The OMX specs states that the nBufferCountActual of a port has to default to its nBufferCountMin. If we don't change nBufferCountActual we purely rely on this default. But in some cases, OMX may change nBufferCountMin before we allocate buffers. Like for example when configuring the input ports with the actual format, it may decrease the number of minimal buffers required. This method checks this and update nBufferCountActual if needed so we'll use less buffers than the worst case in such scenarios. SetParameter() needs to be called when the port is either disabled or the component in the Loaded state. Don't do this for the decoder output as gst_omx_video_dec_allocate_output_buffers() already check nBufferCountMin when computing the number of output buffers. On some platform, like rpi, the default nBufferCountActual is much higher than nBufferCountMin so only enable this using a specific gst-omx hack. https://bugzilla.gnome.org/show_bug.cgi?id=791211 |
