Compiling custom FFMPEG
25 novembre 2019, par ArttuI need to compile ffmpeg from source for CentOS. The goal it to convert MP3 and WAV to FLAC. I tried to compile ffmpeg with this guide : https://trac.ffmpeg.org/wiki/CompilationGuide/Centos
and it worked fine, but took approximately 20min and compiled a bunch unnecessary things, even thought I did not used next options as recommended in guide, but used :PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
--prefix="/opt/tmg/ffmpeg_build" \
--pkg-config-flags="--static" \
--extra-cflags="-I/opt/tmg/ffmpeg_build/include" \
--extra-ldflags="-L/opt/tmg/ffmpeg_build/lib" \
--extra-libs=-lpthread \
--extra-libs=-lm \
--bindir="/opt/tmg/ffmpeg_build/bin" \
--enable-gpl \
--enable-libfreetypeMy question is what do I need for MP3 and WAV to FLAC and how do I compile just that part ?
I found in configuration
--disable-all
option, but what do I have to enable ?Thanks in advance.

FFmpeg WebM AV1 Support
6 septembre 2018, par Matt McManisWith FFmpeg how can I use
AV1
codec in awebm
container ?I get the error :
Only VP8 or VP9 video and Vorbis or Opus audio and WebVTT subtitles are supported for WebM.
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:0 --
However Wikipedia says WebM supports AV1.
https://en.wikipedia.org/wiki/AV1
AV1 is intended to be able to be used together with the audio format Opus in a future version of the WebM container format for HTML5 web video
Or can FFmpeg simply not encode this new version ?
My settings :
ffmpeg -y
-i "C:\Users\Matt\video.mp4"
-c:v libaom-av1 -strict experimental
-cpu-used 1 -crf 28
-pix_fmt yuv420p
-map 0:v:0? -map_chapters -1
-sn
-c:a libopus
-map 0:a:0?
-map_metadata 0
-f webm
-threads 0

ffmpeg -i "concat:/storage/emulated/0/Recordings/oneone.mp3|/storage/emulated/0/Recordings/twone.mp3" -c copy /storage/emulated/0/Recordings/concated.mp3
but get this error :
"concat:/storage/emulated/0/Recordings/oneone.mp3|/storage/emulated/0/Recordings/twone.mp3": No such file or directory
Even though the both files exist in the directory. I have written this command according to the documentation : https://trac.ffmpeg.org/wiki/Concatenate#protocol
