No, use filesize metafield from format dictionary of JSON output.

Here is what I get with jq

null

Can you be more precise ?

YouTube does not provide all filesize information for all formats. In this example only DASH formats have the size information.

$ youtube-dl -f 133 -j http://www.youtube.com/watch?v=29S1T7RNHGM | jq .filesize 
140629453

Hi,

If "YouTube does not provide all filesize information for all formats", why not use the "Content-Length" found in the HTTP headers to implement the --get-size option, example:

curl -sI "$(youtube-dl -g -f 18 http://www.youtube.com/watch?v=29S1T7RNHGM)" | awk '/Content-Length:/{printf "%.2f MiB\n", $2/2^20}'

Content-Length is not available before you really starts the download. Data reported by -j are extracted from web pages and API responses.

Why not use a curl subprocess or libcurl to extract Content-Length ?

A reason is that querying the filesize for all formats takes a long time. This can be a feature request if the additional time cost is tolerable. If you're interested in only one format - just do the curl call.

"querying the filesize for all formats" does not make any sense according to me.
I am only interested in only one format.

Why not include the curl or libcurl call in youtube-dl instead ?

It's possible with pure Python. This ticket is actually a duplicate of #190 and #6. Sorry for not noticing previous ones at first.
