In the first example, where is the text file referenced?

In the second example, are links defined by the -a and -r arguments?

Are there always exactly two quoted strings in the relevant line of the text file?
Do these lines always contain a unique keyword, like e. g. "meta"?
And, most important: Is there just one line in the textfile containing that keyword?

If so you can try this:

links=$(sed  -n '/meta/s/^.*"\(.*\)".*"\(.*\)".*$/\1 \2/p' textfile)
link1=${links% *}
link2=${links#* }
echo $link1
echo $link2

Alternatively, use awk. This will work even if there is just one quoted string, but we'll need a check to avoid link1 and link2 being the same in that case:

links=$(awk -F\" '/meta/ {if($4=="") $4="dummy"; print $2, $4}' textfile)
link1=${links% *}
link2=${links#* }
[[ $link2 = "dummy" ]] && unset link2
echo $link1
echo $link2

If there are (can be) several lines in the textfile containing the keyword and the links we must create a loop and work with arrays instead of single variables.

did not work

Are there always exactly two quoted strings in the relevant line of the text file?  yes

And, most important: Is there just one line in the textfile containing that keyword? no

links always changes just some word that does not change
link1 rtmpe: // does not change
link2 mp4 does not change

<smil><head><meta base="rtmpe://yoyo.com/vod"/></head><body><video src="JPMAK9ytVw3fzAxHuweyyeuw3743434kn3j4huyd67cuj3nr$$%fjudfyDWIe9XM2BElbQ74JZnAHm5RYe3EUm5J9AmZdpeJdK78VaGdw%3D-p%2BdQbrgVg7oqPMKmM16KQw%3D%3D.mp4?audioindex=0" /></body></smil>

Given the data you posted both of my scripts will show

for link1:
rtmpe://yoyo.com/vod

for link2:
PMAK9ytVw3fzAxHuweyyeuw3743434kn3j4huyd67cuj3nr$$%fjudfyDWIe9XM2BElbQ74JZnAHm5RYe3EUm5J9AmZdpeJdK78VaGdw%3D-p%2BdQbrgVg7oqPMKmM16KQw%3D%3D.mp4?audioindex=0

which exactly represents the two quoted strings which you asked to extract.

So why do you say "did not work" (apart from the fact that such a phrase is rude, at least extremely impolite)?
