When streaming data from a web camera using PHP's print function, some buffering seems to occur. At low frame rates, the feed freezes and then displays multiple frames rapidly. This issue is suspected to result from the output buffer.
Step 1: Disable output buffering
Globally, by disabling output_buffering in php.ini or Apache config:
php_flag "output_buffering" Off
Step 2: Disable server-level output buffering
PHP employs two layers of buffering: the output buffer and the write buffer/server buffer.
Output Buffer
Write Buffer and Server Buffer
