video

问题 I am trying to stream Telegram video files and play them on a web page. I am using this script to stream Telegram videos to a web server. It uses Telethon and AIOhttp to stream the file. The streaming part can be seen here. I am currently serving it on a server to serve media files. The videos can be downloaded using the link the script provides and can be streamed on any media player. But when I try to stream them on a web page, it has problems. For mp4 videos, Chrome does not play them

问题 We are working on a project to convert video to audio, and this is the sample code: from converter import Converter from moviepy.editor import * c = Converter() clipv = 'g.mp4' clipc = VideoFileClip(clipv).subclip(0,20) conv = c.convert(clipc, 'clip5.mp3', {'format':'mp3','audio':{'codec': 'mp3','bitrate':'22050','channels':1}}) for timecode in conv: pass However, it gives me this error Traceback (most recent call last) File "del.py", line 7, in <module> for timecode in conv: File "/usr/local

问题 I'm tasked with revising an application which uses DirectShow for video rendering. The old application works fine, but it's starting to show age. As I have a gaming background, I figured I should just approach this as such. After having made a bunch of prototypes using different techniques, I was pretty sure I could pull of video-to-texture rendering and use DirectX to fulfill all the clients his requests. However, I'm now at the point I have to pick a technique to go with and I couldn't be

问题 As an example, say I have a video object set on my website with the following attributes: <video controls="" preload="auto" id="_video"></video> and the original source being ./video/video.mp4 (for example). How can I go about protecting the original source files location through converting it to a BLOB url ? I have seen a few posts stating that it needs to be done within through JavaScript, but none of them actually go to the extent of explaining how to do it, or where you can find out. So,
