FFmpeg capturing 1 FPS thumbnails
30 juin 2019, par GediminasI’m trying to programmatically export a series of thumbnail images (one image per-second) I’m not worried about the actual footage conversion and image file creation. My interest is in how would it be better to capture a valid 1 fps frame. (with no artifacts)
This is possible using FFmpeg’s command line like this :
ffmpeg -i test.mp4 -vf fps=1 out%d.png
So while looking at the FFmpeg’s source code I’ve noticed that it’s using a thing called filters. While filters can do a lot of cool stuff, I’m not sure if using those wouldn’t be too much of an overhead for a relatively simple task like this ?
I mean, while using filters, to get a correctly decoded frame (with no artifacts) FFmpeg still needs to decode all frames contiguously anyway ? So maybe in my situation it’s better to not use filters and decode frames contiguously while monitoring frame’s PTS ?

doc/APIchanges : document newly added buffersrc field
11 janvier 2024, par Niklas Haasdoc/APIchanges : document newly added buffersrc field
This was accidentally removed in a prior revision of the series,
alongside the corresponding (separate) version bump. Instead coalesce it
into the follow-up commit's entry, since that's the lowest version
actually supporting the new fields. -
Get x264 options from stream
29 juillet 2014, par HardRockI have a problem with H264 encoding, actually with libx264 :(
I want to encode series of images from web camera into h264 and send stream to chines DVR. Problem is DVR can’t decode my stream. I tried to adjust (using h264stream_analyzer) SPS and PPS in libx264 to match SPS and PPS headers from "correct stream", produced by other chinese DVR’s and IP cameras. But no luck :( Looks like problem in bitstream.
My stream and "correct" stream - are both may be converted and played with avconv (ffmpeg), for example.
Transport is ok. If i send "correct stream" - DVR understand it. Problem in stream.One strange thing - "correct stream" contains a lot of 28 and 29 slice types. From h264 specification this is must be "fragmentation" units. But my stream contains only P and I slices, но fragmens.
So how i can get exact stream encoding parameters from existing sample stream ? It may be difference in x264 versions ?
