Yup I posted that earlier in the thread.
https://s3.amazonaws.com/slffmpegdebug/seekProb/seekProb.m3u8
It's publicly accessible


---> From that earlier post
I shared the video on S3 so if you want to check it out from the 3.1 branch
git checkout 309fa24f361
make clean ; make distclean ; ./configure --enable-gpl --enable-libx264
--enable-nonfree --enable-libfdk-aac --enable-openssl --enable-static &&
make -j5
rm -f dude.png ; ./ffmpeg -y -ss 0 -loglevel error -vsync 0 -i
https://s3.amazonaws.com/slffmpegdebug/seekProb/seekProb.m3u8 -f image2
-q:v 1 -vframes 1  dude.png ; feh dude.png

this will show you the same frame as (notice no -ss 0)
rm -f dude.png ; ./ffmpeg -y -loglevel error -vsync 0 -i
https://s3.amazonaws.com/slffmpegdebug/seekProb/seekProb.m3u8 -f image2
-q:v 1 -vframes 1  dude.png ; feh dude.png

Then
git checkout 3586c6868
make clean ; make distclean ; ./configure --enable-gpl --enable-libx264
--enable-nonfree --enable-libfdk-aac --enable-openssl --enable-static &&
make -j5
rm -f dude.png ; ./ffmpeg -y -ss 0 -loglevel error -vsync 0 -i
https://s3.amazonaws.com/slffmpegdebug/seekProb/seekProb.m3u8 -f image2
-q:v 1 -vframes 1  dude.png ; feh dude.png

Will show you the wrong frame.
