I'd just like to point out that although @chenjinli may not be able to build FFmpeg with libsrt as shared libraries, it is perfectly possible to do so.

I build FFmpeg as both shared and static every day. I would not like people to be put off from using SRT because an answer to an issue says it cannot be used in a shared library context.

Just a note regarding this useful guide: link.
And I think "strp" is not SRT, but a different protocol (FFmpeg guide). So please check your build.

thanks @maxsharabayko . i have found the reason. we can not build ffmpeg both with --enable-libsrt and --enable-shared. once i delete the --enable-shared option, it runs ok

Thanks @chenjinli. Made a note in the SRT cookbook.

I just cannot get past this ffmpeg ./configure error
ERROR: srt >= 1.3.0 not found using pkg-config
even though pkg-config --modversion srt returns 1.4.2
Does anyone have an idea where to start? I have spent about a week on it so far, it should be simple I know

Hi @robynjayqueerie
Your issue is probably related to your environment somehow.
Could you try to get help in the #development channel on Slack?
