[FFmpeg-user] youtube formats not recognized by latest ffmpeg

[JD]

Dear all,
there are new formats on youtube that latest firefox cannot play,
neither can latest mplayer nor latest ffplay.
Example of these formats, as seen when one invokes
youtube-dl -F  <youtube-video-url> (such as
https://www.youtube.com/watch?v=pD5oUCVFmv0):

225          mp4        1280x534   720p 4534k , avc1.4d401f, 24fps, 
video only, 1.90GiB
226          mp4        1920x800   1080p 4614k , avc1.640028, 24fps, 
video only, 2.32GiB
227          mp4        1920x800   1080p 6378k , avc1.640028, 24fps, 
video only, 3.45GiB (best)

What player can play these formats?

Thanx.
