What is Encoding SW Lavf58.29.100?

[Selur]

ffmpeg or similar software bsed on libavformat,.....

[Anonymous543]

Now what is libavformat ,does it sourcecode of ffmpeg?

[Selur]

libav is a part of the FFmpeg project, and is used in the ffmpeg tool.

Got it ,one more question can we change
Name of lavf58.29.100 to anything?
By editing metadata of video?

[Selur]

mkvtoolnix header editor might be able to overwrite the field, but not totally sure. (never tried it, my guess is that the field is the 'writing application' field which should be editable)
If you use another container another tool will be needed.

Ohh

You can change it with a hex editor.

General
Complete name                            : C:\Purple Pigs\00001 - Copy (2).mp4.avs.mp4
Format                                   : MPEG-4
Format profile                           : Base Media
Codec ID                                 : isom (isom/iso2/avc1/mp41)
File size                                : 49.2 MiB
Duration                                 : 32 s 334 ms
Overall bit rate                         : 12.8 Mb/s
Writing application                      : I changed it!

But you're limited to the same number of characters when using a hex editor.

I have to open video in hex editor then search for Lavf58.29.100, Then replace it to custom name right?

[jagabo]

Yes.

It works fine!!
Thank youu @jagabo

[Anonymous543]

Btw if we add so much meta data like
artist name
Movie name
Movie year
Actress name
Song lyrics etc then will it increases file size?

[Anonymous543]

??

[pandy]

yes, marginally - such data are optional and from decoder perspective not required to decode content.

[Anonymous543]

Ohh

[jagabo]

That type of metadata is plain text. It's very small compared to the audio and video streams in an A/V file. It may account for few hundred bytes in a GB byte A/V file or a MB mp3 file. It's not worth worrying about. Some other types of metadata, like thumbnails and poster art (images), are bigger but also usually not worth worrying about.
