* vf_drawtext: Fix memory leakKieran Kunhya2017-03-21

* add signature filter for MPEG7 video signatureGerion Entrup2017-03-21
| | | | | | | | This filter does not implement all features of MPEG7. Missing features: - compression of signature files - work only on (cropped) parts of the video Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| * vf_scale_vaapi: Crop input surface to active regionMark Thompson2016-09-14
| | | | | | | | | | | | If the input has been decoded from a stream which uses edge cropping then the whole surface need not be valid. This defines an input region for the scaler so we only use the active area of the frame.

* | vf_hwupload: Add missing return value checkJun Zhao2017-03-12
| | | | | | | | | | | | | | | | | | | | | | Add missing return value checks to suppress build warning and remove noop ff_formats_unref() calling. Note: most filters using ff_formats_ref() didn't have a suitable error handling, it's a potential memory leak issue.

| | | | | | | | | | | | | | | | | | When setting the channel layout directly using AVBufferSrcParameters the channel layout was correctly set however the init function still expected the old string format to set the number of channels (when it hadn't already been specified).
