[FFmpeg-user] ffplay RTSP listen mode with UDP
Hi, i'm trying to use RTSP to push video from client to server. it works on TCP, but fails on UDP. server side: > ffplay.exe -rtsp_flags listen rtsp://0.0.0.0:14000/test client side (TCP mode): > ffmpeg.exe -re -i -rtsp_flags prefer_tcp -f rtsp rtsp://SERVER_IP:14000/test cliend side (UDP mode): > ffmpeg.exe -re -i -f rtsp rtsp://SERVER_IP:14000/test when I open the ffmpeg in the client side in TCP mode, everything works, and i see the video stream in the server. But when i open the ffmpeg in the client side in UDP mode, the server writes an error: "bind failed error number -10048" (already in use) to try and investigate this problem a little bit, i set RTSP min port in the server to 6001. the result was the same, yet i could see (using netstat) ffplay listening on 6001 in UDP (and still writes the same binding error). seems like something in the RTSP reverse mode is not fully compatible with UDP mode, and it tries to bind the same port twice. is there a workaround to this matter? tested with Zeranoe build 20180307-5ab0ecf Roee. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
Re: [FFmpeg-user] using -vtag on input files
just mentioning, adding | OUT_INPUT to vtag option indeed sort it out. i hope it will get into git-master one day :) thanks 2015-04-02 19:32 GMT+03:00 tim nicholson nichot20-at-yahoo@ffmpeg.org: On 02/04/15 16:45, Carl Eugen Hoyos wrote: tim nicholson nichot20-at-yahoo.com at ffmpeg.org writes: ffmpeg.exe -f rawvideo -vcodec rawvideo -s 704x576 -r 25 -pix_fmt yuv420p -vtag YV12 -i raw.yuv -f avi -qscale 0 out.avi Ahh, so you are using the pix_fmt to specify the input...

In oreder to make amends I think I have tracked the issue down It looks like the merge 5743095c line 3043 from avconv made it at output only option... needs an OPT_INPUT | OPT_OUTPUT instead of OPT_OUTPUT One possible work-around is of course to remux to nut with (output) option vtag.

Re: [FFmpeg-user] using -vtag on input files
first, since my rawvideo input is YV12 and there's no such pix_fmt, yuv420p without vtag results with a blue-pink video output. second, before vtag supported input files, i had to convert the file first to avi with -vcodec copy, and then convert it to mpeg4 or something, which takes forever. i think this thread could shed some light on this matter (last message is the most important i think): http://ffmpeg-users.933282.n4.nabble.com/convert-YV12-stream-to-ProRes-td4665890.html Roee. 2015-04-02 17:53 GMT+03:00 tim nicholson nichot20-at-yahoo@ffmpeg.org: On 02/04/15 15:22, Roee Kashi wrote: Hi, with the older ffmpeg version (described earlier), my command line looks like this: ffmpeg.exe -f rawvideo -vcodec rawvideo -s 704x576 -r 25 -pix_fmt yuv420p -vtag YV12 -i raw.yuv -f avi -qscale 0 out.avi Ahh, so you are using the pix_fmt to specify the input...
