[Libva] CBR encoding fails

[Artem Makhutov]

Hello,

I am trying to do CBR encoding of a video.

I am using lates git master of libva and libva-intel-drivers.

Before commit "745340dd013399f64507de73401ab3adb712dad5 in intel-drivers (Encoding: Use the different delimeter to pass packed_rawdata and slice_header based on VAConfigAttribEncPackedHeaders attribute)" it just segfaults in intel_mfc_brc_prepare.
After this commit I am getting this:

h264encode -w 1920 -h 1080 --srcyuv /tmp/123.yuv -f 25 -n 0 --rcmode CBR --bitrate 8500000
Source YUV file /tmp/123.yuv with 1376 frames
Source frame is 1920x1080 and will code clip to 1920x1088 with crop

WARNING: packed slice_header data is missing for some slice under packed SLICE_HEADER mode
encode_frames:vaEndPicture (2013) failed,exit

Also any stable releases segfaults when trying to encode CBR.

Any chance to fix it?

Thanks, Artem
