I am trying to make a media explorer using the vlc-python library and tkinter. But I keep getting multiple errors. There errors occur in seemingly random order and only after pressing Left or Right. Pressing these buttons multiple times quickly sometimes causes the program to crash. Folder contains only images and videos. I am just including the unique errors :-
[000001e7a8e0b2a0] cache_read stream error: cannot pre fill buffer
[000001e7ae098ee0] mjpeg demux error: cannot peek
[000001e7ae286d30] direct3d11 vout display error: SetThumbNailClip failed: 0x800706f4
[000001e7b6be89f0] avcodec decoder: Using D3D11VA (Intel(R) HD Graphics 5500, vendor 8086(Intel), device 1616, revision 9) for hardware decoding
[h264 @ 000001e7a90b1040] get_buffer() failed
[h264 @ 000001e7a90b1040] thread_get_buffer() failed
[h264 @ 000001e7a90b1040] decode_slice_header error
[000001e7ae0fcbc0] direct3d11 vout display error: SetThumbNailClip failed: 0x800706f4
[000001dceaa2c890] mmdevice audio output error: cannot initialize COM (error 0x80010106)
Sometimes when I play videos, the playback continually lags and the following error is logged every time it lags,
[h264 @ 000001e7a90b1040] get_buffer() failed
[h264 @ 000001e7a90b1040] thread_get_buffer() failed
[h264 @ 000001e7a90b1040] decode_slice_header error
