demoBebopVisioGUI.py problem #167

Open ZisisT opened 5 years ago

ZisisT commented 5 years ago

so I'm trying to run this script and I get this error:

[00007f96e6b71070] videotoolbox decoder: Using Video Toolbox to decode 'h264' [00007f96e6b71070] main decoder error: buffer deadlock prevented libpng error: Read Error [00007f96e6b71070] main decoder error: buffer deadlock prevented [00007f96e6b71070] videotoolbox decoder: Using Video Toolbox to decode 'h264' [00007f96e6b71070] videotoolbox decoder: vt cvpx chroma: 420v

Basically from what I can tell the VLC video playback is not working, the image is being saved tho. Any ideas as to what might this be? I've already updated libpng

it works fine. It just puts out a lot of information from VLC. the ffmpeg version does the same thing. Lots of output! But the images are fine.

I have this similar error in demoAnafiVisionGUI.py

Starting user vision thread user callback being called success from play call is 0 Created new TCP socket 35 for connection timeout - trying again [00007fc67804cb70] main decoder error: buffer deadlock prevented [00007fc67804cb70] avcodec decoder: Using NVIDIA VDPAU Driver Shared Library 460.91.03 Fri Jul 2 05:42:23 UTC 2021 for hardware decoding [00007fc6bc000be0] main video output error: Failed to grab a snapshot timeout - trying again timeout - trying again timeout - trying again ...

I was able to stream the video with the GUI only once, but after that, a black screen or the visionStream.jpg loaded on the first time is displayed. Is there any special installation process for vlc or ffmpeg? Also, demoAnafiVision.py seems to work fine and a lot of pngs are stored in ./pyparrot/images.
