Streaming RTP packets using SDP to ffmpeg
4 avril 2017, par Johnathan KanarekI have RTP packets in node.js server and I want to forward them to ffmpeg.
I generate SDP files in the node.js server side and execute ffmpeg with the SDP as input.SDP :

ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i input.sdp -vcodec copy -acodec aac -f flv rtmp://127.0.0.1:1935/live/myStreamI get weird video that plays some vidoe, then get stuck, then plays some audio, back to video and so on, it never plays both video and audio together.
BTW, when I created separate SDP files for the video and the audio and stream them as two inputs into the same output, I get valid stream but the audio is not in sync (about a second offset).
ffmpeg -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i video.0.sdp -max_delay 5000 -reorder_queue_size 16384 -protocol_whitelist file,crypto,udp,rtp -re -i audio.1.sdp -vcodec copy -acodec aac -shortest -y output.mp4What is wrong with my SDP ?
I tried changing analyzeduration, probesize, rtbufsize, vsync, framerate,
I even tried to remap the streams using -map 0:v -map 0:a,
nothing helpedI also tried to use RTSP server, see log :

How do I properly reduce the resolution of a 360 video using ffmpeg ?
10 avril 2017, par user3799235I have tried reduction with the following technique from a scale of
2048:1024with something like :ffmpeg -i eagle360half.mp4 -vf scale=1024:512 video360_1024.mp4however the playback then becomes warped and warbly (visually similar to a bad vhs tape). I can only speculate that this has something to do with the meridians and equirectangular projections. How would I properly scale/ reduce resolution of a 360 video usingffmpeg, or is this possible with some other cli tool ?Here is the output of mediainfo, ffmpeg, and then mediainfo again :
