The Datastead RTSP/RTMP/DirectShow Source Filter SDK can capture RTSP, RTMP, UDP, TCP, MMS, HTTP streams, render the uncompressed audio and video streams, and can simultaneously save the native streams to MP4, MKV, AVI, FLV or MOV file without video transcoding.

The filter can:

- receive streaming sources in RTSP, RTMP, RTP, HTTP, UDP, RTP, MMS protocols,

- connect asynchronously to the URL without blocking the main thread (the filter graph receives a notification when the connection completes),

- decode the streams and exposes the uncompressed video and/or audio output pins,

- record at the same time the video streams in their native format without transcoding, directly to a file (MP4, FLV, MOV, AVI, or MKV file),

- encode the audio streams to PCM, MP3 or AAC, depending on the recording file name (e.g. H264/AAC for a MP4 recording),

- generate new files on the fly without loosing frames and without pausing/stopping/restarting the graph.

The filter includes internally the required multiplexers (MP4, FLV, MOV, AVI and MKV mux) and does not transcode to H264, it saves directly the native H264 samples to the file.
If the audio recording is enabled the audio stream is encoded to PCM, MP3 or AAC, depending on the format being recorded (e.g. H264/AAC for MP4).
