• 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

  


• 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

  


• how to remux/fix video file saved with testdisk that reports error "Invalid NAL unit size"

  I have deleted a video file from an SD card and then 'undeleted' it with tool called testdisk for Linux. It saved complete file (6Gb), but video seems broken (can't be played by any video players) and ffprobe reports :

  I'm no programmer, but have used ffmpeg a lot. How can I remux (or even re-encode) such file to fix this and make the file usable for further work ?

  


  I have created a 10seconds snippet with ffmpeg -i MVI_1399.MP4 -t 00:00:10 -c copy MVI_1399_10sec.mp4 for anyone to check. I also created a ten second snippet from a functioning clip from the same camera (I presume same codec parameters etc) :
