As we all know, the FLV specification does not support H.265, and the major browsers have gradually not support flash in recent years, and Adobe has announced that Flash will no longer support Flash at the end of 2020. As the owner of FLV-related technologies, Adobe estimates that there is no power to update the specification to support H.265; the authorization plan of some patent owners of H.265 standards is accused of grab the money, and the enthusiasm of many software vendors is.
Not long after the H.265 standard, someone request Adobe to join the H.265 support in the FLV specification:
Https://community.adobe.com/t5/flash-player/h265-support/td-p/5657976
Https://tracker.adobe.com/#/view/fp-3650828
But unfortunately, Adobe has not updated the FLV specification. The Ffmpeg community has also mentioned that if Adobe does not update the specification, then they will not support H.265 in the FLV.
Is there any difficulty in supporting H.265 in FLV? The answer is almost no difficulty, as long as a new encoding ID indicates that H.265 is OK. FFMPEG patches that support packaging / unpacking H.265 have been supported, more common, no longer listed, compare unified encoded IDs 12. The problem of encapsulation (incentives) / universal (play) is solved, and the server needs to be modified. In addition to adding an encoded ID, it is also necessary to extract a new structure VPS (Video Parameter Set) in H.265 video encoding. After playing the request, the content of this structure is sent to the player.
There have been many FLV open source schemes that support H.265 video encoding, basically run, but the resolution of the VPS structure is relatively rough. Some time ago joined the support of H.265 on the basis of nginx-http-flv-module, there is no problem with the test, the test environment is as follows:
OS: Debian GNU / Linux 7.8
Publisher: Latest version of FFMPEG + supports H.265 video encoded FLV patch
Player: The open source player IjkPlayer, supports H.265 video encoding (unsuppracted)
Server: nginx-http-flv-module + supports H.265 video encoded FLV patch
The screenshot of the test is as follows:
Streamlift
Open playback
Streaming Details 1
Streaming Details 2
Note that this part of the code has no open source, and the IJKPlayer Demo native does not support the input network URL, and some code is required.
Today, some netizens asked me whether the code has been modified to support HTTP-FLV mode to play H.265 video, and have not been tested. I just added a "INABLE-FFPLAY option to configure, compiled FFPLAY, and the test screenshot is compiled, the test screenshot is shown below:
HTTP-FLV mode supports H.265 encoded video

Because I have a lot of netizens, I reiterated it, this part of the code is not open source, I also mentioned above, there are many ways to support H.265 online, but the resolution VPS is very rough, so Details of the stream in STAT. In addition, the latest HLS specification requires that if the video encoding is H.265, the package format must be FMP4, so many of the online HLS support HLS is useless.
However, if important functions are contributed to nginx-http-flv-module or repair significant bugs, I will give it for free. The reason for this is that nginx-http-flv-module is more than 3 years. The community participation is not high. Most of the work is a person's obligation to maintain (of course thanks to many netizens test, BUG feedback and PR) There are also some company integration projects to declare independent research and development. The BSD-2 agreement is already very loose, allowing commercial, but at least keep my license.
Finally, if you have any questions, please look at the readme or readme.cn of nginx-http-flv-module, the former is English, the latter is Chinese. I have a question before I asked a question. I thought I had already written on ReadMe, I will answer the readme. I will not answer. As a result, the netizens said that my attitude is not good, and a lot of things should be packaged with a lot of nonsense. Please, my time is also the time. When I have more time, I have to face you alone, you have not given me money, I am not obligated to give you a variety of questions.
