(Fixes: libav/672, Closes: #741240, LP: #1288206)
- rtmpproto: Make sure to pass on the error code if read_connect failed
- lavr: allocate the resampling buffer with a positive size

- movenc: allow override of "writing application" tag
- matroskaenc: allow override of "writing application" tag
- avfilter: Add missing emms_c when needed
- build: Use pkg-config for openjpeg (Fixes: libav/387)
- mpeg12: check scantable indices in all decode_block functions
- sgidec: fix buffer size check in expand_rle_row()
- adx: check that the offset is not negative
- mpegvideo: set reference/pict_type on generated reference frames
- h264: Fix various crashes found in samples pointed by Mateusz
"j00ru" Jurczyk and Gynvael Coldwind - Thanks!
* Rebuild is reported to fix vaapi, Closes: #745655
* Fix invocation of dpkg-maintscript helper, LP: #1315672
* cleanup leftovers of the former libav-source package
* Simplify listing packages with dh_listpackage
* Drop transitional arch:all -extra- packages
* Bump standards version to 3.9.5, no changes needed
libav (6:9.11-4) unstable; urgency=medium
* Imported Upstream version 9.11
- bumped severity because of many security relevant changes
- update freetype header detection
libav (6:9.11-3) unstable; urgency=low
* Add upstream patch to enable PIC on s390(x), Closes: #726733
libav (6:9.11-2ubuntu3) utopic; urgency=high
* No change rebuild against librtmp1.
