Hi all Please help check an issue: When I sent date to rtmps server(facebook live). Connection will block after sent 10 packet. Below is the situation: 1 build: ./configure –enable-openssl && make && make install 2 connet to rtmp is ok. But rtmps is fail, BLOCK after sent out 10 packet. 3 if delete this line : ret = ffurl_read(rt->stream, &c, 1); and add: ret = AVERROR(EAGAIN); in function rtmp_write(), then every thing will be ok. I also found this line was added at this commit: https://github.com/FFmpeg/FFmpeg/commit/7dc747f50b0adeaf2bcf6413e291dc4bffa54f9a 4 my code is attached, for your reference.
I want to know if this is a bug, if not, how to fix this? Can I simply fix it as point3 said. Thanks!
