video is fine but no audioįfmpeg -i -c copy -tag:v hvc1 output.mp4 However, what you save in storage costs may be eaten (several times over, sometimes) by processing costs so it is a business decision as much as a technical decision.I use this to convert ts to mp4. It is definitely possible to do 'Just In Time' transcoding - this is what Live Streams have to do anyway. Being able to schedule it when you have spare computing resources or can allow it plenty of time to complete is often the most cost effective approach. The main reason for not doing 'Just In Time' transcoding also is that transcoding is processor intensive. Note, that the transcoding and splitting and even packaging can be combined in a single step, with some cloud encoding services offering exactly that service, however, 'Just In Time' packaging is still very common. The packaging is then applied 'Just In Time' when the user or client requests the video. 'Package' into the particular streaming protocol you want for the device you are streaming to, which is usually HLS or DASH these days.Īssuming the video is not a live stream, it is common for the transcoding and splitting to be done initially when the video is first ingested into the system.split the video into a segmented or fragmented format to allow HLS or MPEG-DASH streaming.

transcode the video into however many bit rate versions you want.When you start with a single bit rate MP4 and want to serve it as a HLS or MPEG-DASH (usually just called DASH) stream you typically do a number of steps:
