Hi all, On embedded device, DSP is used widely, many DSPs have different features, for example: 1. decoder DSP is just a hardware decoder 2. decoder + sink DSP is a decoder plus sink, it can directly accept encoded data, and then decode it and render pcm data into audio device directly. 3. A/V sync DSP can do A/V sync internally or not. There may be more features i don't list. For these features, how can we implement them by gstreamer? For case 1, I think it is esay to do by gstreamer, but for each 2 and 3, it seems gstreamer has no available resources to define these application. So I think we can discuss these topics and find a good solution. BTW, I find a project in gst - "gst-openmax", it is using openmax as low level implementation, but it also has some limitation, for example, no solution for case 2, and we must have openmax implementation for special DSP firstly. I hope we can have top level solution for DSP in despite of the low level implementation, just link gstbasesink virtual class, but all interfaces or virtual functions are defined to handle all the use cases.
