This patch breaks most long lines, concatenates broken up text strings, and adds or removes parentheses where needed to make checkpatch happy. The long codec list lines and a few 81-wide lines remain. Signed-off-by:

Since we neither support composing on the OUTPUT side, nor cropping on the CAPTURE side, disable VIDIOC_CROPCAP and VIDIOC_G/S_CROP altogether. This silences a GStreamer warning when GStreamer tries to obtain the pixel aspect ratio using VIDIOC_CROPCAP. Signed-off-by:

This patch makes coda_s_fmt_vid_out propagate the output frame size to the capture side. The GStreamer v4l2videodec only ever calls S_FMT on the output side and then expects G_FMT on the capture side to return a valid format. Signed-off-by:

Lock modification of the timestamp list with bitstream_mutex and do not try to remove a timestamp element if the list is empty. This can happen if the userspace feeds us garbage or multiple encoded frames in a single buffer. Signed-off-by:

This patch increases the maximum vertical frame size reported by enum_fmt and accepted by try_fmt/s_fmt from 1080 to 1088. Since for 16x16-pixel macroblocks 1080p will be rounded up to this anyway, we may as well admit that we support it. Signed-off-by:

We know that it will return NULL in this case, so we can just as well skip it altogether. Signed-off-by:

Currently there is only the coda_h264_padding function, but we will have to add more H.264 specific helpers later. Signed-off-by:

This patch moves the context buffer allocation into the context start_streaming callbacks. The context buffer and internal framebuffer cleanup is moved into the context release callback. Signed-off-by:

Add a struct coda_context_ops that encapsulates context specific operations. This will simplify adding JPEG support in the future and helps to avoid exporting all functions individually when they move out of the main code file. Signed-off-by:

Userspace has a hard time making sense of format enumerations on V4L2 mem2mem devices if there are restrictions on which input and output formats can be used together. Alleviate the problem by splitting the video4linux device into separate encoder and decoder devices which list only raw formats on one side and only encoded formats on the other side. With this patch, the instance type (encoder or decoder) is already determined by the open file operation. Acked-by:

coda_fill_bitstream() calls v4l2_m2m_buf_done() which is no longer allowed before streaming was started. Delay coda_fill_bitstream() until coda_start_streaming() and explicitly set 'start_streaming_called' before calling coda_fill_bitstream() Signed-off-by:

When updating the crop rectangle during streaming, the IRQ handler will reprogram the resizer after the current frame. A race condition currently exists between the set selection operation and the IRQ handler: if the set selection operation is called twice in a row and the IRQ handler runs only during the second call, it could reprogram the hardware with partially updated values. Use a spinlock to protect against that. Signed-off-by:

The resizer_set_input_size() function prints a debugging message with the input width and height values. As the function is called from interrupt context, printing that message to the serial console could slow down the interrupt handler and cause it to miss the start of the next frame, causing image corruption. Fix this by reorganizing the resizer debug messages. The driver now prints the input size, the crop rectangle and the output size in the set selection handler instead of scattering debug messages in various places. Signed-off-by:

As the CCDC doesn't generate interrupts when stopped in BT.656 mode, restart it immediately when the next buffer after an underrun is queued instead of relying on the interrupt handler to restart the CCDC. Signed-off-by:

When the CCDC is already stopped due to a buffer underrun, the stop state machine won't advance in BT.656 mode as no interrupt are generated by the stopped CCDC in that mode. Handle this case explicitly in the ccdc_disable() function. Signed-off-by:

In BT.656 mode the synchronization signals are generated by the CCDC from the embedded sync codes. The VD0 and VD1 interrupts are thus only triggered when the CCDC is enabled, unlike external sync mode where the line counter runs even when the CCDC is stopped. We can't disable the CCDC at VD1 time, as no VD0 interrupt would be generated for a short frame, which would result in the CCDC being stopped and no VD interrupt generated anymore. The CCDC is stopped from the VD0 interrupt handler instead for BT.656. Signed-off-by:
