failed transcode not reported as failed recording
I mistakenly compiled x264 with 10bit support, and transcoding upon recording failed (should I open another issue about that?).
The transcoding fails with "libav : Specified pixel format yuv420p is invalid or not supported" in the log. The resulting recording contains only audio (is an mka file).
IMO it should be reported as failed, since sound without video is quite useless on a tv show...
