mp4 video bitrate setting has no effect #4

Closed XeonG closed 7 years ago

XeonG commented 8 years ago

video bitrate for mp4 encoder has no effect at all on the encoded video's bitrate

tested using the h264 win7 x64

maybe expose more of the h264 encoder settings on the MP4Recorder

win10 x64 with unity 5.5, same issue +1

XeonG commented 7 years ago

isaint seems to have a new dev branch with webm support .. I tried to get it working, didn't get far.. maybe you can try and see if its improved things.

same here. Windowns7 unity5.4.2

videos are created 300-800kbps.

azu1129 commented 7 years ago

I changed below code and got good quality mp4 file :)

param.iRCMode = RC_BITRATE_MODE; to param.iRCMode = RC_QUALITY_MODE; at Plugin/Encoder/fcOpenH264Encoder.cpp LINE:94

but yet bitrate value doesnt work.

azu1129 commented 7 years ago

I think that SEncParamExt inteface is needed to work bitrate value.

setting is like this.

param.iRCMode              = RC_OFF_MODE;
param.iNumRefFrame         = 1;
param.bEnableAdaptiveQuant = false;
param.bEnableFrameSkip                     = true;    // true: need for set bitrate

but SEncParamExt has many parameters and confusing. If anyone knows, please tell me how to set SEncParamExt as SEncParamBase default.

fixed in recent versions.
