Transcodin to low FPS

Wowza Streaming Engine
1

Hello,

I wish to achieve to transcoding from 720p60 to 720p30 for an RTMP stream.

I cannot find the setting to lower the FPS, just bitrate, key frame, audio.

Any suggestions? Please. I already checked the tutorial for transcoder.

Thank you!

Hello there and welcome to the Wowza support forum.

Please take a look at this guide to achieve your desired results:

Eduard, you have to turn on logVideoEncodingParameters.

Then from the output (something like):

INFO server comment – # long: bit_rate_mode: bit rate stuff: 0=H264_CBR, 1=H264_CQT, 2=H264_VBR or 3=H264_TQM

You can then use this information to create a <Parameter> block to add to the container to change the entropy method being used:

<Parameter>
<Name>mainconcept.bit_rate_mode</Name>
<Value>0</Value>
<Type>Long</Type>
</Parameter>

Hello Salvadore,

Thank you very much for the assistance. Works out almost perfect.

Any way to apply CBR on the transcode ?

Thanks,

I’m sorry, I am new to the wowza systems.

Could you please give me more details ?

In the transcoding profile I added the logVideoEncodingParameters, then added the you mentioned, but no result.
