"Video stream not found" error

Hi, new user here with a trial installation of AntDM. My first download has twice failed to convert.

ENVIRONMENT

AntDM application 2.4.2 (unregistered) (so far!)
AntDM extension in Firefox 94.0.1 (32-bit)
Windows 10 Pro, version 21H1 build 19043.1320 (32-bit OS) (virtual machine)

Hardware:
Macintosh 2.50GHz Intel Core i5-2520M CPU
16GB system memory
Graphics daughterboard: AMD Radeon HD 6630M - 256MB


AntDM's video button reports the content as MP4 M3U8-AES128.



Downloading proceeds normally to 100% for about and hour and twenty minutes. At conversion time, the AntDM app logs an error and deletes the entire job:



It's about 3 hours seven minutes of video, served in 1,394 segments from twitcasting.tv. It won't do any good to post the URL without my login information, because it's paid content (but no DRM).

I tested a larger, publicly accessible video archive (2249 file segments) from the same host, and that download worked exactly as expected.

I'm using the AntDM internal conversion method (AntMPG.dll). I have not tried yet with FFMPEG.exe.

I don't know how to work with this problem. Can I prevent AntDM from deleting the captured video data when conversion fails?

I've made a copy of the <...v.init.ts> file. I can probably find a way to duplicate all 1,394 .mp4 files before AntDM kills them...

Thanks for any advice!

Following up: as you might expect, FFMPEG also logs exit code 1 when it tries to convert the downloaded files… and the whole download goes away.
