My installation.
Win7 pro 64bit, VLC player v2.2.4 (Weathermax) 64bit running on Intel I7 /950

VLC player has operated without any problems with all video file formats that I had fed it, so in general nothing flawed with the installation.
VLC player will not play a video file(s) that has been recorded on an Aldi/Bauhn TV using the PVR funtion.
It is nominally given a .TSV file extension, but other program report it to be in an MPEG-TS container.

The video plays correctly with other video player programs: 1. ffplay 2. GOM 3. Win mediaplayer.
VLC media player either produces no audio and no video (just a flash of a second or so to the larger video window) for a short video file (10- 40 MB)
and a garbled (mainly gray) screen with advancing timeline on a large( 2Gb / 1hr) video file.


The log files (below) from ffprobe, ffplay, GOm player indicate that the video uses an mpeg2 codec -- fairly standard and which I though should be readily handled by VLC.
ffplay uses the mpeg2video library codec to correctly decode the file. Is my understanding correct that the same (similar?) mpeg2video library is used in VLC?
If this is the case, then it may indicate that there is some sort of problem in VLC player.

Have also tried the latest nightly build and there is no change in behaviour.

Any clues / suggestions?

regards,
Joe

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com if it's too long.

Also upload a short sample of a problematic file to either http://streams.videolan.org/upload/ or to Zippyshare.com (200 MB max) or to EmbedUpload.com, the latter will upload the file for you to several other hosts (use the default ones) and then post the link to the file here.

If needed cut it with DGsplit and read here about how to do it:
viewtopic.php?f=14&t=57724&p=193335#p193335
50 MB max should be enough.

I had tried to upload a video file initially, but was not successful, but now have succeeded - (http://streams.videolan.org/upload does not seem to be responding).
Lotesdelere, thanks to your guidance.

I have followed your instructions and a video file (Bauhn_1.ts) which fails to play has been uploaded to Zippyshare.com This file is approx 42Mb
http://www88.zippyshare.com/v/D7vrGc61/file.html

The logfile has also been uploaded to Zippyshare.com
http://www88.zippyshare.com/v/IimamF8d/file.html


Subsequent observation.
The VLC log file appears to be reporting errors in the encoding of the video file and having difficulty in deciding upon the correct codec.
As an experiment, I processed the video file through ffmpeg ---- just using a copy function

ie ffmpeg -i bauhn_1.ts -c: copy all.ts

and the file produces plays properly with VLC player.
This would tend to indicate to me that the original PVR produced file may not be not well formatted / compliant with the standards, but unfortunately VLC player is not as robust or tenacious in dealing with a video file that has encoding/format issues as well as say ffmpeg / ffplay or some of the other players.
VLC player is my strong pref above the others, so would love it to work.


regards,
Joe.
