nginx RTMP to HLS : FFMPG error when trying multiple bitrate output [on hold]
28 mai 2014, par user3685074I’m currently trying to convert my RTMP Livestream into a HLS with 3 quality-settings.
I followed this guide
I’ve compiled my own FFMPEG and it’s working if I just convert 1 file.
It seems libx264 isn’t able to do multiple encodings at the same time ?I’m using these command :
exec /usr/local/bin/ffmpeg -i rtmp://localhost/src/$name
-c:a libfdk_aac -b:a 32k -c:v libx264 -b:v 128K -f flv rtmp://localhost/hls/$name_low
-c:a libfdk_aac -b:a 64k -c:v libx264 -b:v 256K -f flv rtmp://localhost/hls/$name_mid
-c:a libfdk_aac -b:a 128k -c:v libx264 -b:v 512K -f flv rtmp://localhost/hls/$name_hi 2>>/tmp/ffmpeg.log;this is the output :

FFmpeg/FFplay directshow and blackmagic
21 janvier 2016, par max246I got a BlackMagic intensity pro 4k capturing card, which is working fine with the express tool, I can see the live feed and record, but after I tried different stuff from what I found online to make ffplay/ffmpeg working, I ended up to have just a black screen.
I have checked if all the versions of my ffmpeg files were eanable-decklinnk, I have compiled the latest one with the latest version of the api, but still I get a black screen instead of the actually feed.

By running the command line above, I can only see a black screen but not actually errors.
