* Revert "media: dvb: Use fill count for dvb_ringbuffer"Gilad Broner2014-06-221-1/+4
| | | | | | | | | | | | | This reverts commit f3ba3f6a042102f9e834b2bee89796f0a0efd20e. In order to sync on buffer state with SDMX, demux manipulates the read/write pointers of dvb_ringbuffer directly to account for new data from SDMX. When dvb_ringbuffer is using fill count internally, updating the read/write pointers does not affect the fill count and so buffer is out of sync with SDMX.

* media: dvb: Add buffer flushing APIGilad Broner2014-02-051-0/+4
| | | | | | | | | | | | Automatically flushing the output buffer when buffer overflows is not always the desired behavior as this discards pending data while user may actually want to read the data collected so far. Add a new module parameter to allow turning off the automatic buffer flushing as well as a new ioctl DMX_FLUSH_BUFFER to allow user to flush the output buffer manually.

* media: dvb: Use fill count for dvb_ringbufferGilad Broner2014-01-121-5/+2
| | | | | | | | | | | | | For circular buffer, to distinguish between a full buffer and an empty buffer, dvb_ringbuffer implementation reserved one slot to always be unused (so read and write offset can only be equal when buffer is empty). This is not suitable for working with circular buffers managed by hardware like TSPP2, as it causes the HW offsets and dvb_ringbuffer offset to be out-of-sync.

The plugin utilizes the HW capabilities of TSPPv2 to offload some processing such as: TS packet inspection, PID filtering, PES assembly, Indexing and more.

* media: dvb: Add detection of SEI messagesHamad Kadmany2013-09-041-0/+2
| | | | | | | | | | | | Video decoder expects SEI messages to be sent along with the data of the following frame instead of the preceding frame. Detection of SEI messages allows closure of previous frame data when SEI messages are encountered.

| | | | | | | | | | demux kernel implementation exposed capabilities both to user-space applications and internally to demux-device layer. demux-device layer was changed to re-use the capabilities reported to user-space to avoid duplications and redefinitions of capabilities.

* media: dvb: Move video pattern search to dvb-demux levelHamad Kadmany2013-09-041-18/+32
| | | | | | | | | | | | | | | | Video pattern search is required for both video framing done at plug-in level and indexing to be done by dvb-demux level. The pattern search routine was moved as a common service at dvb-demux level so that it can be used by both. At plug-in level, the plug-in needs the video codec in order to perform the framing regardless of the indexing parameters, therefore indexing parameters was renamed to video codec.

* media: dvb: Out-of-Band (OOB) commands supportGilad Broner2013-09-041-3/+30
| | | | | | | | | | | | | | | Extend demux API with ability to push OOB commands to the DVR device during playback from memory. OOB command is then received by all running filters. Two types of OOB commands are supported: 1. Data markers - these allow user to mark with an identifier certain points in the source stream, and be notified via the demux filters when those are reached. 2. End-of-Stream (EOS) - allow user to declare source stream has reached its end. This will make pending data readable to user and block any more data from being output.

* media: dvb: mpq: Secure demux supportHamad Kadmany2013-09-041-2/+17
| | | | | | | | | | | | | | | This change adds support for demuxing of encrypted streams which current software demux implementation does not support. User-space API is extended to allow setting of key ladder information needed in order to perform decryption. If secure demux application is available, demuxing does not take place in the dvb demux sw filter anymore but instead is performed in the new secure demux, regardless of whether the stream is encrypted or not. Otherwise, the dvb demux sw filter will be used as before and demuxing of encrypted streams will not be available.

* media: dvb: mpq: Support new elementary stream data eventsLiron Kuch2013-09-041-6/+61
| | | | | | | | | | | | Video elemenatry stream data is usually passed from demux to a video consumer (e.g. video decoder) in kernel-space via tunneling. However there are cases when the video consumer is a user-space application controlled by the middleware. This change adds support for notifying user-space about newly available elementary stream data and associated meta-data, using the existing events queue mechanism.

* [media] demux.h: Remove duplicated enumMauro Carvalho Chehab2013-04-081-1/+1
| | | | | | | | | | | | "enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the same enum declared twice, since Kernel (2.6.12). There's no reason to duplicate it there, and sparse complains about that: drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types So, remove the internal define, keeping just the external one. Internally, use only "enum dmx_ts_pes", as it is too late to drop dmx_pes_type_t from the userspace API. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* [media] dvb: Add DVBv5 statistics propertiesMauro Carvalho Chehab2013-01-232-2/+79
| | | | | | | | | | | | | | | | | | The DVBv3 statistics parameters are limited on several ways: - It doesn't provide any way to indicate the used measure, so userspace need to guess how to calculate/use it; - Only a limited set of stats are supported; - Can't be called in a way to require them to be filled all at once (atomic reads from the hardware), with may cause troubles on interpreting them on userspace; - On some OFDM delivery systems, the carriers can be independently modulated, having different properties. Currently, there's no way to report per-layer stats. To address the above issues, adding a new DVBv5-based stats API. While here, correct inner code nomenclature on a few places.
