So far so good. Duration is correct. Don't know why it says "start: 10.000000", because the hls videostream starts from the beginning.

The next commit however causes the following:

Now the hls videostream has no detected duration, but above all starts at 49:00.00 and thus only has a 02:18.00 duration!

Note: this hls videostream could be geoblocked for foreigners.

comment:2 by CoRoNe, 7 years ago

Locally reverting mentioned commit solves the issue. But I don't know the importance of this commit, because this change was obviously committed for a reason.

comment:5 by CoRoNe, 7 years ago

That's probably because:

Note: this hls videostream could be geoblocked for foreigners.

Working fine over here.

comment:6 by Aman, 7 years ago

It appears like this server does not react well to Range requests, returning conflicting sizes as part of the 206 response:

< Content-Length: 11069
< Content-Range: bytes 0-10588/10589

The size of the data returned is 11069, even though the range says otherwise.

The hls demuxer sets seekable=0 on outgoing requests already to avoid problems like this. However, this option does not get set on the initial m3u8 url which is opened before the hls demuxer is invoked.

A workaround is to pass "-seekable 1" or "-seekable 0" yourself, which will endure the entire playlist is downloaded and it doesn't get mistaken for a live playlist (which is missing an ENDLIST tag).

comment:7 by CoRoNe, 7 years ago

"tmm1" and I have already had a private e-mail conversation about this and -seekable 0 was (and is) indeed a fix/workaround in this case. Thanks again.
Sorry for the late reply. This ticket can be closed.
