swresample/resample : optimize exact_rational=on:linear_interp=on case
24 novembre 2016, par Muhammad Faizswresample/resample : optimize exact_rational=on:linear_interp=on case
separate dsp.resample to dsp.resample_common and dsp.resample_linear
and choose to call faster resample_common even when linear_interp=on
when c->frac and c->dst_incr_mod are both zerospeed up resampling when exact_rational and linear_interp are both
enabled because exact_rational force c->frac and c->dst_incr_mod to
be zero when soft compensation does not happenbenchmark on exact_rational=on:linear_interp=on

Why does File upload for moving image and Audio to tmp PHP folder work on Windows but only image upload portion works on Mac using MAMP ?
31 mai 2021, par YazdanSo according to my colleague who tested this on Windows says it works perfectly fine , but in my case when I use it on a Mac with MAMP for Moodle , the image files get uploaded to the correct destination folder without an issue whereas the audio files don't move from the tmp folder to the actual destination folder and to check if this was the case ... I just changed and gave a fixed path instead of
$fileTmpLocand the file made it to the correct destination. Sorry I know the first half of the code isn't the main issue but I still wanted to post the whole code so one could understand it easily, moreover I am just beginning to code so please "have a bit of patience with me" . Thanks in advance

I am a student learning frontend but a project of mine requires a fair bit of backend. So forgive me if my question sounds silly.


What I meant by manually overriding it was creating another folder and a index.php file with
echo "hello"; $output = shell_exec("ffmpeg -i Elephant.mp3 -ab 160k -ac 2 -ar 44100 -vn bub.mp3"); echo $output;so only yes in this caseElephant.mp3was changed as the initial tmp path so in this case as suggested by Mr.CBroe the permissons shouldn't be an issue.

Okay I checked my
Apache_error.logonly to find out ffmpeg is indeed the culprit ... I had installedffmpegglobally so I am not sure if it is an access problem but here is a snippet of the log

I checked my php logs and found out that
FFmpegis the culprit.
Attached is a short log file
