ffmpeg mapping to mkv introduces "fake" delay relative to video
1er août 2016, par JMorI need to map this x.264 clip into a matroska container using ffmpeg :
ffmpeg -i f-0.mp4 -c copy f-0.mkvHere is the ffmpeg console output :
ffmpeg -i f-0.mp4 -c copy f-0.mkv

...The result seems good, playing with well synchronized audio and video. However, MediaInfo shows a new item under Audio (that the original clip didn’t have) :

I am concerned that this information (Delay relative to video) be used by some players or other applications as a delay that should be corrected. Is there a way to prevent this from happening ?

how to use a video stream as input in python/opencv programme
11 juillet 2016, par vasu guptaI am able to stream and receive webcam feed in two terminal via udp
command for streaming :
ffmpeg -i /dev/video0 -b 50k -r 20 -s 858x500 -f mpegts udp://127.0.0.1:2000command for recieving :
ffplay udp://127.0.0.1:2000Now i have to use this received video stream as input in python/opencv how can i do that.
I will be doing this using rtp and rstp as well.
But in case of rtsp it is essential to initiate the receiving terminal, but if I do that then port will become busy and my program will not be able to take the feed.How could it be resolved.
I am currently using opencv 2.4.13, python 2.7 in ubuntu 14.04 -
Using FFmpeg to encode 2pass mp4
