Re: [FFmpeg-user] -movflags faststart revisited
Thanx. Are there any flags that will let me playback an unfinished transcode? Reason I am asking is that if my various options in the transcode command did not yield what I like, then I would like to abort the transcode.

Sorry that I was unable to continue on the original thread, because the gmail web interface deletes original message sent to this list by the OP, when the OP deletes the response from the list. So, even though I corrected the usage of the flag, I am still unable to play the output file before ffmpeg finishes the transcoding :( :( As I wrote earlier, that will not work. Ever. You can't play an mp4 file of the file does not contain an moov atom. That atom cannot be written until the encoder is finished, because it contains info that cannot be determined until the encoder is finished encoding. If you want to view the output before the file is closed, your best bet is something like mpeg-ts, or flv. Or one of the segmented formats. -Reuben ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

I retried to use this flag as it was indicated in a previous response by a user. Sorry that I was unable to continue on the original thread, because the gmail web interface deletes original message sent to this list by the OP, when the OP deletes the response from the list. So, even though I corrected the usage of the flag, I am still unable to play the output file before ffmpeg finishes the transcoding :( :( $ ~/bin/ffmpeg.d/ffmpeg -i video_Z11.mp4 -movflags faststart -vb 8000k -ab 384k -s 1920x1080 -y video_Z11-1920x1080.mp4 ffmpeg version 3.2.4-static http://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.1 (Debian 5.4.1-5) 20170205 configuration: --enable-gpl --enable-version3 --enable-static --disable-debug --disable-ffplay --disable-indev=sndio --disable-outdev=sndio --cc=gcc-5 --enable-fontconfig --enable-frei0r --enable-gnutls --enable-gray --enable-libass --enable-libfreetype --enable-libfribidi --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxvid --enable-libzimg libavutil 55. 34.101 / 55. 34.101 libavcodec 57. 64.101 / 57. 64.101 libavformat57. 56.101 / 57. 56.101 libavdevice57. 1.100 / 57. 1.100 libavfilter 6. 65.100 / 6. 65.100 libswscale 4. 2.100 / 4. 2.100 libswresample 2. 3.100 / 2. 3.100 libpostproc54. 1.100 / 54. 1.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'video_Z11.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 creation_time : 2016-11-29T13:42:34.00Z encoder : Lavf56.1.0 Duration: 02:22:55.48, start: 0.00, bitrate: 379 kb/s Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p, 480x360 [SAR 1:1 DAR 4:3], 246 kb/s, 29.95 fps, 29.97 tbr, 90k tbn, 59.91 tbc (default) Metadata: creation_time : 2016-11-29T13:42:34.00Z handler_name: VideoHandler Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 125 kb/s (default) Metadata: creation_time : 2016-11-29T13:42:34.00Z handler_name: SoundHandler [libx264 @ 0x5a3c240] using SAR=3/4 [libx264 @ 0x5a3c240] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 [libx264 @ 0x5a3c240] profile High, level 4.0 [libx264 @ 0x5a3c240] 264 - core 148 r333 90a61ec - H.264/MPEG-4 AVC codec - Copyleft 2003-2017 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 deblock=1:0:0 analyse=0x3:0x113 me=hex subme=7 psy=1 psy_rd=1.00:0.00 mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=3 lookahead_threads=1 sliced_threads=0 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=1 b_bias=0 direct=1 weightb=1 open_gop=0 weightp=2 keyint=250 keyint_min=25 scenecut=40 intra_refresh=0 rc_lookahead=40 rc=abr mbtree=1 bitrate=8000 ratetol=1.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 ip_ratio=1.40 aq=1:1.00 Output #0, mp4, to 'video_Z11-1920x1080.mp4': Metadata: major_brand : isom minor_version : 512 compatible_brands: isomiso2avc1mp41 encoder : Lavf57.56.101 Stream #0:0(und): Video: h264 (libx264) ([33][0][0][0] / 0x0021), yuv420p, 1920x1080 [SAR 3:4 DAR 4:3], q=-1--1, 8000 kb/s, 29.97 fps, 30k tbn, 29.97 tbc (default) Metadata: creation_time : 2016-11-29T13:42:34.00Z handler_name: VideoHandler encoder : Lavc57.64.101 libx264 Side data: cpb: bitrate max/min/avg: 0/0/800 buffer size: 0 vbv_delay: -1 Stream #0:1(und): Audio: aac (LC) ([64][0][0][0] / 0x0040), 44100 Hz, stereo, fltp, 384 kb/s (default) Metadata: creation_time : 2016-11-29T13:42:34.00Z handler_name: SoundHandler encoder : Lavc57.64.101 aac Stream mapping: Stream #0:0 -> #0:0 (h264 (native) -> h264 (libx264)) Stream #0:1 -> #0:1 (aac (native) -> aac (native)) Press [q] to stop, [?] for help ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
