[FFmpeg-user] FFMpeg stream audio problem
Hi, I have Debian Buster Stable and I installed the FFMpeg program. I would like to stream audio from the microphone of the soundcard to the local IP of this computer LAN card and other computer can connect through LAN to play the stream. My goal is to stream audio with lowest latency as possible. I know that Opus is better than mp3, I only want to find an operating method for me and test it first. I want to find the best method to stream audio with low latency, and less CPU usage, best quality is not important. I have plan to buy Raspberry Pi and use it for streaming with FFMpeg. I tried these two scripts to stream: #!/bin/sh ffmpeg -f alsa -i plughw:1 -acodec libmp3lame -ar 11025 -f rtp rtp://192.168.1.20:8000 #!/bin/sh ffmpeg -f alsa -i plughw:1,0 -acodec libmp3lame -ab 96k -ac 1 -re -f http http://192.168.1.20:8080 The scripts do not produce any error but stops after start immediately. Do you have any ideas? What is the problem? ffmpeg -devices output: Devices: D. = Demuxing supported .E = Muxing supported -- DE alsaALSA audio output E cacacaca (color ASCII art) output device DE fbdev Linux framebuffer D iec61883libiec61883 (new DV1394) A/V input device D jackJACK Audio Connection Kit D kmsgrab KMS screen capture D lavfi Libavfilter virtual input device D libcdio D libdc1394 dc1394 v.2 A/V grab D openal OpenAL audio capture device E opengl OpenGL output DE oss OSS (Open Sound System) playback DE pulse Pulse audio output E sdl,sdl2SDL2 output device DE sndio sndio audio playback DE video4linux2,v4l2 Video4Linux2 output device D x11grab X11 screen capture, using XCB E xv XV (XVideo) output device arecord -l output: List of CAPTURE Hardware Devices card 1: Generic [HD-Audio Generic], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Generic [HD-Audio Generic], device 2: ALC892 Alt Analog [ALC892 Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 log of the first script: ffmpeg version 4.1.4-1~deb10u1 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 8 (Debian 8.3.0-6) configuration: --prefix=/usr --extra-version='1~deb10u1' --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-lv2 --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared libavutil 56. 22.100 / 56. 22.100 libavcodec 58. 35.100 / 58. 35.100 libavformat58. 20.100 / 58. 20.100 libavdevice58. 5.100 / 58. 5.100 libavfilter 7. 40.101 / 7. 40.101 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 3.100 / 5. 3.100 libswresample 3. 3.100 / 3. 3.100 libpostproc55. 3.100 / 55. 3.100 log of the second script: ffmpeg version 4.1.4-1~deb10u1 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 8 (Debian 8.3.0-6) configuration: --prefix=/usr --extra-version='1~deb10u1' --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --arch=amd64 --enable-gpl --disable-stripping --enable-avresample --disable-filter=resample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libaom --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libcodec2 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libjack --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librsvg --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi

I created a 1500x1000 1000-image set: Sequence_000.png ->
Sequence_999.png. This loads fine using at the start of the command line:
ffmpeg -i Sequence_%03d.png
This will also work if the sequence numbers are inside the filename:
ffmpeg -i 0191107-154%03d-214.png
But if you rename the first 5 files to: _Sequence_000.png ...
_Sequence_004.png it will fail because the first file starting with
Sequence is now Sequence_005.png.
Renaming _Sequence_004.png -> Sequence_004.png will allow the remaining
995 files in the sequence to load.
If you can not batch rename the sequence to start from 00 or if it is a
non-contiguous list because you deleted some damaged/missing images, you
can tell FFMPEG to load a list of filenames. This has to be in a
particular 1 or 2-line format (if including image duration).
For example, I've deleted the first 83 images, substituted a
Replacement.png, and the remaining image names jump by 3. Then I created
a list of filenames.
To create such a list in Windows, I use create_list.bat, here designed
to look in the "Sequence Directory", beneath the current directory
("C:\test directory"), where the images files are situated, create a
2-line name-sorted list where the 2nd line is the duration in secs (1
frame at 25fps = 40ms), and then load this list in the associated text
editor so you can delete or move blocks, change durations etc., if required.
@echo off
SETLOCAL EnableDelayedExpansion
if exist mylist.txt del mylist.txt
for %%I in ("Sequence Directory\*.png") do (echo file '%%~fI' >>
mylist.txt & echo duration 0.04 >> mylist.txt)
start /i mylist.txt
The first 4 files in the list:
file 'C:\test directory\Sequence directory\Replacement.png'
duration 0.04
file 'C:\test directory\Sequence directory\Sequence_0083.png'
duration 0.04
file 'C:\test directory\Sequence directory\Sequence_0086.png'
duration 0.04
file 'C:\test directory\Sequence directory\Sequence_0089.png'
duration 0.04
If you decrease the duration below 0.04 @25fps FFMPEG will start to drop
frames. Conversely, if you go above 0.04, it will start to replicate frames.
To use this list:
ffmpeg.exe -f concat -safe 0 -i "C:\test directory\mylist.txt" -maxrate
3k -y "C:\test directory\Sequence directory"\map_video6.mpg

Aformat filter will not get you new channels in channel layout, you will need channelmap filter instead.

[FFmpeg-user] Help using find_rect
Hi, i am trying to use the feature find_rect. I have a video with a single colored area which i would like to detect. I have tested different colors (white, black, blue) without success. The box is never replaced in the video. The ffmpeg command i use is: ffmpeg -i input.mp4 -loglevel debug -report -vf find_rect=black-80.pgm,cover_rect=green.jpg:mode=cover output.mp4 For the ppm image I used imagemagick with different options. The last one I used is: convert -size 80x80 xc:black -depth 4 -colorspace gray -define png:color-type=0 -define png:bit-depth=4 input/black-80.pgm Thanks Regards Mike ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
