| The only capture method implemented currently is mmap. |

| Missing V4L2 ioctls to be implemented at library: |
| Methods to change controls at V4L devices: |
| VIDIOC_QUERYCTRL |
| VIDIOC_QUERYMENU |
| VIDIOC_G_CTRL |
| VIDIOC_S_CTRL |
| VIDIOC_TRY_EXT_CTRLS |
| VIDIOC_G_EXT_CTRLS |
| VIDIOC_S_EXT_CTRLS |
| |
| Tuner control methods: |
| VIDIOC_G_TUNER |
| VIDIOC_S_TUNER |
| VIDIOC_S_FREQUENCY |
| VIDIOC_G_FREQUENCY |
| |
| Crop methods: |
| VIDIOC_CROPCAP |
| VIDIOC_S_CROP |
| VIDIOC_G_CROP |
| |
| Audio input/output: |
| VIDIOC_ENUMAUDIO |
| VIDIOC_ENUMAUDOUT |
| VIDIOC_G_AUDIO |
| VIDIOC_S_AUDIO |
| VIDIOC_G_AUDOUT |
| VIDIOC_S_AUDOUT |
| |
| Video output: |
| VIDIOC_ENUMOUTPUT |
| VIDIOC_G_OUTPUT |
| VIDIOC_S_OUTPUT |
| |
| Priority control: |
| VIDIOC_G_PRIORITY |
| VIDIOC_S_PRIORITY |
| |
| Sliced VBI control: |
| VIDIOC_G_SLICED_VBI_CAP |
| |
| The received video STD: |
| VIDIOC_QUERYSTD |
| |
| Streaming parameters: |
| VIDIOC_G_PARM |
| VIDIOC_S_PARM |
| |
| Output modulator (generally for TV): |
| VIDIOC_G_MODULATOR |
| VIDIOC_S_MODULATOR |
| |
| Those methods are brand new. Not yet used on drivers: |
| VIDIOC_ENUM_FRAMEINTERVALS |
| VIDIOC_ENUM_FRAMESIZES |
| |
| Overlay is somewhat legacy stuff those days: |
| VIDIOC_OVERLAY |
| VIDIOC_G_FBUF |
| VIDIOC_S_FBUF |
| |
| Those are unlikely to be implemented at API (legacy stuff, debug stuff or private): |
| VIDIOC_G_JPEGCOMP |
| VIDIOC_S_JPEGCOMP |
| VIDIOC_LOG_STATUS |
| VIDIOC_PRIVATE |
| VIDIOC_OVERLAY_OLD |
| VIDIOC_S_PARM_OLD |
| VIDIOC_S_CTRL_OLD |
| VIDIOC_G_AUDIO_OLD |
| VIDIOC_G_AUDOUT_OLD |
| VIDIOC_CROPCAP_OLD |
| |
| Also missing V4L1 mmap method: |
| VIDIOCGMBUF |
| |
| This method is interesting only to be used by driver-test to check |
| API compliance to the legacy method. |
