The BIT encoder does not use a per-context bitstream ringbuffer as it encodes directly into the videobuf2 capture queue's buffers. Avoid allocation of the bitstream ringbuffer for encoder contexts. Signed-off-by:

Make sure the buffer_mutex lock is taken in coda_bit_release while coda_free_framebuffers and coda_free_context_buffers are called. Signed-off-by:

In preparation for CODA9 JPEG support, which doesn't have to call SEQ_END on the BIT processor. Signed-off-by:

Since we have to copy from input buffers into the bitstream ringbuffer with the CPU, there is no need for contiguous DMA buffers on the decoder input side. Signed-off-by:

Call coda_estimate_sizeimage from both try_fmt and set_defaults to avoid this v4l2-compliance warning on the h.264 decoder video device: G_FMT: 1920x1088, 32315559, 1, 1920, 1048576, 3, 0, 0, feedcafe TRY/S_FMT: 1920x1088, 32315559, 1, 1920, 3133440, 3, 0, 0, feedcafe fail: v4l2-test-formats.cpp(948): Video Capture: S_FMT(G_FMT) != G_FMT Signed-off-by: -

On i.MX6, two subsampling ping-pong buffers are used for motion estimation and deblocking They should not be counted as framebuffers, or they will be also used to store reconstructed frames, causing visible artifacts in P-frames. Signed-off-by:

This patch queues seq_end_work and flushes the queue during stop_streaming and clears the ctx->initialized flag. This allows to start streaming again after stopping streaming without releasing the context. Signed-off-by:

The isequence counter is never used, qsequence counts the buffers queued into the bit decoder bitstream ringbuffer. It needs to be reset in stop_streaming. Signed-off-by:

To make sure a set RET_DEC_PIC_SUCCESS flag is not a leftover from a previous successful run, clear it in prepare_decode. Signed-off-by:

v4l2-compliance complains about invalid colorspace settings being accepted on the output side. This patch only allows REC709 and JPEG. Signed-off-by:

Philipp Zabel authored
Clarify whether job_ready returns false because the context is on hold, waiting for new input buffers, whether there are not enough input buffers to fill two into the bitstream, or whether there is not enough data in the bitstream buffer for the bitstream reader hardware to read a whole frame.

If userspace doesn't properly separate the bitstream input into individual frames (which may happen for example on slightly corrupted streams) the CODA hardware may decode more frames than we expect. We already log an error in this case, but it's also necessary to adjust the sequence offset. Otherwise we spam the log with a sequence number mismatch on every frame frame after the unexpected one.

Handle an empty buffer metadata list without crashing. This can happen if the decoder is fed a broken stream, or multiple compressed frames in a single queued buffer. Signed-off-by:

Do not remove the per-context debugfs directory before the per-buffer debugfs entries contained therein. 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:

Hans Verkuil authored
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:
