I found that commit but it didn't fix or cause the problem on master?!

So on branch 3.1
This commit 309fa24f361f1c9d357f8d152c3b78718d2f870d
- Fixes seeking
- Breaks frame counts

On master this commit 9884f17e343b37aef442fafa05bd0113cdf47087, which
should be the same
- Seeking stays broken (it was broken the commit before too)
- Doesn't change frame count (it was also working the commit before)

(I also tested the one before and after to no avail)

I've searched master but can't find a commit on which seeking works as
expected.

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.

Same steps with the master's version of these commit will always yield the
wrong frame.

Any ideas?
