Hi,
I was trying to encode a raw yuv file using omx_mpeg4enc. I used the Bellagio omx component based on ffmpeg.
I tried the below pipeline to encode a qcif stream.
gst-launch-0.10 filesrc location= akiyo_qcif.yuv ! omx_mpeg4enc ! filesink location=testoutput.mpeg4
I am able to get an encoded stream but the output resolution and output color format was incorrect.
Then I tried a different pipeline
gst-launch-0.10 filesrc location= akiyo_qcif.yuv ! "video/x-raw-yuv, height=144, width=176, framerate=(fraction)30/1, format=(fourcc)I420" ! omx_mpeg4enc ! filesink location=testoutput.mpeg4
Then gstreamer was not able to encode the stream, saying
"timebase not supported by mpeg4 standard"
So please help me by suggesting a working pipeline for mpeg4 encode using omx_mpeg4enc gstreamer element.
Thanks,
Arun
