Detailed Description

The input decoder connects the input client pushing data to the decoder implementation (through the matching elementary stream) and the following output for audio, video and subtitles.

It follows the locking rules below:

• The fifo cannot be locked when calling function from the decoder module implementation.
• However, the decoder module implementation might indirectly lock the fifo when calling the owner methods, in particular to send a frame or update the output status.
• The input code can lock the fifo to modify the global state of the input decoder.

Backpressure preventing starvation is done by the pacing of the decoder, the calls into the decoder implementation, and the limits of the fifo queue.

Basically a very fast decoder will often wait since the fifo will be consumed really quickly and thus almost never stay under the lock. Likewise, when the decoder is slower and the fifo can grow, it also means that the decoder thread will wait more often on the decoder_t::pf_decode call, which is done without the fifo lock as per above rules.

In addition with the standard input/output cycle from the decoder, the video decoders can create sub-decoders for the closed captions support embedded in the supplementary information from the codecs.

To do so, they need to create a decoder_cc_desc_t matching with the format that needs to be described (number of channels, type of channels) and they then create them along with the closed-captions content with decoder_QueueCc.

In the input/decoder.c code, the access to the sub-decoders in the cc.pp_decoders table is protected through the cc.lock mutex. Taking this lock ensures that the sub-decoder won't get asynchronously removed while using it, and any mutex from the sub-decoder can then be taken under this lock.

vlc_input_decoder_IsSynchronous()

static bool vlc_input_decoder_IsSynchronous ( const vlc_input_decoder_t *  dec )

inlinestatic

When the input decoder is being used only for packetizing (happen in stream output configuration.), there's no need to spawn a decoder thread.

The input_decoder is then considered synchronous.

Return values

true	When no decoder thread will be spawned.
false	When a decoder thread will be spawned.

Spawns a new decoder thread from the input thread.

Parameters

p_input	the input thread
p_es	the es descriptor

Returns
