avcodec/prores_aw : add support for prores 444 with alpha
8 novembre 2018, par Martin Vignaliavcodec/prores_aw : add support for prores 444 with alpha
only 16b alpha is supported (not 8 bits)
following official encoder, alpha data doesn't impact
yuv plane quality.So the alpha data encoding is done after the yuv part.
It's also avoid to loose quality in yuv part when
alpha is not uniform.the alpha encoding funcs is mainly take from prores_ks

How to build ffmpeg as a Position independent executable (PIE) or PIC on Android ?
22 avril 2016, par Parth DoshiI have checked out the latest source of ffmpeg from the official website. I now want to compile and build ffmpeg as a position independent executable.
Here is what my configure command looks like
./configure --prefix=/usr/local --enable-gpl --enable-pic --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265
I have added the option
--enable-pic
to make it a PIE. However when the build process completes successfully and when I do a hardening check as follows then I get below outputhardening-check ffmpeg
ffmpeg:
Position Independent Executable: no, normal executable!
Stack protected: yes
Fortify Source functions: yes (some protected functions found)
Read-only relocations: yes
Immediate binding: no, not found!This tells me that ffmpeg is still not a PIE. Can anyone tell me what am I missing here ? Is there any other changes that need to be done for adding PIE support.
