ffmpeg failed to pull local rtmp stream
3 septembre 2019, par edhuI’m relatively new to this workflow and this might be a simple problem to solve. However, I haven’t found answers that matched exactly with my question. I’ve set up my nginx server with rtmp module and for testing purposes I used the following command to publish my stream :
ffmpeg -re -i -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/show/stream
After that, I launched up my application which is supposed to read the stream from the nginx server and it failed at
avformat_open_input(&ctx, szFilePath, NULL, NULL);
The returned error code is -5 and it signifies I/O issue. The
szFilePath
I passed in isrtmp://localhost/show/stream
and I assume this will automatically work since it works when I tried to play some mp4 sample files online. I also triedrtmp://localhost:1935/show/stream
and vice versa. I could view the stream being played in VLC but I can’t open it in the code. I’m not really sure what happened here. I feel like this isn’t necessarily a complicated issue but I don’t know where to start looking for possibles causes. I’d appreciate the help. Thanks ! -

fluent ffmpeg => how to trim and concate parts of video into one output file without writing many output files. Make a most efficient solution
30 avril 2024, par Shreyansh GuptaI'm currently working on a online video website and i need to make a quick preview of videos using random timestamps and duration of the video.


Suppose the video is of 15 min then i want to cut out some parts like ->


1. from 00:00:40 take out next 2s 
2. from 00:01:20 take out next 2s 
3. ... and so on until the new video becomes 15s



How can i do this with fluent-ffmpeg in the nodejs project


Can i get the most efficient way of doing this without writing many output files and then concating them separately and removing then later


Only concating the trimmed videos in one output file and save when it is done.


I also came through a solution that uses complex filters but i don't know how to use it


ffmpeg("video.mp4")
 .complexFilter([
 ....// some filters here

 ])
 .on('end', function () {
 console.log('files have been merged and saved.')
 })
 .on('error',function (err){
 console.log(err)
 }
 .saveToFile("output.mp4")```
