@return descriptor for given codec ID or NULL if no descriptor exists.
@return codec descriptor with the given name or NULL if no such descriptor exists.
Iterate over all codec descriptors known to libavcodec.
Subtitle codec is bitmap based Decoded AVSubtitle data can be read from the AVSubtitleRect->pict field.
Codec uses only intra compression. Video and audio codecs only.
Codec supports lossless compression. Audio and video codecs only.
Codec supports lossy compression. Audio and video codecs only. @note a codec may support both lossy and lossless compression modes
Codec supports frame reordering. That is, the coded order (the order in which the encoded packets are output by the encoders / stored / input to the decoders) may be different from the presentation order of the corresponding frames.
Subtitle codec is text based. Decoded AVSubtitle data can be read from the AVSubtitleRect->ass field.
This struct describes the properties of a single codec described by an AVCodecID. @see avcodec_descriptor_get()
