Re: [FFmpeg-user] feature request/suggestion: add support for dolby vision decoding :)

Maybe it can be made as a FFmpeg Google Summer of Code 2017 mentored project. But now I can see how much time and money it would need to develop something that big. A dual layer decoder and HDR dynamic metadata support has never been implemented in FFmpeg before. We would need to implement the

[FFmpeg-user] Fix interrupted HLS dump

Hi, I've downloaded an HLS live stream with `ffmpeg -i http://example.com/playlist.m3u8 -c copy -bsf:a aac_adtstoasc dump.mp4`. This has worked for me before. I've been keeping the command running overnight and today my SSD was full. I thought, no problem, just cut the file, but the file is

[FFmpeg-user] How to publish new MetaData while transcoding for a RTMP stream?

Hello, I’m using FFmpeg as a transcoder to do some conversion on an incoming RTMP stream (served on my own server with nginx-rtmp-module), and then publish the result to another RTMP service. My publishing client is written in ActionScript 3. In a graph it’s like: Client app |
