ffmpeg with two input rtmp streams with overlay causing 5 sec delay
13 juin 2019, par GoodStudentI’m using
ffmpeg
on merging two videos, usingoverlay
taking input from twortmp
streams getting lag of 5 seconds in one of the videos in stream3 .Below is the command I’ve tried
ffmpeg -i rtmp://stream1 -i rtmp://stream2
-filter_complex "[0:v]scale=1280:720;[1:v]scale=320:180[v1];[v0][v1]overlay=eof_action=pass[out1]"
-map [out1] -f flv rtmp://stream3I’m expecting less than 1 sec lag in overlay as individual streams are getting less than 1 sec lag

Revision 5daef90efc : skip un-neccessary motion search in the first pass This patch allows the encode
4 juin 2014, par Pengchong JinChanged Paths :
Modify /vp9/encoder/vp9_firstpass.c
skip un-neccessary motion search in the first passThis patch allows the encoder to skip the
un-neccessary motion search in the first pass. It
calculates the error of the zero motion vector using
the last source frame as reference and skips the
further motion search in the first pass if the error
is small.The encoding speedup of the first pass for slideshow
videos is over 30%. Borg test shows the overall PSNR
performance remain approximately the same (derf -0.009,
hd 0.387, yt 0.021, stdhd 0.065). Individual clips may
have either PSNR gain or loss. The worst PSNR perfomance
is from yt set, with a PSNR loss of -1.1.Change-Id : I08b2ab110b695e4689573b2567fa531b6457616e

How do I use ffmpeg on a directory of files and have the new files retain the same name, using Bash ? [duplicate]
31 janvier 2021, par ktbhopefully this will be a relatively straightforward question.


I have a directory of files. The files are mkv files that contain .vtt subtitles. I want to change the vtt subtitles into .srt subtitles. Ideally the mkv files should retain the same names at the end of the process.


I have this Bash command that uses ffmpeg :


ffmpeg -i input.mkv -c copy -c:s srt out.mkv



This command works on an individual file, in terms of giving me a new file with the correct srt subtitles muxed in.


However it does not :


- 

- let me wildcard the mkv file (I have to specify the input.mkv file)
- let me keep the name of the original mkv file






Could someone help please ? I'm thinking it would be a relatively simple Bash loop (for x in *.mkv...) but any help would be most gratefully received. I really want the output files to have the same name as the input files at the end of the process. Thank you.
