avformat/rtsp : Send mode=record instead of mode=receive in Transport header
15 janvier 2024, par Paul Orlykavformat/rtsp : Send mode=record instead of mode=receive in Transport header
Fixes server compatibility issues with rtspclientsink GStreamer plugin.
>From specification :
RFC 7826 "Real-Time Streaming Protocol Version 2.0" (https://datatracker.ietf.org/doc/html/rfc7826), section 18.54 :
mode : The mode parameter indicates the methods to be supported for
this session. The currently defined valid value is "PLAY". If
not provided, the default is "PLAY". The "RECORD" value was
defined in RFC 2326 ; in this specification, it is unspecified
but reserved. RECORD and other values may be specified in the
future.
RFC 2326 "Real Time Streaming Protocol (RTSP)" (https://datatracker.ietf.org/doc/html/rfc2326), section 12.39 :
mode :
The mode parameter indicates the methods to be supported for
this session. Valid values are PLAY and RECORD. If not
provided, the default is PLAY.mode=receive was always like this, from the initial commit 'a8ad6ffa rtsp : Add listen mode'.
For comparison, Wowza was used to push RTSP stream to. Both GStreamer and FFmpeg had no issues.
Here is the capture of Wowza responding to SETUP request :

ffmpeg streaming video not in sync
3 avril 2019, par Tenaciousd93I have a problem saving a streaming with
ffmpeg.
The problem is that video is not in sync with audio.The video comes 2-3 seconds before the audio.
I try by removing and editing options but nothing change, I make some research too and I try all solution described in this great answer posted here, but it didn’t work for me.
I tried to download a chunk from playlist and I’ve got a
.tsfile with audio/video in sync.If I play the streaming with
VLC playerI can hear the audio without video for some seconds, then the video appear and is in sync with audio.ffplayplay the same streaming correctly too : seems like there is the time information inside audio and video codec and can be played correctly in sync.How can I ask ffmpeg to take audio and video in sync ?
If you need ffmpeg or ffplay outputs I will post them.
Edit : as requested, I report the full ffmpeg output of a simple command to save stream output to file :

Convert Webm to MP4 on the fly using ffmpeg for a Telegram bot using Typescript
23 novembre 2022, par HexI'm trying to make a very primitive telegram bot that get's a json and uploads the urls that are in the json to telegram.


The problem is that there are urls that point to webm files I tried to see if there is a simple way to do this and I found this : https://www.npmjs.com/package/webm-to-mp4
but it doesn't seem to work sadly, it runs into this error : "






throw new Error(`Conversion error: ${stderr}`)

input.webm: Invalid data found when processing input


I'm not sure what is causing it, my guess is that the webm-to.mp4 package was updated 2 years ago and something broke in the meantime.


Is there a better way to do this then downloading the webm converting it and then sending it up to telegram ? If not how could I do the conversion using just ffmpeg ?


Here is my current code :


import { Telegram, MediaSource, HTML } from 'puregram'
import { HearManager } from '@puregram/hear'
import { createReadStream } from 'fs'
import postsJson from './posts.json';
const { promises: fs } = require("fs");
const webmToMp4 = require("webm-to-mp4");

const telegram = new Telegram({
 token: '********:AAEzriis6zNNjEQuw0BxF9M2RPA9V4lEqLA'
})
const hearManager = new HearManager()

telegram.updates.startPolling()
 .then(() => console.log(`started polling @${telegram.bot.username}`))
 .catch(console.error)

telegram.updates.on('message', hearManager.middleware)

var posts = postsJson;

telegram.updates.on('message', (context) => {
 posts.forEach( async data => {
 console.error(data.ext);
 if(data.ext == "jpg" || data.ext == "png"){
 context.sendPhoto(MediaSource.url(data.image), { caption: data.content } );
 delay(1000);
 }
 if(data.ext == "gif"){
 context.sendAnimation(MediaSource.url(data.image), { caption: data.content } );
 delay(1000);
 }
 if(data.ext == "webm"){
 //context.sendDocument(MediaSource.url(data.image), { caption: data.content } );
 delay(1000);
 }
 delay(1000);
 })
})
fs.writeFile("file.mp4", Buffer.from(webmToMp4( fs.readFile("./file.webm"))));

function delay(ms: number) {
 return new Promise( resolve => setTimeout(resolve, ms) ); //This does not work either
}


I wish everoyne a nice day !
