2007-10-12ivtv: fix incorrect EBUSY return.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Trying to open the radio when a capture is in progress will make it impossible to open the radio again since the radio stream wasn't released. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-25ivtv: VBI cleanups and fixesHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Besides some VBI cleanups this patch also fixes a subtle problem with the VBI re-insertion stream where the PIO work handler wasn't called quickly enough, resulting in occasional corrupt data. Furthermore the CC output didn't disable CC correctly and at the right time, causing duplicates to be sent. An saa7127 fix for VPS output was also added: the wrong data was sent. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-23ivtv: fix V4L2_ENC_CMD_STOP_AT_GOP_END supportHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Support for V4L2_ENC_CMD_STOP_AT_GOP_END was broken. While the driver correctly waited for the card to capture until the GOP was complete, afterwards the driver buffers were just flushed instead of waiting for the application to read all the pending data. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-23ivtv: fix VIDIOC_G_ENC_INDEX flag handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong frame types were filled in: the B and P frame types were swapped. This bug also hid a second bug: when a capture is stopped a last entry is written into the pgm index buffer with internal type 0, denoting the end of the program. This entry wasn't ignored, instead it was accidentally returned to the caller as a P frame. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-23ivtv: more cleanups, merged ivtv-audio.c and ivtv-video.c into ivtv-routing.cHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-23ivtv: header cleanupHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - add guards - remove unused header includes - move card-specific stuff from ivtv-driver.h to ivtv-cards.h - move YUV-specific stuff from ivtv-driver.h to ivtv-yuv.h Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-20ivtv: fix output mode processing: UDMA_YUV wasn't cleared.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - Always clear when stopping the decoder - Clear if the filehandle that is being close was used for UDMA_YUV output. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-19ivtv: move serialization to the fileops level.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Serialization is now done on the open/close/ioctl level and also when the read/write/poll start an encoder/decoder stream. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-19ivtv: improve debug messagesHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> - add FILE debug flag for open/close/read/write/poll. - show cmd for encoder/decoder command ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-18ivtv: fix udma yuv bugHans Verkuil
From: Ian Armstrong <ian@iarmst.demon.co.uk> Using udma yuv causes the driver becomes locked into that mode. This prevents use of the mpeg decoder & non-udma yuv output. This patch clears the operating mode when the device is closed. Signed-off-by: Ian Armstrong <ian@iarmst.demon.co.uk> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-07-28ivtv: always steal full frames if out of buffers.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When there are no more free buffers, then buffers are stolen from the predma queue. Buffers should be stolen from the head of that queue (which is where the most recently added buffers are) and all buffers belonging to a frame should be stolen. Otherwise 'half-frames' would remain in the queue, which leads to ugly playback and complete sync failure for YUV buffers. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-18ivtv: fix handling of INITIALIZE_INPUT fw callHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling, otherwise the computer can freeze or the top-third of the screen can start flickering. This patch ensures that CX2341X_ENC_INITIALIZE_INPUT is called at the right time and in the right way. In addition the stop capture handling was improved so that the last pending DMA transfer is also processed. Otherwise this would be the first data that arrived when a new capture was started which is not what you want. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-08-05ivtv: no need to mute the audio inputHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When changing channels the audio has to be muted. This is done by calling CX2341X_ENC_MUTE_AUDIO and by muted the audio input. The latter is not necessary and is now removed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-07-25ivtv-fb: initializing the framebuffer should trigger ivtv firmware loadHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-07-22ivtv, cx25840: postpone fw load until first use.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The firmware is now loaded when the driver is actually used for the first time. This allows the driver to be compiled in-kernel instead of as a module. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-07-22ivtv: fix TV-out VBI handling, only reset on last close.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> While decoding (MPEG or YUV) is active or when VBI output is in use, then do not clear the VBI output of the saa7127. Only after the last user is gone can we clear it. This fixes the case where playback was stopped, another channel was chosen and playback was restarted, while /dev/vbi16 was used to set the WSS (widescreen) setting. Without this fix the WSS was reset on every stop instead of just keeping the last value. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-07-22ivtv: fix pause/continue/play handlingHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Pausing a decoder followed by a Play command would do nothing. Fixed. Pausing a decoder running at non-standard speed following by a Continue would reset the speed to 100%. Fixed. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-02-27Fix comment style and set default debug level to 0Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Convert the '//' comments to kernel approved /* */ style comments. Set the default debug level to 0. As a result of which change some DEBUG_WARNs to errors or remove them altogether. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-02-26Add ivtv driver for the Conexant cx23416/cx23415 MPEG encoder/decoderHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> It took three core maintainers, over four years of work, eight new i2c modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac support from Axel Thimm, (hardware) support from Hauppauge, support and assistance from the v4l-dvb people and the many, many users of ivtv to finally make it possible to merge this driver into the kernel.
