| Field name | Description | Type | Versions |
|---|---|---|---|
| opus | Frame Count.m | Unsigned integer (8 bits) | 3.6.0 to 4.4.2 |
| opus | Frame Count.p bit | Boolean | 3.6.0 to 4.4.2 |
| opus | Frame Count.v bit | Boolean | 3.6.0 to 4.4.2 |
| opus | Frame Data | Byte sequence | 3.6.0 to 4.4.2 |
| opus | Frame Size | Unsigned integer (16 bits) | 3.6.0 to 4.4.2 |
| opus | Padding | Byte sequence | 3.6.0 to 4.4.2 |
| opus | Additional padding bytes MUST be set to zero by the encoder | Label | 4.2.0 to 4.4.2 |
| opus | Padding Size | Unsigned integer (32 bits) | 4.2.0 to 4.4.2 |
| opus | TOC.C bits | Unsigned integer (8 bits) | 3.6.0 to 4.4.2 |
| opus | TOC.config | Unsigned integer (8 bits) | 3.6.0 to 4.4.2 |
| opus | TOC.S bit | Boolean | 3.6.0 to 4.4.2 |
| opus | Error:[R1] Packets are at least one byte. | Label | 3.6.0 to 4.4.2 |
| opus | Error:[R2] No implicit frame length is larger than 1275 bytes. | Label | 3.6.0 to 4.4.2 |
| opus | Error:[R3] Code 1 packets have an odd total length, N, so that (N-1)/2 is an integer. | Label | 3.6.0 to 4.4.2 |
| opus | Error:[R4] Code 2 packets have enough bytes after the TOC for a valid frame length, and that length is no larger than the number ofbytes remaining in the packet. | Label | 3.6.0 to 4.4.2 |
| opus | Error:[R5] Code 3 packets contain at least one frame, but no more than 120 ms of audio total. | Label | 3.6.0 to 4.4.2 |
| opus | Error:[R6] The length of a CBR code 3 packet, N, is at least two bytes, the number of bytes added to indicate the padding size plus the trailing padding bytes themselves, P, is no more than N-2, and the frame count, M, satisfies the constraint that (N-2-P) is a non-negative integer multiple of M. | Label | 3.6.0 to 4.4.2 |
| opus | Error:[R7] VBR code 3 packets are large enough to contain all the header bytes (TOC byte, frame count byte, any padding length bytes, and any frame length bytes), plus the length of the first M-1 frames, plus any trailing padding bytes. | Label | 3.6.0 to 4.4.2 |
