ffmpeg conversion x264 [error] : malloc of size 769152 failed
18 décembre 2014, par prashanthpI am trying to convert video recorded from Android smart watch (.mp4 format) to a format (.mp4) which playable on all browsers. The video recorded from smart watch is not playing in the browsers. so, i’ve used ffmpeg to convert in into a playable mp4 format.
But sometimes it is showing error as

ffmpeg stream input sdp shows warning keyframe missing
27 mars 2021, par Doua BeriI'm using ffmpeg 4.3.2.
I'm trying to forward a stream to a rtmp server having sdp file as input


Opening the sdp file with VLC everything is working great. The same thing happens when I use ffplay


ffplay -i rtp-forwarder.sdp -protocol_whitelist file,udp,rtp


The problem starts when I start streaming to a rtmp server. The audio is good but the video is just a black screen. I event tried to stream to youtube rtmp server but it didn't work.


I'm new to ffmpeg. Let me know if I'm missing something.


I'm using this command


ffmpeg -protocol_whitelist file,crypto,udp,rtp -re -i rtp-forwarder.sdp -c:v libx264 -b:v 3000k -maxrate 3000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://localhost/live/test


The sdp file content is like this


v=0
