Cannot run sample on own .h264 file

Autonomous Vehicles DRIVE PX 2 DriveWorks

When calling the free space sample with the videos provided by nvidia it runs without any problems.
The video out.h264 runs without any problem when using ffplay.
Any suggestions what could be the Problem?

Dear Sebastian6j1z2,

Please refer to below link for your topic. Thanks.

Dear SteveNV

I rechecked the properties and they seem to be perfectly equal.

Also, my problem is not that the output when processing the video is bad but that I can’t process the video at all. As soon as I call the sample_freespace_detection it crashes with the error shown in my initial post.

Best regards
Sebastian

Dear Sebastian6j1z2,

Weird, I ran the sample with several video files even raw type file without any error.

sudo ./sample_freespace_detection --video=…/./data/samples/sfm/triangulation/video_0.h264
sudo ./sample_freespace_detection --video=…/./data/samples/raw/rccb.raw
sudo ./sample_freespace_detection --video=…/./data/samples/laneDetection/video_lane.h264
sudo ./sample_freespace_detection --video=…/./data/samples/stereo/rightRect.h264
sudo ./sample_freespace_detection --video=…/./data/samples/cameraBlindness/reencoded_20160808blk_50_blind.h264

Could you provide us the video file you used? Thanks.

Dear SteveNV,

the video files show potentially sensitive information. Could I give it to you via PM?
If an official channel is necessary for this I can also open a bug report for it.

Thanks.

Dear SteveNV,

never mind that. We got it running on a different system.
There has to be a problem with my system.

Still thanks for your time!
