Most of user data unregistered SEIs are privated data which defined by user/ encoder. currently, the user data unregistered SEIs found in input are forwarded as side-data to encoders directly, it'll cause the reencoded output including some useless UDU SEIs. I prefer to add one option to enable/disable it and default is off after I saw the patch by Andreas Rheinhardt: https://patchwork.ffmpeg.org/project/ffmpeg/patch/AM7PR03MB66607C2DB65E1AD49D975CF18F7B9@AM7PR03MB6660.eurprd03.prod.outlook.com/ How to test by cli: ffmpeg -y -f lavfi -i testsrc -c:v libx264 -frames:v 1 a.ts ffmpeg -y -i a.ts -c:v libx264 -udu_sei 1 b.ts ffmpeg -y -i a.ts -c:v libx264 -udu_sei 0 c.ts # check the user data unregistered SEIs, you'll see two UDU SEIs for b.ts. # and mediainfo will show with wrong encoding setting info ffmpeg -i b.ts -vf showinfo -f null - ffmpeg -i c.ts -vf showinfo -f null - This fixes tickets #9500 and #9557.
