The parameter is client-side, because it hits one of two endpoints (old or new). Use Plex/Web and you can see it hit the new endpoint: ``` /video/:/transcode/universal/start.m3u8?path=http%3A%2F%2F127.0.0.1%3A32400%2Flibrary%2Fmetadata%2F514586&mediaIndex=0&partIndex=0&session=cdsu8elxfkc323xr&protocol=hls&offset=0&fastSeek=1&directPlay=0&directStream=1&videoQuality=100&videoResolution=1920x1080&maxVideoBitrate=20000&subtitleSize=100&audioBoost=100&X-Plex-Token=xxx&X-Plex-Client-Identifier=yyy&X-Plex-Product=Web+Client&X-Plex-Device=Mac&X-Plex-Platform=Chrome&X-Plex-Platform-Version=27&X-Plex-Version=1.0.0&X-Plex-Device-Name=Plex%2FWeb+(Chrome)&X-Plex-Account=x&X-Plex-Username=yyy ``` ---

Elan, I rearranged you URL for better readability: /video/:/transcode/universal/start.m3u8? path=http%3A%2F%2F127.0.0.1%3A32400%2Flibrary%2Fmetadata%2F514586& mediaIndex=0& partIndex=0& session=cdsu8elxfkc323xr& protocol=hls& offset=0& fastSeek=1& directPlay=0& directStream=1& videoQuality=100& videoResolution=1920x1080& maxVideoBitrate=20000& subtitleSize=100& audioBoost=100& X-Plex-Token=xxx& X-Plex-Client-Identifier=yyy& X-Plex-Product=Web+Client& X-Plex-Device=Mac& X-Plex-Platform=Chrome& X-Plex-Platform-Version=27& X-Plex-Version=1.0.0& X-Plex-Device-Name=Plex%2FWeb+(Chrome)& X-Plex-Account=x& X-Plex-Username=yyy What happened to the "old" interface with time, key, hash -\>X-Plex-Access-Key? Is there no need for this anymore? Did it slip into X-Plex-Token? How are now the client's capabilities communicated regarding filetype and/or codecs? Short... I am looking for some documentation on how to fill those parameters. Is there a specification around? ---

Hi i used a little bit tcpdump to find out the settings for the universal transcoder. maybe someone can use it:-) /video/:/transcode/universal/start.m3u8? subtitleSize=100 path=http%3A%2F%2F127.0.0.1%3A32400%2Flibrary%2Fmetadata%2F14434 session=\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* audioBoost=100 protocol=hls directStream=1 directPlay=0 3g=0 videoResolution=1920x1080 maxVideoBitrate=20000 videoQuality=100 X-Plex-Device=\*\*\*\*\*\*\*\*\* X-Plex-Token=\*\*\*\*\*\*\*\*\* X-Plex-Client-Platform=\*\*\*\*\*\*\*\* X-Plex-Device-Name=\*\*\*\*\*\*\*\*\*\* X-Plex-Model=\*\*\*\*\*\*\*\*\* X-Plex-Platform=\*\*\*\*\*\*\* X-Plex-Client-Identifier=\*\*\*\*\*\*\*\*\*\*\*\*\* X-Plex-Product=\*\*\*\*\*\*\*\*\* X-Plex-Platform-Version=6.1.3 X-Plex-Version=3.1.3 420x240, 320kbps videoResolution=420x240&maxVideoBitrate=320&videoQuality=30 576x320, 720 kbps videoResolution=576x320&maxVideoBitrate=720&videoQuality=40 720x480, 1,5mbps videoResolution=720x480&maxVideoBitrate=1500&videoQuality=60 1024x768, 2mbps videoResolution=1024x768&maxVideoBitrate=2000&videoQuality=60 1280x720, 3mbps videoResolution=1280x720&maxVideoBitrate=3000&videoQuality=75 1280x720, 4mbps videoResolution=1280x720&maxVideoBitrate=4000&videoQuality=100 1920x1080, 8mbps videoResolution=1920x1080&maxVideoBitrate=8000&videoQuality=60 1920x1080, 10mbps videoResolution=1920x1080&maxVideoBitrate=10000&videoQuality=75 1920x1080, 12mbps videoResolution=1920x1080&maxVideoBitrate=12000&videoQuality=90 1920x1080, 20mbps videoResolution=1920x1080&maxVideoBitrate=20000&videoQuality=100 ---

I am looking for some documentation on how to fill those parameters. Is there a specification around?   We've left the time, key, hash parameters off this new endpoint (for now, at least). No spec on the format/codec, but should be mostly anything supported by ffmpeg. ---

Hi elan, one more question. the old transcoder had the option for secondspersegment. you mentioned in another thread that this is not needed anymore. My problem is, that my client on enigma2 does not start playback if the amount of segements in the m3u8 files exceeds a special amount. Now i am faced with the same problem with the new transcoder that if i use a higher quality playback does not start. is there a way to set the seconds again or can you give me another hint how to avoid to much segements in the m3u8 to have the user with enigma2 their plex expierience in higher quality :-) ---

Unfortunately there is not way to manually set that with the new transcoder ☹ ---
