Doesn't -c enable encoding or decoding (as well as the certainly trivial 'copy') of a stream, depending upon the choice and the existing stream's codec?

Yes, I know it cannot be played with most of th players, I need to see the size of the RAW video and make some compression on it for our further analysis. Could you please help me on the missing parameters to generate the RAW video? I did some tests and came to the conclusion that it's impossible to import a group of numbered raw images. It's possible to import a single raw image. It's possible to import a group of numbered images (JPG, PNG, TIF...) But it's not possible to import a numbered group of raw images. (To the experts: Please correct me if I'm wrong). Anyway it's a bad idea to save the images in raw format. You should use PNG images, which have a lossless compression, and 16-bit depth is possible. I recommend that you convert your images to PNG, and then things become much easier. Here is a (Windows) batch file with a few examples: rem Make 30 PNG images (48-bit per pixel): ffmpeg -f lavfi -i testsrc2=s=320x200,format=rgb48 -frames 30 -f image2 -y image-%%03d.png rem Convert these 30 images to a raw video (this conversion is lossless): ffmpeg -i image-%%03d.png -s 320x200 -pixel_format rgb48 -f rawvideo -c:v rawvideo -y video.raw rem The size of the raw video is exactly 320 * 200 * 2 * 3 * 30 = 1152 Bytes rem Convert the first frame from the raw video to a PNG image (48-bit per pixel): ffmpeg -video_size 320x200 -pixel_format rgb48 -f rawvideo -i video.raw -frames 1 -y image.png rem Convert the raw video to a (almost lossless) MP4 video: ffmpeg -video_size 320x200 -pixel_format rgb48 -f rawvideo -framerate 30 -i video.raw -crf 0 -y video.mp4 pause I have a question to the experts. The above example works fine with pixel format rgb48, but with pixel formats gray16 or gray10le the MP4 output looks wrong. I don't yet understand why.

[FFmpeg-user] encode to RAW video
Hello Team, I have managed to convert raw Images files to .mp4 video, I need to encode to a RAW video instead, could you please let me know the command for this? RAW Image file is, resolution - 1600x1300 fps-30 bit depth-16bit Thanks and Regards, Naveen B. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
