Hey,
I noticed an interesting issue. For some reason, there is no DASH video listed in the "-F" output, although there are several DASH audio listed there.

However, I think format 136 should be DASH video. is that correct ?

DASH is nominal here since Youtube does not serve manifests any longer.

Thanks Dstftw,

Do you happen to know when youtube stops serving manifests ?
