rtmpsink

[Mike Chong]

The following pipeline was working for me:gst-launch videotestsrc ! queue ! x264enc ! flvmux name=muxer ! rtmpsink location='rtmp://<streaming_url>' audiotestsrc ! queue ! audioconvert ! muxer.
However, a similar pipeline was not working within our application.
We discovered that the issue was we were using a tee, and splitting the pipeline to x264enc, and another bin that included an ffmpegcolourspace, and an autovideosink (something I had overlooked...).  The issue we were encountering was described here.
We found that we could resolve the issue bya) making the queue in the other output bin (before the ffmpegcolourspace and autovideosink) leaky (as described in the above link) orb) setting tune=zerolatency.  I'm not sure which of the magics the zerolatency tuning uses fixes the problem, but to say something wrong in the hopes of being corrected, I would guess that one of the zerolatency settings stop x264enc from taking its time and prevent buffers from being filled up (please correct me, I'm curious).
Cheers,
Mike
