Encode the input YUV file into eight streams by using eight encoder elements simultaneously.

For alternate input YUV formats, the following changes are required in the above pipeline:
| Format/Profile | Arguments |
|---|---|
| 4:2:2 8-bit (NV16) | format=nv16 profile=high-4:2:2 |
| 4:2:0 10-bit (NV12_10LE32) | format=nv12-10le32 profile=high-10 |
| 4:2:2 10-bit (NV16_10LE32) | format=nv16-10le32 profile=high-4:2:2 |
| 4:0:0 8-bit (GRAY8) | Not supported |
| 4:0:0 10-bit (GRAY10_LE32) | Not supported |
