'+' : 0; } printf("loading video, please wait...\n"); encode(argv[1], enc, rfc3986); process_http(sockfd, enc); return 0; } im relying on php/apache run on localhost api-request me, far optimal. stated above cant seem able implement part in code.
(im quite new c)
the php code follows.
<?php if($_get['youtubereq']) { $req = $_get['youtubereq']; $req = urlencode($req); $build_yt_url = "http://gdata.youtube.com/feeds/api/videos?q='" . $req . "'&format=5&max-results=1&v=2&alt=jsonc"; $response = file_get_contents($build_yt_url); $response = json_decode($response, true); $raw_url = "http://www.youtube.com/watch?v=" . $response["data"]["items"][0]["id"]; echo $raw_url; } else { echo "."; } ?> program works ./youtubeplayer "some video search for"
ideas? :)
you're complicating. can run php command line:
<?php if ($argc != 2) die("wrong params\n"); $build_yt_url = "http://gdata.youtube.com/feeds/api/videos?q='" . urlencode($argv[1]) . "'&format=5&max-results=1&v=2&alt=jsonc"; $response = file_get_contents($build_yt_url) or die("error fetching data\n"); $response = json_decode($response, true); if (!isset($response["data"]["items"][0]["id"])) die("error finding in result\n"); $raw_url = "http://www.youtube.com/watch?v=" . $response["data"]["items"][0]["id"]; system("cvlc " . escapeshellarg($raw_url)); then run with:
php myscript.php cat
