This article refers to the UMID SEI in Panasonic AVC-Intra files. UMID itself is a larger concept that is beyond the current scope of this page.
Panasonic UMID is an SEI in AVC-Intra that many decoders look for.
Some documentation of it will come here whilst it is reverse engineered. It is quite a complex structure so we will aim to document the bare minimum needed to implement AVC-Intra. Following UMID characters:
| Byte offset | Value (if any) | Comments |
|---|---|---|
| 0 | 0x13 | Always 0x13 |
| 1 | 0xff | Always 0xff |
| 2+3 | ?? | Some sort of counter but not all encoders increment. Would a playout server want this to increment? |
