php - FFMPEG conversion using shell_exec timeout for large files -


i'm trying convert large (40mb) mov file mp4 using ffmpeg , php.

but gives me 504 time-out error on server. can fix without changing set_time_limit ?

here php code.

shell_exec($this->getffmpegpath() . ' -i ' . $path . ' -vcodec libx264 -pix_fmt yuv420p -profile:v baseline -preset slower -crf 18 -vf "scale=trunc(in_w/2)*2:trunc(in_h/2)*2" ' . $convertedpath . '.mp4');

so, ideas on how convert without timeout ? appreciated.

you might want run converting in background. found this question addresses that, please more investigate on subject. can allow user refresh see whether process finished.

it might give better user experience (better looking @ page loading long time. there many places in connection may decide consider timeout: php engine, webserver, proxy, browser, depending on infra.

also should really careful shell_exec. chances of on web misusing whatever want machine quite high. maybe not in way using today (depending on $path , $convertedpath come from), maybe in future update of code allow user specify resulting filename example.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
