            How to send ffmpeg AVPacket through WebRTC (using libdatachannel)
            Asked 2022-Mar-31 at 10:48

            I'm encoding a video frame with the ffmpeg libraries, generating an AVPacket with compressed data.

            Thanks to some recent advice here on S/O, I am trying to send that frame over a network using the WebRTC library libdatachannel, specifically by adapting the example here:

            https://github.com/paullouisageneau/libdatachannel/tree/master/examples/streamer

            I am seeing problems inside h264rtppacketizer.cpp (part of the library, not the example) which are almost certainly to do with how I'm providing the sample data. (I don't think that this is anything to do with libdatachannel specifically, it will be an issue with what I'm sending)

            The example code reads each encoded frame from a file, and populates a sample by setting the content of the file to the contents of the file:

            sample = *reinterpret_cast *>(&fileContents);

            sample is just a std::vector;

            I have naively copied the contents of an AVPacket->data pointer into the sample vector:

            ...

            ANSWER

            Answered 2022-Mar-31 at 09:16

            The input files of the streamer example for libdatachannel use 32-bit length as NAL unit separator. Therefore, the H264RtpPacketizer instance is created with H264RtpPacketizer::Separator::Length.

            If I'm not mistaken the ffmpeg output will have 4-byte start sequences as NAL unit prefix instead (which is actually more common), so if you change the packetizer setting to H264RtpPacketizer::Separator::LongStartSequence it should accept your sample.

            Firstly I would highly recommend you use react native with functional components and React Hooks as they alternative will soon will be deprecated.

            Since onPress is not available on the View Component, you would need to replace it with TouchableWithoutFeedback as you have already done in your code.

            For Showing/Hiding a view you would need to use a conditional operator.

            You are modifying a data streamer after it was created, which is not supported. After the instance is created, you can obtain only a copy of its configuration. Provide the complete configuration on initialization instead:

            I would personnally not use PHP to stream the video. The problem is that you'll have to many PHP processes locked for reading and streaming a big file instead of handling logic. You will also have a PHP timeout during this process.

            Instead, I would use the Sendfile module:

            • You install an Apache module or other kind of Sendfile module for your web server, NGINX or whatever.

            • In PHP, you do the logic for the protection and just send a HTTP header to say you want Sendfile to handle the streaming. This way your PHP code stops running and its the web server that handles the transmission of the file.

            I've forked and modified your project on GitHub. Working code and setup instructions can be found here.

            Here is how it looks with 4 tabs open. You can see local session id on top right and corresponding sessions ids on each remote videos. I used VCam for debugging. That's why the trial text:

            There are some issues to fix:

            1. Major issue is the comparison if (y != "complete"). You are comparing event object with "complete" string. You end up sending offer SDP without any ICE candidate. Using if (self.peerConn.iceGatheringState === "complete")ref fixes part of the problem. With this change Receiver sees the Sender's video.
            2. From Receiver side you create answer and send back SDP immediately. ICE candidate collections starts after you call createAnswer() or createOffer(). So you are sending SDP without any ICE candidates.
              After you fix this other issue is that on Sender side there are no onAddStream and streamEventsChangedHandler handlers. Thus Sender never gets to set received stream to corresponding element.
            3. RTCPeerConnection is capable of both sending and receiving video/audio streams with same connection object. You can set setRemoteDescription() on Sender as well. You don't have to maintain separate Sender and Receiver connection objects. Major improvement here could be you combine Sender and Receiver classes in to one Connection class. This way you create only n-1 connections, for n participants, at each participant side. And on server you need to track only n connections and not n*(n-1).
            4. RTCPeerConnection.onaddstream is deprecated. Use RTCPeerConnection.ontrack property
            5. Serve web pages over secure channel(HTTPS). Because browsers won't let your web page access media hardware over insecure(HTTP).ref. Localhost(127.0.0.1) is exception.
              You can configure tomcat7-maven-plugin in pom.xml to serve pages on HTTPs. Steps to setup HTTPs are in the README.md file.
            6. You need to have more timeout delay. 2 seconds is very less. Clients may have very low latency streaming among them, due this direct P2P connection, and high latency connecting to your server. So if they can't connect to server doesn't mean they stopped communicating. Once you establish connection between clients the server's role is over until they logoff explicitly.
            7. Due to Chrome autoplay policy you can't start playing other's video directly. So had to add an overly over the page to force user interaction. This won't be an issue once you have login implemented.
            8. Acquire local media streams before you create Room object, preferably immediately after page load and before user get past overlay. If user delays providing device access permissions, your Room object will have already completed all connection procedures with other peers without sharing any local audio/video streams. If you handle it later you'll have to add tracks/streams to all connections again.
            9. Did little bit of restructuring. On server side I moved public inner classes from MeetSessions.java to separate files. It was getting hard to understand the code. Something with the index.html.

              I've tested the code in LAN/Wi-Fi using Windows PC, Android phone, and tablet. If you host your server in public domain you may need TURN server as well for these reasons.

            if this is for scraping the data, then price_disney = html_disney.find( "span", class_="fin-streamer Fw(b) Fz(36px) Mb(-4px) D(ib)") is incorrect.

            To get the tag fin-streamer and class Fw(b) Fz(36px) Mb(-4px) D(ib) your code would be price_disney=html_disney.find("fin-streamer", {"class": "Fw(b) Fz(36px) Mb(-4px) D(ib)"}).text and then you can type cast it to float. So code will be like

            price_disney=html_disney.find("fin-streamer", {"class": "Fw(b) Fz(36px) Mb(-4px) D(ib)"}).text
