BTW, I understand from brief searching that the wallclock option is relatively new. Just curious how FFmpeg users dealt with Decklink boards until they were available?? Older generation cards were better, next gen cards like duo2 have more problems timestamp-wise.

I don't use releases myself, but I always advise AV archivists, who implement FFmpeg in their workflow, to use the last release of an actively maintained branch. Why? Because for the people living outside our "gang" it is much easier to keep the software updated this way (e.g. via Brew). Therefore I am really grateful to the volunteers who make this possible, even if I am not a direct beneficiary.

For our production server we tend to like tagged releases, not HEAD or a changeset somewhere in a branch. This being said, since master is ok, I think I'll switch to master/HEAD instead of going to 2.8.8 until 3.2 is released (BTW, great instructions to reproduce, without any external > dependencies or input files. Thanks for that!) > My pleasure. And thank you for the complete answer, it makes tons of sense.

[FFmpeg-user] ES info problem
Hello! I am trying to generate still image with silent audio-track to push it to the DVB network. MPEG-ts stream is generating with this command: ~/bin/ffmpeg -loop 1 -i ~/image-mpeg4.jpg -f lavfi -i anullsrc -map 0:v -map 1:a -c:a mp2 -b:a 128k -c:v libx264 -preset medium -profile:v baseline -level 3.0 -tune stillimage -pix_fmt yuv420p -s 720x576 -framerate 25 -crf 1 -bufsize 2000k -maxrate 2000k -f mpegts udp://239.31.5.205:1234 in the result I get correct SPTS with two ESs inside, but video-stream is not described as it should (there is no ES-info section): https://drive.google.com/open?id=0B27FBYXaYyqAQ2NmNHBKNXZMdXc Input #0, mpegts, from 'udp://239.31.5.205:1234': Duration: N/A, start: 13590.794289, bitrate: N/A Program 1 Metadata: service_name: Service01 service_provider: FFmpeg Stream #0:0[0x100]: Video: h264 (Constrained Baseline) ([27][0][0][0] / 0x001B), yuv420p, 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x101]: Audio: mp2 ([3][0][0][0] / 0x0003), 44100 Hz, stereo, s16p, 128 kb/s For example, stream generated with vlc contains all info inside: https://drive.google.com/open?id=0B27FBYXaYyqATnVXX0p5dU8zY2s Input #0, mpegts, from 'udp://239.31.5.206:1234': Duration: N/A, start: 90599.38, bitrate: N/A Program 1 Stream #0:0[0x43]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 50 tbr, 90k tbn, 50 tbc Actually the same issue is present even if I try to wrap pre-generated h.264 file into MPEG-ts with command: ~/bin/ffmpeg -re -stream_loop 1 -i ~/video2.mpg -c:v copy -vsync drop -c:a copy -f mpegts udp://239.31.5.205:1234 So the question is, how could I set ES info?
