[FFmpeg-user] Possible bug in TEE muxer.

[Alex Molon]

Update.

Well... I'm trying with this command:

# ffmpeg -v verbose -i udp://226.45.23.147:2001 -c:v h264_nvenc -c:a aac -strict 2 -f tee -map 0 [f=mpegts:hls_segment_filename=sftp://compliance:complitest@localhost/home/auser/test/test.ts]sftp://compliance:complitest@localhost/home/auser/test/test.m3u8

And the result is always the same:

[tee @ 0x556de1794140] No option found near "//compliance:complitest at localhost/home/auser/test/test.ts]sftp://compliance:complitest@localhost/home/auser/test/test.m3u8"
[tee @ 0x556de1794140] All tee outputs failed.

I've tried with single, double and triple escape before the ":" signs (how suggested in https://trac.ffmpeg.org/ticket/5692 regarding something similar) but the result is always the same :(

Same happens if I try to use the ftp:// protocol.

Could you show us the complete, uncut console output (but blank out the passwords, please)?

I can find no indication whatsoever that ffmpeg supports ssh:// URLs.

I'll try to reproduce once I understand how to use ssh://. Perhaps if you add "-loglevel verbose", ffmpeg might show you how it interprets the options you are passing.
