Andreas Rheinhardt	8b32a6f1aa	avcodec/dnxhdenc: Mark encoder as init-threadsafe Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	4 years ago
Andreas Rheinhardt	3c1208be02	avcodec/dnxhdenc: Use av_memdup() instead of av_malloc()+memcpy() Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	4 years ago
Andreas Rheinhardt	eb583b3cb9	avcodec/dnxhdenc: Fix segfault when using too many slice threads The DNXHD encoder's context contains an array of 32 pointers to DNXHDEncContexts used in case of slice threading; when trying to use more than 32 threads with slice threading, the encoder's init function errors out, but the close function takes avctx->thread_count at face value and tries to free inexistent elements of the array, leading to potential crashes. Fix this by modifying the check used to decide whether the slice contexts should be freed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	4 years ago
Andreas Rheinhardt	1393c7edae	avcodec/dnxhdenc: Avoid copying packet data, allow user-supplied buffers When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data by using ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	4 years ago
Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs 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.

Andreas Rheinhardt	11bc790893	avcodec: Remove deprecated AVCodecContext.coded_frame Deprecated in `40cf1bbacc`. (The currently disabled filter vf_mcdeint and vf_uspp were users of this field; they have not been changed, so that whoever wants to fix them can see the state of these filters when they were disabled.)

Andreas Rheinhardt	10d059bb24	avcodec/dnxhd: Make ff_dxnhd_get_cid_table return a pointer, not index All callers only use the index into ff_dnxhd_cid_table to get a pointer to the desired entry. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago
