I encountered an error as shown below, I wonder if it is a camera encoding problem
You can set it with the --input-codec=h264
command-line option, or via the options dict in Python: https://github.com/dusty-nv/jetson-inference/blob/master/docs/aux-streaming.md#python
It should match the codec that the RTSP stream already uses though
ok,I will try this,thank you very much!
Let me know if I should open a separate issue, but I thought it was related enough:
I'd like to know how to find the exhaustive list of options available for this dict. I'm not seeing where this dict is actually parsed in the code. For example, how do I use headless
? Should it be {'headless': True} or how can I find the proper syntax/naming for all these options?
Also noting that specifying h265 results in a video that cannot be opened by vlc or the system viewer. i.e.
This produces a working video:
input = videoSource("csi://0")
output = videoOutput("my_video.mp4", options={"codec": "h264"})
Whereas this does not:
input = videoSource("csi://0")
output = videoOutput("my_video.mp4", options={"codec": "h265"})
This is the code common to both (derived from your video-viewer.py, but using threading as I'm also trying to run a flask app beside it).
def video_loop():
numFrames = 0
while numFrames < 200:
# capture the next image
img = input.Capture()
if img is None: # timeout
continue
if numFrames % 25 == 0 or numFrames < 15:
Log.Verbose(
f"video-viewer: captured {numFrames} frames ({img.width} x {img.height})"
)
numFrames += 1
# render the image
output.Render(img)
# update the title bar
output.SetStatus(
"Video Viewer | {:d}x{:d} | {:.1f} FPS".format(
img.width, img.height, output.GetFrameRate()
)
)
# exit on input/output EOS
if not input.IsStreaming() or not output.IsStreaming():
break
input.Close()
output.Close()
if __name__ == "__main__":
x = threading.Thread(target=video_loop)
x.start()
Is it possible to specify the decoder format when jetson_utils gets the rtsp camera, such as h264, h265, and if so, how should I do it (python code)?
