Hello, we have an omap based intelligent camera and image sensor is connected to camera parallel interface. Image capturing via "CCDC output" works fine. When streaming is on and reading "sequence" variable, it shows always -1. Looking at kernel-source ispvideo.c, i found following if-else statement: /* Do frame number propagation only if this is the output video node. * Frame number either comes from the CSI receivers or it gets * incremented here if H3A is not active. * Note: There is no guarantee that the output buffer will finish * first, so the input number might lag behind by 1 in some cases. */ if (video == pipe->output && !pipe->do_propagation) buf->vbuf.sequence = atomic_inc_return(&pipe->frame_number); else buf->vbuf.sequence = atomic_read(&pipe->frame_number); When i change to if (video == pipe->output && pipe->do_propagation) ... the sequence variable is incremented. So my question: Could it be that "pipe->do_propagation" should be tested on true and not on false? If this change is wrong, how can i achieve that the sequence number is incremented?
