what do you mean by 'stream' ? are you referring to an audio or a video stream within a single file? or are you referring to consuming some type of streamed media, such as rtmp or hls or dash? but generally, yes.. ffmpeg can detect when a stream ends, and usually (depending on options),

Re: [FFmpeg-user] FFplay network stream with low latency

I discovered an option in picamera python module to include the framerate in the SPS headers, so now I will use that instead of raspivid. Plus it’s more flexible, allowing for more advanced text overlays. Now ffplay detects it correctly as 30 tbr, although it shows 60 tbc and it shows

[FFmpeg-user] The concat filter and duplicate frames from prores files

2018-08-05 Thread Nick Ludlam
Hi all, I’ve got some puzzling behaviour when attempting to join a set of prores quicktime files together via the concat filter, and encode down to an mp4. Quicktimes produced by the video editing software we’re using cannot be successfully concatenated without producing duplicate frames. In a

Re: [FFmpeg-user] exponential decay, is it possible?

Every time when the input becomes brighter than the last output frame, the output is set to the input value. If input is below the last output value, then exponential decay. I have a timelapse video of the night sky with meteors. Each meteor is visible only in one frame. I'd like to make them

Hi there. I learned some new ffmpeg tricks today, I guess it's interesting for those who record videos: http://blogologue.com/blog_entry?id=1533406754X26 It's about adding a timestamp-counter to a video, and slowing it down. This was recorded using my phone, but I'm also biking around with an
