Is there any Python driven video player that runs on Tinker Board

Hi,

Seems VLC doesn't work on Tinker Board, do you guys know if there is any video player that can be controlled by Python and workable on Tinker Board (Edge R)?

Thanks

Arnold

hello @Arnold Chan, 

for tinker edge r, there's built in"media player" available in the tinker os image for media streaming, however it's not python driven. 

if you're using other players, it may be laggy as tinker edge uses cpu to decode and read video.

I think you can use gstreamer from python. I have just started exploring this myself so I am not sure yet.

Here is my version of python-gstreamer dvr. You need to install the python-gst bidnings though:

pythong dvr -records 60s video - I have to fix the pipeline though because the clips are really big. 2+ gigs per minute

#this is just to get the date and time into the output filename
now = datetime.now()
date_time = now.strftime("%m-%d-%Y_%H-%M-%S")

# the same pipeling you would use in gst-launch, starting from v4l2.... Note the ' #encompassing the whole pipeline, except the +str(date-time)+ which is excluded. Use #the plus to make python add a string with the date.
