> Please test current FFmpeg git head and provide an actual command line
that you tested and that produced a faulty stream together with the
complete, uncut console output to make this a valid ticket (works fine
here).
Tested again with current git. Doesn't work. While the command to create
an fmp4 stream seems to work fine and doesn't show any warnings or errors,
it is unreadable using http from a remote machine (or even localhost). It
is only readable with vlc and such other players that force a pixel
format. I think the issue might come from the init.mp4 file the command
creates with faulty pixel format info.
Here are the output of the commands:
Here is the command to make fmp4 hls stream, we will call it "the first
ffmpeg command" (no issues appear here. The input stream is a passthrough
ts stream I made from multicast. I tested on an external machine):

Check closely, the pixel format that is served from the fmp4 stream over
http is always '''none'''. VLC can play it because it forces the pixel
format.

The key line I believe is:
'''videotoolbox warning: forcing CVPX format: 420v'''
I couldn't find a way to force ffmpeg to specify a pixel format for the
input of the ffplay, ffprobe, or "the second ffmpeg" command.
Sorry for the long post I really dug deep into this and would love to help
solve it.
