I want to compress a film which has dvdrip and brrip with mp4 and h.264 codecs.
ffmpeg -i video.avi -vcodec libx264 -crf 25 -acodec libfaac -vpre slower \
-acodec copy video.mp4
error message
Invalid option or argument: 'directpred=3', parsed as 'directpred' = '3'

I tried to stream an mp3 file to a Telegram RTMP live using the following command:
ffmpeg -re -i 1.mp3 -c copy -f mp3 rtmps://dc4-1.rtmp.t.me/s/145158:AtyF3rrME2nHEkqGA
But I couldn't hear any sound in the stream.
You should specify the codecs explicitly.
The following is the simplest working command:
ffmpeg -i your_input -c:v libx264 -c:a aac -f flv rtmps://dcx-y.rtmp.t.me/s/YOUR_KEY
Here is a more advanced example from #tgbeta:
ffmpeg -stream_loop -1 -re -i your_input -c:v libx264 -preset veryfast -b:v 3500k -maxrate 3500k -bufsize 7000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmps://dcx-y.rtmp.t.me/s/YOUR_KEY
Change -f mp3 by -f flv.
Example:
ffmpeg -re -i 1.mp3 -c:a copy -f flv rtmps://dc4-1.rtmp.t.me/s/145158:AtyF3rrME2nHEkqGA
I´m working on a webcam-project. It is for generating timelapse videos of sunset/sundown.
I´m using a raspberrypi to generate them with gphoto2 + DSLR.
At the end of the day the images should get to an video, with audio and an overlay logo.
And it should be scaled to 1920 pixel.
I got a nice solution an it worked.
Producing the timelapse video an scale it:
ffmpeg -y -framerate 25 -start_number 0000001 -i /var/www/html/webcam/2020-01-05_bilder/%7d.jpg -vf scale=1920:-1 -pix_fmt yuv420p /var/www/html/webcam/2020-01-05-tag-output-1920.mp4
Taking the output of (1) and add an overlay-logo, add audio
ffmpeg -y -i '/var/www/html/webcam/2020-01-05-tag-output-1920.mp4'
-i '/var/www/html/webcam-scripts/graphics/logo.png'
-i '/var/www/html/webcam-scripts/sounds/chill_time_5.mp3'
-shortest -filter_complex '[1][0]scale2ref=h=ow/mdar:w=iw/6[#A logo][liebfrauen]; [#A logo]format=argb,colorchannelmixer=aa=0.95[#B logo transparent]; [liebfrauen][#B logo transparent] overlay=(main_w-w)-(main_w*0.05):(main_h-h)-(main_h*0.01)'
-c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a aac -strict -2
'/var/www/html/webcam/2020-01-05-tag-1920.mp4
I tried to combine both actions, but I get an error:
ffmpeg -y -framerate 25 -start_number 0000001 -i '/var/www/html/webcam/2020-01-05_bilder/%7d.jpg' -vf scale=1920:-1 -pix_fmt yuv420p -i '/var/www/html/webcam-scripts/graphics/logo.png' -i '/var/www/html/webcam-scripts/sounds/chill_time_5.mp3' -shortest -filter_complex '[1][0]scale2ref=h=ow/mdar:w=iw/6[#A logo][liebfrauen]; [#A logo]format=argb,colorchannelmixer=aa=0.95[#B logo transparent]; [liebfrauen][#B logo transparent] overlay=(main_w-w)-(main_w*0.05):(main_h-h)-(main_h*0.01)' -c:v libx264 -crf 18 -preset slow -pix_fmt yuv420p -c:a aac -strict -2 '/var/www/html/webcam/2020-01-05-tag-1920.mp4'
Error: Filtergraph 'scale=720:-1' was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph.
-vf/-af/-filter and -filter_complex cannot be used together for the same stream.
Isn`t it possible to combine these inputs and scale it? Or ... Where is my misunderstanding?
Don't mix -vf and -filter_complex. Do all filtering in one filtergraph.
ffmpeg -y -framerate 25 -i '/var/www/html/webcam/2020-01-05_bilder/%7d.jpg' -i '/var/www/html/webcam-scripts/graphics/logo.png' -i '/var/www/html/webcam-scripts/sounds/chill_time_5.mp3' -filter_complex '[0]scale=1920:-2[v0];[1][v0]scale2ref=h=ow/mdar:w=iw/6[#A logo][liebfrauen]; [#A logo]format=argb,colorchannelmixer=aa=0.95[#B logo transparent]; [liebfrauen][#B logo transparent] overlay=(main_w-w)-(main_w*0.05):(main_h-h)-(main_h*0.01),format=yuv420p' -c:v libx264 -crf 18 -preset slow -c:a aac -shortest '/var/www/html/webcam/2020-01-05-tag-1920.mp4'
No need for -strict -2. It does nothing for modern ffmpeg.
I replaced -pix_fmt yuv420p with format=yuv420p so it is more organized.
-start_number 0000001 is not needed because 1 is the default.
I have this command to add watermark to an mp4
ffmpeg -i junai-blvaz.mp4 -i evercam-logo-white.png -filter_complex "[1]scale=iw/2:-1[wm];[0][wm]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-10" -codec:a copy output.mp4
But I am creating the video using
ffmpeg -r 6 -i /tmp/%d.jpg -c:v h264_nvenc -r 6 -preset slow -bufsize 1000k -pix_fmt yuv420p -y junai-blvaz.mp4
Is there any way to merge this command of adding watermark
-i evercam-logo-white.png -filter_complex '[1]scale=iw/2:-1[wm];[0][wm]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-10'
to the very first command through which mp4 video has been created?
Combine the two commands:
ffmpeg -y -framerate 6 -i /tmp/%d.jpg -i evercam-logo-white.png -filter_complex "[1]scale=iw/2:-1[wm];[0][wm]overlay=x=main_w-overlay_w-10:y=main_h-overlay_h-10,format=yuv420p" -c:v h264_nvenc -preset slow -bufsize 1000k junai-blvaz.mp4
I have 300 images and i wants to generate video from these images.
i am new to FFMPEG so now i am using two commands to generate video from images.
Command to generate video from images which also add Logo on video
ffmpeg -framerate 24 -i img_%d.jpg -i logo.png -filter_complex \
"[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" \
-vcodec libx264 -crf 25 -pix_fmt yuv420p test_video.mp4
After using above command i am getting the video to add audio to this video i am using below command
ffmpeg -i test_video.mp4 -i inputfile.mp3 -c:v libx264 -c:a libvorbis -shortest final_video.mp4
which generates video and i am getting below message
MPEG-4 AAC decoder is required to play the file
Help to combine this both command. if possible can we add sound without any decoder required
Log for command 1 https://drive.google.com/file/d/1zS7gvrPy69VK_MkyE4127FpX2kEziJHq/view?usp=sharing
and Log command 2 https://drive.google.com/file/d/1rHqVGzj7f003aWP6eISiyUjsES8_EWuw/view?usp=sharing
Try next command:
ffmpeg -framerate 24 -i img_%d.jpg -i logo.png -i inputfile.mp3 -filter_complex \
"[0:v][1:v] overlay=25:25:enable='between(t,0,20)'" \
-vcodec libx264 -crf 25 -map 2:a -c:a copy -pix_fmt yuv420p -shortest test_video.mp4
-map 2:a is needed to skip image in case if there is cover image in track.
With -c:a copy track will not be re-encoded, so you will have mp3 inside of your video file.
I have created video with multiple images and single music file. It's working fine
ffmpeg -y -framerate 1/5 -start_number 1 -i /<<dir path>>/photo3-%04d.jpg -i /<<dir path>>/music3-000.mp3 -c:v libx264 -r 30 -pix_fmt yuv420p -c:a aac -strict experimental -shortest /<<dir path>>/video/output.mp4;
But when I tried with multiple music files it throws and error in terminal.
Command:
ffmpeg -y -framerate 1/5 -start_number 1 -i /<<dir path>>/photo3-%04d.jpg -i /<<dir path>>/music3-%03d.mp3 -c:v libx264 -r 30 -pix_fmt yuv420p -c:a aac -strict experimental -shortest /<<dir path>>/video/output.mp4;
Error:
/<<dir path>>/music3-%03d.mp3: No such file or directory
There's no audio sequence demuxer. To combine multiple audio files in your command, you'll have to use the concat demuxer.
First, create a text file with the list of files
file 'music3-000.mp3'
file 'music3-001.mp3'
file 'music3-002.mp3'
...
Then run
ffmpeg -y -framerate 1/5 -start_number 1 -i /<<dir path>>/photo3-%04d.jpg \
-f concat -i list.txt \
-c:v libx264 -r 30 -pix_fmt yuv420p -c:a aac -strict experimental
-shortest /<<dir path>>/video/output.mp4
