+Subject: avcodec/rkmpp : Fix broken build due to missing control operation
+X-Git-Url: http://git.videolan.org/?p=ffmpeg.git;a=commitdiff_plain;h=c6f84106366c6f243a8b07dbffcc7880009aa904
+
+avcodec/rkmpp : Fix broken build due to missing control operation
+
+This patch is taking care of https://trac.ffmpeg.org/ticket/6834.
+It seems that one of the control operations that was available to get
+the free decoders input slots was removed.
+
+There is another control operation to retrieve the used slots. Given
+that the input slot count is hardcoded to 4 in mpp at this point,
+replacing the old control operation by the other one.
+
+This was tested on Rockchip ROCK64.
