when i want to save rtsp stream to file i got lot of error like
{{{
[h264 @ 098e5c80] RTP: missed 198 packets
[h264 @ 0ad4f500] error while decoding MB 21 9, bytestream (-5)
}}}
so the file in loq quality and skip on frame
the command i run :
{{{
ffmpeg -i rtsp://x.x.x.x/video -rtsp_stransport udp file.264
}}}
some facts:
1)I can get this stream only on rtsp udp, (not tcp )
2) When i "record" this stream to file with OpenRtsp/live55 I get no error
, and exelent quality.so the answer "udp is not good protocol, it's loose
package is not correct (another lib do it well)
3) i get the same error if I save to file.avi/file.mp4/file.ts
4)i don't want to use -c:v copy because I want to apply some filters.(v:c
copy not always fix the problem)
5)on resolution under 1080x1920 I got better results.
thank you all!
