It's disappointing the person who uploaded this clip has done so in a clearly obfuscatory way.
Some background:
I (BJJ black belt under De la Riva) noticed a technique that looked remarkably like a de la riva sweep while watching a longer video about judo. I made a gif of it and posted it to Reddit r/bjj
https://www.reddit.com/r/bjj/comments/2on6f6/tsunetane_oda_de_la_riva_sweep_early_1900s_judo
I posited that it resembled a DLR sweep, and asked for people's thoughts on the matter.
The evidence is uncertain as the camera angle makes it difficult to clearly see the position of his hooks, and it was the lone technique from that position on a much longer video. Myself and many others recognise the similarity, but the motion of the sweep and way Oda elevated uke looked somewhat different to a 'traditional' DLR sweep from that position.

The 5-second gif was uploaded to YouTube by "R H Marcus". The uploader almost exactly copied my thread title from Reddit, but with a notable difference
Reddit thread title: "
Tsunetane Oda, de la riva sweep? Early 1900s judo video"
YouTube video title: "
Tsunetane Oda - 'De La Riva Sweep', Early 1900s, Kosen Judo"
The uploader removed the question mark so as to remove doubt over the exact nature of the technique. Instead of questioning the technique in clip, he's making a statement that this IS as per the title, which IMO is deliberately misleading.
I tried discussing this with him in the comments to the YouTube video, along with others who also took issue with his appropriation of the technique and misrepresentation of the origin of the DLR guard.
He deleted the comments.
This leads me to believe that he is one of those "BJJ is 'basically just judo'" types that will distort facts to belittle recognition of jiu-jitsu techniques and positions. I always found it weird there is a vocal minority who seek to put forth that modern developments of jiu-jitsu already existed in judo
