Hi, I was testing with the linux-next kernel + the v2 patches HW: odroid xu4 decoding (working): tested with gstreamer encoding: tested with gstreamer && mfc-patched ffmpeg before patches: encoding worked after patches: encoding didn’t work.
I moved on from linux-next in the meantime and I cannot give you logs, BUT I’ve seen Hardkernel applied these patches (and all the linux-next MFC patches) on top of their 4.9 tree, and the result is very similar to mine on linux-next: https://github.com/hardkernel/linux/issues/284 Mar 21 13:04:54 odroid kernel: [ 37.165153] s5p_mfc_alloc_priv_buf:78: Allocating private buffer of size 23243744 failed Mar 21 13:04:54 odroid kernel: [ 37.171865] s5p_mfc_alloc_codec_buffers_v6:244: Failed to allocate Bank1 memory Mar 21 13:04:54 odroid kernel: [ 37.179143] vidioc_reqbufs:1174: Failed to allocate encoding buffers A user reported even adding s5p_mfc.mem=64M did not make the encoder work.
