ffmpeg -f image2pipe -vcodec ppm -i - -y -vcodec libx264 -preset medium -crf 22 -pix_fmt yuv420p video.mp4 I wouldn't call this a bug with FFmpeg unless you think the default behavior should be changed to auto-select -pix_fmt yuv420p for RGB24 inputs when encoding with libx264. x264 does technically support RGB, but YUV usually recommended FFmpeg is a multiplatform, open-source library to record, convert and stream video and audio files. Created in 2000, it is a powerful command-line tool that runs on Linux, Windows and Mac operating systems This is useful if your sequence does not start with img001.jpg but is still in a numerical order. The following example will start with img100.jpg : ffmpeg -f image2 -start_number 100 -i img%d.jpg /tmp/a.mpg. If you have large number of pictures to rename, you can use the following command to ease the burden [ppm @ 0x2bdf4f0] [IMGUTILS @ 0x7fff8f08bde0] Picture size 160x0 is invalid Last message repeated 1 times frame= 140 fps= 0 q=0.0 Lsize= 422kB time=5.56 bitrate= 621.9kbits/ FFmpeg can be hooked up with a number of external libraries to add support for more formats. None of them are used by default, their use has to be explicitly requested by passing the appropriate flags to ./configure. 1.1 Alliance for Open Media (AOM) FFmpeg can make use of the AOM library for AV1 decoding and encoding

ffmpeg -r 60 -f image2 -s 1920x1080 -i pic%04d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p test.mp4 where the %04d means that zeros will be padded until the length of the string is 4 i.e 0001 0020 0030 2000 and so on.

After seven years the native FFmpeg AAC encoder has had its experimental flag removed and declared as ready for general use. The encoder is transparent at 128kbps for most samples tested with artifacts only appearing in extreme cases Since we're planning to output PPM files, which are stored in 24-bit RGB, we're going to have to convert our frame from its native format to RGB. ffmpeg will do these conversions for us. For most projects (including ours) we're going to want to convert our initial frame to a specific format. Let's allocate a frame for the converted frame now $ ffmpeg -y -r 60 -f image2pipe -vcodec ppm -i prompt.ppm -vcodec libx264 -preset medium -pix_fmt yuv420p -crf 1 -threads 0 -bf 0 prompt.mp4 and the conversion went through without incident. The setup here, vs the one on my desk at work, is more or less identical in terms of the main machine

  2. The movie making software FFmpeg can read PPM files directly, so this step is optional. However, the (compressed) PNG files are much smaller than the (uncompressed) PPM files, so this step reduces intermediate disk space usage. Once the bitmap files are created, the FFmpeg tool can be used to create movies in any of a wide variety of formats.
  3. With ffmpeg can you convert and multiplex almost every video file. And as it's a command line converter can you batch convert all your files at once with a basic windows/dos script. Like convert all your video files to mp4 with custom ffmpeg commands

10. Enter the conversion command. The conversion command starts with ffmpeg -i and then includes your file's current name and file type as well as whatever you want the converted file name and file type to be. For example, to convert an MP4 video called Kitties into a WAV file called Cats, you would type in ffmpeg -i Kitties.mp4 Cats.wav here When OSX was introduced, it became possible to run Unix command line tools like ffmpeg, mpeg2enc and vcdimager. However, operation in command line mode was time consuming. Some GUIs popped out for each tool from pioneers like Ross, Henry Mason and Jesper Nillson, but still, many apps were required to go through a full encoding and authoring.

Non-compression. Linear pulse-code modulation (LPCM, generally only described as PCM) is the format for uncompressed audio in media files and it is also the standard for CD-DA; note that in computers, LPCM is usually stored in container formats such as WAV, AIFF, or AU, or as raw audio format, although not technically necessary..
