ffpyplayer/player/core.c: No such file or directory, flv and metadata support #86

Hi!

I have a problem with ffpyplayer. I always getting segmentation fault. After quick debug mode with gdb I got more useful error, but still I am not able to fix this by my own.

I am using docker image: openvisualcloud/xeon-ubuntu1804-media-ffmpeg:latest. From perspective ffmpeg everything is working, because I was able to run all of my needed commands with proper decoders/encoders.

ffpyplayer version: compiled from latest version from github

Example code:

from ffpyplayer.player import MediaPlayer

filename="<flv or simple mp4 isnt' working too>"

player = MediaPlayer(filename=filename, ff_opts={'f': 'flv'})

Error:

(gdb) run script.py
Starting program: /.try/bin/python script.py

I also tried with mp4 file, but I get the same error above.

I know this should be another Issue, but this is quick questions: Is ffpyplayer able to read flvs and return metadata? Is ffpyplayer support HEVC/h265 or this library support every format that is supported by ffmpeg?

After some digging I figure out that I should install this package like this: pip install -e . I run my example scrit once again and this time it generated new error:
