This is not the right bug tracker to file bugs about GStreamer, this bug tracker is for git account requests only. Please file your bugs in bugzilla.gnome.org as per http://gstreamer.freedesktop.org/bugs/ (Didn't you file this there already?) Actually it's not the gstreamer's bug. It was caused by gstreamer-vaapi. A project based on libva to do hw decoding/encoding. I'm going to fix it. Created attachment 67068 [details] [review] EOS-flush patch to gstreamer-vaapi to flush end of stream buffers Created attachment 67069 [details] [review] decode residual bitstream for all codecs depends on 0001 patch. Fix core dump at end of video playing Please try attachment 67068 [details] [review] and 67069 to check whether this bugs was fixed. |

Environment: ------------ Service Arch (ia32/ia32e/IA64): AMD64 Guest Arch : AMD64 Guest OS Type : Linux Hardware: SandyBridge gstreamer: # pkg-config --modversion gstreamer-0.10 0.10.36.1 gstreamer-vaapi: commit 0b3d75f14b4a275d13eefadc81ff7e1734d2fd0f libva: commit 376075a6e6ffa9eb0e8d3c99c298fca6332095a0 intel-driver: commit 560ab2c9b116ddaddd90c24f520c4dc66310c9e7 we used mplayer on the same driver to decode, there isn't any lost frames. Bug detailed description: -------------------------- I found that one or more frames lost while playing mp4 files using gstreamer. we add "printf(" %s, %s, %d\n", __FILE__, __FUNCTION__, __LINE__)" in the function "vaPutSurface", then play a 50-frames MP4 file with gst-launch, and there are 49 vaPutSurface print in log, so it seems gstreamer lost 1 frame. if playing raw video files, gstreamer lost more frames, about 15 frames. Reproduce steps: ---------------- 1.# xinit& 2.# gst-launch-0.10 playbin2 uri=file:///file.mp4
