I know that my question is too open but any suggestions how can I keep progressing? According my research (for this one I'm not sure if I'm looking where I should) it's part of ijkplayer player that should be based on ffmpeg but strangely ffmpeg can't recognize the stream. It seems that libijkffmpeg.so is the one processing the stream (the string bt470bg is found only inside it). In the resources directory there are the following libs: I have downloaded the andorid app ( ) and have de-compile it. There is andorid and iPhone apps to watch the stream from the camera. There is no single package containing FFD8 but there are many containing FFD9, so I can't find out the beginning of the frame to see if some headers there could help me. From what I have read each frame should start with FFD8 and should end with FFD9. I have a wireshark dump of some seconds of streaming (while was trying to play it with VLC). Stream #0:0: Video: mjpeg, none(bt470bg/unknown/unknown), 90k tbr, 90k tbn, 90k tbcĬould not write header for output file #0 (incorrect codec parameters ?): Invalid argument

Could not find codec parameters for stream 0 (Video: mjpeg, none(bt470bg/unknown/unknown)): unspecified sizeĬonsider increasing the value for the 'analyzeduration' and 'probesize' options

ffmpeg also can't detect the correct codec to be used: $ ffmpeg -i rtsp://192.168.1.1:7070/webcam -vcodec copy /tmp/abc.mp4įfmpeg version n4.2.2 Copyright (c) 2000-2019 the FFmpeg developersīuilt with gcc 9.3.0 (Arch Linux 9.3.0-1)Ĭonfiguration: -prefix=/usr -disable-debug -disable-static -disable-stripping -enable-fontconfig -enable-gmp -enable-gnutls -enable-gpl -enable-ladspa -enable-libaom -enable-libass -enable-libbluray -enable-libdav1d -enable-libdrm -enable-libfreetype -enable-libfribidi -enable-libgsm -enable-libiec61883 -enable-libjack -enable-libmfx -enable-libmodplug -enable-libmp3lame -enable-libopencore_amrnb -enable-libopencore_amrwb -enable-libopenjpeg -enable-libopus -enable-libpulse -enable-libsoxr -enable-libspeex -enable-libssh -enable-libtheora -enable-libv4l2 -enable-libvidstab -enable-libvorbis -enable-libvpx -enable-libwebp -enable-libx264 -enable-libx265 -enable-libxcb -enable-libxml2 -enable-libxvid -enable-nvdec -enable-nvenc -enable-omx -enable-shared -enable-version3 It supports RTSP protocol on port 7070 (the only one opened port). From what I have found so far the camera is using IP 192.168.1.1.
#FFMPEG RTSP TEARDOWN PC#
If your PC ip is 192.168.0.10, then the rtsp stream is played by this command: vlc rtsp://192.168.0.I'm trying to stream video from endoscope camera YPC99 on linux PC using the WiFi connection. Here's the ffmpeg|vlc command: ffmpeg -thread_queue_size 1024 -f video4linux2 -input_format mjpeg -i /dev/video0 -r 30 -f alsa -ac 1 -thread_queue_size 1024 -i hw:1,0 -acodec aac -vcodec libx264 -preset ultrafast -crf 18 -s hd720 -vf format=yuv420p -profile:v main -threads 0 -f mpegts -|vlc -I dummy -sout='#std -sout-all -sout-keep'

If you're using a file as input, you won't need all that v4l2 and alsa stuff. You will have to adjust the command for your device or file. I've also had audio-sync issues with some of the other methods, where this method always has perfect audio-sync. Piping through vlc must be CPU-friendly, because my old dual-core Pentium CPU is able to do the real-time encoding with no dropped frames.
#FFMPEG RTSP TEARDOWN DRIVER#
I'm using a video capture HDMI>USB device that sets itself up on the video4linux2 driver as input. I've tried both, but the http ts stream seems to work glitch-free on my playback devices. In the example I use an mpeg transport stream (ts) over http, instead of rtsp.
#FFMPEG RTSP TEARDOWN INSTALL#
If you don't have these installed, you can add them: sudo apt install vlc ffmpeg Another streaming command I've had good results with is piping the ffmpeg output to vlc to create a stream.
