That tells you to configure things to install into /usr/local (which is
a good idea), but have you then configured pkg-config to look in
/usr/local/lib/pkgconfig as well?  Often it won't look in the
/usr/local prefix by default.

I can't remember how to configure it off the top of my head but the
instructions will only be a Google away.

Cheers,
Adam.

Re: [FFmpeg-user] ERROR: zimg >= 2.7.0 not found using pkg-config

2022-01-14 Thread Matt C 
Only real info I could find is
https://github.com/rdp/ffmpeg-windows-build-helpers/issues/291
[https://opengraph.githubassets.com/f9e2dd9c904f9070a3052cb8def7049c02742cbf4b69f7ec09810d0a83f3469d/rdp/ffmpeg-windows-build-helpers/issues/291]
[WORKAROUND] ERROR: zimg >= 2.7.0 not found using pkg-config · Issue #291 · 
rdp/ffmpeg-windows-build-helpers · 
GitHub
I tried to do a clean build today from newly cloned repo and ran across this 
issue with zimg. I found an earlier issue that mentioned zimg and a similar 
error, but that was in reference to v2.6.0 of zimg. It seems the dependency is 
now v...
github.com

I cannot find a zimg version 2.7.0 anywhere.  In the work around above is says 
to:



Temporary fix:

Change line 624 of cross_compile_ffmpeg.sh from

do_git_checkout https://github.com/sekrit-twc/zimg.git zimg_git 
c1689d4b9abbf4becadcbd4f436e2f3b2bf1c2f1

to

do_git_checkout https://github.com/sekrit-twc/zimg.git zimg_git 
8e87f5a4b88e16ccafb2e7ade8ef454aeac19094

and run cross_compile_ffmpeg.sh again,

This will update libzimg to this commit (and to V2.7.x)

But pretty sure the sekrit-twc/zimg git is for Windows, I am on Ubuntu 20.04..

In usr/local  I have:
bin  etc  games  include  lib  man  sbin  share  src  srs

In /usr/Bin:
ffmpegklvanc_eia708  klvanc_scte104 klvanc_util
ffprobe klvanc_genscte104  klvanc_smpte12_2  meson
klvanc_afd  klvanc_parse   klvanc_smpte2038

In /usr/Include: just libklvanc folder

In  /usr/local/lib: libklvanc.a  libklvanc.la  python2.7  python3.8

Not seeing a pkg-config file anywhere..

Re: [FFmpeg-user] Anyone using FFplayout? With Decklink..? ..ffmpeg argument help

2022-01-14 Thread Matt C 
Got FFplayout working, but can't seem to get my ffmpeg argument quite right..

I have ffmpeg compiled good and can play out the Decklink SDI 4k board fine, 
using this file and line:
https://www.dropbox.com/s/ujyna1dx3bhs7p4/720ts_6DK01H_tru720og.ts?dl=0

ffmpeg -i /home/matt/VideoTests/720ts_6DK01H_tru720og.ts -pix_fmt yuv420p -f 
decklink -vcodec v210 "DeckLink SDI 4K"

The same file is streaming fine out ffplayout rtmp and can be viewed in VLC 
with:
rtmp://192.168.1.xx/live/stream

In ffplayout there are 2 fields I need to get right, ffmpeg_param and 
stream_output..

Currently trying:

ffmpeg_param:

-c:v mpeg2video -g 1 -b:v 58982.4k -maxrate 9000k -bufsize 18000k -pix_fmt 
yuv420p -c:a s302m -strict -2 -ar 48000 -ac 2 -f mpegts

stream_output:

-flags +global_header -f flv rtmp://localhost/live/stream -pix_fmt yuv420p 
-vcodec v210 -f decklink "DeckLink SDI 4K"

===
The defaults are:

ffmpeg_param:
-c:v libx264 -crf 23 -x264-params keyint=50:min-keyint=25:scenecut=-1 -maxrate 
1300k -bufsize 2600k -preset medium -profile:v Main -level 3.1 -c:a aac -ar 
44100 -b:a 128k

stream_output:
-flags +global_header -f flv rtmp://localhost/live/stream

If you have not tried ffplayout, it is pretty awesome..

Apologies in advance, I know it's not a 100% ffmpeg question but hoping maybe 
someone will have some ideas..  Thanks!!

I have it installed from the Docker set up but cannot get anything to play from

Not much info on the Git page.  Thanks!

Re: [FFmpeg-user] Anyone using FFplayout? With Decklink..? Python Script

2022-01-14 Thread Matt C 
Found the output page. 
https://github.com/ffplayout/ffplayout_engine/wiki/Outputs

Anyone ever use a Python script/ file to play ffmpeg with an output function?

Thanks!
