Error video not found

При просмотре видео в сети мы можем внезапно столкнуться с ошибкой воспроизведения, сопровождающейся сообщением «html5 Video file not found». Ошибка встречается на различных видеохостах типа Vimeo, YouTube и других, и обычно связана с некорректной настройкой сайта его веб-мастером или отсутствием поддержки технологии HTML5 у пользовательского браузера. Ниже разберём, в чём суть данной проблемы, и как избавиться от неё на вашем ПК.

Модерный HTML5

Как известно, технология «HTML5» является усовершенствованной версией технологии «HTML» (язык гипертекстовой разметки). Как следующий уровень развития HTML, HTML5 включает видео и аудио спецификации, позволяющие пользователям смотреть видео онлайн без каких-либо плагинов.

Для работы указанной технологии веб-мастерам нужно задействовать специальную кодировку HTML5, и использовать форматы WebM, MP4 и OGG на страницах своих ресурсов.

Вы можете просматривать видео HTML5 на всех популярных браузерах, включая Гугл Хром, Мозилла, IE, Сафари и других.

Ошибка «html5 Video file not found» — причины появления

Рассматриваемая ошибка обычно возникает при попытке просмотра видео, размещённого на какой-либо веб-странице. Часто она связана с некорректной настройкой сайта, и может быть исправлена лишь веб-мастером данного ресурса.

В некоторых случаях проблема может быть вызвана некорректной работой браузера, не поддерживающего кодеки HTML5. Вы можете проверить эту гипотезу попытавшись запустить проблемное видео на другом браузере.

Также фактором проблемы могут выступать кэш и куки браузера, не позволяющие корректно воспроизводить видео с данной веб-страницы.

Перегрузите веб-страницу

Наиболее простым способом решить проблему является обновление проблемной веб-страницы. Нажмите на F5 (Ctrl+F5) в браузере, и после обновления страницы попытайтесь воспроизвести необходимый вам видеоролик.

Очистите кэш и куки веб-навигатора

Также рекомендуем очистить кэш и куки вашего браузера. К примеру, в Мозилле это делается переходом в настройки, выбором слева раздела «Приватность и защита», и нажатием на кнопку «Удалить историю» чуть ниже.

Отключите аппаратное ускорение

Как известно, аппаратное ускорение помогает при работе с графически-насыщенными медиа типа игр, видео и др. в вашем браузере. Когда вы отключаете аппаратное ускорение в браузере, только графический процессор вашего ПК может быть использован для работы с графическими медиа. Это снижает нагрузку на браузер, и может устранить html5 Video file not found на вашем ПК.

Аппаратное ускорение может быть отключено в настройках вашего браузера. К примеру, в Гугл Хром это делается переходом в настройки навигатора, выбором опции «Дополнительные» в самом низу, и отключением опции «Использовать аппаратное ускорение» с помощью соответствующего ползунка.

После отключения данной опции перезапустите браузер, и попытайтесь воспроизвести нужное видео.

Запустите навигатор в безопасном режиме

Старт браузера в безопасном режиме может помочь избавиться от рассматриваемого нами сообщения. В данном режиме отключается работа расширений и дополнений браузера, деактивируется аппаратное ускорение, сбрасываются ряд настроек.

Если видео запустится в безопасном режиме, значит какая-либо из указанных настроек вызывает рассматриваемую нами ошибку. Вы можете изменить такие настройки, отключить плагины и устранить релевантные причины, вызывающие ошибку HTML5.

К примеру, для запуска Мозилла в безопасном режиме необходимо нажать на кнопку с тремя горизонтальными линиями справа сверху (Открыть меню) в браузере. Далее выбираем «Справка» — «Перезапустить без дополнений».

Обновите ваш веб-браузер

Поскольку не все браузеры поддерживают работу с HTML5, вам необходимо убедиться, что вы пользуетесь самой свежей версией вашего навигатора. Технологию HTML5 поддерживает браузер Хром с 26 версии, Мозилла с 21 версии, Сафари с версии 6.1, Опера с 15 версии и далее. Проверьте, установлена ли у вас самая свежая версия веб-навигатора, и при необходимости установите таковую на ваш ПК.

Обратитесь к веб-мастеру сайта

Во многих случаях рассматриваемая проблема может возникать из-за того, что проблемная страница не имеет должный кодек для воспроизводства видеоролика. В этом случае можно попробовать связаться с разработчиком сайта, дабы тот установил HTML5 кодеки для форматов WebM, MP4 и OGG.

Заключение

В нашей статье мы разобрали, что за проблема html5 Video file not found, и как её устранить. Если стандартная перезагрузка страницы ничего не даёт, попробуйте очистить кэш и куки браузера, отключить аппаратное ускорение или запустить браузер в безопасном режиме. Если же это не помогло, попробуйте установить самую свежую версию браузера, или использовать альтернативный веб-навигатор от другого разработчика. Также будет не лишним обратиться к веб-мастеру проблемного ресурса – возможно дисфункция с работой видео HTML5 вызвана некорректной настройкой функционала самого сайта.

Clear Out Browser Cache Files, Cookies, and Data 

Google Chrome uses the browser history to streamline easy access. The cache files & cookies help load websites faster for a better user experience. But sometimes, these data can lag and cause video playback errors. To resolve this issue, head on to your browser settings and clear out your data.
