Hi, I'm a gstreamer user and recently starting using gstreamer1-libav. I
notice that some gst-libav codec have the “max-thread” option, which allow
frames to be processed in multiple threads, while others don't. And this is
decided by whether the underlying libav codec have cap
"AV_CODEC_CAP_FRAME_THREADS". So I'm wondering why some codec for
picture processing (which means frames are not related) doesn't have that cap.
i.e. the codec mjpegdec doesn't have the cap, while the openjpeg/pngdec do
have. Is it not possible to decode mjpeg image in parallel or it's just not
implemented yet.
My use case is decoding a jpeg stream on a multi-core system, and it
use only one core. I'm using libav 2.8.8, and I see no change to this cap in
git master code.
