Hello,
We are trying to generate video with nullSrc and feed into Dei before encode. If scanFormat of nullSrc is progressive, the corresponding Dei's enableDeiForceBypass is set to TRUE.
[ nullSrc 2CH ] -> [ select ] -+-> [ Dei0 1CH ] -> + -> [ merge 2CH ] -> [ NSF ] -> [ IPC VPSS ] -> [ IPC Video ] -> [ Encode ] ...
+-> [ Dei1 1CH ] -> +
We notice that if channel 0 is progressive and channel 1 is lnterlaced, the output fps of channel 0 is around 16 (30 is expected). It is normal (fps 30) in other cases.
Is there any performance issue when two Dei links works on progressive and lnterlaced modes? Any idea to avoid the problem.
Thank you very much.
The experimental result as below:
ch0: progressive ch1: interlaced => fps: 16, 30 FAILED
ch0: progressive ch1: progressive => fps: 30, 30
ch0: interlaced ch1: interlaced => fps: 30, 30
ch0: interlaced ch1: progressive => fps: 30, 30
