Dont know, what are compiling and how and on which maschine? Assertion failed: (el >= 0), function calc_energy, file psymodel.c, line 576. i have and question about pcm_f32le 2 wav convert or vpxenc if you're talking about the cli just want to encode rawvideo frames to vp9 then you might just want to use libvpx there's nothing else that does as much as the ffmpeg libs can oh, is there another competing one that i would be familiar with maybe? ffmpeg is pretty good, are there competing codecs though? Basically someone who knows the ins and outs to make a streaming platform By any chance does anyone know the correct job title for someone experienced in multimedia / rtmp / ott? Is there a better way to pack in that information without losing quality? 420p seems pretty good some players (Quicktime, TVs with media support) just don't support the higher stuff FishPencil: for computer video, yes (or formats with the same sampling, but different memory arrangements, like NV12 or YUYV) Is YUV420p the most widely used color encoding method?

FishPencil: yes (at least the h264 stuff does, I think it's restricted to that by the permitted profiles) Next message (by thread): ffmpeg-devel.log.20180204.Previous message (by thread): ffmpeg-devel.log.20180203.If there is a risk that a recording will get ungracefully terminated, TS is a better format than .20180204 burek burek021 at record to TS file, rather than MP4/MOV in future. There are a few webpages and tools that explain how to reconstruct the MOOV atom from a known, working file of exactly the same template. Most mp4 writing code will generate the moov atom last, and at the end of the file (note that optimizing an MP4 file involves moving this atom to the front of the file),But yeah, your input file into FFmpeg was not complete, therefore MOOV atom not found. In order to fix FFMPEG: Moov atom not found problem, you can check out the below-mentioned troubleshooting guide: the moov atom likely isn't there because the recording was unceremoniously terminated.
