mpegtspacketizer: Not enough information to calculate proper timestamp when playing radio stream
Hi,
I am on Debian 9.5 using GStreamer 1.10.4 and was trying to get the following radio stream URI to play:
http://kong.kbskme.gscdn.com/1fm/_definst_/1fm.stream/playlist.m3u8?_lsu_sa_=3c659434ccaf31a3e487c7ac3f91273d138c6da2308db4ff6d84653b703034a987d8defc35733864acfc38d5dcb24358235664fa74b665a0aa1808b70d504d61efebb17d2c38ff66efc58c0f860e1f43This is what the command line output is when using gst-launch-1.0 -v playbin3:
umagi@debian:~$ gst-launch-1.0 -v playbin3 uri=http://kong.kbskme.gscdn.com/1fm/_definst_/1fm.stream/playlist.m3u8?_lsu_sa_=3c659434ccaf31a3e487c7ac3f91273d138c6da2308db4ff6d84653b703034a987d8defc35733864acfc38d5dcb24358235664fa74b665a0aa1808b70d504d61efebb17d2c38ff66efc58c0f860e1f43

buffering... 0% But nothing happens. Since this kind of URI plays OK in VLC this does not seem to be a server-side issue.
Following the suggestions and help of Philippe Normand to my post on this issue on the GStreamer-devel mail list read post, I added the gst.log and the stream.ts capture file in attach.
The gst.log file shows a flurry of warnings of the kind:
0:00:00.287885677 6377 0x555e54214630 WARN mpegtspacketizer mpegtspacketizer.c:2331:mpegts_packetizer_pts_to_ts: Not enough information to calculate proper timestampCan you have a check? Thanks!
