#6389: Support H.265 over Adobe HTTP-FLV or RTMP ----------------------------------+--------------------------------------- Reporter: winlin | Type: task Status: new | Priority: normal Component: avformat | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- FFMPEG is a great project, thank everyone's awesome work! Adobe HTTP-FLV or RTMP is the defacto protocol for live streaming over internet and almost all encoders support pushing stream to server or CDN over RTMP protocol, while player like Adobe Flash or Android ExoPlayer or FFMPEG also support HTTP-FLV. Although H.265 is supported by HLS and TS, we can also delivery H.265 over HTTP-TS for realtime live streaming service, but CDNs are more friendly to RTMP/HTTP-FLV. For example, all, that's all, not some, all live streaming service in China now are using RTMP/HTTP-FLV for 3-5s latency, none of them chooses HLS for its large latency. Maybe realtime live streaming is not popular in the US, but I think it's only because the CDN is not very good at delivery RTMP/HTTP-FLV. I know some friends in the UK and US are now build the realtime CDN themselves, some use [NGINX-RTMP](https://github.com/arut/nginx-rtmp-module) like facebook, others using [SRS](https://github.com/ossrs/srs) to delivery realtime live streaming: {{{ Encoder ====RTMP====> SRS(Cluster) ====RTMP/HTTP-FLV====> Player }}} Now, it work very good for H.264+AAC over RTMP/HTTP-FLV for 3-5s realtime live streaming service, what about H.265? Is there any plan to support H.265 over HTTP-FLV/RTMP? -- Ticket URL: <https://trac.ffmpeg.org/ticket/6389> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4888(avcodec:new): 62bd8deef causes a regression in HEVC decoding

#4888: 62bd8deef causes a regression in HEVC decoding ----------------------------------+-------------------------------------- Reporter: staalebk | Type: defect Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- Summary of the bug: I'm trying to extract a thumb from the middle of a live TS, containing one HEVC-stream. Before this patch I would always get a good looking thumb, but with this patch I would for the most part get a mostly gray frame. If I generates a few more thumbnails i see that it eventually spits out the same frame that ffmpeg before this patch produced as the first thumb, and it looks OK. However it is much more blocky than what the previous ffmpeg produced.

#9412: HEVC fails to seek on keyframe -----------------------------------+-------------------------------------- Reporter: SuRGeoNix | Type: defect Status: new | Priority: important Component: avformat | Version: git-master Keywords: hevc seek | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -----------------------------------+-------------------------------------- I'm using av_seek_frame and even if it returns 0 pb will not be at an actual keyframe. The issues seems to happen with any HEVC/mpeg-ts format container.
