Seeking is not available during HLS stream playback

[ksmolyakov]

Hi. I'm looking for help troubleshooting issues with HLS stream playback in VLC.

We use nginx-rtmp-module to record HLS streams. It appears that seeking doesn't work when viewing the stream using VLC on different platforms (Windows, Android, iOS). The playback just stops when trying to go to the desired position. It seems that it depends on stream input, but it's not clear what exactly is wrong. Other players are able to seek just fine. I've tried Media Player Classic on Windows, MX Player on Android and HTML video tag element with hls.js. On the other hand, VLC is able to seek some HLS samples found on the internet.

Here is a sample HLS stream: http://hlstroubleshooting.s3-website-us-east-1.amazonaws.com/non-rewindable/index.m3u8
VLC is not able to seek this stream, but an HTML player on http://hlstroubleshooting.s3-website-us-east-1.amazonaws.com can.

Also the corresponding logs with "debug" level: https://pastebin.com/jiP9ZcFS

P.S. The sample is also uploaded here as a zip archive: https://gofile.io/?c=YUkjur
