<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> </head> <body bgcolor="#ffffff" text="#000000"> Hi, I am trying to play multiple video files one after the other using GStreamer(vaapidecode and vaapisink plugins) and libVA-1.0.3. I am able to play one file successfully but once the first file is played to completion, we delete all references of the first pipeline and create a new one. When the second file is played, application crashes with the following error: libva: libva version 0.31.1 libva: va_getDriverName() returns 0 libva: Trying to open /opt/X11R7/lib/dri/i965_drv_video.so libva: va_openDriver() returns 0 libva: libva version 0.31.1 libva: va_getDriverName() returns 0 libva: Trying to open /opt/X11R7/lib/dri/i965_drv_video.so libva: va_openDriver() returns 0 VaapiApp: i965_media.c:277: i965_media_decode_picture: Assertion `media_state->media_states_setup' failed.
