According to the doc, V4L2_BUF_FLAG_DONE is cleared after DQBUF: V4L2_BUF_FLAG_DONE 0x00000004 ... After calling the VIDIOC_QBUF or VIDIOC_DQBUF it is always cleared ... Unfortunately, it seems that videobuf2 keeps it set after DQBUF. This can be tested with vivid and dev_debug: [257604.338082] video1: VIDIOC_DQBUF: 71:33:25.00260479 index=3, type=vid-cap, flags=0x00002004, field=none, sequence=163, memory=userptr, bytesused=460800, offset/userptr=0x344b000, length=460800 This patch forces FLAG_DONE to 0 after calling DQBUF.
