Hi, <div> </div><div>i am using xine player for watching live TV. Xine runs TV playback by using the xine-lib-vaapi plugin provided at <a href="https://github.com/huceke/xine-lib-vaapi" target="_blank">https://github.com/huceke/xine-lib-vaapi</a>., branch vaapi-testing. When switching channels, I'am frequently (but not always) facing a kind of deadlock situation. The Player hangs and does not proceed. The system itself does not hang or stop in any way. When pressing a keyboard button or moving the mouse, the player proceeds immediately with TV stream rendering. </div> <div>When checking the log I figured out that the hanger happens around vaInitialize call from code fragment below. Are there any suggestions why this happens? Or what actions I might take to avoid this stupid bug. </div> <div>I'm testing on SNB system and I'm using libva and i965 from git/vaapi-ext branch and latest libcxb. I checked also with different kernels (3.2 and 3.3.) without success.</div><div> </div><div>Any help is appreciated</div> <div>Kurt</div> <div> </div><div> </div><div><pre style="padding-left:0px;padding-right:0px;line-height:1.4;padding-top:0px;color:rgb(51,51,51);font-size:12px;margin-bottom:0px;font-family:'Bitstream Vera Sans Mono','Courier New',monospace;margin-top:0px;padding-bottom:0px"> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em">static VAStatus vaapi_init_internal(vo_driver_t *this_gen, int va_profile, int width, int height, int softrender) {</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> vaapi_driver_t *this = (vaapi_driver_t *)this_gen;</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> ff_vaapi_context_t *va_context = this->va_context;</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> VAConfigAttrib va_attrib;</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> int maj, min, i;</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> VAStatus vaStatus;</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> vaapi_close(this_gen);</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> vaapi_init_va_context(this);</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> this->va_context->va_display = vaapi_get_display(this->display, this->opengl_render);</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> if(!this->va_context->va_display)</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> goto error;</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> vaStatus = vaInitialize(this->va_context->va_display, &maj, &min);</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> if(!vaapi_check_status((vo_driver_t *)this, vaStatus, "vaInitialize()"))</div> <div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:1em"> goto error;</div> </pre> </div>
