FFmpeg does convert the file but it continually repeats mp4 0xe28070pts has no value. I HAVE THIS PROBLEM, HOW I CAN FIX IT BossBoss1271 - Either youre not in the same so directory as video.mkv, or a file with that name doesnt exist.Before you run the ffmpeg command, run ls -l to make sure the file is there. So, when I try using ffmpeg, at the command prompt (XP SP3), I am typing in (where m2.flv is the original): ffmpeg -i m2.flv -vcodec copy -acodec copy m2.mp4. ffmpeg -i 'video.mkv' -c copy 'video-mp4' video.mkv: No such file or directory. Here is the command I am running: /opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt. The audio seems ok but the video seems slow and therefore out of sync with the audio. I’m aware that ffmpeg can do this for me but I do not understand this program. I am trying to convert a flv video to mp4 using a264, but the result video has a out of sync audio/video. AVIDemux allows me to remux any audio format to an MP4 container but I can not batch with it. ![]() ![]() Many programs I found do not allow AAC to be passthtough. Most are 2 channel audio but they are a mix of AAC and AC3. MetaFox will not reconvert any video/audio but only remux it to a mkv file container so you will not lose any video/audio quality. I also have ffdshow tryouts (latest) installed with it set to decode h.264. I have hundreds of MKV files I need to remux to MP4. MetaFox converts/remuxes HEVC, AVI, MOV, MP4, MPG, FLV, RMVB, etc. transcode it via ffmpeg piped through raspivid to an rtmp server as flv video. ![]() Tagged date : UTC 06:22:44 its simple to re-encode these with handbrake using the same format for video and audio and they will play on anything however i am wondering if there is easy way around this problem using other software that will make the mp4's compatible without a full re-encode?Įncoding settings : cabac=1 / ref=3 / deblock=1:0:0 / analyse=0x3:0x113 / me=umh / subme=6 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / constrained_intra=0 / bframes=2 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=2 / weightb=1 / open_gop=0 / weightp=0 / keyint=30 / keyint_min=16 / scenecut=0 / intra_refresh=0 / rc_lookahead=30 / rc=abr / mbtree=1 / bitrate=6800 / ratetol=1.0 / qcomp=0.60 / qpmin=1 / qpmax=31 / qpstep=4 / ip_ratio=1.41 / aq=1:1.
