Open nunowar opened 5 years ago

nunowar commented 5 years ago

When using buffer as input, the output video is incomplete, but if i use the same input file as file, the video is ok, some help to find the problem?

Version information

Code to reproduce

let inStream = streamifier.createReadStream(file.Body);

ffmpeg(inStream).inputFormat('gif')
 .outputOptions(['-pix_fmt yuv420p', '-movflags frag_keyframe+empty_moov', '-movflags +faststart'])
 .toFormat('mp4').save('test.mp4')
 .on('error', function(err, stdout, stderr) {
      console.log('Cannot process video: ' + err.message);
 })
 .on('end', function() {
      console.log('Finished processing');
 });

Expected results

Convert all video.

Observed results

The output video is incomplete, just have 1 second.

Any update on this ?

Related to #1013 for GIFs as inputs you have to set the input format to gif_pipe, this is not mentioned in FFmpeg's Docs unfortunately.
