Hi, sorry for the late reply, too much time spent for the MeeGo conference. <div class="gmail_quote">On Thu, Nov 11, 2010 at 3:43 PM, TTGator <<a href="mailto:asorgius@gmail.com">asorgius@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> I am experiencing some gst-launch lockups from time to time. I will try to give a quick overview of the issue in case someone may know something about this, and I can provide more detail if needed. Basically, it seems like there may be a race condition with EOS and SIGUSR2. When the SIGUSR2 signal is delivered to a pipeline that was transitioning due to EOS, I see the indication that the SIGUSR2 was caught, but no further info regarding taking the pipeline to NULL. </blockquote><div> Usually when an EOS occurs the pipeline state goes to READY (if you want to bring it to NULL, you need to do it i.e. in your bus callback). </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> After this occurs, a reboot of the system is required to run a new pipeline. </blockquote><div> This is pretty strange, most likely due to the HW-specific elements you're using (either dmaidec_h264 or omapsink). I suggest you to check your dmesg output and your BSP manual to know what's happening and how to restore functionality without a reboot. Are you sure even hw independent pipelines of the like of: gst-launch audiotestsrc ! fakesink -v are not working?
