This patch fixes the ENC_SEQ_RC_PARA initial delay and bitrate masks. These bit fields are 15 bit wide, not 7 bit. Signed-off-by:

The V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY_ENABLE control is a boolean but was documented as a integer. The documentation was also slightly miss-leading. Signed-off-by:

The decoder should handle V4L2_DEC_CMD_STOP to trigger drain, but it currently expecting V4L2_ENC_CMD_STOP. Signed-off-by:

Nicolas Dufresne authored
The MFC driver has two controls, DISPLAY_DELAY and DISPLAY_DELAY_ENABLE that allow forcing the decoder to return a decoded frame sooner regardless of the order. The added support for firmware version 6 and higher was not taking into account the DISPLAY_DELAY_ENABLE boolean. Instead it had a comment stating that DISPLAY_DELAY should be set to a negative value to disable it. This is not possible since the control range is from 0 to 65535. This feature was also supposed to be disabled by default in order to produce frames in display order. Signed-off-by:

These drivers haven't been tested in a long, long time. The hardware is ancient and hopelessly obsolete. These drivers also need to be converted to newer media frameworks but due to the lack of hardware that's going to be impossible. In addition, cheaper and vastly better hardware is available today. These drivers are already deprecated, so now remove them altogether. Signed-off-by:

These drivers haven't been tested in a long, long time. The hardware is ancient and hopelessly obsolete. These drivers also need to be converted to newer media frameworks but due to the lack of hardware that's going to be impossible. So these drivers are a prime candidate for removal. If someone is interested in working on these drivers to prevent their removal, then please contact the linux-media mailinglist. These drivers are already deprecated, so now remove them altogether.

This driver hasn't been tested in a long, long time. The company that made this chip has gone bust many years ago and hardware using this chip is next to impossible to find. This driver needs to be converted to newer media frameworks but due to the lack of hardware that's going to be impossible. Since cheap alternatives are easily available, there is little point in keeping this driver alive. This driver is already deprecated, so now remove it altogether. Signed-off-by:

All known old firmware firmware formats are downloaded using 8 byte chunks. Reject firmware if it could not be divided to 8 byte chunks and because of that we could simplify some calculations. Now both supported firmware download routines are rather similar. Cc: Olli Salonen <olli.salonen@iki.fi> Signed-off-by:

I found a problem on vc032x gspca usb webcam subdriver: "bytesperline" property is wrong for YUYV and YVYU formats. With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for pixel format conversion, the result is a wrong jerky image. Patch tested on my laptop (USB webcam Logitech Orbicam 046d:0892).

"n" is a user controlled integer. The code here doesn't handle the case where "n" is negative and this causes a static checker warning. drivers/media/usb/gspca/gspca.c:1571 vidioc_s_parm() warn: no lower bound on 'n' parm.capture.readbuffers is unsigned, so make n unsigned too, fixing this.

Add support in the PS3 Eye driver for QVGA capture at higher frame rates: 187, 150, and 137 FPS. This functionality is valuable because the PS3 Eye is popular for computer vision projects and no other camera in its price range supports such high frame rates. Correct a QVGA mode that was listed as 40 FPS. It is really 37 FPS (half of 75 FPS). Tests confirm that the nominal frame rates are achieved. Signed-off-by:

If start_streaming fails, then the buffers must be given back to vb2 with state QUEUED, not ERROR. Otherwise a WARN_ON will be generated. In the disconnect it is pointless to call pwc_cleanup_queued_bufs() as stop_streaming() will be called anyway. Signed-off-by:
