[FFmpeg-user] Not able to open URL using avformat_open_input

[m.kamalasubha m.kamalasubha]

Hello all,
I tried to open URL using avformat_open_input API function.
Initially, I got a warning like,

*Using network protocols without global network initialization. Please use
avformat_network_init(), this will become mandatory later.*

After initializing avformat_network_init(), I am getting a negative return
value for avformat_open_input() function call.

*INPUT URL:* https://mnmedias.api.telequebec.tv/m3u8/29880.m3u8

Can anyone please help me to find the issue?

Regards,
Kamalasubha M
