• FFMPEG to periscope or twitter

  18 mars 2021, par Jintor

  In twitter studio to stream they specify

  


  RTMP URL rtmp ://va.pscp.tv:80/x

  


  RTMPS URL rtmps ://va.pscp.tv:443/x

  


  but when I do

  


  ffmpeg -re -i file.webm -c:v libx264 -preset ultrafast -vf "scale=-2:1080" -g 60 -pix_fmt yuv420p -c:a aac -b:a 128k -ac 2 -r 30 -vb 900k -minrate 900k -maxrate 900k -bufsize 900k -ar 44100 rtmps://va.pscp.tv:443/x/


  


  I get this error

  


  Unable to find a suitable output format for rtmps://va.pscp.tv:443/x/key: Invalid argument


  


  I tried with and without the x but nothing goes, still same error

  


  how to fix this

  


• Transcoding with the GCP Transcoder API results in a time gap

  3 mars 2021, par banyan

  I've been trying GCP's Transcoder API and having trouble with the time randomly becoming shorter than specified in certain cases.

  


  The specific cases are as follows :

  


  

  1. Specifying startTimeOffset and endTimeOffset (cut off 2 seconds before and after the video)

  


  2. fMP4 is used as container

  


  3. input video is mp4 with screen recording on iPad Pro

  


  


  For example, if I don't specify startTimeOffset and endTimeOffset, the time will not be shortened. Also, there is no problem when MPEG2-TS is specified for container. There may be a problem with the video itself, but I haven't found a clue how to set it up.

  


  I'm not sure whether this is a problem with the Transcoder API or with me.

  The following is a ffprobe of the resulting manifest file, which is 2 seconds shorter than specified. (expected : 00:02:47.00, actual : 00:02:45.00) In this case, it's a 2-second gap, but it can be 10 seconds or 30 seconds, and it varies from video to video.

• PHP ffmpeg Image to Video

  2 mars 2021, par Metin Saraç

  I want to create a Video with Image in php ffmpeg.

  


  My code is as follows,

  


  $video = $ffmpeg->open('image1.jpg');
$video->filters() ->resize(new FFMpeg\Coordinate\Dimension(1080, 1080))->synchronize();
$format = new FFMpeg\Format\Video\X264();
$format->setKiloBitrate(1000)->setAudioChannels(2)->setAudioKiloBitrate(256);
$video->save($format, 'video.avi');


  


  I want total video duration and background sound to my code, but I couldn't find a suitable solution. Can you help me ?

  


  Respects.
