How can I get specific h264 video information from video file? I need to know profile (Baseline/Main/High) and is there B-Frames in movie?

Finding Your Video Codec You may need to right-click the video title and select Play with VLC Media Player, if VLC is not your default video player. Once the video starts, select Tools > Codec Information. Here, you'll see the codec for the video.
From the respective definition above, we can easily see that MP4 is a file container format, while H. 264 is actually a video compression codec that requires a video container to host the encoded video. They are different things, not even with the same property.
H. 264 or MPEG-4 AVC (Advanced Video Coding) is a video coding format for recording and distributing full HD video and audio. It was developed and maintained by the ITU-T Video Coding Experts Group (VCEG) with the ISO/IEC JTC1 Moving Picture Experts Group (MPEG).
The H. 265 codec compresses information more efficiently than H. 264, resulting in files of comparable video quality that are about half the size.
I've found out that the best way for this is using FFprobe with -show_streams parameter. It shows both h.264 profile and B-frames usage for video streams of the movie.
ffprobe -show_streams -i "file.mp4"
