#6389(avformat:new): Support H.265 over Adobe HTTP-FLV or RTMP

#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

For example: {{{ Content-Type: audio/L16;rate=44100;channels=2 }}} This error is from pcmdec.c as it cannot find the "rate" parameter to parse. That's because it is passed the mime-type without its parameters in http.c, a change that happened in this commit from 8 months ago: https://github.com/FFmpeg/FFmpeg/commit/0cd2e7dcfbc835f4519f1b2b7da6bd902db… It can be fixed in two ways: - revert that commit and let components making used of "mime-type" handle it properly if it has parameters (so according to this commit's description, modify the HLS component to handle the eventual mime-type params) - add an exception for audio/l16: {{{ if (av_strncasecmp(p, "audio/l16", 9) == 0) { s->mime_type = av_strdup(p); } else { s->mime_type = av_get_token((const char **)&p, ";"); } }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/10869> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#10125: ffmpeg-3.4.12 does not build (i686-w64-mingw32) ---------------------------------------+---------------------------------- Reporter: Carlo Bramini | Type: defect Status: new | Priority: normal Component: build system | Version: 3.4.12 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------------+---------------------------------- I tried to build ffmpeg-3.4.12, which is the last one supporting Windows XP, but it fails to compile the resource file for Windows. Running verbose build, it prints this output on the console: {{{ $ make V=1 i686-w64-mingw32-windres -I. -Isrc/ --preprocessor "i686-w64-mingw32-gcc -E -xc-header -DRC_INVOKED -MMD -MF libavdevice/avdeviceres.d -MT libavdevice/avdeviceres.o" -o libavdevice/avdeviceres.o /home/carlo/packages/ffmpeg/mingw64-i686-ffmpeg-3.4.12-1.noarch/src/ffmpeg-3.4.12/libavdevice/avdeviceres.rc /bin/sh: i686-w64-mingw32-gcc -E -xc-header -DRC_INVOKED -MMD -MF libavdevice/avdeviceres.d -MT libavdevice/avdeviceres.o: No such file or directory make: *** [/home/carlo/packages/ffmpeg/mingw64-i686-ffmpeg-3.4.12-1.noarch/src/ffmpeg-3.4.12/ffbuild/common.mak:86: libavdevice/avdeviceres.o] Error 1 }}} I found a solution by comparing ffbuild/common.mak between this version and the latest 5.1.2, which has already fixed this bug. According to this reply that I received on the mailing list: http://ffmpeg.org/pipermail/ffmpeg-devel/2022-December/305046.html a patch already exists in commit f9626d1065c43f1d51afe66bdf988b9f33729440. Is it possible to apply this patch also to 3.4 branch, to allow building this version on Windows, when an updated release will be made public? Thank you very much. Sincerely. -- Ticket URL: <https://trac.ffmpeg.org/ticket/10125> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
