Function Documentation

◆ ff_hwaccel_uninit()

void ff_hwaccel_uninit ( AVCodecContext avctx)
name
it s the only field you need to keep assuming you have a context There is some magic you don t need to care about around this just let it vf default minimum maximum flags name is the option name
Definition: writing_filters.txt:88
AV_HWDEVICE_TYPE_NONE
@ AV_HWDEVICE_TYPE_NONE
Definition: hwcontext.h:28
AV_CODEC_HW_CONFIG_METHOD_AD_HOC
@ AV_CODEC_HW_CONFIG_METHOD_AD_HOC
The codec supports this format by some ad-hoc method.
Definition: codec.h:338
frames
if it could not because there are no more frames
Definition: filter_design.txt:266
format
Filter the word “frame” indicates either a video frame or a group of audio as stored in an AVFrame structure Format for each input and each output the list of supported formats For video that means pixel format For audio that means channel sample format(the sample packing is implied by the sample format) and sample rate. The lists are not just lists
