Revision 939791a129 : Modify encode breakout for static frames Thank Paul for the suggestions. While
6 septembre 2013, par Yunqing WangChanged Paths :
Modify /vp9/encoder/vp9_firstpass.c

Modify /vp9/encoder/vp9_rdopt.c
Modify encode breakout for static framesThank Paul for the suggestions. While turning on static-thresh
for static-image videos, a big jump on bitrate was seen. In this
patch, we detected static frames in the video using first-pass
stats. For different cases, disable encode breakout or reduce
encode breakout threshold to limit the skipping.More modification need be done to break incorrect partition
picking pattern for static frames while skipping happens.Change-Id : Ia25f47041af0f04e229c70a0185e12b0ffa6047f

ffmpeg - Continuously stream webcam to single .jpg file (overwrite)
8 octobre 2016, par GermanunkolI have installed ffmpeg and mjpeg-streamer. The latter reads a .jpg file from /tmp/stream and outputs it via http onto a website, so I can stream whatever is in that folder through a web browser.
I wrote a bash script that continuously captures a frame from the webcam and puts it in /tmp/stream :
while true
do
ffmpeg -f video4linux2 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 -vframes 1 /tmp/stream/pic.jpg
doneThis works great, but is very slow ( 1 fps). In the hopes of speeding it up, I want to use a single ffmpeg command which continuously updates the .jpg at, let’s say 10 fps. What I tried was the following :
ffmpeg -f video4linux2 -r 10 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 /tmp/stream/pic.jpg
However this - understandably - results in the error message :
[image2 @ 0x1f6c0c0] Could not get frame filename number 2 from pattern '/tmp/stream/pic.jpg'
av_interleaved_write_frame(): Input/output error...because the output pattern is bad for a continuous stream of images.
Is it possible to stream to just one jpg with ffmpeg ?
Thanks...
