" Stream copy |
| 13 |
Stream copy is a mode selected by supplying the "copy" parameter to |
| 14 |
the |
| 15 |
-codec option. It makes ffmpeg omit the decoding and encoding step |
| 16 |
for |
| 17 |
the specified stream, so it does only demuxing and muxing. It is |
| 18 |
useful |
| 19 |
for changing the container format or modifying container-level |
| 20 |
metadata. " |
