This command will of course work:
avconv -i input.mpg -c:v libx264 -s 852x480 -c:a libfaac output.mp4
But that encodes the mpg into a file with these audio settings:
{
"index": 1,
"codec_name": "mp2",
"codec_long_name": "MP2 (MPEG audio layer 2)",
"codec_type": "audio",
"codec_time_base": "1/48000",
"codec_tag_string": "mp4a",
"codec_tag": "0x6134706d",
"sample_fmt": "s16",
"sample_rate": "48000",
"channels": 2,
"bits_per_sample": 0,
"r_frame_rate": "0/0",
"avg_frame_rate": "0/0",
"time_base": "1/48000",
"start_time": "0.000000",
"duration": "60.000000",
"nb_frames": "2500",
"tags": {
"language": "und",
"handler_name": ""
}
}
This is what I need:
Resolution: 480p
Ratio: 1.78
Audio: 2 channel AAC
Video Bitrates: 600 / 800 / 1200 / 2000
Audio Bitrates: 96
Codec: H.264 - High
I tried:
avconv -i input.mpg -c:v libx264 -s 852x480 -c:a libfaac output.mp4
But I get error:
Unknown encoder 'libfaac'
Even after I installed libfaac-dev like this:
sudo apt-get install libfaac-dev
ffmpeg(avconv) by default is not built with faac. So, if you did sudo apt-get install avconv, then may not have faac. This can be checked by running ffmpeg -formats , also in the configuration check for --enable-libfaac. To fix it, you will have re-install ffmpeg by adding --enable-libfaac in the ./config step. I follow this guide to build ffmpeg: https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide
