EOS in gstreamer DM385

Rajesh Kannan

Hello Margarita,

I'm working MP4 Playback using GStreamer in EZSDK

In bus_call function after getting End-Of-Stream, Is it possible to change the state of pipeline ?

Here I'm not using the g_main_loop_quit API, without using this API , After EOS I want to set the state of pipeline NULL and unrefer

gst_element_set_state (pipeline, GST_STATE_NULL);
gst_object_unref (GST_OBJECT (pipeline));

If it is not possible any other idea to implement this ?

Hello,
gst_element_set_state( pipeline, GST_STATE_NULL );
if( pipeline != NULL )
poll_for_state_change( GST_STATE_NULL, pipeline );
if( pipeline != NULL ) {
gst_object_unref( pipeline );
pipeline = NULL;

Best Regards,
Margarita

Hello Margarita,

In bus_call handler I'm checking and getting the messages by using gst_bus_timed_pop(bus, 100 * GST_MSECOND); this API. It is periodically checked by do-while loop... upto End-Of-Stream.

Why because I'm using this bus API , After EOS, I'm able to play another video without interrupt

In this case I want to pause and resume and stop the streams by another process using switch case !!! here is not allow to perform these kind of activities ?

How to overcome ? And share me idea to implement ?

I am not sure what you mean. Are you asking when the application is in playing state you to be able to pause-resume, stop the current video?
If yes, this is possible.

Is possible.. but periodically do-while loop is running.. In between I'm trying to PAUSE or stop here...
do
{
MSG = gst_bus_timed_pop(bus, 100 * GST_MSECOND);
if(MSG)
{
printf("Gst MEssage is = %s\n",GST_OBJECT_NAME (MSG->src));
if( ( bus_call ( MSG ) ) != TRUE )
{
printf("process_handler failed\n") ;
break ;
}
}

}while( eos_state == FALSE ) ;

I have one more function to select the use case to pause or resume like that...
In between is allow to pause ?

Hello,

I am not very sure that you can. You could try. What you are trying to archive?
Have you check element like selector-input?
You could try also to dynamically unlink the filesrc locations and point different file in the application.

Hello Margarita,

I tried and achieved to play another video after end-of-stream reached in the first file.

Here after EOS I'm using

const char *cache_clear="echo 3 > /proc/sys/vm/drop_caches"; this system command to clear the cache memory

What it will do ? How it's working to clear the cache memory ?

Hello,

I have few questions in order to help you.

You are playing one video file with gst application right?
After the EOS of the first video, you destroying the pipeline move it to NULL state and etc. The application is closed. Then you want to execute this application again to play the different video file, correct?

Margarita

Hello Margarita,

That command related to kernel level.. After unreferred, able to play next file, no issue

Thanks & Regards,
