Get the HEVC codec for free You may have hardware that supports this High-Efficiency Video Coding, also known as HEVC or H.265, is one common media codec that is not free to use in commercial products. However, aspointed out by Froggypwns on Reddit, many graphics cards ship with a lic...
.close = hevc_decode_free, .decode = hevc_decode_frame, .flush = hevc_decode_flush, .update_thread_context = hevc_update_thread_context, .init_thread_copy = hevc_init_thread_copy, .capabilities = CODEC_CAP_DR1 | CODEC_CAP_DELAY | CODEC_CAP_SLICE_THREADS | CODEC_CAP_FRAME_THREADS, ....
The MainConcept HEVC SDK, used today by many top companies in the industry to power their software offerings, delivers on the promise of higher performance with up to 30% greater bitrate efficiency than open source and it continually ranks at the top for overall codec quality. The latest ...
CODEC_CAP_SLICE_THREADS | CODEC_CAP_FRAME_THREADS, .profiles = NULL_IF_CONFIG_SMALL(profiles), }; 从源码能够看出。HEVC解码器初始化函数是hevc_decode_init()。解码函数是hevc_decode_frame(),关闭函数是hevc_decode_free()。 hevc_decode_init() hevc_decode_init()用于初始化HEVC解码器。 该函数的定...

ff_hevc_parser是HEVC解析器相应的AVCodecParser结构体。该结构体的定义位于libavcodec\hevc_parser.c。例如以下所看到的。 AVCodecParser ff_hevc_parser = { .codec_ids = { AV_CODEC_ID_HEVC }, .priv_data_size = sizeof(HEVCParseContext),
Oddly, before I did that, I tried VLC (which supposedly contains an H265 codec). But, the Windows Video Troubleshooter still complained there was no HEVC codec and a sample video I tried came up with a black screen. With the free Microsoft version, that same video works fine. ...
The current HEVC codec is a paid for App… There was (and still is) a second identical version that was free. Those of us who installed it while still available can still get updates, and can even install it on our new devices as it's listed as an 'owned app' when we sign in ...
