From: Philipp Zabel Date: Thu, 27 Jun 2013 09:59:01 +0000 (-0300) Subject: [media] coda: add CODA7541 decoding support X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=918c66fd41268ec34bba0a82f4221ddc18e9501b;p=openwrt%2Fstaging%2Fblogic.git [media] coda: add CODA7541 decoding support This patch enables decoding of h.264 and mpeg4 streams on CODA7541. Queued output buffers are immediately copied into the bitstream ringbuffer. A device_run can be scheduled whenever there is either enough compressed bitstream data, or the CODA is in stream end mode. Each successful device_run, data is read from the bitstream ringbuffer and a frame is decoded into a free internal framebuffer. Depending on reordering, a possibly previously decoded frame is marked as display frame, and at the same time the display frame from the previous run is copied out into a capture buffer by the rotator hardware. The dequeued capture buffers are counted to send the EOS signal to userspace with the last frame. When userspace sends the decoder stop command or enqueues an empty output buffer, the stream end flag is set to allow decoding the remaining frames in the bitstream ringbuffer. The enum_fmt/try_fmt functions return fixed capture buffer sizes while the output queue is streaming, to allow better autonegotiation in userspace. A per-context buffer mutex is used to lock the picture run against buffer dequeueing: if a job gets queued, then streamoff dequeues the last buffer, and then device_run is called, bail out. For that the interrupt handler has to be threaded.
