LINUX FFMPEG DVB EXAMPLES DRIVER

Note that this particular encoder was chosen because it is the easiest This fake stream contains some hardcoded content.įor now, we have a single, audio-only channel containing a single MPEGĮlementary Stream, which in turn contains a SMPTE 302m encoded sine-wave. Code reponsible for encoding a valid MPEG Transport Stream, which is then Takes parameters at initialization that will dictate how the simulation A fake bridge driver, which is the module responsible for modprobing theįake tuner and demod modules and implementing the demux logic. On the signal depending on the CNR levels. Returned by the tuner, simulating a device that can lose/reacquire a lock A fake demod driver, which will constantly poll the fake signal quality A fake tuner driver, which will report a bad signal quality if the chosenįrequency is too far away from a table of valid frequencies for a It also validates the existing media DVBĪPIs, thus helping userspace application writers.

Vidtv is a virtual DVB driver that aims to serve as a reference for driver PCM audio stream is decoded by ffmpeg, but no audio is heard yet. Driver generates NULL packets for padding

Driver generates PSI information (PAT, PMT, SDT) Push debug information to userspace via debugfs Push fake audio/video to userspace for testing Help userspace application writers in general Serve as template for new DVB driver writers Subsystem and to kernel development in general. Virtual DVB driver for the Linux media subsystem. media: vidtv: Implement a virtual DVB driver
