Hi all,
Who can tell me why the following code segment in gstqueue2.c is needed? When I use queue2 for local playback, it's OK to seek forward/rewind. But When I use queue2 for network playback, such as progressive download, I meet a problem, it will block at line 1547 if seeking to the position where data hasn't been downloaded yet. I expect it to return immediately, not block. 1543 GST_QUEUE_MUTEX_LOCK (queue); 1544 /* we have to wait until the upstream element is at least paused, which 1545 * happened when we received a first item. */ 1546 while (gst_queue_is_empty (queue)) { 1547 GST_QUEUE_WAIT_ADD_CHECK (queue, flushing); 1548 } 1549 GST_QUEUE_MUTEX_UNLOCK (queue); Best Regards Wang Xuefeng ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
