Re: [FFmpeg-user] ffplay struggling with this station!
Well, I just tried that command you suggested, but it still skipped whenever it fetched a new TS. And it couldn’t be my connection speed as I have more than a Gbps internet speed. But this tells me that it must be the software versions, since you didn’t have any issues. I’ll update the software and let you guys know.

That probably means something like it’s’ playing 1 second in the past, so if something happens and it can’t keep up in realtime there’s still 1 second to fix it before it skips. That's exactly what it means, though I think the word "buffer" would be more appropriate. cache [noun]: a temporary storage space or memory that allows fast access to data. buffer [noun]: a storage device for temporarily holding data until the computer is ready to receive or process the data, as when a receiving unit has an operating speed lower than that of the unit feeding data to it. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Re: [FFmpeg-user] ffplay struggling with this station!
Ted, I did try without that buffer flag, but that had no effect. I’m going to try updating ffplay, and see if that helps. Also, I’ve noticed that vlc had a 1000 ms “network cache”, and I wonder if that had anything to do with playing that station flawlessly.

Hi, > I use the following command to play the station: > $ ffplay -nodisp -vn -fflags nobuffer -fflags discardcorrupt -flags low_delay > https://jrtv-live.ercdn.net/jrradio/englishradiovideo.m3u8 I think “-fflags nobuffer” tells ffplay not to buffer? So there will be nothing to play every time ffmpeg finishes playing a segment and only then starts fetching the next segment. But I also thought if you use -fflags multiple times without a plus sign before the flag only the last one was used, so I’m not sure. And I’m pretty sure low_delay is only a thing in some video decoders.
