#4300: Segmenter duplicating audio stream from previous segments -------------------------------------+------------------------------------- Reporter: hdezela | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: git- Keywords: hls, | master ssegmenter | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When using ssegmenter to produce an HLS group from RTMP (calling ffmpeg from nginx-rtmp with exec_push) each segment has the audio from (segment - 3) under the original audio. segment0 = audio0 segment1 = audio1 segment2 = audio2 segment3 = audio3+audio0 segment4 = audio4+audio1 This keeps layering up to something like segment 100 having its audio plus the additive audio of all the -3 segments behind it.

#4292: Add ProRes444XQ Codec support in ffmpeg (enhancement) -------------------------------------+------------------------------------- Reporter: gregba | Type: Status: new | enhancement Component: | Priority: wish undetermined | Version: git- Keywords: prores | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: Apple introduced a new ProRes flavour some month ago. At the moment ffmpeg is not capable of this I can run those files, by changing all the 4CC codes in the file from ap4x to ap4h. So I guess is is just a minor fix in the ffmpeg source code.

#4293(avformat:new): avformat: optionally write an approximate duration ahead-of-time if possible

#4293: avformat: optionally write an approximate duration ahead-of-time if possible ----------------------------------+--------------------------------------- Reporter: 11rcombs | Type: enhancement Status: new | Priority: wish Component: avformat | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- This would be useful when writing a format like MKV or MP3 that has a duration in the header that we currently avoid writing until the entire file is finished, for cases where we're writing to an un-seekable output (like a pipe), or where the output is going to be read before it's finished being written. Having a duration, even if it may be somewhat inaccurate, can improve behavior in some players. For ffmpeg.c, this value would be based on the corresponding input streams' durations. The easiest way to implement this would probably be setting AVFormatContext::duration, but I wouldn't be surprised if there were cases where setting the individual AVStream::durations would make more sense. We could also send it as metadata, either at the format or stream level. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4293> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4118(ffmpeg:new): mpegts: allow to set service_type in SDT

#4118: mpegts: allow to set service_type in SDT ----------------------------------+--------------------------------------- Reporter: dhead666 | Type: enhancement Status: new | Priority: normal Component: ffmpeg | Version: 2.4.3 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- AFAIK When muxing any stream to mpegts the service_type field in the SDT always set as tv (not sure about the hex value, maybe 0x01). It would be useful to be able to set the value to something else as radio. I'm not sure if adding only one choise is a good idea (meaning being able to choose only tv or radio) as I see there are multiple related values for radio as 0x02, 0x07 and 0x0A (same goes for tv), so it might be best to just add all the values from the "Service type coding" table (table 87 in http://www.etsi.org/deliver/etsi_en/300400_300499/300468/01.13.01_40/en_300… ). Another approach would be to automatically set the service_type as radio if there's only an audio stream (again, the question is which value exactly). My personal interest with this is to be able to add internet radio stations correctly to tvheadend. I pipe mpegts of internet radio station (originally HLS stream) from ffmpeg to tvheadend as described at https://tvheadend.org/projects/tvheadend/wiki/Custom_MPEG-TS_Input and by entering the following to tvheadend: pipe:///usr/bin/ffmpeg -loglevel fatal -i http://103fm-s.nsacdn.com/103fm_LiveRadioRepeat/_definst_/smil:LiveRadio.sm… -acodec copy -metadata service_provider=STRING -metadata service_name=STRING -f mpegts -tune zerolatency pipe:1 The stream recognized in tvheadend as tv channel and not radio because ffmpeg set service_type as tv.
