I need to encode an specific mp4, i have been trying with the ffmpeg, but i couldnt make it, if you could help me with these would be great.
The encoding requirements are these:
Main profile Level 3.0
Set CABAC for Main profile
Constant bit rate encoding
1.5-2.0 Mb´s resolution
Closed GOP must be set
GOP size shall be equal to 1/2 second, with the following exceptions:
-Utilizing GOP size less than 1/2 second is acceptable and shall be used for scene change detection.
Every I-frame must be in IDR- IDR Frecuency shall be set to 1
Streaming format is required e.g SPS and other secuence headers shall be repeated throughout the stream to facilitate fast decoder synchronization during random acces.
B-Frames shall be used when main profile is chosen
No referenced B-frames
Number of B-Frames shall be set to 2 or 3
Number of referenced frames shall be set to 2
Encode without wight prediction
Number of slices shall be set to 1,2 or 4
