Hi

The merge of video and audio is managed by youtube-dlp.

Could you download the given example in command line with yt-dlp.exe (the one in the install folder), and check if they are merged?

Regards,

I checked via the command line. I uploaded the file that is included in the program. Video and Audio are combined into one file. You can check it yourself. This is the content. https://revoir.tv5monde.com/toutes-les-videos/art-de-vivre/maisons-hotels-de-legende-beau-rivage-palace

Hello,

I tried the example, the audio and video are downloaded separately but they are merged at the end.

I think that TV5Monde maybe doesn't give all the metadata. If so, ArrowDL gives the feeling that the file is actually downloaded while some steps aren't finished. The progress bar is based on assumed size of the file, but if TV5Monde says the file is 0 kB (ex: the audio), then the progress achieves 100% while one of the file (audio in this case) is still downloading.

=> For streaming servers that don't give all metadata, we should not trust the progress status. Instead, just wait enough time until the progress bar is dark green and/or the ETA -estimated time- is at "download finished").

If still cumbersome, maybe open a ticket on the yt-dlp github project, maybe they could take the TV5Monde issue into account?

Regards

But DownZemAll 3.1.0 using the same yt-dlp combines Video and Audio files into one file very well. I use portable ArrowDL 4.0.0. Could there be a problem with portable version? In the portable ArrowDL 4.0.0 the matter is something else. I tried to download the file again and waited until it turned dark green, but it still downloaded two files and they were not combined. I will use portable DownZemAll 3.1.0 , It suits me quite well.
