If I remove "-f flv" ffmpeg fails, I get: [NULL @ 0x57c1c40] Unable to find a suitable output format for 'rtmp://<ip-address>/<name-nginx>' rtmp://<ip-address>/<name-nginx>: Invalid argument and if I remove "-codec:v libx264" ffmpeg again fails to run and gives this error: Codec AVOption preset (Configuration preset) specified for output file #0 (rtmp://<ip-address>/<name-nginx>) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream. Stream mapping: Stream #0:0 -> #0:0 (dvvideo (native) -> flv1 (flv)) Stream #0:1 -> #0:1 (pcm_s16le (native) -> aac (native)) [flv @ 0x63f3100] bitrate above max bitrate Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height Conversion failed! thankyou for your help so far on this. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
