#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. How to reproduce (b7baebb75 is the commit just before the patch): {{{ % ./ffmpeg.b7baebb75 -an -i hevc_fail.ts -vframes 1 before_patch%d.jpg ffmpeg version N-74781-gb7baebb Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.7 (Debian 4.7.2-5) configuration: libavutil 54. 31.100 / 54. 31.100 libavcodec 56. 60.100 / 56. 60.100 libavformat 56. 40.101 / 56. 40.101 libavdevice 56. 4.100 / 56. 4.100 libavfilter 5. 40.101 / 5. 40.101 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 2.101 / 1. 2.101 [NULL @ 0x1f74780] PPS id out of range: 0 [hevc @ 0x1f74780] PPS id out of range: 0 [hevc @ 0x1f74780] Error parsing NAL unit #2.

#4954(avformat:new): joint stereo indicator missing from mp3 headers

#4954: joint stereo indicator missing from mp3 headers -------------------------------------+------------------------------------- Reporter: pico4743 | Type: defect Status: new | Priority: normal Component: avformat | Version: git- Keywords: mp3 | master joint_stereo header | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: mp3 header files created by ffmpeg do not specify a channel mode of joint_stereo when joint_stereo is performed by libmp3lame. Details: libmp3lame provides a switch (-joint_stereo) to select either joint_stereo or plain stereo. The interface to lame works correctly so that the audio frames are fine, but ffmpeg doesn't use the lame library to write the mp3 header. Instead libavformat/mp3enc.c sets the channel mode to either MONO or STEREO based on how many channels there are. {{{ switch (codec->channels) { case 1: channels = MPA_MONO; break; case 2: channels = MPA_STEREO; break; default: av_log(s, AV_LOG_WARNING, "Unsupported number of channels, " "not writing Xing header.\n"); return -1; } ... header |= channels << 6; }}} MPA_JSTEREO should be used when appropriate. The repair doesn't seem simple, but I'd be willing to help if someone wants to discuss approaches. How to reproduce: {{{ use a version with libmp3lame enabled % ffmpeg -i input.mp3 -joint_stereo 1 output.mp3 The relevant bits of the output.mp3 header will be 0 == MPA_STEREO ffmpeg version -- git master fb4d350 }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/4954> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
