High pitched audio or no audio at all when converting AVI video to MP4 with FFmpeg [closed]
15 août 2023, par Karen SI'm pretty new to FFmpeg and I'm having trouble converting a video from AVI format to MP4. I'm trying to convert pcm_s16le to aac. No matter what audio stream I use, the resulting audio in the MP4 file is either very high pitched and choppy (stream 1) or the audio stream is silent (stream 2).


The AVI video has two audio streams :


Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s
Stream #0:2: Audio: pcm_s16le, 32000 Hz, stereo, s16, 1024 kb/s



In VLC Media Player the video plays fine and it uses the second audio stream.


When I run
ffmpeg -i input.avi -vcodec libx264 -crf 27 output.mp4
in my terminal, the output audio in the MP4 file is very high pitched and choppy in VLC.
This is the codec information for the audio stream in VLC after the conversion :

Codec: MPEG AAC Audio (mp4a)
Type: Audio
Channels: Stereo
Sample rate: 48000 Hz
Bits per sample: 32



When I specify the audio stream and codec the resulting video is silent.


ffmpeg -i input.avi -map 0:v:0 -vcodec libx264 -crf 29 -map 0:a:1 -acodec aac output.mp4



This is the terminal output from FFmpeg :


FILEPATH -i "input.avi" -map 0:v:0 -vcodec libx264 -crf 29 -map 0:a:1 -acodec aac "output.mp4"

FFMPEG on AWS Lambda Only outputs half a second of video when converting video from mobile safari
18 août 2023, par user1825257I am running FFMPEG on AWS Lambda using nodejs and fluent-ffmpeg. I am able to convert videos recorded on most devices / browsers, but when I attempt to convert videos recorded on Mobile Safari, the length of the output video is 1/2 a second regardless of the input length.


My Typescript code is :


import * as ffmpeg from 'fluent-ffmpeg';
 public static StandardizeVideoFormat(
 inputSignedUrl: string,
 filename: string,
 ): Promise<string> {
 const localFilePath = `/tmp/${Date.now()}_${filename}.mp4`;
 
 return new Promise((resolve, reject) => {
 ffmpeg(inputSignedUrl)
 .outputOptions([
 '-crf',
 '18',
 '-vcodec',
 'libx264',
 '-codec:a',
 'aac',
 '-preset',
 'medium',
 ])
 .output(localFilePath)
 .on('start', function (commandLine) {
 console.log('Spawned Ffmpeg with command: ' + commandLine);
 })
 .on('error', function (err) {
 reject(err);
 })
 .on('progress', function (progress) {
 console.log('progress', progress);
 })
 .on('end', function () {
 resolve(localFilePath);
 })
 .run();
 });
 }
</string>
