[vlc-devel] [RFC PATCH 0/8] Notify the decoder state

[Thomas Guillem]

This set of patches adds a way to notify the input_thread and libvlc that a
decoder thread encountered an error.

The state enum is called decoder_state. For now, it has only 2 possibles
values: ERROR_OUTPUT and ERROR_GENERIC. I don't know if it's useful to
broadcast a future non-error decoder state, or to differentiate the error that
way.

When the input_thread receive an error from a decoder, it will stop the
corresponding es_out. This will release the output and destroy the decoder. I
think it's a good improvement, you won't have a thread that does nothing in
case of error anymore.

The decoder state is also forwarded to the libvlc with enough informations to
handle it: The faulty module name, the id and category of the track, and the
type of error.

Thomas Guillem (8):
  decoder: don't notify record decoders
  decoder: store the es_id
  input: add INPUT_CONTROL_DECODER_STATE control
  decoder: notify the input_thread in case of error
  input: deactivate the decoder ES track in case of error
  events: remove unused input thread events
  input: broadcast vlc_InputDecoderStateChanged event
  libvlc: add libvlc_MediaPlayerDecoderStateChanged event
