Select an encoder (when used before an output file) or a decoder (when used before an input file) for one or more streams. codec is the name of a decoder/encoder or a special valuecopy(output only) to indicate that the stream is not to be re-encoded. For example encodes all video ...

Real-time Frames Mode:When no valid input is received on-video_sourceattribute, StreamGear API activates this mode where it directly transcodes video-frames(as opposed to a entire file), into a sequence of multiple smaller chunks/segments for streaming. In this mode, StreamGear supports real-...
