ffmpeg : recording audio + video into separate files, pressing 'q' or ctrl-C, audio is truncated
9 août 2018, par zzzeekTrying to record from the camera and sound card at the same time. If I use the "-t" option with a fixed time, both streams come out fine. If I try to break out while it’s recording, by pressing either ’q’ or ctrl-C, the audio stream is cut typically 5 seconds short.
I’ve tried many many options, codecs, -presets, combinations of everything, changing the order of the streams, usually with no luck. the thing that works the "best" is -preset ultrafast -threads 0, however I find when using these options, the program doesn’t exit cleanly and I can’t find documentation for what "-threads 0" really means (even though its name seems obvious).
Here’s the basic command :
ffmpeg -y -f alsa -i default -f v4l2 -framerate 25 -video_size 640x480 -i /dev/video0 -map 0:a out.wav -map 1:v out.mkv

ffmpeg - Seek to absolute time stamp in MPEG DASH segment [closed]
30 mai 2024, par iBentI need to extract short audio segments at specific time stamps from specific dash segments.


I tried the following :


ffmpeg -ss 00:10:00 -i segment_x.m4s -t 10 out.mp3



-ss
seeks relative to the segment's start time however, and not absolutely.
That absolute time data is there however as ffmpeg prints it during the conversation like this :

Duration: 00:10:14.01, start: 595.018667, bitrate: 7 kb/s



How can I make ffmpeg extract the audio from exactly
00:10:00
to00:10:10
?

Why ffmpeg encoded video is void the first second ?
18 septembre 2023, par SkizZOi am using a bash script to save a short video from an HIKVision cam with homeassistant when the doorbell is pressed.


Here is the commad :


ffmpeg -fflags +genpts -y -ac 1 -channel_layout mono -rtsp_transport tcp -hide_banner -loglevel info -err_detect ignore_err -i "rtsp://$user:$dvrpasswd@$dvraddress:554/Streaming/channels/${camnumber}01" -map 0:v -map 0:a? -ar 44100 -filter:a "volume=$volume" -t $seconds -acodec aac -vcodec copy $filepathname



It results in a video without the preview-frame, who starts at 1sec. (the timeline also can't be fully rewinded) :




This behaviour (in photo) happens on mobile phones, the time shift happen both on windows and android.
