Recorded video and audio files are not playing

[uzenith360]

Hi,

I've been having quite a painful time recording my ip camera rtsp stream, the recorded audio/video files arent playing. Please i need some help.

I'm using a windows 10 x64 machine.

Thanks so much.

I noticed that some of the last files before the timeout (in the code example) could play, the rest couldnt

[uzenith360]

While running one of the files that didnt play through ffmpeg, i get the following error: "moov atom not found". Could the issue be from the way the file was closed?

Was this resolved??

No it wasnt. I tried experimenting with ffmpeg and i got the mp4 recorded files, but it was with the command line and quite unwieldy. I'm trying to work out a cleaner way to achieve that maybe with the an npm ffmpeg module or spawning an ffmpeg process anytime i need to record my ip camera rtsp stream. I used the following command line arguments with ffmpeg; ffmpeg -i rtsp://192.168.0.103/live/ch00_1 -f mp4 -t 20 -c:v libx264 -preset veryfast -c:a aac summary4.mp4 -hide_banner - rtsp://192.168.0.103/live/ch00_1 is my ip camera live rtsp stream and summary4.mp4 is the name of the output mp4 video file, -t 20 specifies that the video should be 20 seconds long. You can get more info from the follow links [https://www.bugcodemaster.com/article/convert-videos-mp4-format-using-ffmpeg], [https://www.bugcodemaster.com/article/how-extract-and-join-video-files-using-ffmpeg]. Cheers!

At a point i realised the issue with the node-rtsp-recorder was that it wasnt ending the mp4 files properly. The mp4 files need some metadata information in order to play but the module was apparently closing the files without including those information hence the files it generated couldnt be played.

I figured this out. I will make a pull request. The correct tags are needed.

Ok, thank you very much!

I tryed to fix, but I have the problem again, my file is corrupted

[kraiymbek]

my solution: in record.js replace kill stream method to killStream() { this.writeStream.stdin.write('q') } and

get child process to

getChildProcess(fileName) { var args = ['ffmpeg', '-rtsp_transport','tcp','-i', this.url] const mediaArgs = this.getArguments() mediaArgs.forEach((item) => { args.push(item) }); args.push(fileName) console.log("args", args.join(' ')) return childProcess.exec(args.join(' '), function(err, stdout, stderr) {}) }

[leodesigndev]

one quick fix is to change output format on recorder.js

replace -- return '.mp4'

with ++ return '.mov'

the problem could be rooted to a codec issue with .mp4

[lakshaydulani]

@leodesigndev ur solution didnt work for me :(

[lablist]

Maybe someone will need it, my gist. Tested only under windows 10

• make sure the ffmpeg command is available from the console
• ... other requirements

the .mp4 file was corrupted, I tried changing it to .mkv and it worked. You can try to change in file /node_modules/node-rtsp-recorder/src/helpers/recorder.js and edit in getExxtension() function, change .mp4 file name to .mkv getExtension(){ if (this.categoryType === 'audio') { return '.avi'
} if (this.categoryType === 'image') { return '.jpg' } return '.mkv' }

Thanks your so much!

this module just copy raw rtsp encoding, it is not mp4, I think the point is just to record the stream. To play the file must be encode first to let say mpeg

ffmpeg -i recorded.mp4 -f mpegts -c:v mpeg1video playable.mp4

it works for me
