What is the difference between H.264 video and MPEG-4 video?

Question

Are they the same? Is the H.264 MPEG-4 Codec? What if I need to convert FLV to H.264 high definition video format? I want to make online streaming TV and want to use PHP or Python.

Answer 1

H.264 is a new video compression standard that has more advanced compression methods than MPEG-4 basic compression. One of the benefits of H.264 is its high compression ratio. This is about 1.5-2 more efficient than MPEG-4 encoding. This high compression ratio allows you to record more information on the same hard drive.
Image quality is also better, and playback is freer than with MPEG-4 basic compression. However, the most interesting feature is the lower data rate required for transmission over the network.
Thus, the 3 main advantages of H.264 compression over MPEG-4 are:
- Small file size for longer recording time and better network transfer.
- Free and best quality video for live playback
- More efficient mobile surveillance application

H264 is now fixed in MPEG4 as part 10, also known as AVC

Hope this helps.

Answer 2

These are names for the same standard from two different industries with different naming methods, guys who make and sell films, and guys who transfer films over the Internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Prior to this, the relationships were slightly weaker in that they are not equal, but the MPEG 4 Part 2 decoder can display a stream that is H.263 . The following standard: MPEG H Part 2 "=" H.265 "=" HEVC "
