ffmpeg usb Web cam recording terminates randomly before set duration
16 mars 2018, par pomptondriveThe output of this script is just fine ; it’s pretty much what I want. But it seems to terminate randomly. My next step will be to try this on another computer to see if the issue persists.
My configuration :
Dell Precision laptop, m4400
2x Intel(R) Core(TM)2 Duo CPU P8600 @ 2.40GHz
Linux Mint 18.3 Sylvia
Kernel : Linux 4.4.0-116-generic (x86_64)
Card : NVIDIA G96GLM [Quadro FX 770M]
ffmpeg version 2.8.11-0ubuntu0.16.04.1
USB Camera-B4.09.24.1 Sony Playstation EyeAnd this is the script that I’m running - the last time it recorded for about three hours and forty-five minutes, before that it was about 55 minutes ; once it ran five and a half hours :
#!/bin/bash
echo "This is a shell script to make a timelapse video."
ffmpeg \
-f v4l2 -input_format yuyv422 -video_size 640x480 -framerate 5 -t 09:00:00 -i /dev/video0 \
-vf "select=not(mod(n\,5)),setpts=N/(60*TB),fps=60, drawtext=fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSansMono.ttf:text='%{localtime\:%T}':x=20:y=20:fontcolor=white" \
-c:v libx264 -preset superfast -crf 23 -pix_fmt yuv422p -g 15 -keyint_min 15 \
-f mpegts /media/dkm/OneTB/Video/Timelapse_$(date +%Y-%m-%d_%H.%M.%S).tsAny suggestions would be appreciated. Thanks !

libavcodec/xsubenc.c : Fix bounding box coordinates
7 novembre 2013, par Erik Olofssonlibavcodec/xsubenc.c : Fix bounding box coordinates
Fix coordinates of the lower right corner of the text area.
Note that the coordinates are redundant as the size and
position of the text area are known.
Many decoders (including Sony Playstation 3, VLC and FFmpeg)
ignore the redundant coordinates.
Some hardware decoders need them for correct playback.Verified on Philips DVD player models HTS7201 and DVP3380.

Capturing video over USB/HDMI/Thunderbolt
12 novembre 2016, par YatkoLooking for a solution for capturing video over USB/HDMI/Thunderbolt from a digital output (e.g. digital camera) to a computer, Mac and/or Windows.
The goal is to have an URL to a real-time video stream (e.g. IP/PATH/ ?.mp4) that we can further process/transcode/send to a media server.
I’m looking for tips and ideas -similar to the method below-, maybe someone met a new project that’s focusing on capture-cards and devices, that does’n need a custom FFmpeg build. Something different.
- we can capture the HDMI stream form a GoPro, using a Blackmagic Intensity Shuttle and DeckLink SDK with custom FFmpeg build using
--extra-cflags and --extra-ldflags
and the rest is straightforward
Is there any tool, open-source project, something that’s made for this purpose ? Maybe something that also supports the Elgato Game Capture HD60 as well ? Any experimental projects for capturing and processing the incoming video over USB/HDMI/Thunderbolt ?
The ultimate goal is live streaming to Wowza, using Cameleon live and a Sony Alpha a7S.
