* avcodec/flacenc: Mark encoder as init-threadsafeAndreas Rheinhardt2021-05-02
| | | | Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec: Remove redundant freeing of extradata of encodersAndreas Rheinhardt2021-04-28
| | | | | | | | AVCodecContext.extradata is freed generically by libavcodec for encoders, so it is unnecessary for an encoder to do it on its own. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* | avcodec/flacenc: Fix Invalid Rice orderGeorge Boyle2015-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | Fixes ticket #4628. The problem arose, in the sample file at least, in the last block where the minimum and maximum Rice partition orders were both 0. In that case, and any other where pmax == pmin, the original UINT32_MAX placeholder value for bits[opt_porder] was getting overwritten before the comparison to check if the current partition order is a new optimal, so the correct partition order and RiceContext params were not being set.
