Streaming via Allcast to Chromecast

Hello,
I am not sure if this is the right place to post this question. I am pretty tech savvy but this has been stumping me for days now. I am using Kodi on my Samsung Tab A 10.1 using Allcast to stream to my Chromecast. Alot of the videos play via chromecast fine with zero issues in quality and sound. However there are some videos that dont and give a weird error with the little shit emoji saying something about “No Codec found” “visit handlebar.fr” I have the 1st generation Chromecast….does Chromecast not support all video formats? Kinda weird that Google would drop the ball on that…if thats the case is there some sort of work around for this so I can watch everything Kodi via Chromecast? Or do I need to get a roku or firestick to play everything? Anyone know? I have been searching google for hours and cannot find a straight answer.
