Video

Pyloid is based on Qt WebEngine, which only supports open-source codecs. This is a policy to avoid patent issues, so proprietary codecs like MP4/H.264 are not supported.

When you need to play videos in your web application, you must use videos encoded with open-source codecs.

Supported Video Codecs

The open-source video codecs supported by Pyloid (Qt WebEngine) are:

VP8 - Used in WebM containers
VP9 - Used in WebM containers (improved compression over VP8)
WebM - Container format using VP8 or VP9 codecs

Unsupported Video Codecs

The following codecs are not supported due to patent issues:

MP4/H.264 - The most widely used codec but protected by patents
H.265/HEVC - Successor to H.264
Other proprietary codecs

Basic Usage

You can play WebM format videos using the HTML5 <video> tag:

<video
    src="https://dl11.webmfiles.org/big-buck-bunny_trailer-.webm"
    controls
    width="640"
    height="360">
</video>

Using Local Video Files

When playing locally stored WebM files:

<video controls width="640" height="360">
    <source src="/videos/my-video.webm" type="video/webm">
</video>

Important Notes

MP4/H.264 files will not play in Pyloid applications.
Videos must be converted to WebM format before use.
Large video files can increase your application's distribution size, so appropriate compression is necessary.
If loading videos from external URLs, check CORS policies.
