Revision 734c5ffa2c : Apply constrained partition search range to non-RD mode decision This commit en
23 avril 2014, par Jingning HanChanged Paths :
Modify /vp9/encoder/vp9_encodeframe.c
Apply constrained partition search range to non-RD mode decisionThis commit enables a chessboard pattern for partition search. All
the black blocks run regular partition search ranging from 8x8 to
32x32. The rest white blocks take the nearby blocks’ information
to adaptively decide the effective search range.The compression performance for rtc set at speed -5 is down by 1.5%.
For pedestrian 1080p at speed -5, the runtime goes from 41594 ms to
39697 ms, i.e., about 5% faster.Change-Id : Ia4b96e237abfaada487c743bca08fe1afd298685

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

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...
