GNOME Bugzilla – Bug 622809
[tsdemux] ATSC mpeg-TS video stream cannot be played by totem
Last modified: 2015-10-13 10:35:23 UTC
Sample: http://launchpadlibrarian.net/50954756/foo.mpeg Created using mplayer dvb://SRC-HD -cache 2000 -dumpstream -dumpfile "/tmp/foo.mpeg" It seems mplayer is currently the only application able to play over-the-air HD ATSC video content. Totem doesn't do anything when trying to open those files, but it would be really nice if it worked. Hoping this sample file can be useful.
ffdemux_mpegts plays it fine. Bug in mpegtsdemux.
The sample doesn't contain a PMT for the one reported program in the PAT. So not strictly speaking a bug but more a missing feature in mpegtsdemux. Probably a bug in mplayer that it doesn't dumps the PMT.
Will this recording suffice? https://docs.google.com/leaf?id=0B05KpXoNVpBeNTM2NDhlZTktY2FmMi00ODZlLWJmNDAtYWE1NWJiZDE5ZDdm&hl=en_US The link leads to a .TS file. This was made with vlc using the following command: vlc dvb://frequency=665028615 :dvb-adapter=0 :dvb-srate=0 :dvb-modulation=8VSB --sout=$dir/sample.ps
The following recording (in .TS format) may be better, as it does not play in totem. It does play in banshee. It was recorded via VLC's gui, so I don't know if the raw stream was just dumped or if it was transcoded. https://docs.google.com/leaf?id=0B05KpXoNVpBeYjhkMWI0MGYtNTRlNy00YmJhLTllMTMtODMwNDJkYTJjOTI2&hl=en_US
Is there any additional information needed for this? I'd be happy to help any way I can. I'd also like to help get qam working as well.
The two last files (from google docs) play fine with tsdemux for git. The first one (foo.mpeg) still causes issues though. Changing the title since it applies to main tsdemux.
Since these files all work and the first one looks like a badly captured file, I am closing this bug.
Thanks. In what version(s) should this be expected to work?
Mplayer seems to play the radio canada sample from comment #1 just fine, while both VLC and tsdemux choke on it.
In reply to comment #7, it's not that particular file being broken, every file created by mplayer -dumpstream will be like that, but not only that: apps like TotalMedia generate the same kind of files, see bug #754860 (unsure if they are 100% identical or not). A brand new file from mplayer exhibits the same behavior today: http://jeff.ecchi.ca/public/gstreamer-622809-mplayer-dumpstream-Tele-Quebec-2015-09-11.mpeg
mplayer -dumpstream is on crack. The CRC for the PAT is invalid. Don't expect *actual* players to deal with this (hint: try in vlc)
