This terms is met in many places of the GStreamer documentation, but I can't find its strict definition.
So, what is it, exactly? Or, please, point to the definition. |

Any thread not created by the application, but by GStreamer. Often used as 'streaming thread' (in which dataflow happens) vs. 'application thread' (in which things like property setting/getting is usually done, and state changes). There are usually multiple streaming threads in a typical GStreamer pipeline. For application writers it rarely matters which one it is exactly though, just that it's a different thread than the main application's thread.

Hi Tim,
Just a small cross question on this: How one can control these no. of threads creation on a single pipeline ? or if I put it in another way, how these threads get created in gstreamer ? e.g. does it depend on the no. of "elements" in a single pipeline or some other factor matters.

This is covered in the docs. http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/chapter-threads.html http://cgit.freedesktop.org/gstreamer/gstreamer/tree/docs/design/part-messages.txt - GST_MESSAGE_STREAM_STATUS |

Thanks.
Also, do the terms 'streaming thread' and 'streaming task' have the same meaning?

Hi,
After reading the doc on the thread (few weeks ago) I still had a question on multithreading for which I did not found the answer in the doc. Does some plugin have their own multithreading capability ? My interest is for the x264 encoder. Multithreading of the h264 encoding process is a mandatory thing as soon as you do live encoding. If anybody knows about this... Regards, Timothe On Thu, Jan 13, 2011 at 11:54 AM, wl2776 <[hidden email]> wrote:

It depends on the plugin. For example, mpeg2 PS demuxer has. You could search the source code for GstTask or GThread. |

This is done at the x264 library level and hidden from both GStreamer and the application (but configurable of course, see gst-inspect x264enc).
