I'm guessing that av_open_input_file() is either deprecated or was never intended to be used in this manner -- more than likely the latter ;) You can use the FFmpeg source to ingest RTSP video streams into mimoLive. And for streaming mostly yuv420 used as pixel format and most of codecs expect this (like mpeg2, mpeg4 avc. I have answered a similar question here FFMPEG API: How to connect to RTSP stream using av_open_input_file? I have two RTP sources (they will be more in the future, but I am starting with these two), sent from two different source in a Janus server. use for CPU usage comparisons; FFMPEG_ARGS - additional arguments to ffmpeg publisher. I am using following command : ffmpeg -i input_file. Options can be set on the ffmpeg/ffplay command line, or set in code via AVOptions or in avformat_open_input. mp4 Or list the inputs normally and use the concat filter:. run to use rtsp stream as the input, and output the transcoded stream over an http stream using mpeg1video encoding. An sdp file that describes the rtp, and indicates which port (on localhost) the rtp will be arriving on 2. sdp and in a second terminal: $ ffplay -protocol_whitelist rtp,file,udp -i out. But if there is no data on the given URL, ffprobe hangs. Improve this answer. I am taking input from pulseaudio and creating an rtp stream. Use a build that supports pthreads, or try TCP instead of UDP. However, if one outputs to a TS file, the output is entirely usable, and it is never good idea to stream raw files over network, I guess when you used mp4 file, ffmpeg probably encodes the output, in case of UDP (or rtp or rtps) you should explicitly tell the ffmpeg to encode stream before output. ffmpeg -re -stream_loop -1 -i input. #1112. mp4 -i rtmp:// -map 0:v -map 1:a output -re will play input.

In LibAV/FFMPEG it's possible to set the udp buffer size for udp urls (udp://) by appending some options (buffer_size) to it. rtsp-stream-converter. With these build options my FFMPEG build does receive and decode rtsp streams--enable-network --enable-protocol=tcp --enable-demuxer=rtsp --enable-decoder=h264. The input rate needs to be set for record if used directly with unifi protect. Here, I also checked with VLC that the codec etc. ffmpeg4. rtp test. ffmpeg handles RTMP streaming as input or output, and it's working well. The read() operation is blocking so the main program is stalled until a frame is read from the camera stream.

Reload to refresh your session. e. 12:1234 For RTSP streams you can specify timeouts in the SDP file. As your -reorder_queue_size increases, so must your -max_delay in order to allow for a longer time to receive packets and then reorder them. So I am trying to feed the captured rtp stream into ffmpeg and get a transcoded output. mp4 Replace 1234 with your port. Using ffmpeg I can open an SDP file using the syntax: ffmpeg -protocol_whitelist file -i file. Part of the problem is that the probing process takes too much for every stream. Tip: "file" in meaning of the ffmpeg can be regular file, pipe, network stream, grabbing device, etc. mp4 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/live. sdp Does anyone know if it is possible to join the stream described in the sdp file without first writing the contents to a file?

I am trying to use rtp streaming using ffmpeg. 1. I have tested just now with a valid rtsp source and it works ok. At the end, RTSP is a control protocol (over TCP) which negotiates the media by means of a SDP. If FFMPEG is not sending RTCP receiver reports, the RTSP server could be terminating the connection? This is all speculation though, use a network sniffer such as wireshark to see what is happening. See the camera specific docs for more info on non-standard cameras and recommendations for using them in Frigate. mp4 and the return I get in the command line is. mp4 at realtime for streaming instead of as fast as possible. avformat_open_input() fail: Invalid data found when processing input Normally if I were using ffplay on the console, I would add the option -protocol_whitelist file,udp,rtp and it would work fine. From the ffmpeg manual: When there are multiple input files, ffmpeg tries to keep them synchronized by tracking lowest timestamp on any active input stream. With the below command the streaming works but I don't know how to adjust this command to specify it needs to use the microphone as input. I'm currently doing a stream that is supposed to display correctly within Flowplayer.

(Requires at least one of the output formats to be rtp). 10. I want to stream some videos (a dynamic playlist managed by a python script) to a RTMP server, and i'm currently doing something quite simple: streaming my videos one by one with FFMPEG to the RTMP server, however this causes a connection break every time a video end, and the stream Unlike RTMP defined as a pure protocol based on FLV, RTSP is a format and a protocol meanwhile.

Failed: cannot open input. Another alternative would be to implement signaling server inside of ffmpeg itself, but then ffmpeg would need to listen on some port, and that port would need to be open in firewalls (that's what signaling server does). This may result in Missed packets when input multiple RTSP streams. 0 update Unifi Protect Cameras had a change in audio sample rate which causes issues for ffmpeg.
