ffmpeg override the same file for every second of the video [on hold]
5 février 2017, par Dorin PleavaI want to get one image for every 10 seconds from a livestream/video, but the image should have the same name, meaning I want to override it every cycle.
This is my command :
ffmpeg.exe -i http://iphone-streaming.ustream.tv/uhls/17074538/streams/live/iphone/playlist.m3u8 -bt 20M -s 480x300 -vf fps=1/10 -y photo.jpg
This code works for one image but for the next I get this
"Could not get frame filename number 2 from pattern ’photo.jpg’ (either set updatefirst or use a pattern like %03d within the filename pattern)
av_interleaved_write_frame() : Invalid argument"If I replace photo.jpeg with photo%03d.jpg I get photo001.jpec, followed by photo002.jpeg, etc.

How to get bit stream rate of a mpeg Transport Stream ?
28 septembre 2015, par CompNetHow can we get the bit rate of a transport stream from the
TS
source ? One way is to use a constant bitrate while multiplexing the encoded video into TS stream. But how does the variable bitstream work ?I found the command with ffmpeg like :
ffmpeg -i encoded.mp4 -c copy -map 0 -vbsf h264_mp4toannexb mpegts out.ts
but could not understand the meaning of
-vbsf h264_mp4toannexb
. Can anyone please explain me how does variable bitrate work ?Also, is there any other way we can find the timestamp of each
TS
packet multiplexed in the Transport Stream ?
