appsrc not working with GST_APP_STREAM_TYPE_RANDOM_ACCESS

[Michael Yarochkin]

I was hopping to gain the speed during playback later.


(this topic is related to my another one http://gstreamer-devel.966125.n4.nabble.com/Speed-up-seek-td4680047.html)


As you can read here

https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-appsrc.html#GstAppStreamType


GST_APP_STREAM_TYPE_STREAM


No seeking is supported in the stream, such as a live stream.


GST_APP_STREAM_TYPE_SEEKABLE


The stream is seekable but seeking might not be very fast, such as data from a webserver.


GST_APP_STREAM_TYPE_RANDOM_ACCESS


The stream is seekable and seeking is fast, such as in a local file.

Yes, none of these elements work in pull mode, and RANDOM_ACCESS
doesn't really make sense here. What are you trying to achieve?
