Streaming is aborted on lost input signal #68

Open kunkku opened 5 years ago

kunkku commented 5 years ago

Video streaming is aborted when the input SDI signal is lost. Therefore, even a short anomaly in the signal can interrupt the streaming without the operator noticing. The expected behavior is to continue streaming automatically when the signal is restored.

Is it known yet at which component this fault is in? Like, (a) inside h264 encoder and its firmware, or (b) bmd-streamer binary, or (c) ffmpeg, or (d) in the backend?

bmd-streamer closes stdout and exits when the signal is lost, which also causes ffmpeg to exit. My understanding is that this is a feature, not a fault. As regards streaming, it would be possible to just restart these programs. Recording would require something more advanced to prevent ffmpeg from overwriting the video captured before the loss of signal.
