Hello community

I try to download and convert a video in mp4 format, with the VideoDownload Helper plugin in my firefox browser. Unfortunatelly the convert is crashing.

The log shows following informations. How can this issue be solved?

Hi Jerome.

Here the Link

First, I changed the resolution of the clip from the default to 1920x1080 using the
techniques I describe here:

https://groups.google.com/g/video-downloadhelper-q-and-a/c/zW_fNhqqYVs

Then I downloaded that MKV. I did not do a Download & Convert because I wanted to make
sure I could get the clip first. I did & it played just fine in VLC, video & audio all
the way from beginning to end, which I verified by skipping through the clip & sampling
it at random points, including the last few seconds.

Then I used the VDH convert local file function to turn it into an MP4. That worked as
well. The input MKV was nearly 600M & the output MP4 was just over 700M. The conversion
took about an hour using nearly 100% of my quad CPU. Conversion is CPU intensive . . .
he said, in a massive understatement. Nevertheless, the rest of my system continued to
be responsive throughout that time. Once the conversion finally completed, the resulting
MP4 played fine, with both video & audio, as well.

I'm running Windows 7 64-bit, Firefox 88.0.1 64-bit, licensed VDH 7.4.0a1 beta
(equivalent to the general availability release), CoApp 1.6.2.

Have you tried this more than once?

[Ramon Lustrati]

Hi Willy

I tried it but in my environment it didn't work. 

I started a Download and opened the file with VLC viedo. Unfortunatelly only the audio was captured. No Video.

Running Download & Convert, the program crashed ...

Can you try in your environment if it works?

That's because you didn't read the other thread. Click the link I posted a few days ago
& go read the other thread. The instructions are there in the images I posted. Read
them. Follow the instructions. It will work.
