[FFmpeg-user] Help required in vp9 streaming and capturing on LAN
Hi, I am streaming videos on LAN using VP9 encoding (and .sdp file on client-side) but able to capture the videos in a single file (at the client). How can I capture those video files as a sequence of videos? ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Re: [FFmpeg-user] facing max delay reached. Need to consume packets. RTP missed packets
Hi Chris, I have observed that the machine that is receiving stream is lack behind as the streaming server approaches the fps count of around 200 or above when the client starts streaming the fps. Kindly guide me. should I replace the client machine? Thanks.

[FFmpeg-user] facing a error/issue in compression efficiency under h.265
Hi, I am comparing the compression efficiency of H.264 and H.265 codecs. I have studied many research papers showing that the compression efficiency of H.265 is much better than H.264. But I am not able to get the same results. I am trying to compress 664 YUV 4:2:0 video sequence with ffmpeg under H.264 and H.265 codecs and got the resultant videos of following sizes: H.264: 5.58 MB H.265: 6.66 MB I am using the following commands for compression: H.264: ffmpeg -i video.y4m -c:v libx264 -an -strict experimental -preset slow -CRF 30 - b:v 800k -f mp4 output.mp4 and for H.265: ffmpeg -i video.y4m -c:v libx265 -an -strict experimental -preset slow -CRF 30 - b:v 800k -f mp4 output1.mp4 Kindly tell me what is the issue. Waiting for the kind response.
