Sensoray 2224 Windows - Manual (Page 74)

FAQ
Q1) Can the 2226 record one file and decode another at the same time?
A1) The 2226 is half duplex. Only one operation (encode/decode) may be performed at a time.
Q2) I need to pause the video. Why does the pause button in GraphEdit not work?
A2) The hardware does not support pausing of the stream. If pause is required, it may be possible to
construct a custom callback function to drop packets. At this time, Sensoray does not provide support
for such a feature. The recommended way to support pause is to record with separate clips.
Q3) I can't play back the recorded file in Windows media player on XP?
A3) XP and Vista do not necessarily have the H264 decoders to decode the stream. The recorded stream
may be played back with WMP under Windows 7. A player that works under XP is VideoLan.
Q4) What are the adapter inputs in the demo application?
A4) An optional termination board is available for the 2226 (2226-TA) to provide S-Video and an extra
composite video channel. This does not apply for the boxed 2226S unit.
Q5) Why do the image snapshots show 2 images.
A5) The S2226_SnapshotToFile and S2226_SnapshotToFileW functions work in conjunction with
S2226_SetMergeType. For maximum flexibility in the API, the user is given full control over how the
fields are presented. Change the merge type in the demo application to merge the fields into one frame.
