Hi Christian,

The new patch leads to seg fault on my system. You forgot to set the
needs_begin_frame to true when the decoder is created. Here's diff for
reference:
--------------------------------
diff --git a/src/gallium/state_trackers/va/picture.c
b/src/gallium/state_trackers/va/picture.c
index e75006d..a51e482 100644
--- a/src/gallium/state_trackers/va/picture.c
+++ b/src/gallium/state_trackers/va/picture.c
@@ -178,6 +178,8 @@ handlePictureParameterBuffer(vlVaDriver *drv,
vlVaContext *context, vlVaBuffer *

       if (!context->decoder)
          return VA_STATUS_ERROR_ALLOCATION_FAILED;
+
+      context->needs_begin_frame = false;
    }

    return vaStatus;
----------------------------------

I am wondering if calling decode_bitstream one at a time for each
buffer is similar to
calling it with all buffers at once?

Cheers,
Nayan
