• ONLY AUDIO

1.1 Режим ONLY AUDIO

Key	Description	Value
-asrc	Audio source. The absolute file path to which you want to apply effects.	/path/to/source/file.wav
-d	Duration. Create silent file with duration of N seconds.	60
-se	Sound effect. The absolute file paths to sound effects you want to apply.	/sound_efects/ahem_x.wav /sound_efects/bee.wav
-t	Time line. Time in milliseconds when to apply the effect. If adding tag 'L' effect will be loops.	1000 or 1000L
-out	Output. The absolute file path where you want to save mixed audio file.	/path/to/output/file.wav

Impotant:

1. You can choose only -asrc or -d key.
   
2. Number of effects and time stamps in time line should be the same.
   

Example 1 - Mix 3 sound effects with source file

java -jar mixtool.jar -asrc /home/user/source.wav \
-se /sound_efects/ahem_x.wav \
/sound_efects/ahem_x.wav \
/sound_efects/ahem_x.wav \
-t 0 5000L 18000 \
-out /home/ygrigortsevich/Documents/SpilnaSprava/ffmpeg/output/filename.wav

What command do:

1. Audio source file is /home/user/source.wav
   
2. Uses three /sound_efects/ahem_x.wav effect.
   
3. Effects applies to 0, 5, 18 seconds. On the fifth second effect repeats.
   
4. Mixed file saved in /home/ygrigortsevich/Documents/SpilnaSprava/ffmpeg/output/filename.wav
   

Example 2 - Mix 3 sound effects with silent file.

java -jar mixtool.jar -d 60 \
-se /sound_efects/ahem_x.wav \
/sound_efects/ahem_x.wav \
/sound_efects/ahem_x.wav \
-t 0 5000L 18000 \
-out /home/ygrigortsevich/Documents/SpilnaSprava/ffmpeg/output/filename.wav

What command do:

1. Create silent audio file with duration of 60 seconds
   
2. Uses three /sound_efects/ahem_x.wav effect.
   
3. Effects applies to 0, 5, 18 seconds. On the fifth second effect repeats.
   
4. Mixed file saved in /home/ygrigortsevich/Documents/SpilnaSprava/ffmpeg/output/filename.wav
   

1.2 Режим ONLY VIDEO

Key	Description	Value
-fm	Frame mask.	/create_video/frame_%06d.png
-CBR	Constant bitrate.	2000k
-ABR	Average bitrate.	200k
-VBR	Variable bitrate.	100k 300k
-fps	Framerate.	24
-out	Output. The absolute file path where you want to save mixed video file.	/path/to/output/file.mp4

Impotant:

1. You can choose only -CBR or -ABR or -VBRkey.
   

Example 1 - Create only video.

java -jar mixtool \
-fm /create_video/frame_%06d.png \
-ABR 1000k \
-fps 24 \
-out /SpilnaSprava/mixtool/output/ideaVideoAndAudio.mp4

What command do:

1. Video will created from images with mask frame_%06d.png that located in folder create_video.
   
2. Set average bitrate to 1000k.
   
3. Set framerate to 24 frames per second.
   
4. Mixed file saved in /SpilnaSprava/mixtool/output/ideaVideoAndAudio.mp4

-se /sound_efects/car_x.wav \
/sound_efects/ahem_x.wav \
/sound_efects/applause_y.wav \
-t 0 5000L 10000 \
-fm /create_video/frame_%06d.png \
-ABR 1000k \

3. Effects applies to 0, 5, 10 seconds. On the fifth second effect repeats.
   
4. Video will created from images with mask frame_%06d.png that located in folder create_video.
   
5. Set average bitrate to 1000k.
   
6. Set framerate to 24 frames per second.
   
7. Mixed file saved in /SpilnaSprava/mixtool/output/ideaVideoAndAudio.mp4
