[gst-devel] Increase Performance of Transcoding Pipeline

[Gruenke, Matt]

Well, it depends on several things, but the encode is generally more
expensive than decode.  Therefore, I'd move the queue closer to
ffenc_h263 (or add another queue there, if you've got more than 2
hardware threads).

 

If you don't need the generality of the decodebin, you could try
hand-building that part of the pipeline.  Certain decoders might be
faster than others.

 

I've never used it, but you might find the 'cpureport' element helpful
in determining how much time is spent in the various segments of your
pipeline.

Subject: [gst-devel] Increase Performance of Transcoding Pipeline

 

Hi All,

Are there elements that can help to increase the performance of pipeline
if i would insert them into the pipeline.
Actually, i am using gstreamer to transcode video file from one format
to another format. What i found that this process is taking lot of CPU.
Now i want to optimize the pipeline to make it eats less CPU. I am using
following pipeline to transcode data:

filesrc -> decodebin2 -> queue -> ffmpegcolorspace -> videoscale ->
capsfilter -> ffenc_h263 -> filesink

Any help/pointer/ will be appreciated. Can any one also share which
element is eating lot of CPU in above given pipeline?

Thanks in Advance
