| MPEG2 - 32 byte entries | |
| Offset Purpose Value | |
| -------------------------------------------------------------------------------------------------------------- | |
| 0x00 3 bytes Offset from Seq. header to current frame. Address of this frame minus address of Sequence header. | |
| 0x03 1 byte Frame Type 0x01 = I-Frame, 0x02 = P-Frame, 0x03 = B-Frame. | |
| 0x04 1 byte SD/HD flag 0x20 = SD. | |
| 0x05 1 byte Picture sequence frame count 0 to 12 (13 frames) for first count only, then 3 to 14 (12 frames) after that. | |
| 0x06 2 byte Offset from Seq. header to first frame. Address of first frame in Sequence minus address of Sequence header. | |
| 0x08 8 bytes Picture header address. Address of this frame. | |
| 0x10 4 bytes Presentation TimeStamp (PTS) The first 32 bits of PES PTS. | |
| 0x14 4 bytes Frame size. Address of next frame minus address of this frame. | |
| 0x18 4 bytes Played Time Played time in milliseconds. | |
| 0x1C 4 bytes Unused N/A | |
| H264 - 64 byte entries | |
| Offset Purpose Value | |
| -------------------------------------------------------------------------------------------------------------- | |
| 0x00 3 bytes Offset from PicParamSet to current SEI. Address of SEI preceding current frame minus address of last PicParamSet. | |
| 0x03 1 byte Frame Type 0x01 = I-Frame, 0x02 = P-Frame, 0x03 = B-Frame. | |
| 0x04 1 byte HD Flag 0x30 = HD. | |
| 0x05 1 byte Picture sequence frame count. Starts at zero for first count only, then starts at 1 after that. Consequently the last 0x08 entry of each count sequence contains the address of first SEI of the next sequence. | |
| 0x06 2 bytes Offset from PicParamSet to first SEI. Address of first SEI in sequence minus address of last PicParamSet. | |
| 0x08 8 bytes SEI address. Address of SEI preceding the frame. | |
| 0x10 4 bytes Presentation TimeStamp (PTS) The first 32 bits of PES PTS. | |
| 0x14 4 bytes Frame size. Address of the AUD immediately after frame minus address of SEI preceding the frame. | |
| 0x18 4 bytes Played Time. Played time in milliseconds for timebar display. | |
| 0x1C 4 bytes Unused N/A | |
| 0x20 4 bytes HeaderEndSize Address of SEI minus address of last SeqParamSet | |
