I want to make a 24/7 stream on YouTube of music from looped video and audio tracks.
I do it like this:
ffmpeg -loglevel info -stream_loop -1 -y -re \
-i video.mp4 \
-f concat -safe 0 -i playlist.txt \
-c:v libx264 -preset veryfast -b:v 3000k -maxrate 3000k -bufsize 6000k \
-framerate 25 -video_size 1280x720 -vf "format=yuv420p" -g 50 -shortest -strict experimental \
-c:a aac -b:a 128k -ar 44100 \
-f flv rtmp://localhost/live/my-stream
i.e. video.mp4 is spinning in a loop and from the playlist.txt file I play mp3 in turn.
With this everything is ok, everything works. But I also want to show the title of the playing track.
As for example on some YouTube radios:
With cover is perfect!
Any ideas how this can be implemented?
I know that it is possible to display text through drawtext. You can output text from a file, which you can separately update yourself. But how to get the data of the currently playing file? ffmpeg does not give such information, only stream parameters: fps, framerate... Or is it still possible to get it?
Or are there better and easier ways?
Thanks in advance for your help!

您可以使用 ffprobe 从文件中提取元数据。
