Are these both the same? Is H.264 codec of MPEG-4? What if I need to convert flv to high definition H.264 video format? I want make online tv streaming and want to use PHP or Python.

MPEG-4 is a step in the natural progression of encoding methods, as the internet has created an environment where online and mobile streaming are the primary forms of video consumption. Ultimately, both MPEG-2 and MPEG-4 are capable of maintaining high-definition video quality.
MPEG4 is a codec. It's a compression method by Moving Picture Experts Group that developed standards for video and audio encoding. Unlike other formats compressed with MPEG, MPEG-4 formats can store still images, subtitles, video, audio, and other essential data.
H. 264 is a well-known video compression standard for high-definition digital video. Also known as MPEG-4 Part 10 or Advanced Video Coding (MPEG-4 AVC), H. 264 is defined as a block-oriented, compensation-based video compression standard that defines multiple profiles (tools) and levels (max bitrates and resolutions).
Benefits of using H.H. 264 was created to provide high-quality transmission of full-motion video with lower bandwidth requirements and lower latency traditional video standards, such as MPEG-2. H. 264 uses a very efficient codec that provides high-quality images and uses a minimal amount of bandwidth.
H.264 is a new standard for video compression which has more advanced compression methods than the basic MPEG-4 compression. One of the advantages of H.264 is the high compression rate. It is about 1.5 to 2 times more efficient than MPEG-4 encoding. This high compression rate makes it possible to record more information on the same hard disk.
The image quality is also better and playback is more fluent than with basic MPEG-4 compression. The most interesting feature however is the lower bit-rate required for network transmission.
So the 3 main advantages of H.264 over MPEG-4 compression are:
‐ Small file size for longer recording time and better network transmission.
‐ Fluent and better video quality for real time playback
‐ More efficient mobile surveillance applicationH264 is now enshrined in MPEG4 as part 10 also known as AVC

Hope this helps.

They are names for the same standard from two different industries with different naming methods, the guys who make & sell movies and the guys who transfer the movies over the internet. Since 2003: "MPEG 4 Part 10" = "H.264" = "AVC". Before that the relationship was a little looser in that they are not equal but an "MPEG 4 Part 2" decoder can render a stream that's "H.263". The Next standard is "MPEG H Part 2" = "H.265" = "HEVC"
