Attached you could find a little SDL application to render the next pipeline using OpenGL. gst-launch-1.0 filesrc location=attract.avi ! avidemux ! vaapimpeg2dec ! glimagesink The application plays the video file in a loop and you can press ESC to abort playing. When the EOS is detected if the pipeline is set to GST_STATE_NULL I get: <div>X Error of failed request: BadDrawable (invalid Pixmap or Window parameter) Major opcode of failed request: 155 () Minor opcode of failed request: 8 Resource id in failed request: 0x420001e Serial number of failed request: 21 Current serial number in output stream: 75 </div> I've set some traces in the state-changed messages to see that going to PAUSE and READY is ok, but going to NULL there is some problem... <div>message: state-changed (glcolorbalance0) -- on_sync_message - glcolorbalance0 changed: PLAYING -> PAUSED message: state-changed (glcolorconvertelement0) -- on_sync_message - glcolorconvertelement0 changed: PLAYING -> PAUSED message: state-changed (gluploadelement0) -- on_sync_message - gluploadelement0 changed: PLAYING -> PAUSED message: state-changed (vaapidecode_mpeg2-0) -- on_sync_message - vaapidecode_mpeg2-0 changed: PLAYING -> PAUSED message: state-changed (avidemux0) -- on_sync_message - avidemux0 changed: PLAYING -> PAUSED message: state-changed (filesrc) -- on_sync_message - filesrc changed: PLAYING -> PAUSED message: state-changed (pipeline) -- on_sync_message - pipeline changed: PLAYING -> PAUSED message: state-changed (sink) -- on_sync_message - sink changed: PLAYING -> PAUSED message: state-changed (sink) -- on_sync_message - sink changed: PLAYING -> READY message: state-changed (glcolorbalance0) -- on_sync_message - glcolorbalance0 changed: PAUSED -> READY message: state-changed (glcolorconvertelement0) -- on_sync_message - glcolorconvertelement0 changed: PAUSED -> READY message: state-changed (gluploadelement0) -- on_sync_message - gluploadelement0 changed: PAUSED -> READY message: state-changed (glimagesinkbin0) -- on_sync_message - glimagesinkbin0 changed: PLAYING -> READY message: state-changed (vaapidecode_mpeg2-0) -- on_sync_message - vaapidecode_mpeg2-0 changed: PAUSED -> READY message: stream-status (sink) -- message: state-changed (avidemux0) -- on_sync_message - avidemux0 changed: PAUSED -> READY message: state-changed (filesrc) -- on_sync_message - filesrc changed: PAUSED -> READY message: state-changed (pipeline) -- on_sync_message - pipeline changed: PAUSED -> READY message: state-changed (sink) -- on_sync_message - sink changed: READY -> NULL message: state-changed (glcolorbalance0) -- on_sync_message - glcolorbalance0 changed: READY -> NULL message: state-changed (glcolorconvertelement0) -- on_sync_message - glcolorconvertelement0 changed: READY -> NULL message: state-changed (gluploadelement0) -- on_sync_message - gluploadelement0 changed: READY -> NULL message: state-changed (glimagesinkbin0) -- on_sync_message - glimagesinkbin0 changed: READY -> NULL message: state-changed (vaapidecode_mpeg2-0) -- on_sync_message - vaapidecode_mpeg2-0 changed: READY -> NULL message: state-changed (avidemux0) -- on_sync_message - avidemux0 changed: READY -> NULL message: state-changed (filesrc) -- on_sync_message - filesrc changed: READY -> NULL </div> Anybody can help me? I'm using gstreamer 1.12.2. I'm trying to develop a little video player using VAAPI, gstreamer and rendering in a OpenGL texture. Regards </div> </body> </html>
