If it is, no need to re-encode, just change the container to mp4įfmpeg -i filename.flv -c copy -copyts output.mp4
Check if the flv audio and video stream is supported by your device. So, for my records, before all these commands get lost in history (man history):įfmpeg -i inputfilename.ext -vcodec copy outfilename.extįfmpeg -i inputfilename.ext -acodec copy outfilename.extĬonvert aac audio do mp3 (-ar freq in Hz -ab bitrate in bit/s), ex: convert at 44100Hz, 128Kbitsįfmpeg -i filename.aac -ar 44100 -ab 131072 audio.mp3Ĭonvert aac audio do mp3 with volume adjust, good if sound is too high/low, -vol switch (256=normal), ex: 512 two times louder, 128 half soundįfmpeg -i filename.aac -ar 44100 -ab 131072 -vol 512 audio.mp3Ĭonvert raw avi to M$ compatible vanilla installation (no codecs) of Windows Media Player (-b switch for bitrate quality), example at 10Mb/s (good quality)įfmpeg -i filename.avi -vcodec msmpeg4v2 -b 10000000 filename.aviĬonvert raw avi to M$ compatible vanilla installation (no codecs) of Windows Media Player with frame rate adjust, example to 24 frames per secondįfmpeg -i filename.avi -vcodec msmpeg4v2 -b 10000000 -r 25 filename.aviĬonvert raw avi to M$ wmv at 24 fps with the same quality settings of the original fileįfmpeg -i filename.avi -vcodec wmv1 -sameq -r 25 lfilename.wmvĬonvert mp4 to avi, with the same quality settingsįfmpeg -i filename.mp4 -sameq filename.aviĬonvert flv to mp4, keeping the same quality. Then i remember to try in my Linux box ffmpeg, this is a pure command line utilty (no GUI in the middle, but there are some out there), and everything worked out rather good. first i tried some GUIs in M$ Windows, spent more time than i wanted in installation, testing, de-installing of messy software, and always the overall final results where nothing short of horrible. Convertions of formats/containers, codecs, sound adjustments, the works….
The last weeks, due to some stars alignment i had to do a lot of work with video files.
