Audio video duration matching for infinite dash loop pseudo live
19 janvier 2020, par Massimo VantaggioMay I ask help to understand how to match audio and video duration during ffmpeg encoding for a concatenation of videos destined to an infinite loop mpeg dash transmission (mp4box).
My issue happen during ffmpeg encoding :
first step for audio encoding and timebase uniformity of each video before the concat/encode process :
ffmpeg -y -i "$f" -c copy -video_track_timescale 90k -c:a aac -b:a 384k -ar 44100 -ac 2 -shortest -af aresample=async=1 ../buffer/${NAME}_buffer.mp4
Then concat/encode process in order to get total duration in seconds multiple of closed GOP
for example : cutting 373.5 duration to obtain 372.000 duration :ffmpeg -f concat -safe 0 -y -i list.txt -loop 1 -i ../logo/logo.png -c:a copy -c:v libx264 -x264opts keyint=$GOP:min-keyint=$GOP:no-scenecut -bf 0 -r $FPSC -b:v 4800k -maxrate 9600k -bufsize 19200k -profile:v main -crf 22 -filter_complex "[0:v][1:v]overlay=main_w-overlay_w-10:10,scale=1920:1080,setsar=1" -t $TOTDUR 1080set.mp4
the result
VIDEO FORMAT CONTAINER DURATION:
372.000000
VIDEO STREAM DURATION:
372.000000
AUDIO FORMAT CONTAINER DURATION:
372.006000I need help to understand why the audio duration counts 6 ms more than video duration and how to fix it.
I read about loop_stream should help ?
Thanks a lot !Below the videos info :

Use ffmpeg to stream live content to azure media services
19 mars 2018, par DadicoolI’ve been trying to stream content to azure media services using ffmpeg as it’s one of the options described here : http://azure.microsoft.com/blog/2014/09/18/azure-media-services-rtmp-support-and-live-encoders/
My command is :
ffmpeg -v verbose -i 300.mp4 -strict -2 -c:a aac -b:a 128k -ar 44100 -r 30 -g 60 -keyint_min 60 -b:v 400000 -c:v libx264 -preset medium -bufsize 400k -maxrate 400k -f flv rtmp://nessma-****.channel.mediaservices.windows.net:1935/live/584c99f5c47f424d9e83ac95364331e7
I have made sure that the streaming endpoint has one active streaming unit, I also made sure that the channel is actually Ready and I even get it to start streaming (which makes a PublishURL available).
When I execute the ffmpeg command to start streaming, I keep getting the following error :
