gstreamer seeking

Hello,

I'm currently using the gstreamer 0.10 plugins for the 3.0.35 OS version. I want to play just a part of a video i.e from second 10 to 20, which I do by using a gst_element_seek(). According to the gstreamer documentation, the demuxer is supposed to send an SEGMENT_DONE signal after the segment is done, however what is happening is that my video is starting at the tenth second and playing until the end. Can I play only a part of the video using aiurdemux?

I looked at the src code for the demuxer (deb-pkg_gstreamer-imx-0.10/aiurdemux.c at master · mxOBS/deb-pkg_gstreamer-imx-0.10 · GitHub ) and didn't found anything about a SEGMENT_DONE message.

Here is how I'm setting my seek:

gst_element_seek( p->m_elements.pipeline,
                                1.0,
                                GST_FORMAT_TIME,
                                (GstSeekFlags)(GST_SEEK_FLAG_FLUSH | GST_SEEK_FLAG_SEGMENT),
                                GST_SEEK_TYPE_SET,
                                10,
                                GST_SEEK_TYPE_SET,
                                20);

Thank you,

Erick.

Hi Jesus

gstreamer 0.10 is very old version and not more supported, recommended to

use gstreamer 1.0, its usage is described in Linux documentation found on

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6series-i.mx-7series-software-and-development-tool-resources:IMX_SW

gstreamer-imx issues can be posted on

Issues · Freescale/gstreamer-imx · GitHub

Best regards
igor
