#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. Here is the command line: {{{ /root/ffmpeg_sources/ffmpeg*/./ffmpeg -stats -report -i http://streaming.streamonomy.com/ElectricFM -c:a copy -content_type audio/mpeg -f mp3 icecast://source:mypass@x.x.x.x:8000/mystream }}} and here is the output: {{{ root@vs4063:~# /root/ffmpeg_sources/ffmpeg*/./ffmpeg -stats -report -i http://streaming.streamonomy.com/ElectricFM -c:a copy -content_type audio/mpeg -f mp3 icecast://source:mypass@x.x.x.x:8000/mystream ffmpeg started on 2015-03-23 at 03:01:01 Report written to "ffmpeg-20150323-030101.log" ffmpeg version 2.6.1 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1) configuration: --prefix=/root/ffmpeg_build --extra- cflags=-I/root/ffmpeg_build/include --extra- ldflags=-L/root/ffmpeg_build/lib --bindir=/root/bin --enable-gpl --enable- libass --enable-libfdk-aac --enable-libfaac --enable-libfreetype --enable- libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libaacplus --enable-nonfree libavutil 54. 20.100 / 54. 20.100 libavcodec 56. 26.100 / 56. 26.100 libavformat 56. 25.101 / 56. 25.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 11.102 / 5. 11.102 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 3.100 / 53. 3.100 Input #0, mp3, from 'http://streaming.streamonomy.com/ElectricFM': Metadata: icy-br : 128 icy-description : ElectricFM plays today's dance hits! icy-genre : Electronic Dance Pop icy-name : ElectricFM.com - America's Real Dance! icy-pub : 1 icy-url : http://www.electricfm.com StreamTitle : KYGO f/ CONRAD - FIRESTONE Duration: N/A, start: 0.000000, bitrate: 128 kb/s Stream #0:0: Audio: mp3, 44100 Hz, stereo, s16p, 128 kb/s Output #0, mp3, to 'icecast://source:mypass@x.x.x.x:8000/mystream': Metadata: icy-br : 128 icy-description : ElectricFM plays today's dance hits! icy-genre : Electronic Dance Pop icy-name : ElectricFM.com - America's Real Dance! icy-pub : 1 icy-url : http://www.electricfm.com StreamTitle : KYGO f/ CONRAD - FIRESTONE TSSE : Lavf56.25.101 Stream #0:0: Audio: mp3, 44100 Hz, stereo, 128 kb/s Stream mapping: Stream #0:0 -> #0:0 (copy) Press [q] to stop, [?] for help size= 2093kB time=00:02:13.95 bitrate= 128.0kbits/s video:0kB audio:2093kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.016237% }}} [[Image(http://ffmpeg.gusari.org/download/file.php?id=103)]] In winamp first track is original and second transcoded..

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.

#4591: attachments mjpeg are discovered wrongly as video stream and therefore h264 encoding is broken -------------------------------------+------------------------------------- Reporter: TheoMeister | Type: defect Status: new | Priority: important Component: avformat | Version: Keywords: attachments | Blocked By: video | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Encoding with libx264 broken since https://github.com/FFmpeg/FFmpeg/commit/511585ce7f7272e5069ef011d6be5f073d2… - reverting this patch makes it working again as before as the attachments are just copied and not h264 encoded (which is not desired).

#4175(swresample:new): Dolby Pro Logic II / Dolby matrix downmixing level balance
by FFmpeg 26 Dec '24

#4175: Dolby Pro Logic II / Dolby matrix downmixing level balance -------------------------------------+------------------------------------- Reporter: ranutso | Type: defect Status: new | Priority: normal Component: swresample | Version: 2.4.4 Keywords: downmix | Blocked By: surround stereo dplii | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Hello guys. I am trying to downmix a 5.1 audio to 2.0 (stereo) using the audio resampler filter "matrix_encoding=dplii". The resulting stereo audio presents some audio level bias towards the right speaker when there is more than one active channel on the surround stream. That is, it seems that the audio volume on the right speaker is higher than it should be. This is, of course, using a test signal where all surround channels produce the same sound at the same volume. How to reproduce: {{{ % ffmpeg -i ChID-BLITS-EBU-Narration441-16b.wav -ac 2 -filter:a "aresample=matrix_encoding=dplii" dplii.wav ffmpeg version 2.4.4 Copyright (c) 2000-2014 the FFmpeg developers built on Dec 4 2014 14:13:11 with Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn) }}} You may freely obtain the surround test file I used on the command above from Fraunhoffer's website. Direct link to the surround wave file: https://www2.iis.fraunhofer.de/AAC /ChID-BLITS-EBU-Narration441-16b.wav Fraunhoffer's page where that file's URL is located: https://www2.iis.fraunhofer.de/AAC/multichannel.html If you analyze both the surround input file and the resulting stereo wave file on Audacity, for example, you will notice that by 19 seconds into the audio stream all channels are active with a test signal. The same point in time on the resulting DPL-II downmixed shows a "higher volume" on the right speaker. This effect is even more noticeable by 22 seconds when they change the test signal. It is interesting to note that in the initial seconds of the file, when a male's voice is announcing each channel individually, I could not notice this right speaker bias. The channel downmixing in that segment sounds correct. This effect is very noticeable on sound tracks with very active surround channels, they all seem to be stronger on the right speaker. Thank you. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4175> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
