I used this with youtube-dl: youtube-dl -f 135+18 … and result was mp4 with 135 video and audio from format 18 (360p vid, 96kbit audio) so I get 480p vid with smaller file size than by using -f 135+140. I used yt-dlp as drop in replacement and now I realized that it downloads only f135 so no audio on result files… Is it possible to achieve this with YT-DLP? I tried some combinations and no luck so far.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

Oh, I just noticed that using --video-multistreams instead of --compat-options multistreams achieves the same thing here. Not that it really matters, it’s just shorter and more precise.
