#Same with raspberry Pi special encoder (omx - which seems not to be only about Raspberry Pi), without and with target bitrate specification.įfmpeg -f v4l2 -video_size 1280x800 -i /dev/video0 -codec:v h264_omx output-1280x800-h264.mkvįfmpeg -f v4l2 -video_size 1280x800 -i /dev/video0 -codec:v h264_omx -b:v 2048k output-1280x800-h264-bitrate2048k.mkvįfmpeg -i inputFile.avi -codec:v h264_omx outputFile-1280x800-h264.mkvįfmpeg -i inputFile.avi -codec:v h264_omx -b:v 2048k outputFile-1280x800-h264-bitrate2048k. Instant density and quality boost for H.264 encoding and decoding. For the same starwars.mp4 video above, merely 4 seconds are needed to make H264 converted to HEVC. It provides ease for the user, download any video from youtube with simplicity.

The tubedown uses the youtube-dl software as the download standard.

Then tap RUN icon, you'll get a HEVC codec MP4 video from H264 at the drop of a hat. Graphical youtube-dl download mp4 (Python 3). Click on Browse to specify the output folder path. Value of 0 is lossless compression while 51 (for 8-bit samples) or 63 (10-bit). Step 4: Start converting H264 to HEVC/H265. #Standards encoders (not for Raspberry Pi unless you are not hurry)įfmpeg -f v4l2 -video_size 1280x800 -i /dev/video0 -codec:v libx264 output-x264.mkvįfmpeg -f v4l2 -video_size 1280x800 -i /dev/video0 -codec:v libx265 output-x265.mkv Default value: 23 Constant rate factor that affects the quality of output stream. because ffmpeg can do many options which gui encoders does not includes.
I've done encodings with MeGUI, Handbrake, AVIDemux, VirtualDub, ffmpeg, each gave the same video quality - unless you use some special Avisynth scripts. #Doing a raw "capture and place to file" with input resolution specified (still using mux depending on file extension)įfmpeg -f v4l2 -video_size 1280x800 -i /dev/video0 -codec copy output.avi Using ffmpeg won't you give any extra quality. #Listing available formats and resolutions for the capture input :įfmpeg -f v4l2 -list_formats all -i /dev/video0 Code: Select all #Listing available ffmpeg codecs (encoding and decoding)
