Macros | |
| #define | AV_CODEC_CAP_DRAW_HORIZ_BAND (1 << 0) |
| Decoder can use draw_horiz_band callback. More... | |
| #define | AV_CODEC_CAP_DR1 (1 << 1) |
| Codec uses get_buffer() or get_encode_buffer() for allocating buffers and supports custom allocators. More... | |
| #define | AV_CODEC_CAP_DELAY (1 << 5) |
| Encoder or decoder requires flushing with NULL input at the end in order to give the complete and correct output. More... | |
| #define | AV_CODEC_CAP_SMALL_LAST_FRAME (1 << 6) |
| Codec can be fed a final frame with a smaller size. More... | |
| #define | AV_CODEC_CAP_EXPERIMENTAL (1 << 9) |
| Codec is experimental and is thus avoided in favor of non experimental encoders. More... | |
| #define | AV_CODEC_CAP_CHANNEL_CONF (1 << 10) |
| Codec should fill in channel configuration and samplerate instead of container. More... | |
| #define | AV_CODEC_CAP_FRAME_THREADS (1 << 12) |
| Codec supports frame-level multithreading. More... | |
| #define | AV_CODEC_CAP_SLICE_THREADS (1 << 13) |
| Codec supports slice-based (or partition-based) multithreading. More... | |
| #define | AV_CODEC_CAP_PARAM_CHANGE (1 << 14) |
| Codec supports changed parameters at any point. More... | |
| #define | AV_CODEC_CAP_OTHER_THREADS (1 << 15) |
| Codec supports multithreading through a method other than slice- or frame-level multithreading. More... | |
| #define | AV_CODEC_CAP_VARIABLE_FRAME_SIZE (1 << 16) |
| Audio encoder supports receiving a different number of samples in each call. More... | |
| #define | AV_CODEC_CAP_AVOID_PROBING (1 << 17) |
| Decoder is not a preferred choice for probing. More... | |
| #define | AV_CODEC_CAP_HARDWARE (1 << 18) |
| Codec is backed by a hardware implementation. More... | |
| #define | AV_CODEC_CAP_HYBRID (1 << 19) |
| Codec is potentially backed by a hardware implementation, but not necessarily. More... | |
| #define | AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE (1 << 20) |
| This encoder can reorder user opaque values from input AVFrames and return them with corresponding output packets. More... | |
| #define | AV_CODEC_CAP_ENCODER_FLUSH (1 << 21) |
| This encoder can be flushed using avcodec_flush_buffers(). More... | |
| #define | AV_CODEC_CAP_ENCODER_RECON_FRAME (1 << 22) |
| The encoder is able to output reconstructed frame data, i.e. More... | |
