Need help to compile FFmpeg with MSVC tools
30 janvier 2018, par AntwaneI need to compile FFmpeg on Windows 10 using MSVC 2017 compiler. I followed some guides from :
- https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC
- https://www.ffmpeg.org/platform.html#Microsoft-Visual-C_002b_002b-or-Intel-C_002b_002b-Compiler-for-Windows
- https://pracucci.com/compile-ffmpeg-on-windows-with-visual-studio-compiler.html
I installed current stable version of MSYS, fixed link.exe and use of PATH environment, installed
make diffutils gcc pkg-config
and downloaded c99-to-c89, nasm, and inttypes.hI think my environment is now correctly set up, I ran MSYS shell from MSVC Command prompt and have everything reachable.

make: *** Aucune règle pour fabriquer la cible « ffbuild/library.mak ». Arrêt.Sorry for the french wording, I don’t know how to tell MSVC print its output in english. Basically, the error means :
Makefile:47: target « qt-faststart » doesn't match the target pattern
make: *** No rule to make target « ffbuild/library.mak ». Stopped.Side notes :
$ tree ffbuild
ffbuild
├── config.fate
├── config.log
├── config.mak
└── config.shThat’s right, library.mak were not generated into ffbuild, but I don’t know why, and configure script didn’t output any error message...
Does anybody can help me to find out what am I doing wrong ?
Edit :
make distclean
doesn’t help$ make distclean

ffmpeg options to stream to Youtube
24 octobre 2022, par David GoncalvesPlease bear with me as I don't really understand most of the commands behind ffmpeg.


I am using this code to live stream from a raspberry 4B with a USB Logitech C920 to YouTube :
ffmpeg -re -f s16le -i /dev/zero -f v4l2 -thread_queue_size 512 -codec:v h264 -s 1920x1080 -i /dev/video0 -codec:v copy -acodec aac -b:v 128k -g 60 -f flv rtmp ://a.rtmp.youtube.com/live2/[key]


The streaming works but I get the following error in the command line :
Non-monotonous DTS in output stream 0:0 ; previous : 0, current : -167 ; changing to 0. This may result in incorrect timestamps in the output file.


I also get this error in Youtube studio :
Please use a keyframe frequency of four seconds or less. Currently, keyframes are not being sent often enough, which can cause buffering. The current keyframe frequency is 8.0 seconds. Note that ingestion errors can cause incorrect GOP (group of pictures) sizes.
Any help ?
