Linux/AM5728: H.264 encode file is too big

vefone

Part Number: AM5728

Tool/software: Linux

Hi,

TI, I use the command "gst-launch-1.0 -v videotestsrc ! 'video/x-raw, format=(string)YUY2, width=(int)1920, height=(int)1080' ! vpe ! ducatih264enc level=level-51 profile=high bitrate=6000 ! h264parse ! filesink location=/home/root/1920x1080.264" to test h264 encode for 10 minutes. And I found the size of 1920x1080.264 is too big. the size is 900MiB. If I test it on the NXP platform,the size is 300MiB. Are there some way to decrease the size?

By the way, I test it on SDK03.01 and SDK 04.01.

Hello vefone,

I will check and let you know the results on my side.
Meanwhile you could check the encoder's properties and try with different options.
You could find the encoder user guide here: git.ti.com/.../docs

Hello,

I tried on my side with the pipeline that you are using. I observed for 9:39 mins 681MB.
The file size depends on many enc's params like bitrate, video content that you are encoding etc.
For example with the default bitrate the size is ~460MB for ~14 mins.
As you could check with gst-inspect-1.0 ducatih264enc not all enc's params are exposed as enc's properties in gstreamer.
You could try videnc2test demo and tuning the enc's params(check the enc's user guide in the previous answer).
