Recode a motion-jpeg stream into mpeg-ts?
 
|
Hi,
Sorry, I have a final-user question... (I'm quite far to become a gst developper...) So, may I ask my question here? I'm trying to recode the motion-jpeg stream for a network cam into an mpeg-ts stream (the ultimate wish is to watch this on a DLNA TV via Rygel, but this is another step) For now, I can watch the mjpeg stream via gstreamer: $ gst-launch-1.0 uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! autovideosink It's fine, I'm happy. Now, I try to reencode the stream: $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! video/x-raw, framerate=25/1, width=640, height=480 ! videoconvert ! avenc_mpeg2video ! mpegtsmux ! tcpserversink ../.. /GstPipeline:pipeline0/GstCapsFilter:capsfilter1: caps = video/x-raw, framerate=(fraction)25/1, width=(int)640, height=(int)480 ERROR: from element /GstPipeline:pipeline0/GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source: Internal data stream error. Additional debug info: gstbasesrc.c(3055): gst_base_src_loop (): /GstPipeline:pipeline0/GstURIDecodeBin:uridecodebin0/GstSoupHTTPSrc:source: streaming stopped, reason not-negotiated (-4) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... Freeing pipeline ... So, what's wrong?

In the particular case, if the source material is not 640x480 (your desired destination resolution) you'll have to add videoscale as well next to videoconvert (also add videorate if you are changing the framerate too).

Let's keep the same resolution for now (each step one after the other ;) But I wonder if there is an intrinsic issue about the frame rate... $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! queue ! videorate ! video/x-raw, framerate=5/1 ! videoconvert ! avenc_mpeg2video ! filesink location=test.mpg /GstPipeline:pipeline0/GstCapsFilter:capsfilter0.GstPad:sink: caps = video/x-raw, format=(string)I420, width=(int)1280, height=(int)800, interlace-mode=(string)progressive, multiview-mode=(string)mono, multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono, pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2, colorimetry=(string)1:4:0:0, framerate=(fraction)5/1 /GstPipeline:pipeline0/GstVideoRate:videorate0.GstPad:sink: caps = video/x-raw, format=(string)I420, width=(int)1280, height=(int)800, interlace-mode=(string)progressive, multiview-mode=(string)mono, multiview-flags=(GstVideoMultiviewFlagsSet)0:ffffffff:/right-view-first/left-flipped/left-flopped/right-flipped/right-flopped/half-aspect/mixed-mono, pixel-aspect-ratio=(fraction)1/1, chroma-site=(string)mpeg2, colorimetry=(string)1:4:0:0, framerate=(fraction)0/1 buffering... 0% and this stay at 0% ! Indeed, the original motion-jpeg stream has no frame rate. To be more precise, the network-cam produces pictures at an actual rate varying from 5.5 fps to 6.5 fps... I expected that the "queue" could compensate the jitter... but there should be something else more complicated to do ;-) Does someone has an example on how to manage a mjpeg source an recode it to something else?

Framerate of a motion-jpeg stream
|
|
Hi,
I'd like to handle the motion-jpeg stream of a nework cam. This commands works well and display the stream: $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! video/x-raw, framerate=0/1 ! autovideosink sync=false The point is that mjpeg has no real "framerate"; pictures arrive as they can (well, on the local network this is about at 25fps) Now, let says I want to convert this stream to another format at a given framerate, how to do this? If I add the "videorate" plugin, I get nothing, nothing to display as if it can't feed its buffer... This commands doesn't work (this open the display window, which remains desperately empty): $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! video/x-raw, framerate=0/1 ! videorate ! video/x-raw, framerate=25/1 ! autovideosink sync=false Any idea ?

Hi,
I'm still trying to handle the motion-jpeg stream from my network cam.

Hi Christophe, The multiview thing is just a warning in the debug log, I don't think it should have any effect or cause any problems. You can set fakesink silent=false and pass -v to gst-launch-1.0 to see if you get output buffers on the fakesink (or use fakesink dump=true). As for the pipeline in your previous mail $ gst-launch-1.0 -v uridecodebin uri=... ! video/x-raw, framerate=0/1 ! autovideosink sync=false and $ gst-launch-1.0 -v uridecodebin uri=... ! video/x-raw, framerate=0/1 ! videorate ! video/x-raw, framerate=25/1 ! autovideosink sync=false there shouldn't be any need to specify that caps filter in front of videorate, you just need the one after it to force it to a certain output framerate, so $ gst-launch-1.0 -v uridecodebin uri=... ! videorate ! video/x-raw, framerate=25/1 ! autovideosink sync=false should hopefully work.

Unfortunately I still have issues If I understand well, videorate complains about the lack of timestamp on the input. Ok, this is just a WARN, but I get nothing in my sinks Is there a way to add some timing info on mjpeg decoding? $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! videorate ! video/x-raw, framerate=25/1 ! filesink location=foo.bar or $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! videorate ! video/x-raw, framerate=25/1 ! autovideosink sync=false or $ gst-launch-1.0 -v uridecodebin uri=http://192.168.3.55/mjpg/video.mjpg ! videorate ! video/x-raw, framerate=25/1 ! fakesink dump=true Setting pipeline to PAUSED ...

You must specify the correct format of the received video and then decode it.
