Does not generate a video container when selecting a custom audio ID
Does not generate the audio muxing in the video container if a custom audio ID is selected, only the audio is downloaded, not the video stream either. It is not possible to get the debug log in plain text.
I want to download video with m4a (AAC) audio for compatibility reasons. Generally it is the audio ID 140 obtained with the -F parameter of yt-dlp. It happens with any youtube URL.

}
int main() {
std::string videoId = "<VIDEO_ID>"; // Replace with actual video ID or URL
std::string outputFileName = "output.mp4";
downloadVideoAndAudio(videoId, outputFileName);
return 0;
}
The problem persists on my machine. Version 2025.5.1. This happens when Video (generic) is selected.
