#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.

Decoders marked with FF_CODEC_CAP_SETS_PKT_DTS want to set AVFrame.pkt_dts manually.
If the flag is set, utils.c won't overwrite this field. If it's unset, utils.c tries to guess the pkt_dts field from the input AVPacket.

) |
Check AVPacket size and/or allocate data.
Encoders supporting AVCodec.encode2() can use this as a convenience to ensure the output packet data is large enough, whether provided by the user or allocated in this function.
avctx | the AVCodecContext of the encoder |
avpkt | the AVPacket If avpkt->data is already set, avpkt->size is checked to ensure it is large enough. If avpkt->data is NULL, a new buffer is allocated. avpkt->size is set to the specified size. All other AVPacket fields will be reset with av_init_packet(). |
size | the minimum required packet size |
min_size | This is a hint to the allocation algorithm, which indicates to what minimal size the caller might later shrink the packet to. Encoders often allocate packets which are larger than the amount of data that is written into them as the exact amount is not known at the time of allocation. min_size represents the size a packet might be shrunk to by the caller. Can be set to 0. setting this roughly correctly allows the allocation code to choose between several allocation strategies to improve speed slightly. |
