Merge commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a'
11 mai 2017, par James AlmerMerge commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a'
* commit '1202b712690c14f0efb06e4ad8b06c5b3df6822a' :
theora : export cropping information instead of handling it internally
h264dec : export cropping information instead of handling it internally
h264dec : be more explicit in handling container cropping
hevcdec : export cropping information instead of handling it internallyThis commit is a noop.
This changes the cropping behavior, when it's supposedly only meant to move
it outside of the decoder.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2017-May/211239.html for the
discussion about it.Merged-by : James Almer <jamrial@gmail.com>

it seems to apply transcode (decode & encode again) to the output implicitely ?
