    28 juillet 2021, par Jacob

    I have successfully remotely viewed the stream using ffplay -rtsp_transport tcp rtsp ://streamurl.

    However, when playing the stream the a VCL player or trying to add the stream to my AWS instance of Ant media server. The stream does not go through. On ant media server there is no errors the stream connects but its just a black screen. On the VCL player I am getting the error :

    


    VLC is unable to open the MRL 'rtsp://{streamurl}'


    


    I currently have an identical camera setup the exact same way working fine. The only difference is there on different LAN's with different ISP's.

    


  • Issue with audio codec in ffmpeg

    13 juillet 2021, par bloodstar

    To my little knowledge i believe this is an audio codec issue however since im not really familiar with ffmpeg, anything could be wrong.

    Should the code be changed to convert the audio to flac prior to convert the clip ? thanks

    


  • ffmpeg ignores video stream bitrate input doubling the -b:v parameter that I set during encoding

    27 juillet 2021, par QRrabbit

    My question is, how do I force ffmpeg to encode a video at a specific kb/s ?
The problem is that my output is almost twice the size of the input 1.2Gb

    


    This is my input (from ffprobe) :

    


        Stream #0:0(eng): Video: prores (4444) (ap4h / 0x68347061), yuva444p12le(tv, bt709, progressive), 1920x1080, 316752 kb/s, SAR 1:1 DAR 16:9, 29.97 fps, 29.97 tbr, 30k tbn, 30k tbc (default)
    Metadata:
      creation_time   : 2021-07-26T23:59:52.000000Z
      handler_name    : Apple Video Media Handler
      timecode        : 00:00:00:00


    


    My encoding command string :

    


    ffmpeg -i input.mov -i watermark.png -filter_complex " \
[0][1]overlay=50:50:enable='between(t, 0, 100)'" -vcodec prores_ks -profile:v 4 \
-pix_fmt yuva444p12le -b:v 316752 -maxrate 316752 -minrate 316752 -r 29.97 \
-top 1 -color_range 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 \
-map_metadata 0 -c:a copy -timecode 00:00:00.00 -c:s copy -y output.mov


    


    This is the output :

    


        Stream #0:0: Video: prores (4444) (ap4h / 0x68347061), yuva444p12le(tv, bt709, progressive), 1920x1080, 591460 kb/s, SAR 1:1 DAR 16:9, 29.97 fps, 29.97 tbr, 11988 tbn, 11988 tbc (default)

      handler_name    : VideoHandler
      timecode        : 00:00:00:00


    


    Things I've tried :
-b:v 316752925 -maxrate 316752925 -minrate 316752925
-b:v 316752 -maxrate 316752 -minrate 316752
-maxrate 316752925 alone or in various combination with the above.

    


    Any help is greatly appreciated,
