I don't think its fair to shoot this down, its a simple but valid tidy up work. I find typos and such when browsing code distracting and readability important down the road. Not everyone's first language is English and grammar correction may not come instinctively. Thank you for the contribution J

Re: [FFmpeg-devel] Captions SCC

I believe I have sorted out the embed/extract issues I encountered into a formatting issue with the .scc file and lack of eia-608 codec for embedding captions. It is possible this might be a result of an oversight regarding drop frame or non drop frame time codes with some part of the chain that h

Hi, Thanks for your reply. I'm trying to fix some issues with hls. I happened to see this typo. Since I saw in the ffmpeg documentation that cosmetic changes should be kept in separate patches, so i submitted it first. Thank you for your advice, I will try my best to submit more important pat

Re: [FFmpeg-devel] Captions SCC

Partial reply: FFmpeg's CC decoder is actually pretty decent for pop-on CC but produces non-compliant ASS that needs postprocessing. ASS can cover and render the pop-ons quite well, but the fundamental limitation with representing EIA608 with ASS is that ASS does not allow arbitrary positioning AN

I suspect WebVTT became the modern CC format because... - It is natively supported by the HLS and DASH specifications - https://developer.apple.com/documentation/http-live-streaming/hls-authoring-specification-for-apple-devices - https://reference.dashif.org/dash.js/latest/samples

[FFmpeg-devel] [PATCH 1/2] lavc/vvc: Fix slice map construction for small subpics

In the case pps_subpic_less_than_one_tile_slice is called, the subpicture is smaller than the tile and so there are multiple subpictures in the tile. Of course, then, not all the subpictures can start in the top-left corner as the code before the patch does. Patch fixes this, so each subpicture s
