let us first check the hadith, 2350 in abu dawud:
topic: when a man hears the call (adhaan/nidaa) and the vessel/plate is in his hand.
RasulAllah sallAllahu alayhi wa sallam said: "when one of you hears the call (nidaa) and the vessel/plate is in his had, let him not put it down until he has fulfilled his need from it".
------------------
the first mistake by the juhala is inserting: 'adhaan of fajr' in the hadith wording without any justification. indeed, we insert words in translation to clarify but it has to be justified. one cannot simply insert anything arbitrarily.
the speaker in the video repeatedly asserts that it is "the correct time of fajr," whereas such an indication is not found in the hadith nor can it be understood by the context, nor has any hadith master explained it thus.

let us consult the commentaries: imam abu sulayman al-khattabi (bio here), one of the earliest commentators of hadith works in his
ma'alim al-sunan writes:
i say: this is based (on the other hadith): "indeed bilal's adhaan (call for prayer) is in the night; eat and drink until (you hear) the adhaan of ibn umm maktoum."
or it means: if one hears the adhaan, but he is not sure that it was dawn break - for example, when the sky is cloudy and one would not know by just the adhaan that it was dawn, because the evidence for dawn is not present (due to darkness) - and if it was apparent to the mu'adhin (the caller) it would be apparent to the person as well (because they are both looking at the same sky).
and if he knows that the dawn has broken, then it is not necessary for him to wait for a loud aadhan (to intimate him that suhur time has ended) - because he is commanded to withhold from eating and drinking when the "white thread of dawn is distinct from the black thread". [khattabi]

jalaluddin suyuti, in mirqat al-su'uud sh. abu dawud, p.601:
in addition to citing khattabi (translated above) imam suyuti adds:
bayhaqi said: if the hadith is sahih, then it is to explained as the majority of scholars have opined that: RasulAllah sallAllahu alayhi wa sallam knew that the caller would call before the break of dawn, and thus if one continues drinking, it would be well before the break of dawn.
=============
we understand from the above that it was specific to the time of RasulAllah sallAllahu alayhi wa sallam and he knew about the prevalent practice.
in fat'h al-wadud sh. abu dawud of allamah muhammad sindi (al-kabir, d.1138 AH). 4/36
there is a slight variant of bayhaqi's statement which clearer than the previous:
bayhaqi said: if this is proven (or if this is a sahih hadith) - the majority (jumhur) explain it that RasulAllah sallAllahu alayhi wa sallam said so when the caller (munadi) would call before the break of dawn (tuluu al-fajr) such that one's drinking would be BEFORE the break of dawn.
i say: if you deliberate on this hadith and also the other: "eat and drink until bin umm maktoum's adhaan is called out" - because he would not call the adhaan until the break of dawn (tuluu al-fajr).
so also is the apparent meaning of the qur'ani verse - Allah ta'ala says: "until distinct for you is the white thread of the dawn from the black thread (of the night)". surah baqarah, v187.
this means that the basis (of ending suhur time) is the clear visibility of dawn - this is a short while after the start of the dawn - and the caller (mu'addhin) while waiting for the (correct time of) fajr may accidentally begin at the time of early dawn and it is permissible to drink (or eat) until the actual break of dawn. however, this is a well known difference of opinion among scholars and according to them, there is no reliance on this (hadith). Allah knows best.

in the video attached, the man has
badhl al-majhud of khalil ambhetvi, notorious deobandi-wahabi in the shelf behind him. alas! he could have referred to it at least before opening his ignorant mouth. khalil also explains the hadith as his predecessors:
