my Scene is, I receive rtsp and store video data in list, and put it into tx1 decode.
if more than 2 channel, the list store video is overflow(more than 100 frame will overflow), the video list I max store 100 frame.
Hi sunYe,
We also verified four offline decoding:

But I think the test result differs case by case. One factor of making difference between offline decoding and online streaming may be network bandwidth, but probably other users can share more experience.
Hi DaneLLL
I want to use tera_multimedia_api/sample/02_video_dec_cuda to get one frame picture.can you tell me how to do this. and how to use 02_video_dec_cuda to write a file.like this “./video_dec_cuda …/…/data/Video/321.h264 H264 -o ./”?
Please run ‘./video_dec_cuda --help’ to get usage in detail
Hi DaneLLL
-o Write to output file ,but can you tell me what the type file can be written right,the commonds like this “/video_dec_cuda …/…/data/Video/321.h264 H264 -o ./test.mp4”, the file is wrong ,i can’t read the file correctly.

The output file is YUVs. You have to open via YUVviewer.
Hi,DaneLLL
I found 02_video_cuda_dec can only decode h264/h265 files; now i want to decode rtsp stream form an ipcamera realtime. I don,t know how to recieve rtsp stream with 02video_cuda_dec,you can give me some advice?
tegra_multimedia_api supports low-level h264/h265 decoding. For rtsp, you have to implement yourself.
You also can leverage gstreamer frameworks.
