goldvideo / demuxer Goto Github PK

Hi, i was curious how i would approach the remux into mp4?

Currently i am reading the data via WebSocket and is being sent over mpegts and I want to add this into a HTMLMediaElement via the SourceBuffer API but i need to demux and then remux in to mp4 to allow for this, as far as i know.

您好，我在用 demuxer的TSDemux来解封装时，该mpeg-ts是个双音频文件，导致播放时会出现双声音并导致播放问题(而且解析出来的数据stream_id都是一样的），有什么方式来识别音频1音频2，并只保留单条音频吗？

👋 Hey @gemxx, @jarry, @nemo-shen! I'm working on an open source, all-in-browser video editor utilizing the new WebCodecs APIs and am looking for a Typescript mp4 transmuxer alternative to mp4box.js.

Just wondering if you guys are still planning to maintain this project in any capacity? If not, would love any advice for going down the path of doing something similar.

Thanks for your work and hope you all are doing well!

In the PesStream class, there is a filter on the PID, only allowing output for values of greater than 255. It's line 40 of pes.ts:

if (packet.PID > 0x00ff && packet.PID < 0x1fff) {

Why is this lower limit there? According to the spec, the lower limit should be greater than 31, or 0x001f.

I have a hardware encoder that is outputting a PID of 68 on its video stream, and I can only demux it if I change this limit. Can this be changed?

Hello @gemxx can you please add a node.js example?

Currently it seems that the package on npm does not include types.
Can we please include the d.ts files in the package to support type checking.

This can be accomplished by setting the declaration: true flag in tsconfig.

假设我知道ts文件一定是h265的,那么我怎么知道解码出来的PES包里的数据是关键帧
