[FFmpeg-user] FFmpeg is shutting down when concating segmented files and outputting to UDP
hello, I am new to this community, i have used ffmpeg in my server in which i have live streams and i am segmenting them and then storing after a while i concat the segmented files and then output these to udp. Firstly i got a problem of open file limit which i had solved but then again i got a problem in which the ffmpeg shut down automatically in 2-3 days, time is not random. I am using xeon processor with 16 gb ram, ffmpeg version 3.4. earlier i have noticed that cpu utility increases but exactly don't knw the reason. i have also generated the log file with -report option but these log files are generated in order of 100s of gbs but i have managed to grab some end file lines and there is no error message before quitting, i also tried hardware accel qsv but i am still getting same problem. i have doubt that this is bug in ffmpeg. Please help me with solving this issue.

So if I want to retain the interlacing from the vob file, I should use MBAFF. What is the ffmpeg option for this? Which is the de-interlacing method, libx264 uses by default? I'm interested in that, because I imagine, that it would be better for the quality to retain the interlacing, i.e. then the video player is able to write 50 half-frames per second to the output display, which provides better quality than 25 merged progressive frames per second. Does my assumption hold? But unfortunately I do not know, if my video (DVD-R recorded from a VHS cassette) originally was telecined from an analogue celluloid film or was produced directly on video tape (which should be true interlaced). Any idea, how I can detect this? It was a low budget production in 1982. -Ulf ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

It's only important that I have the clut and the picture combined in one 16-bit picture, so that they can be processed simultaneously. By the way xstack is much better than hstack because it accepts pictures of different height. Problem solved!

Re: [FFmpeg-user] problems consuming live single file hls
Since hls is a streaming format i would actually expect this to work. >>> It does work for "multi file" which is what hls is meant to be. >> Byte-range is part of the standard (see >> https://tools.ietf.org/html/draft-pantos-http-live-streaming-08#section-3.4.1), >> so single file is as much "meant to be" as multi-file afaict. > But the playlist does not change or does it? Ah, I think now I understand where we missed each other: Yes it does! That is one of the central points in HLS: Video is produced in segments (either in separate files or by appending to one file, but in either case playable individually). After a segment is produced it is "published" via the playlist by appending some lines to it. To do this atomic the file is usually copied, appended to, and then "swapped" back in via rename. The single file hls implementation in ffmpeg somehow fails to properly order these things, i.e. segments become visible in the playlist before they are fully written, breaking the standard hls consumer pattern. > >>> If you use single file, I don't see how the behaviour can be >>> different, you can reproduce it using mpegts on your local >>> file system. >> What do you mean?
