Problems video playing in some android devices (version 4+) but not in others
5 juin 2014, par anquegifollowing the settings for video in android developers, http://developer.android.com/guide/appendix/media-formats.html I encoded a video using ffmpeg like this :
ffmpeg -i gravityTrailer.mp4 -y -f mp4 -vcodec libx264 -profile:v baseline -acodec aac -strict -2 -profile:a aac_low -b:v 500k -ar 44100 -b:a 128k -ac 2 -r 30 -s 480x360 output_hq.mp4
which corresponds on sd highquality in table 2 from android developers (link above).
Then i put this video in a server and use the class android.media.MediaPlayer to reproduce it from that URL like this
https://cloudapp.somedomain.com/bmftvideos/output_hq.mp4
The problem is that the video is played on android version 4+
you can see the video on :
LG G2,
Sony xperia Syou cannot see the video on :
Samsung galaxy S4,
BQ (spanish) aquaris 4.5And I don not know why
this is the ffmpeg output :

Use ffmpeg to stream live content to azure media services
9 juin 2016, 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 :
