Hello, I am converting single video to multibitrate. Let say if you upload video of 720p bitrate then i am generating video of different bitrate like 360p,240p etc. But, If you have already uploaded video before my implementation then that original video should play. I am generating dynamic smil file and providing that smil file when video plays. Now,If there is no video found in different bitrate then original video (uploaded video) should play. What should i do for that? Is there any way to achieve this? Can I get video bitrate from stream? because what i think , I have generated video in different bitrate and append that bitrate at the end , so what i will do i check if file exist which name ended with \_240p,\_360p etc. then play that video else play original video and for that i need to set original bitrate which i will get from stream. Please help me to get bitrate from the coming stream. Thanks. ---

Hi, If these are VOD files then you can query the file using a tool such as ffprobe (part of the ffmpeg suite) which will show the bitrate. Regards, Paul
