• FFMPEG RTSP stream to multiple output, one mp4 and also restream

  16 août 2022, par csonty

  I would like to seek your help with FFMPEG and how to use it properly on Windows and Linux. I have to get the camera RTSP stream and record it into 1 minutes segments and also stream at the same time.
I did try to stream it to rtsp, but it didn't work at all [f=RTSP]rtsp ://ipaddress:554/mystream , it stuck and did nothing.

  


  I did also try to add the -use_wallclock_as_timestamps 1 but it didn't do anything. I also tried to add the -flags +global_header, but not sure, how to add it into this script.

  


  I did try it on both Linux and Windows with the following commands (not sure how to create a bash script from it)

  


  Linux :
./usr/bin/ffmpeg -i 'rtsp://username:password@192.168.68.99:554/Streaming/Channels/101/' -c copy -f tee -map 0:v '[f=segment:strftime=1:segment_time=60]wwcam99-%Y-%m-%d_%H-%M-%S.mp4|[f=mpegts]udp://10.10.3.251:5555'

  


  Windows :
ffmpeg -i "rtsp://username:password@192.168.68.99:554/Streaming/Channels/101/" -c copy -f tee -map 0:v "[f=segment:strftime=1:segment_time=60]wwcam99-%%Y-%%m-%%d_%%H-%%M-%%S.mp4|[f=mpegts]udp://10.10.3.199:5555"

  


  It records the files and the stream can be viewed on the localhost (not sure why I cannot view from other machines even if the firewall is off, but it might be a network issue)

  


  This is the output with mostly error messages that I couldn't fix :

  Any help would be highly appreciated

  


• Concat video files using ffmpeg in individual subfolders with shell script [closed]

  18 août 2022, par Weatherdark

  I had a Windows script that would do what I want, but I switched my server to Unraid so now I need a new script. Anyway, enough backstory.

  


  I regularly have media that is named in a style like "Videoname CD(Number).ext". They get stored in subfolders called Videoname with a different folder for each video.

  


  What I need is a script that goes through each subfolder and creates a concat.txt file with the names of each video file ending in CD(number) in it, in numerical order, that will then call ffmpeg to concat the files using the concat.txt in each subfolder, placing the video file (named after the subfolder) into a folder like /mnt/User/Pool/Finished/Videofile. Then, hopefully it will delete the concat.txt file so I know which folders are finished with a quick look.

  


  I know the ffmpeg concat options for that part, I just have no idea what to use to make sure the resulting video file is named after the subfolder it came from.

  


  I could do this in Windows (albeit in a hacky, not very pretty way), but I have no idea how to accomplish this in Linux.

  


  As an example...

  


  


  /mnt/User/Pool/Concat/10.10.2022.0034.Recording/10.10.2022.0034.Recording
CD1.mp4
/mnt/User/Pool/Concat/10.10.2022.0034.Recording/10.10.2022.0034.Recording
CD2.mp4
/mnt/User/Pool/Concat/10.10.2022.0034.Recording/10.10.2022.0034.Recording
CD3.mp4
/mnt/User/Pool/Concat/10.10.2022.0034.Recording/10.10.2022.0034.Recording
CD4.mp4
/mnt/User/Pool/Concat/10.11.2022.0254.Recording/10.11.2022.0254.Recording
CD1.mp4
/mnt/User/Pool/Concat/10.11.2022.0254.Recording/10.11.2022.0254.Recording
CD2.mp4
/mnt/User/Pool/Concat/10.11.2022.0254.Recording/10.11.2022.0254.Recording
CD3.mp4
/mnt/User/Pool/Concat/10.11.2022.0254.Recording/10.11.2022.0254.Recording
CD4.mp4

  


  Put through ffmpeg to concat, results in files

  


  /mnt/User/Pool/Finished/10.10.2022.0034.Recording.mp4

  


  /mnt/User/Pool/Finished/10.11.2022.0254.Recording.mp4

  


  


  Hopefully that makes sense.

  


  Someone closed this because it wasn't "focused enough" and didn't focus on one thing... but there is ONLY one thing that it needs to do.

  


  I have no idea what they would want me to change to fix what isn't broken, so I fundamentally am at a loss. The script just needs to search through subfolders, create a concat.txt file and send that file to ffmpeg creating the new file, named after the folder, in a new location. That is literally as focused as I can make it.

  


• SetInodeAttributes error when creating a file inside bucket

  19 août 2022, par Turgut

  I've made a C++ program that lives in gke and takes some videos as input using ffmpeg, then does something with that input using opengl,finally it encodes those edited videos as a single output. Normally the program works perfectly fine on my local machine, it encodes just as I want it to with no warnings whatsoever. But I want it to encode that video directly to the cloud using a gcsfuse bucket. I've succesfully mounted the bucket and it seems to create the file at the start of my programs run. But when the run is over it's suppose to finish the encoding and finilize the video file. However when it reaches the end it gives off this error on the terminal where I run the gcsfuse command :

  


  2022/08/19 21:38:15.477586 SetInodeAttributes: input/output error, SetMtime: UpdateObject: not retrying UpdateObject("c36c2633-d4ee-4d37-825f-88ae54b86100.mp4"): gcs.NotFoundError: googleapi: Error 404: No such object: development-videoo-storage1/c36c2633-d4ee-4d37-825f-88ae54b86100.mp4, notFound

fuse: 2022/08/19 21:38:15.769659 *fuseops.GetInodeAttributesOp error: input/output error


  


  At the end I end up with a file with the same size as my desired output but with an invalid video with no frames in it.

  


  I'm using a service account to activate my bucket, I can read files just fine and my service account has every permission it needs, here is how I mount my bucket :

  


  GOOGLE_APPLICATION_CREDENTIALS=./service-account.json gcsfuse -o nonempty --foreground cloud-storage-name /media


  


  I'm using ubuntu 22.04
