Old description:
> Summary of the bug:
>
> I am creating an HLS stream with two resolutions using NVIDIA x264
> hardware encoder and FFmpeg is generating a segment with 0 bytes length
> after init segment in each video child playlist. An example of a child
> playlist is given below.
> How to reproduce:

New description:
Summary of the bug:
I am creating an HLS stream with two resolutions using NVIDIA x264
hardware encoder and FFmpeg is generating a segment with 0 bytes length
after init segment in each video child playlist. An example of a child
playlist is given below.
How to reproduce:
