how to choose ffmpeg video mp3 audio version id ?
7 juin 2013, par UlteriorI am having issues on ffmpeg encoded video files audio tracks. My encoded video contains ID for audio track as extracted from mediainfo :
I use CODEC_ID_MP3 in guess_format "mov" container for quicktime
Audio
ID : 2
Format : MPEG Audio
Format version : Version 2
Format profile : Layer 3
Codec ID : .mp3
Duration : 2s 916ms
Bit rate mode : Constant
Bit rate : 128 Kbps
Channel(s) : 1 channel
Sampling rate : 16.0 KHz
Compression mode : Lossy
Stream size : 45.3 KiB (2%)
Language : EnglishThis is not recognized on a vanilla codecless installation of windows 7, only played by k-lite codec libmad
I have noticed, that another test file contains similar mp3 track and is played by media player OK :
Audio
ID : 2
Format : MPEG Audio
Format version : Version 1
Format profile : Layer 3
Mode : Joint stereo
Mode extension : MS Stereo
Codec ID : 6B
Duration : 1mn 9s
Bit rate mode : Constant
Bit rate : 320 Kbps
Channel(s) : 2 channels
Sampling rate : 44.1 KHz
Compression mode : Lossy
Stream size : 2.67 MiB (38%)
Writing library : LAME3.98The difference I noticed is in Format version number and Codec ID, which is Version 2 from ffmpeg output - I couldnt locate this version setting in ffmpeg source files, so my question is - is there a way to influence this format version identificator and set the codec id as in above playable video ?

PHP and FFMPEG Remove Code in Video [on hold]
6 janvier 2015, par user580950I have set of videos where i need to remove the code ( check below screen grab as an example ), you can see the code in RED .NOt sure if its possible to do it using PHP & ffmpeg or similar to detect a black box or hash key or serial no and blur out.
It must be able to use mpeg-ts file input and output with mpeg-ts.
Detection must be done and blurring must start 5 (configurable) seconds before the black box appears, this means we have to buffer the video and blur out the position where it will appear before it does.

Realtime recording in multiple encodings python
3 janvier 2015, par eripI am working on a project that requires audio recording and am using python. I would like to use a start button to begin recording and a stop button to stop it. Additionally, I’d like to support multiple filetypes like .wav, .mp3, .aiff.
As far as I know, there doesn’t exist something that can do this "in one go", meaning I could record something as a .wav and then post-process the file to encode it in different formats using ffmpeg or a similar library.
This presents a small problem because my project is web-based, so I would have to save the .wav and then save the .*.
Does anyone know of another solution to my problem ?
Thanks, erip
