VLC 2.0.1 DVB-T Freeze + Memory Leak

[JGloria]

Hello, I'm having some trouble playing a DVB-T stream for a long period of time.

What's happening is that when I open my DVB-T stream, it plays fine for a while, until the picture + sound freezes, and the vlc.exe process starts consuming a huge amount of memory that goes up to 1.5 Gb. I can terminate the process and re-open the stream again, but I would like to know how can I fix this issue.

My TV tuner is a Asus MyCinema P-7131.

Thanks.

What does Tools -> Messages (set Verbosity to 2) complain when the freeze occurs?

After a few errors because of signal loss I get this.

This also happens with another TV tuner I have. The process also hangs most of the time and I'm forced to terminate it.

Hello, very similar problem here. Windows 7 64bit, VLC 2.0.1.
I'm watching DVB-T stream, if stream changes aspect ratio (e.g. 4:3 -> 16:9), picture freezes, but sound continues. Vlc.exe starts consuming memory. If i switch to another program, i can continue watching TV. If I don't after a while (2-3 minutes) vlc hangs. Debug messages (moment of ratio change, then I switch to another program).

Try VLC 2.0.2

[JGloria]

I thought 2.0.1 was the most recent version. Is 2.0.2 a nightly build? I remember trying with version 2.1.0 from the nightly builds and the process just crashes without being able to see the debug messages.

Can you please tell me where I can download version 2.0.2?

[Lotesdelere]

Can you please tell me where I can download version 2.0.2?

Nightly builds (vlc-2.0.0-xxxxxxxx-xxxx is v2.0.2).

[JGloria]

I tried that version and it crashes the process without giving any error messages, much like the 2.1.0 version I tried before.

Any other ideas?

[Jean-Baptiste Kempf]

Crash when doing what?

[JGloria]

It's streaming DVB-T normally and after a while it just crashes. It's random.

[Jean-Baptiste Kempf]

streaming or playin?

[JGloria]

Actually I want to correct my last post. It happened while playing though I think it happens in both playing and streaming.

[JGloria]

Any help?

[SonnenKoenig]

I found the following help for me while having issues with aspect ratio change (not in DVB-T streaming ...).

Changing in Video codec ffmpeg settings: ffmpeg-threads=1 (http://trac.videolan.org/vlc/ticket/6579) helped me. Does this also solve your issue? The real advice in this thread is a bit different but the thread option was helpful for me,

[JGloria]

Sorry to bump this old topic, but recently I've tried the latest version of VLC (2.0.4) to see if I'm still having the same issue. Even though the memory leaks don't occur anymore, I'm still having crashes during DVB-T streaming. When I open my stream with http remotely to play it, I get multiple "buffer way too early" errors and the stream crashes after a while with the message "ES_OUT_SET_(GROUP)PCR is called too late". I've tried different codecs and muxers and nothing has changed. I'm still kinda new to VLC so I could really use some help. This is the command I'm using to stream:


@START vlc.exe --intf=http -vvv dvb-t://frequency=642000000:bandwidth=8 :sout=#transcode{vcodec=h264,acodec=mpga}:duplicate{dst=std{access=http,mux=ts,dst=:63000}}

[Jean-Baptiste Kempf]

Does it crash also when playing?

[JGloria]

It doesn't crash but the video starts getting choppy with time and it freezes many times. I get the following messages while playing:

[Rémi Denis-Courmont]

Some of the content is encrypted. VLC cannot play it back.

[JGloria]

Are there any workarounds? I tried increasing the cache values after I saw some posts in other threads but it didn't solve the issue. This time after freezing while playing it eventually crashed and the VLC process closed.

[Rémi Denis-Courmont]

Obviously not.

[JGloria]

So there's no way to play the encrypted content unless I had some sort of encryption key that decoding devices use or some sort of algorithm to unscramble the signal?

There's not much I can do then?

[Rémi Denis-Courmont]

Right.
