Hi,
I'm trying to save segmented files of a live stream. If I save a converted version of the stream (transcoded to webm in this example) everything works fine: ---------------------------------------------- # /usr/bin/ffmpeg -re -i http://evcv.mm.uol.com.br/band/terraviva/chunklist_w1904488612.m3u8 -map 0:v -map 0:a -acodec vorbis -strict -2 -ac 2 -vcodec libvpx -quality realtime -cpu-used 0 -b:v 600k -flags +global_header -f tee [f=segment:segment_time=900:segment_time_delta=1:reset_timestamps=1:strftime=1]/home/rodrigo/temp/teste+%Y-%m-%d_%H:%M:%S+terraviva.webm ffmpeg version 3.0.7-0ubuntu0.16.10.1 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 6.2.0 (Ubuntu 6.2.0-5ubuntu12) 20161005 configuration: --prefix=/usr --extra-version=0ubuntu0.16.10.1 --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --cc=cc --cxx=g++ --enable-gpl --enable-shared --disable-stripping --disable-decoder=libopenjpeg --disable-decoder=libschroedinger --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libpulse --enable-librubberband --enable-librtmp --enable-libschroedinger --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzvbi --enable-openal --enable-opengl --enable-x11grab --enable-libdc1394 --enable-libiec61883 --enable-libzmq --enable-frei0r --enable-chromaprint --enable-libx264 libavutil 55. 17.103 / 55. 17.103 libavcodec 57. 24.102 / 57. 24.102 libavformat 57. 25.100 / 57. 25.100 libavdevice 57. 0.101 / 57. 0.101 libavfilter 6. 31.100 / 6. 31.100 libavresample 3. 0. 0 / 3. 0. 0 libswscale 4. 0.100 / 4. 0.100 libswresample 2. 0.101 / 2. 0.101 libpostproc 54. 0.100 / 54. 0.100 Input #0, hls,applehttp, from 'http://evcv.mm.uol.com.br/band/terraviva/chunklist_w1904488612.m3u8': Duration: N/A, start: 39298.092733, bitrate: N/A Program 0 Metadata: variant_bitrate : 0 Stream #0:0: Data: timed_id3 (ID3 / 0x20334449) Stream #0:1: Video: h264 (Baseline) ([27][0][0][0] / 0x001B), yuv420p(tv), 320x240 [SAR 1:1 DAR 4:3], 25 fps, 29.97 tbr, 90k tbn, 50 tbc Stream #0:2: Audio: aac (HE-AAC) ([15][0][0][0] / 0x000F), 44100 Hz, stereo, fltp, 89 kb/s [libvpx @ 0x55a918487320] v1.5.0 Output #0, tee, to '[f=segment:segment_time=900:segment_time_delta=1:reset_timestamps=1:strftime=1]/home/rodrigo/temp/teste+%Y-%m-%d_%H:%M:%S+terraviva.webm': Metadata: encoder : Lavf57.25.100 Stream #0:0: Video: vp8 (libvpx), yuv420p, 320x240 [SAR 1:1 DAR 4:3], q=-1--1, 600 kb/s, 29.97 fps, 29.97 tbn, 29.97 tbc Metadata: encoder : Lavc57.24.102 libvpx Side data: unknown side data type 10 (24 bytes) Stream #0:1: Audio: vorbis, 44100 Hz, stereo, fltp Metadata: encoder : Lavc57.24.102 vorbis Stream mapping: Stream #0:1 -> #0:0 (h264 (native) -> vp8 (libvpx)) Stream #0:2 -> #0:1 (aac (native) -> vorbis (native)) Press [q] to stop, [?] for help frame= 2357 fps= 30 q=0.0 Lsize=N/A time=00:01:19.00 bitrate=N/A speed= 1x video:5826kB audio:1357kB subtitle:0kB other streams:0kB global headers:3kB muxing overhead: unknown Exiting normally, received signal 2. ---------------------------------------------- But if I try to save the original stream as it is (using copy) I get tons of warnings and a broken file with no audio and some freezing and jumping video: ---------------------------------------------- #

How can I save a segment version of a stream like this without renconding it?
