| | | | | Now generating the extension in place once all the data is already in the right place.
* DRED versioning in bitstreamJean-Marc Valin2023-04-142-5/+18
| | | | | | Adding a 'D' byte to signal the DRED experiment, along with a version number byte. This entire commit will be reverted once DRED is finalized and given a non-experimental extension number.

* Adds OPUS_SET_INBAND_FEC(2) optionJean-Marc Valin2022-06-301-5/+8
| | | | | Unlike OPUS_SET_INBAND_FEC(1), the encoder does not necessarily switch to SILK if we have music.
* Fix 8101b33 to decode ignored redundancyMark Harris2022-06-261-5/+9
| | | | | | | Even if the redundancy is ignored, the final range from the decoder is needed for testing. Reviewed by Timothy B. Terriberry.
* Correct redundancy handling with lost/DTX framesMark Harris2022-06-251-2/+7
| | | | | | | | | | | | | | | | | In https://github.com/xiph/opus/issues/253, the encoder generates a Hybrid frame with redundancy, to switch to CELT-only mode, and then activates DTX immediately afterwards. The decoder ran Hybrid PLC, which isn't right. Use CELT PLC instead if there was already a transition to CELT via redundancy at the end of the previous frame. Also do not use a stale CELT decoder to decode a second redundancy frame when the first redundancy frame for a transition from SILK-only mode was lost. Instead of mixing in old audio from the last time that CELT was used, ignore the second redundancy frame in this case. Alternatively the CELT decoder could be reset before decoding, but it would not be ready until after the 2.5 ms of audio that is needed. Reviewed by Jean-Marc Valin.

* repacketizer_demo: check for read errors to fix compiler warningsNirbheek Chauhan2020-08-211-7/+37
| | | | | | | | | | | Actually check for read errors instead of just storing the return value in a variable that then never gets checked. Also fixes "conversion from 'size_t' to 'int', possible loss of data" compiler warnings on Windows with MSVC caused by storing the size_t returned by fread() into an int variable.
