Saving video from Android camera as local .mjpeg file
It appears that there is a threshold with regards to jpeg quality that is required for an MJPEG file to play. Changing, im.compressToJpeg(r, 5, jpegByteArrayOutputStream); to, im.compressToJpeg(r, 75, jpegByteArrayOutputStream); results in a valid MJPEG file. ...
Constructing a JPEG image from RTSP MJPEG stream
There were extra 0x0d in the data that I was getting from curl. All the extra 0x0d were before a 0x0a. I removed all the 0x0d that came before a 0x0a and then my algorithm worked fine. I figured this out by comparing the output of the data given by...
Incompatible pixel format YUV420P with mjpeg
You get the warning because ffmpeg's internal JPEG encoder expects JPEG-range input, and does so using the old (deprecated) pixfmt YUVJ420P instead of the new method (setting pixfmt=YUV420P with color-range). However, that brings us to the core of this question: why are you re-encoding JPEG source images to JPEG? You...
MjpegView with other XML layouts
java,android,xml,video-streaming,mjpeg
I figured it out what was my problem... I was trying to do: mv = (MjpegView) findViewById(R.id.mv); setContentView(R.layout.activity_test); And was getting a NullPointerException.. I changed to: setContentView(R.layout.activity_test); mv = (MjpegView) findViewById(R.id.mv); And now everything is working like is supposed to be :)...
Node.js - MJPEG TCP stream to base64 images
node.js,tcp,socket.io,base64,mjpeg
chunk.toString() converts the binary Buffer to a utf8-encoded string (by default), so for binary image data that will probably cause you some problems. Another option that might help simplify things for you is to use the dicer module. With that, your code may look like: var Dicer = require('dicer'); var...
GStreamer Tee : x264enc + jpegenc -> deadlock?
Found the answer here : http://gstreamer-devel.966125.n4.nabble.com/Pipeline-Freezes-When-Adding-In-Tee-With-x264enc-td4301890.html Using "x264enc tune=zerolatency" made it working !...
Is it possible to have two images in a single frame in motion jpeg?
Yes, motion Jpeg supports interlaced format. If the jpeg file is half of the full video size, will mean that the mov is interlaced, and you cannot use -vcodec copy to extract the frames. Try ffmpeg -deinterlace or use yadif filter.
OpenCv Python frame empty in mjpeg stream from webcam
python,opencv,python-3.x,stream,mjpeg
Could I suggest the following type of approach: try: ret, frame = cap.read() except: ret, frame = (-1, blackframe) try: ret2, frame2 = cap2.read() except: ret2, frame2 = (-1, blackframe) try: ret3, frame3 = cap3.read() except: ret3, frame3 = (-1, blackframe) try: ret4, frame4 = cap4.read() except: ret4, frame4 =...
Safari open and close img MIME type multipart / x-mixed-replace streaming on demand
javascript,dom,safari,multipart,mjpeg
In case you are still looking for an answer, I had the same problem in older version of chrome (not tested with safari but may be the same solution) and the only thing that worked for me was calling window.stop(). This will stop all connection in the page so if...
packing MJPEG into MPEG-TS
I think you cannot pack MJPEG inside MPEG2-TS. But you can pack it in other formats wiki: Unlike the video formats specified in international standards such as MPEG-2 and the format specified in the JPEG still-picture coding standard, there is no document that defines a single exact format that is...

Solutions to stream from a decklink card to browsers (Gstreamer -> TCP MJPEG -> ?)
http,browser,gstreamer,live-streaming,mjpeg
I got the websockets solution working, thanks to the node Dicer module (and thanks to mscdex on this post ). So here is what I did : 1°) Stream my Decklink card's video over TCP whith GStreamer : gst-launch -v decklinksrc mode=10 connection=0 ! deinterlace ! videorate ! videoscale !...
V4l2 MJPEG Chroma Subsumpling
v4l2 itself provides a very thin layer around the actual video data that is transferred: it will simply give you the formats that the camera (the hardware!!) delivers. so if your hardware offers two distinct formats, then there is no way that v4l2 will offer you anything else. you might...
