Guest asrequested Posted June 29, 2019 Posted June 29, 2019 Luke, a quick heads up for cc in mpv. For some reason, they don't work with hwdec copyback modes. I've been trying to nail this down, and finally discovered that is why I couldn't get them to work. I'll have to update my mpv issue report. I thought the problem was deinterlacing, but I was wrong.

Guest asrequested Posted June 30, 2019 Posted June 30, 2019 (edited) I just confirmed this with the official release of mpv. I've updated the mpv issue report. One thing to keep in mind is that lachs0r has changed the default behavior for hwdec of MPEG2. The official release will use hwdec for MPEG2, but for future releases he has disabled it. It can be re-enabled by the user. This means that MPEG2 will by default be software decoded, and the cc will work. Luke, you should keep this is mind with your future builds. Some people may have issues with software decoding, keeping in mind they will also likely need deinterlacing. https://github.com/mpv-player/mpv/commit/3dd59dbed06a55eed00ad68d0a953f39188e3647 Edited July 1, 2019 by Doofus

Guest asrequested Posted June 30, 2019 Posted June 30, 2019 Any reason why it can't do hwdec and cc You can, but not copyback. Example, you can use d3d11va, but not d3d11va-copy. The way cc is incorporated into the video, means that changing the file affects the cc. So I think what may be happening is when the stream is copied to the system memory, it's being changed in some way, which is affecting the cc. 1
BillOatman 596 Posted July 1, 2019 Posted July 1, 2019 Can anyone verify if CC works with the Apple TV client. I have a hard of hearing friend who is heavily invested in the Apple ecosystem including Apple TV, and want to know if I can suggest this to her yet or not. Thanks!
Guest Posted September 7, 2019 Posted September 7, 2019 Is supporting CC/subtitles embedded in OTA TV targeted yet for a specific release of Emby Theater? We're hoping to get to that soon. Thanks. Any progress for Emby Theater desktop? This is a showstopper for us before considering a premiere subscription. Thanks.

I forgot get back to you on this Odd I don't see that option in Emby Theater or by Web App unless you refer D3D (Windows 8+) ? which doesn't work not even in direct steam as far I can tell seem to only have support external subtitle and not embedded subtitle and don't want spent a small fortune on a Nvidia Shield TV if I recall right that only way but then there no mobile support. Any progress for Emby Theater desktop? This is a showstopper for us before considering a premiere subscription. Thanks. Nope no at this time

That would be the option in the settings. But until Luke adds the CC option (it's being overridden), it won't work. And you can choose any decoding option other than the hardware copyback modes.
samuelqwe 317 Posted January 9, 2020 Posted January 9, 2020 Are closed captions still planned for iOS, tvOS and other platforms? I used to use CCExtractor as a recording post-processing script to extract CC from recordings, but I have not been able to find a way to use it since switching my server to Unraid.

SHSPVR 123 Posted January 9, 2020 Posted January 9, 2020 This has now been fixed. Where I don't see CC icon
Guest asrequested Posted January 12, 2020 Posted January 12, 2020 It's not in Theater, yet. I was just reporting that the issue in mpv where cc wasn't working with hardware copy modes, has been fixed. Theater is in the process of being rebuilt. So maybe we'll see an option for them when that is finished?

Luke 42077 Posted April 8, 2020 Posted April 8, 2020 We have a little more work to do with closed captioning but we're getting there.
dovedescent7 3 Posted April 8, 2020 Posted April 8, 2020 We have a little more work to do with closed captioning but we're getting there. Well i guess its still possible, if i can open recordings in vlc.

SHSPVR 123 Posted April 8, 2020 Posted April 8, 2020 Theoretically, these should work in Android TV. Can you get me a sample file? Actually there two EIA 608 and 708 it can very across different tv station I pm you the file link
SHSPVR 123 Posted April 8, 2020 Posted April 8, 2020 Theoretically, these should work in Android TV. Can you get me a sample file? There No Roku, iPad, iPhone, Emby Theater nor in the Web App and there far larger vast majority of user that have Roku over Android after all 1
Guest Posted August 9, 2020 Posted August 9, 2020 My yearly Schedules Direct subscription (used with WMC) ends in Oct and I'm again evaluating a subscription to Emby for the Windows desktop app to replace it. But it's a no go without Live TV closed captioning working via Direct Play (a transcoding solution wouldn't be acceptable). @Luke , is there a real chance this will be provided by Oct?
Luke 42077 Posted December 3, 2021 Posted December 3, 2021 Universal closed caption support is coming:
