QUESTION
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 09:16The 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.

I am scraping the stock prices, and names from Yahoo's finance website. After making a dataframe with three columns "Name", "Code", and "Price" and representing the passed index variable. I want to go to another loop and add a column to the original dataframe with updated prices. But when I add the column it creates NaN values for my original data. What do I need to do to correctly place the indexes and not disturb the original dataframe data?

QUESTION
I'm learning React Native for the first time. I want to implement a function to show/hide the component by touching the screen, not a specific button.
(Please check the attached file for the example image.)
In this code, I've tried to make a function. if I touch the screen (, then show/hide the
renderChatGroup()
and renderListMessages()
included in . The source code is below.
In my code, it works. However, the two tag is not parallel. the footer view is center View's child.
I want to make them parallel. but I couldn't find the contents about controlling another tag, not a child. In this code, I used setState, then I couldn't control another the below
.
Of course, I tried Fragment tag, but it didn't render anything.
How could I do implement this function? Please help me!
...ANSWER
Answered 2022-Feb-12 at 18:17Firstly 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.

I try to remove some data using the thin client data streamer (.NET apache ignite) but i end up with an exception:
DataStreamer can't remove data when AllowOverwrite is false.
My problem is when i try to change AllowOverwrite to true it is not respected.
...ANSWER
Answered 2022-Feb-02 at 12:16You 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 have a big problem. I have a video streamer site. The site has public and private videos, private videos can be seen after purchase.
Here you can see the directory structure:
...ANSWER
Answered 2022-Feb-03 at 15:41I 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.
Something like this:
QUESTION
I wrote a simple webapp for a huge amount of streamers. The streams are stable but audio/video not showing up.
Maybe you have a clue why.
See https://github.com/enexusde/Maven-Many-Videomeeting-RTC-OnlineServlet3.0
To start the app simply write mvn
in the console, all goals are used from the maven defaultGoal.
Then start two browser tabs having the url http://localhost:8080/vc/ .

Answered 2022-Jan-10 at 15:43I'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:
- 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. Usingif (self.peerConn.iceGatheringState === "complete")
ref fixes part of the problem. With this change Receiver sees the Sender's video. - From Receiver side you create answer and send back SDP immediately. ICE candidate collections starts after you call
createAnswer()
orcreateOffer()
. So you are sending SDP without any ICE candidates.
After you fix this other issue is that on Sender side there are noonAddStream
andstreamEventsChangedHandler
handlers. Thus Sender never gets to set received stream to correspondingelement.
- 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). RTCPeerConnection.onaddstream
is deprecated. UseRTCPeerConnection.ontrack
property- 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 configuretomcat7-maven-plugin
in pom.xml to serve pages on HTTPs. Steps to setup HTTPs are in the README.md file. - 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.
- 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.
- 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.
- 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.

Answered 2022-Jan-08 at 03:21if 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
