GStreamer record video with audio on Raspberry Pi

[hongyuanlu]

The recent work I am doing is to find a way to record video with audio using GStreamer on RPi. The following command worked with filesink using GStreamer 1.4, but after I update to 1.10.5 to use splitmuxsink, the following command does not work with splitmuxsink any more and throws error.

<code>

I am looking for any alternatives or changes to make this work, and hopefully it could bring others merits since Raspbian default Gstreamer is 1.4 and if you run those scripts online to install new Gstreamer, you might probably encounter the same problem if you want to use splitmuxsink on RPi.

Thank you in advance.

Ne need to add muxer in the pipline. Splitmuxsink will create/add muxer for given muxer object to splitmuxsink. Below pipeline should work for you.
