[FFmpeg-user] NV12 devices/players compatibility

Hi All, I know this is not strictly related to FFMPEG but please don’t insult me  I normally transcode using ffmpeg with h264_nvenc, that produces a NV12 output, then I convert it in pix_fmt yuv420p before chunking in HLS/DASH But this conversion, when I do “all in hardware” transcoding in

Re: [FFmpeg-user] How to have a secure UDP BroadCast

You simply cannot. UDP delivery is not meant to do that. There are other protocols that support authentication  If you provide a little bit more about what are your needs I can suggest some. Alex -Original Message- From: ffmpeg-user On Behalf Of hassan shatnawi Sent: 02 October 2017

[FFmpeg-user] FFMPEG endlessly increases memory usage over time with HLS packaging.

Hi All, I would like to use ffmpeg as live HLS ABR packager and use /dev/shm to store playlist and chunks in RAMDISK. But unfortunately I’ve noticed that ffmpeg constantly increase the memory used until it saturates it. the script does basically this steps: mkdir -p /dev/shm/live/test cd

Re: [FFmpeg-user] HLS setting NAME in EXT-X-MEDIA

Thanks Ted, It's exactly what I'm doing. I'm rewriting the master playlist on the fly with NGINX. The strange thing is that audio_1 and so on are arbitrary names set by ffmpeg by itself so I really don't understand if this is a expected behaviour or some flaw in the muxer design or a bug.

[FFmpeg-user] HLS setting NAME in EXT-X-MEDIA

Hi Guys, Does anybody know If there is a way to set a specific value of NAME in EXT-X-MEDIA with the HLS muxer? My command line is: /usr/src/ffmpeg-4.2.2/ffmpeg -hwaccel cuvid -c:v h264_cuvid -i INPUT.ts \ -filter_complex
