gst-shark 0.7.1 does not create metadata file.

[tmbuckley]

This is similar to the problem I had before the gstreamer I am using is complicated, but was creating metadata file until i changed from nveglglessink to nvoverlaysink, and removing some queues.....

I guess you found where a unlinked pad was causing problems

I am in the performance tuning part of the project, and gst-shark not working along with only proctime working is making my job impossible.

Thanks

Hi @tmbuckley. I have a few hours to look into this today. Please let me know the following:

• Is this happening with gst-launch or with an custom app?
• Is this related to gst-shark 0.7.1.1 only proctime works, other tracers do not create data or meta files. #90 ?

Any more context you can share is helpful.

[tmbuckley]

1. this is happening with gst-launch
2. yes I am still having the same problem as gst-shark 0.7.1.1 only proctime works, other tracers do not create data or meta files. #90, only proctime tracers working nothing else.

I was limping along using proctime and my script will attach it, and then I started using nvoverlaysink instead of nveglglessink and gst-shark quit creating the metadata file.

Below is my shell script. the stalkercreatevideo and stalkertakepicture are glorified faucet function remotely turns on and off. to allow system to create video or picture on demand.

How is this going now?
Unfortunately, I have the same issue.

[tmbuckley]

I had to break it up, like the tee's cause the problem, so I ran three tests instead of one large test, just can't test the complete stream at one time.

Hello guys. I was finally able to reproduce this problem. I'm sill looking into why this happens, but in the mean time please set this variable GST_SHARK_FILE_BUFFERING=0 as a workaround. This will tell gst-shark to immediately flush data written to files.

@tmbuckley this is your pipe (without your proprietary elements) which originally failed:

Also, @nicesj do you mind testing this branch. It basically flushes the metadata at startup.

[jhatchett-logitech]

Is there any way to use the hotfix/flush-metadata-file-at-startup branch with Yocto meta-ridgerun?

I'm also facing this problem and would like to help get it merged.

This thread is a bit dated but I wasn't able to get anything working with deepstream on tegra until I implemented #110. Really useful tool, thanks for sharing!
