Re: [FFmpeg-user] ffmpeg cuvid not transcoding properly

It seems like again I hit the wall. While one mpeg2 source works with the mpeg2_cuvid option, the other gives me troubles. ffmpeg -threads 1 -vsync 1 -hwaccel cuvid -c:v mpeg2_cuvid -deint 1 -drop_second_field 1 -i 'http://0.0.0.0:46007' -c:v h264_nvenc -vb 1000k -preset:v medium -c:a aac -ac 2 -a

The good news is that all the required pieces appear to exist; the bad news is that no one has yet (to my knowledge) glued them together to make a functional solution. Here’s someone who has gotten very close: https://github.com/szatmary/libcaption/issues/55#issuecomment-525688953 "I would like

Danke für deine Hilfe! Yes, I have mice in my yard :-( They can actually invade a weak hive and wreak havoc! Do you remember approximately when you saw it? YT automatically archives the footage twice a day, so I’d like to review it and see the mouse! Thank again! > On Nov 20, 2019, at 7:11 AM

Re: [FFmpeg-user] Add soft subtitles to YouTube Stream Now?

That's a very interesting subject (to me at least). I would like to embed automatic (or human generated, depending on the budget) subtitles to help hearing-impaired people grab most of the talk in our conference. I am producing H.264 and sending it (for the time being) to YouTube, so your request i

Hi there, First of all, sorry for being vague, I don't have ffmpeg command line options yet, I'm just trying to know if I'm totally mistaken, or if my idea could be implemented quite safely/easily. I'm currently thinking of getting rid of YouTube for streaming within the company I work for (becau

Re: [FFmpeg-user] Add soft subtitles to YouTube Stream Now?

I noticed your Youtube streams only last a day or so. I have a Python script I made that keeps the ffmpeg process sending to Youtube. I have 5 IP cameras going to youtube and they have been going about 9 months without the stream ending. Anyways, if you want I could show you how the script works. Y
