Use of -hls_flags iframes_only results in incorrect EXT-X-VERSION value

Bruce Roberts
Hello,

I'm trying to generate Apple mediastreamvalidator compliant HLS using
ffmpeg and have very nearly achieved that.

The only remaining problem is that use of " -hls_flags iframes_only"
correctly adds the #EXT-X-I-FRAMES-ONLY tag to my trickplay m3u8 but it
doesn't increment the #EXT-X-VERSION value from 3 to 4.

The validator then complains as follows:

--------------------------------------------------------------------------------

MUST fix issues

--------------------------------------------------------------------------------



Error: incorrect version number for feature

--> Detail:  Line: (null)

--> Source:  output_TrickPlay_Video_8bit.m3u8

If I manually edit the file and change the version value to 4, validation
is successful.

I have upgraded ffmpeg to the latest version but the problem remains.

Is there a way for me to force #EXT-X-VERSION:4 ?

Here is my command and the console output:

Current implementation of I-FRAMES-ONLY is very limited.
