Filter generated by size() do not work with h264_vaapi codec #1120
Open
Description
Version information
- fluent-ffmpeg version: 2.1.2
- ffmpeg version: 4.3.2
- OS: linux
Code to reproduce
var FfmpegCommand = require('fluent-ffmpeg');
var command = new FfmpegCommand();
command .input('in.mkv')
.videoCodec('h264_vaapi')
.inputOptions([
'-hwaccel vaapi',
'-hwaccel_output_format vaapi',
'-vaapi_device /dev/dri/renderD128'
])
.size('?x720')
.output('out.mp4')
.on('start', (cmd) => {
console.log(cmd)
})
.on('error', function(err, stdout, stderr) {
console.log('Cannot process video: ' + err.message);
console.log('stderr: ' + stderr);
})
.run()Expected results
Generated filter for resize should use scale_vaapi instead of scale.
Expected ffmpeg command line:
ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -i in.mkv -y -vcodec h264_vaapi -filter:v scale_vaapi=w=trunc(oh*a/2)*2:h=720 out.mp4
Observed results
Ffmpeg fail because scale filter does not exists for vaapi encoders and scale_vaapi should be used instead.
Observed ffmpeg command line:
ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -i in.mkv -y -vcodec h264_vaapi -filter:v scale=w=trunc(oh*a/2)*2:h=720 out.mp4
Result of code above
ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -i in.mkv -y -vcodec h264_vaapi -filter:v scale=w=trunc(oh*a/2)*2:h=720 out.mp4
Cannot process video: ffmpeg exited with code 1: Conversion failed!
