FFmpeg.AutoGen decoding an image using av_image_copy_to_buffer
28 juin 2022, par SteveI try to use
FFmpeg.AutoGen.av_image_copy_to_buffer
to get decoded data into my application defined frame_buffer like so :

bytes_decoded = ffmpeg.av_image_copy_to_buffer(frame_data, buffer_size, frame->data, frame->linesize, 
 codCtx->pix_fmt, codCtx->width, codCtx->height, 1);



However the type of the parameter
frame->data
is of typeFFmpeg.AutoGen.byte_ptrArray8
, but the interface expectsFFmpeg.AutoGen.byte_ptrArray4
.
Does anyone know how to convert this parameter, so that I can pass it to the interface ? VS complains with the following error message :
https://docs.microsoft.com/en-us/dotnet/csharp/misc/cs1503?f1url=%3FappId%3Droslyn%26k%3Dk(CS1503)

Thanks in advance for any help on this issue.

If multiple channels, merge then take sample length from audio file and save it to s3
18 mai 2017, par khinesterI am using transloadit to extract the audio from a video file, which is then saved to S3.
This works great, but I wanted to know how to :-
check if the file has multiple channels and then squash it inot one as per https://transloadit.com/demos/audio-encoding/merging-multiple-audio-streams/ - do I need to check for this or do i default to use this robot ?
-
extract a small sample from the audio file - and save this as a separate file.
For example, I have a 2h audio file from which I want to take 5% of the length and save this as sample.mp3
In ffmpeg, i can cut :
ffmpeg -ss 0 -t 30 -i original.mp3 sample.mp3
but I am unsure how to chain this workflow, here is what i have thus far :
const opts = {
params: {
notify_url: `${ process.env.SELF }/services/trans/${ jwToken }`,
steps: {
import: {
robot: '/s3/import',
use: ':original',
bucket: process.env.S3_INGEST,
path: ingest.key,
key: process.env.AWS_ID,
secret: process.env.AWS_SECRET,
},
encode: {
robot: '/audio/encode',
use: 'import',
ffmpeg_stack: 'v2.2.3',
preset: 'aac',
ffmpeg: {
ab: '128k',
},
},
export: {
robot: '/s3/store',
use: 'encode',
bucket: s3Export,
path: `${ prefix }/${ token }.m4a`,
headers: {
'Content-Type': 'audio/mp4',
'x-amz-server-side-encryption': 'AES256',
},
key: process.env.AWS_ID,
secret: process.env.AWS_SECRET,
},
},
},
};in the docs, https://transloadit.com/docs/conversion-robots/ i can’t see how to do this ?
any advice is much appreciated.
