* [media] coda: allocate bitstream buffer from REQBUFS, size depends on the formatPhilipp Zabel2015-04-10
| | | | | | | | | | | | | | | | | | | Allocating the bitstream buffer only when the format is set allows to guarantee that at least two frames fit into the bitstream buffer. For small frame sizes a smaller bitstream buffer can be allocated. Since the bitstream buffer size now depends on the format, replace CODA_MAX_FRAME_SIZE with ctx->bitstream.size where appropriate and remove the now unused constant. Since REQBUFS can be called multiple times, but the format can't be changed unless REQBUFS 0 was called before, we can just keep the allocated context and bitstream buffers if REQBUFS is called multiple times with a non-zero buffer count.

| * | [media] coda: add CODA7541 JPEG supportPhilipp Zabel2014-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds JPEG encoding and decoding support for CODA7541, using the BIT processor. Separate JPEG encoder and decoder video devices are created due to different streaming behaviour and different supported pixel formats. The hardware can not change subsampling on the fly, but encode and decode 4:2:2 subsampled JPEG images from and into this format. The CODA7541 JPEG decoder uses the bitstream buffer and thus can run without new buffers queued if there is a buffer in the bitstream. Since there is no standard way to store the colorspace used in JPEGs, and to make v4l2-compliance happy, the JPEG format always reports V4L2_COLORSPACE_JPEG.

| * | [media] coda: split out encoder control setup to specify controls per video ↵Philipp Zabel2014-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | device This patch splits the encoder specific controls out of the main control setup function. This way each video device registers only relevant controls.

| * | [media] coda: add coda_video_device descriptorsPhilipp Zabel2014-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Each video device descriptor determines the name, callback ops, and input and output formats on the corresponding video device. This simplifies coda_enum_fmt and coda_try_fmt a bit and will simplify adding separate video devices for JPEG codecs due to the slightly different behavior in the CodaDx6/CODA7542 case and a separate hardware unit on CODA960.
