• ffmpeg - Can't stably save rtsp stream to file

  20 août 2022, par André Luís

  I'm trying to save the RTSP stream of this camera to file. However, at some point I'll get the following errors, which will stop the process.

  


  


  video:331639kB audio:5199kB subtitle:0kB other streams:0kB global
headers:0kB muxing overhead : unknown

  


  


  And a bunch of these, before the previous one :

  


  


  Non-monotonous DTS in output stream 0:1 ; previous : 5439375, current :
5439283 ; changing to 5439376. This may result in incorrect timestamps
in the output file.

  


  


  Here is the command I'm running :

  


  ffmpeg "rtsp://192.168.0.100:554/cam/realmonitor?channel=1&subtype=0" -c copy -f segment -segment_time 00:01:00 -reset_timestamps 1 -segment_format mkv -strftime 1 /home/user/.camera/recordings/2022/8/19/%H_%M_%S.mkv


  


  I've tried adding each of these parameters and they all together :

  


  -fflags +autobsf+genpts -y -threads 1 -use_wallclock_as_timestamps 1 -dts_delta_threshold 0 -rtsp_transport tcp -i


  


  ffprobe :

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

  18 août 2022, par Luka

  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) :

• 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 :

  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
