| v4l2 plugins | |
| ============ | |
| The idea is a bit the same as the idea for the v4l1 plugins. We want | |
| one generic v4l2element, and a few child objects (probably only two: | |
| v4l2src and v4l2sink): | |
| /-------- v4l2src | |
| v4l2element ---= | |
| \-------- v4l2sink | |
| Both v4l2src and v4l2sink have a uncompressed and a compressed | |
| recording-/playback-mode. Since this is all part of v4l2, the 'client' | |
| of these elements, i.e. an application using v4l2src/v4l2sink, will | |
| hardly notice this. All capsnego stuff is done inside, and the plugin | |
| knows which formats are compressed and which are not. | |
| Please note that the v4l1 and the v4l2 plugins are *not* compatible | |
| concerning properties. Naming has been kept the same where possible, | |
| but in some cases, properties had to be removed or added to make | |
| full use of v4l2. | |
