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!
