[Bug] transcoded HLS fails to stream

Hi, I develop plex player app, and with the latest Plex server version, transcode fails. the log says

[Req#12e868/Transcode/57251275-2B50-4643-86A9-AEF62937B500/6901370a-c5bc-4215-a72a-be3e77dd56db] Unrecognized option 'segment_copyts'.

along with

[Req#12e880/Transcode/57251275-2B50-4643-86A9-AEF62937B500/6901370a-c5bc-4215-a72a-be3e77dd56db] Error splitting the argument list: Option not found

and I’m assuming this fails to parse ffmpeg option `-copyts`.

"add-direct-play-profile(type=videoProfile&protocol=http&container=mp4,mov&videoCodec=h264,mpeg4,hevc&audioCodec=aac,ac3,eac3&subtitleCodec=mov_text,tx3g,ttxt,text,webvtt)+add-direct-play-profile(type=musicProfile&protocol=http&container=flac&audioCodec=flac)+add-direct-play-profile(type=musicProfile&protocol=http&container=mp4&audioCodec=alac)+add-transcode-target(type=videoProfile&context=streaming&protocol=hls&container=mp4&videoCodec=h264,hevc&audioCodec=aac,ac3,eac3&replace=true)+add-transcode-target(type=subtitleProfile&context=streaming&protocol=hls&container=webvtt&subtitleCodec=webvtt)+add-transcode-target(type=musicProfile&context=streaming&protocol=hls&container=mpegts&audioCodec=aac)+add-limitation(scope=videoAudioCodec&scopeName=*&type=upperBound&name=audio.channels&value=6&replace=true)+add-limitation(scope=videoCodec&scopeName=*&type=notMatch&name=video.codecID&value=dvhe&onlyDirectPlay=true)+add-limitation(scope=videoCodec&scopeName=*&type=notMatch&name=video.codecID&value=hev1&onlyDirectPlay=true)+add-limitation(scope=videoCodec&scopeName=*&type=upperBound&name=video.width&value=8192&replace=true)+add-limitation(scope=videoCodec&scopeName=*&type=upperBound&name=video.height&value=4096&replace=true)+add-limitation(scope=videoCodec&scopeName=*&type=upperBound&name=video.width&value=8192&onlyTranscodes=true&replace=false)+add-limitation(scope=videoCodec&scopeName=*&type=upperBound&name=video.height&value=4096&onlyTranscodes=true&replace=false)"

this is X-Plex-Client-Profile-Extra param I am currently using. When I send in empty string for X-Plex-Client-Profile-Extra, the media plays fine but subtitle is baked into the video.

Sorry I didn’t mean to jump into a bug report from someone writing software.
Seems odd no logs. :man_shrugging:
