publish srt stream with special streamid

My FFmpeg version and built message:

=================================================
My FFmpeg command line:
ffmpeg -re -stream_loop -1 -i input.flv -c copy -f flv "srt://localhost:9000?streamid=test_stream?key1=value1&key2=value2"

My problem:
I have a sepcial streamid like "test_stream?key1=value1&key2=value2", when I publish stream with SRT by using this special streamid, ffmpeg will truncate it to "test_stream?key1=value1", I lost "&key2=value2"

I see the source code in libavformat/libsrt.c, FFmpeg will try to find the special argement in srt url.
Can I use "srt://localhost:9000?streamid="test_stream?key1=value1&key2=value2"" instead of "srt://localhost:9000?streamid=test_stream?key1=value1&key2=value2" or any other solution?

Thanks.

I had test the curent FFmpeg git head version, it have the same problem.
My command line:

ffmpeg -re -stream_loop -1 -i input.flv -c copy -f mpegts "srt://localhost:9000?streamid=test_stream?key1=value1&key2=value2"

This is likely fixed in 86128bd07a8634fb4a19c1bab616bc16ce0567d3, after that commit you should be able to use any streamid by urlencoding it properly.

Reopen if it still does not work.
