Macros | |
| #define | FF_CODEC_CAP_INIT_THREADSAFE (1 << 0) |
| The codec does not modify any global variables in the init function, allowing to call the init function without locking any global mutexes. More... | |
| #define | FF_CODEC_CAP_INIT_CLEANUP (1 << 1) |
| The codec allows calling the close function for deallocation even if the init function returned a failure. More... | |
| #define | FF_CODEC_CAP_SETS_PKT_DTS (1 << 2) |
| Decoders marked with FF_CODEC_CAP_SETS_PKT_DTS want to set AVFrame.pkt_dts manually. More... | |
| #define | FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM (1 << 3) |
| The decoder extracts and fills its parameters even if the frame is skipped due to the skip_frame setting. More... | |
| #define | FF_CODEC_CAP_EXPORTS_CROPPING (1 << 4) |
| The decoder sets the cropping fields in the output frames manually. More... | |
| #define | FF_CODEC_CAP_SLICE_THREAD_HAS_MF (1 << 5) |

| #define FF_CODEC_CAP_INIT_THREADSAFE (1 << 0) |
The codec does not modify any global variables in the init function, allowing to call the init function without locking any global mutexes.
Definition at line 31 of file codec_internal.h.
| #define FF_CODEC_CAP_INIT_CLEANUP (1 << 1) |
The codec allows calling the close function for deallocation even if the init function returned a failure.
Without this capability flag, a codec does such cleanup internally when returning failures from the init function and does not expect the close function to be called at all.
Definition at line 39 of file codec_internal.h.
| #define FF_CODEC_CAP_SETS_PKT_DTS (1 << 2) |
Decoders marked with FF_CODEC_CAP_SETS_PKT_DTS want to set AVFrame.pkt_dts manually.
If the flag is set, decode.c won't overwrite this field. If it's unset, decode.c tries to guess the pkt_dts field from the input AVPacket.
Definition at line 46 of file codec_internal.h.
| #define FF_CODEC_CAP_SKIP_FRAME_FILL_PARAM (1 << 3) |
The decoder extracts and fills its parameters even if the frame is skipped due to the skip_frame setting.
Definition at line 51 of file codec_internal.h.
| #define FF_CODEC_CAP_EXPORTS_CROPPING (1 << 4) |
The decoder sets the cropping fields in the output frames manually.
If this cap is set, the generic code will initialize output frame dimensions to coded rather than display values.
Definition at line 57 of file codec_internal.h.
| #define FF_CODEC_CAP_SLICE_THREAD_HAS_MF (1 << 5) |
Codec initializes slice-based threading with a main function.
Definition at line 61 of file codec_internal.h.
| #define FF_CODEC_CAP_ALLOCATE_PROGRESS (1 << 6) |
Definition at line 66 of file codec_internal.h.
| #define FF_CODEC_CAP_AUTO_THREADS (1 << 7) |
Codec handles avctx->thread_count == 0 (auto) internally.
Definition at line 70 of file codec_internal.h.
| #define FF_CODEC_CAP_SETS_FRAME_PROPS (1 << 8) |
Codec handles output frame properties internally instead of letting the internal logic derive them from AVCodecInternal.last_pkt_props.
Definition at line 75 of file codec_internal.h.
| #define FF_CODEC_TAGS_END -1 |
FFCodec.codec_tags termination value.
