[Solved] avidemux3_qt5 segfault

[nobanzai]

Hi *,

I am trying to convert a bunch of .ts files recorded by my DVB-S2 receiver to an mpeg file and get a segfault.
The input files have h264 format for the video stream, two mp2 and one ac3 audio streams.
I configured Mpeg2 (ff) as Video Ouput,  MP2 (lav) as Audio Ouput and MPEG TS Muxer (ff) as Output Format.

I get:

Am I doing something wrong here or is it a bug in avidemux?

Thx and bye.

A Ts that causes the problem would help

[nobanzai]

Hi,

ok, any special place to upload it?
Or just dropbox?

Bye.
Michael.

[mean]

dropbox, mega ..

[nobanzai]

dropbox, mega ..

what address should have access to the shared Dropbox folder?

[Jan Gruuthuse]

None, create a link [share] next to file. Provide that link. like in this posting : http://avidemux.org/smif/index.php/topic,17019.msg76799.html#msg76799.

[nobanzai]

Hi,

thx for this hint.
I tried that yesterday, but on a first look it seemed to be impossible with the free version of a Dropbox account.

Tried it again today and it worked:
The link is https://www.dropbox.com/s/c7lkklzf6a8u28i/00001.ts?dl=0

Bye.
Michael.

[Jan Gruuthuse]

That is a bloody 2 GB download!
Record 1 minute and upload that.
What is your recording hardware and recording source DVB-T / DVB-T2 / DVB-C / DVB-C2 / DVB-S / DVB-S2

ok, I can do that - but this is the recording that caused the crash.

I use a bunch of Terratec cards for recording:

2 x TT Budget S2-3200
2 x TT Premium S2-6400

The problematic recording is from a DVB-S2 channel.

It is not clear to me if this is related: probably dev(s) have a better insight:

yes, I know - was that just a hint or is there any connection to my problem?

try re-muxing the video with mkvtoolnix gui https://mkvtoolnix.download

Did it - no errors or warnings occured.

[Jan Gruuthuse]

think this one is for developer(s) to look at.

Hi,

thx for analyzing this problem.
Do I have to write a bug report? Or do you talk to some developer?

Bye.
Michael.

The mpeg2 encoder default settings are for DVD
You are using FullHD, so either :
* Resize it to DVD style (i.e. 720*576 or similar)
* Increase the buffer size / max bitrate of the mpeg2 encoder, multiply everything by 3 or 4

I've started the encoding, so far so good
(The mpeg2 encoder was broken in 2.6.13, you *must* use a nightly)
