All releases of v4l-utils and libv4l


Release Notes: Quirk support for forced tinyjpeg fallback has been added. A better luminance quantization table for Pixart JPEG has been introduced in tinyjpeg. Support for libjpeg >= v7 has been added. Software autowhitebalance now converges faster. JL2005BCD support has been improved. In libv4l, some more laptop models have been added to the upside-down devices table. A new matching algorithm for the upside-down table has been introduced. Several further enhancements and bugfixes have been made.


Release Notes: In v4l2-ctl, support was added for the new bitmask control type and for the control event, along with small bugfixes. qv4l2 gained support for bitmap controls. A new parser for dumps of em28xx with the drxk frontend was added. In libv4l, some more laptop models were added to the upside down devices table, support for the SE401 pixel format was implemented, and software autogain tweaks were made. Several other minor changes were made.


Release Notes: Various enhancements to libv4l were made, resulting in significantly less CPU usage with UVC HD cameras in several scenarios. An experimental library was added for associating video, audio, vbi, and other devices with each other, allowing apps, for example, to automatically figure out which ALSA input device carries the audio for a specific corresponding video device. Many more laptop models were added to the table of upside down devices. Support for the M420, Y10B, and JPGL pixel formats was added. The JPEG decompression code was rewritten for speed. Many further enhancements and fixes were made.


Release Notes: Many more laptop models were added to the upside down devices table. Support for an 8-bit grey format (V4L2_PIX_FMT_GREY) was added. libv4l1 can once again be compiled with newer Linux kernels. Various fixes were made to the utilities. Log parsers were added for cx231xx I2C, saa7134 PCI, sn9c201 USB, and generic USB.


Release Notes: Many more laptop models were added to the upside down devices table. Short frames are now detected, and up to three retries are initiated to get a non short frame. UVC cameras with more than 16 frame sizes are now properly supported. Support for the Xirlink C-It YYVYUY format and for the Konica YUV420 format were added. In the tools, various v4l-keytable improvements and various qv4l2 fixes were made, and v4l2-ctl gained support for s/g_dv_timings.


Release Notes: The new combination of v4l-utils and libv4l is now stable. Various v4l-keytable improvements, v4l2-ctl fixes, and qv4l2 fixes have been made. Many more laptop models have been added to the list of upside-down devices. Some minor bugfixes have been made.


Release Notes: This development release combines utilities from the v4l-dvb mercurial kernel as v4l-utils with the previous libv4l into a common distribution. v4l-keytable has been renamed to ir-keytable, and now better supports IR. libv4l adds several laptop models to the list of upside-down devices. Pixart JPEG markers removal was fixed. The whitebalance and gamma defaults of various sonixj and sonixb based cams were improved. Gamma correction is now enabled by default on pac7302 based cams. Convert errors in the first few frames of a stream are now ignored.


Release Notes: Support for decompressing CPIA1 compressed YUV was added, allowing this release to obsolete the old v4l1 cpia1 driver with the newer gspca driver. Support for mr97310a was improved. The autogain algorithm was made faster. More laptop models were added to the table of upside-down devices.


Release Notes: Four more laptop models were added to the table of upside-down devices. mr97310a decompression was improved. Support was added for decompressing yuv420 planar JPEG, which is required for w9968cf based cameras. Support was added for STV0680 raw bayer data. This helps to obsolete the w9968cf and stv680 v4l1 drivers.


Release Notes: 17 more laptop models were added to the table of upside-down devices. Better distinguishing between devices plugged into the same port was made possible. The software autogain algorithm was improved. Software whitebalance and autogain are now enabled for mr97310a cameras.
