td Supported video formats

It would be nice to document what is supported. .webm with VP8 apparently doesn't play.

The only video format that is guaranteed to work is .MPEG4 with H.264 video codec and AAC audio codec. Some other video formats or codecs may work but this isn't guaranteed. This is documented for bots at https://core.telegram.org/bots/api#sendvideo. Regular apps are supposed to reencode videos using system-provided tools to .MPEG4, or can't affect video format, hence this doesn't usually matter for them.

@levlam it would be nice to support at least one open source codec in addition to proprietary H.264, because some platforms disallow binary blobs that can not be audited.

P.S. Thanks for the reply.

You shud M use P4 (H.264/AAC): Browser Support: Universally supported across all major browsers (Chrome, Firefox, Safari, Edge, etc.).

@manishwalia15 browsers may support, but company or regulator policy may not, especially those who take security seriously.
