#5419(avformat:new): HLS EXT-X-DISCONTINUITY tag is not supported

#5419: HLS EXT-X-DISCONTINUITY tag is not supported -----------------------------------+--------------------------------------- Reporter: xyq204101 | Type: enhancement Status: new | Priority: normal Component: avformat | Version: git-master Keywords: hls | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+--------------------------------------- Summary of the bug: I'm trying to read input from HLS and output to RTMP, this works fine if the HLS segments are all in one time sequence. However if the time changes e.g. segments generated from two video files, ffmpeg got error 'Non- monotonous DTS in output stream 0:1;'. According to the HLS documentation, EXT-X-DISCONTINUITY should be used when time sequence changes. (https://tools.ietf.org/html/draft-pantos- http-live-streaming-13#section-3.4.11) But I still got the same error after I added that tag to the m3u8 file. Look at hls.c file in libavformat, it doesn't handle EXT-X-DISCONTINUITY tag. How to reproduce: {{{ ffmpeg -re -i http://hls-server/playlist.m3u8 -acodec copy -vcodec copy -bsf:a aac_adtstoasc -f flv rtmp://rtmp-server/app }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/5419> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4566(ffmpeg:new): ffmpeg won't copy metadata ("StreamTitle") from audio live stream (transcoding)

#4566: ffmpeg won't copy metadata ("StreamTitle") from audio live stream (transcoding) ----------------------------------+------------------------------------- Reporter: easydoor | Type: defect Status: new | Priority: important Component: ffmpeg | Version: 2.6.2 Keywords: metadata | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+------------------------------------- It won't copy "StreamTitle" from input to output while transcoding input from mp3 to aac. I'm using version v2.6.1 compiled by me on ubuntu 14. I try simpliest transcoding with -c:a copy option and sending it to icecast v2.4.1 and as a client I'm using latest winamp and vlc. In booth player as title is showing only the mount point (in this case mystream) from icecast: {{{ icecast://source:mypass@x.x.x.x:8000/mystream }}} and not the StreamTitle from input file. Why and how can I just pass it from input to output? I don't think that problem is Icecast, because I try to stream with SAM Broadcaster and in Winamp I see updated StreamTitle in real time.

#3643: XYZ to RGB color space -------------------------------------+------------------------------------- Reporter: tteam | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: Keywords: more XYZ to | unspecified RGB matrix | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: XYZ to RGB colorspace conversion use only sRGB matrix and sometimes the conversion is deffected in red channel and the picture is dark. Hi all! Is it possible to add more color space matrix (in option) to XYZ to RGB conversion? Because the FFMPEG use only one matrix (sRGB) but lots of available, and best if the user can choose one. Because the problem is: sometimes the conversion is deffected the red is much more and the picture is dark. If possible please add some from this list. The default is the sRGB but optional the others.
