E-Series failed to set constant bitrate

Description

Seems to happen with context stream on e-series encoder. The range on constant bitrate mode could be set to invalid ragne of 32-1024 instead of 32-8192. So with bitrate set to something like 2048 would the bitrate out of range error and failed to set. Also in this case, the stream setting would also drop to “constant quality” setting.

Tested Version

8.0.0.102418

<br>

Steps to reproduce

  1. E-Series(tested unit 00-50-F9-E8-09-64 10.16.13.96)
  2. add context stream for input 1
  3. set context stream to h264/constant quality/ apply
  4. change the context h264 stream to “Constant Bitrate” and 2048kbps
  5. change context stream to jpeg and apply.
  6. change context stream back to h264 and apply with constant bitrate set to 2048kbps.

Expected result

Constant bitrate is correctly applied.

<br>

Actual result

– the bitrate range is set to 32-1024

– failed to set constant bitrate

– Rate Control selection is set to “Constant Quality”
