html5 - uploaded video only audio is displayed -

i trying upload mp4 file. specefic file sound content displayed.

with other videos there no problem specefic one.

i found next question:

html5 video of type video/mp4 playing sound only

where suggest find converter.

does know if problem , how secure regardless of video user uploads able play?

yes, can problem.

you have not written server limitations, if have possibility execute converters (like ffmpeg) best solution. way can guarantee fixed resolution, framerate , various other properties, , server won't eat space if uploads 2gb video... (users can dumb sometimes.)

if cannot run ffmpeg on server seek reading how can observe codecs on server, in language use, etc. then, if still want to, post specific question.

also seek opening videoplayer page different browsers (chrome, ff, ie @ least). might not back upwards codecs same way.
