gstreamer last frame

hi, i`m trying to implement a pipeline using playbin and then when it receives a EOS message prepares another uri to play, but when i use this code: gst_element_set_state(data->pipeline, GST_STATE_READY); g_object_set(data->playbin, "uri", nexItem, NULL); gst_element_set_state(data->pipeline, GST_STATE_PLAYING); i lose the last frame rendered. Is there a way to keep the last frame until i finish preparing the next file?

You could use the about-to-finish signal to set the next URI, instead of resetting the pipeline.

yes, i`m using the about-to-finish signal right now... but i would like to use the EOS message as well as manually send a next command to the pipeline... and every time i do that i get a black frame when i use gst_element_set_state(data->pipeline, GST_STATE_READY); 2018-04-25 21:26 GMT-03:00 Nicolas Dufresne <[hidden email]>:

Though, have you tried, after reaching EOS, so set the new URI, and send a flushing seek to position 0 ? Never tried myself. > > 2018-04-25 21:26 GMT-03:00 Nicolas Dufresne <[hidden email]>: > > > > Le mer. 25 avr. 2018 15:27, Robson Ferreira <[hidden email] > > v> a écrit : > > > hi, > > > > > > i`m trying to implement a pipeline using playbin and then when it > > > receives a EOS message prepares another uri to play, but when i > > > use this code: > > > > > > gst_element_set_state(data->pipeline, GST_STATE_READY); > > > g_object_set(data->playbin, "uri", nexItem, NULL); > > > gst_element_set_state(data->pipeline, GST_STATE_PLAYING); > > > > > > i lose the last frame rendered.
