MPEG 4.10/AVC/H.264 Encoding
H.264, MPEG-4 Part 10, or AVC, for Advanced Video Coding, is a digital video codec standard which is
noted for achieving very high data compression.
The ITU-T H.264 standard and the ISO/IEC MPEG-4 Part 10 standard (formally, ISO/IEC 14496-10)
are technically identical.

Creating AVC files, it is recommended to use the following parameters:

Multiplex Type: MPEG2 Transport Stream

Transport Stream composition:

The file should start with a transport sync byte (0x47) and should maintain packet alignment
throughout the entire duration.

There should be a minimal amount of fill packets at the start of the file.

The first non-fill packet should be the PAT packet.

The next non-fill packet should be the PMT packet(s).

The next non-fill packet should be the first video stream packet.

The first video stream packet should contain the following:

Adaptation indicator marking the presence of a PCR.

The adaptation flag field should have the discontinuity indicator set.

Valid PES header with PTS and DTS.

Valid video sequence header and GOP header.

Use the following recommended PID values:
PMT: 0x1e0 (480dec)
PCR: 0x1e1 (481dec, must reference video PID)
Video: 0x1e1 (481dec)
Audio1: 0x1e2 (482dec)
Audio2: 0x1e3 (483dec)

Audio: 192Kbps AC-3 or MPEG Layer 2

HD Content:

Resolution: High Profile up to 1920x1080 (1080i60 or 1080i50) Note that 1080i60 is not supported

Bit Rate: 25Mbps constant bit rate (CBR)

SD Content:

Resolution: Main Profile up to 720x480 NTSC or 720x576 PAL

Bit Rate: 5Mbps constant bit rate (CBR)

NOTE: Content should be padded with a couple black frames front and back for improved visual
transitions between clips.
