recording - Should I record my stream in HLS or mp4 format in Ant Media Server?

Question

I am using Ant Media Server for live streaming and I want to record the streams. I know I can do it by enabling mp4/webm recording. But HLS seems to be a good alternative according to this. What is the most effective way?

Answer 1

mp4/webm recording is the easiest way to record your streams. As you said you just need to enable. However, in case of disk capacity fullness or unexpected stop in the stream, mp4.tmp_extension file could not be converted to the final mp4 file. Then you may lost whole record.

If you disabled HLS file deletion, you would have the records as HLS chunks. Moreover, you can convert them at the end of the stream to mp4. Therefore, if you will record long-duration streams the mp4 file size will be large and if disk capacity is full then you lost everything. If you record as HLS then you may lost few parts after disk is full.
