 **Issue Summary:**
 There is a problem with MP3 file processing that occurs in FFmpeg 4.4 but
 not in 4.1.

 **Steps to Reproduce:**
 It doesn't matter whether it's ffmpeg, ffprobe or ffplay.

 In FFmpeg 4.1, the command ./ffprobe.exe -i - < out.mp3 successfully
 processes an MP3 file.

 However, in FFmpeg 4.4, attempting the same operation with the command
 ./ffprobe.exe -i - < new.mp3 results in failure.
