[FFmpeg-user] How to escape a URL passed to the underlying dash muxer via tee

[Dennis Mungai]

Hey there,

How should one escape a URL passed to the underlying DASH muxer via tee?

Here's the string I use from within a BASH script setting the muxer options:

DASHOPTS='use_fifo=1:fifo_options=attempt_recovery=1:f=dash:seg_duration=6:window_size=6:utc_timing_url="https://time.akamai.com/?iso"'

Doing so results in this:

[tee @ 0x55746a001640] No option found near "//time.akamai.com/?iso"
[tee @ 0x55746a001640] Slave muxer #9 failed: Invalid argument,
continuing with 9/10 slaves.
