Set EXT-X-ENDLIST tag in HLS playlist

[joakim]

Hi,
I'm developing a c application with the following pipeline:
rtspsrc->queue->rtph264depay->h264parse->mpegtsmux->hlssink

Iv've managed to get everything to work as expected except one thing. When I
manually stop the pipeline from playing state to null state like this:

void *
gst_main_loop(void *loop)
{
    g_main_loop_run(loop);
    return 0;
}

int
rtsp_client_stop_stream(rtsp_client_t *rtsp_client) {
    gst_element_set_state (rtsp_client->pipeline, GST_STATE_NULL);
    g_main_loop_unref(rtsp_client->loop);
    pthread_join(*(rtsp_client->pthread), NULL); //free the pointer
    gst_object_unref (GST_OBJECT (rtsp_client->pipeline));
    rtsp_client->pthread = NULL;
    rtsp_client->loop = NULL;
    rtsp_client->pipeline = NULL;
    return 0;
}

The stream stops but the EXT-X-ENDLIST tag in the hls playlist file is not
set. I'm I doing something wrong which results in this tag not being set?

I guess you should push an EOS event to your pipeline and wait for the
matching EOS message on the bus.

You were right about pushing an EOS event to the pipeline. I just added one
line to my stop function and then it worked:

int
rtsp_client_stop_stream(rtsp_client_t *rtsp_client) {
    gst_element_send_event(rtsp_client->sink, gst_event_new_eos());
    gst_element_set_state (rtsp_client->pipeline, GST_STATE_NULL);
    FILE *fp = NULL;
    fp = fopen(rtsp_client->playlist_path, "r");
    g_main_loop_unref(rtsp_client->loop);
    pthread_join(*(rtsp_client->pthread), NULL); //free the pointer
    gst_object_unref (GST_OBJECT (rtsp_client->pipeline));
    rtsp_client->pthread = NULL;
    rtsp_client->loop = NULL;
    rtsp_client->pipeline = NULL;
    return 0;
}

Thank you for the answer!
