upgrade ffmpeg from ff3.4--ijk0.8.7--20180103--001 to to FFmpeg4.4(which is latest FFmpeg release)

How to upgrade

pls attention following files:

Only in android/contrib/ffmpeg-x86/libavutil: dns_cache.c Only in android/contrib/ffmpeg-x86/libavutil: dns_cache.h Only in android/contrib/ffmpeg-x86/libavformat: ijkutils.c Only in android/contrib/ffmpeg-x86/libavutil: application.c Only in android/contrib/ffmpeg-x86/libavutil: application.h

diff android/contrib/ffmpeg-x86/libavutil/Makefile /tmp/ffmpeg-x86/libavutil/Makefile diff android/contrib/ffmpeg-x86/libavformat/Makefile /tmp/ffmpeg-x86/libavformat/Makefile diff android/contrib/ffmpeg-x86/libavformat/http.c /tmp/ffmpeg-x86/libavformat/http.c diff android/contrib/ffmpeg-x86/libavformat/tcp.c /tmp/ffmpeg-x86/libavformat/tcp.c diff android/contrib/ffmpeg-x86/libavformat/protocols.c /tmp/ffmpeg-x86/libavformat/protocols.c

modify ijkmedia/ijkplayer/ijkavformat/allformats.c

comment following line in ijkmedia/ijkplayer/ijkavformat/allformats.c

IJK_REGISTER_PROTOCOL(async);

there is conflict between ijkimp_ff_async_protocol and ff_asyncprotocol，it will bring segment fault when memcpy(&ff##x##_protocol, protocol, protocol_size) (which located in libavformat/ijkutils.c) was called

Defect

Android NDK r14b is required for target Android but no official technical support is provided in the future

不客气，这个分支在原始的ijkplayer 0.8.8上做了一些 bugfix与功能增强https://github.com/zhouwg/kantv/blob/dev-baseon-latest-k0.8.8/NEWS.md，希望对开源社区有点用
