While not a required parameter, having it makes some -applications happy. - -bcm2835-codec is a little different from other decoder implementations -in that there is an intermediate format conversion between the hardware -and V4L2 buffers. The number of capture buffers required is therefore -independent of the stream and DPB etc. - -There are plans to remove the conversion, but it requires a fair amount -of rework within the firmware. Until that is done, simply return a value -of 1. - -Signed-off-by: Chen-Yu Tsai <wens@csie.org> ---- - .../vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c | 12 ++++++++++++ - 1 file changed, 12 insertions(+) - ---- a/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c -+++ b/drivers/staging/vc04_services/bcm2835-codec/bcm2835-v4l2-codec.c -@@ -2357,6 +2357,18 @@ static int bcm2835_codec_open(struct fil - } - ctx->fh.ctrl_handler = hdl; - v4l2_ctrl_handler_setup(hdl); -+ } else if (dev->role == DECODE) { -+ v4l2_ctrl_handler_init(hdl, 1); -+ -+ v4l2_ctrl_new_std(hdl, &bcm2835_codec_ctrl_ops, -+ V4L2_CID_MIN_BUFFERS_FOR_CAPTURE, -+ 1, 1, 1, 1); -+ if (hdl->error) { -+ rc = hdl->error; -+ goto free_ctrl_handler; -+ } -+ ctx->fh.ctrl_handler = hdl; -+ v4l2_ctrl_handler_setup(hdl); - } - - ctx->fh.m2m_ctx = v4l2_m2m_ctx_init(dev->m2m_dev, ctx, &queue_init); |
