It shows me optical if the values are above 235 or under 16. A numerical way would be much better, of course. But that is another issue.

[FFmpeg-user] deinterlacing SD content
Hi, I have SD TV recordings (mpeg2, ts container) here which I would like to deinterlace and convert to h.265. I'm playing the recording with VLC. When I play the original, the movie looks ok. For the converted movie, I can see the typical horizontal lines for moving objects. Forcing VLC to deinterlace the converted movie leads to a very stuttering image. I guess I must be doing something wrong, but am not sure what it is... command line used: D:\ffmpeg\bin\ffmpeg -i movie.ts -map 0:0 -map 0:1 -map 0:2 -c:a copy -vf yadif=1 -c:v libx265 -preset veryslow -x265-params crf=20 -strict experimental movie.mkv" 2>>movie.log Output: ffmpeg version N-71737-gb410c69 Copyright (c) 2000-2015 the FFmpeg developers built with gcc 4.9.2 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libdcadec --enable-libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --enable-libvidstab --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-lzma --enable-decklink --enable-zlib libavutil 54. 23.101 / 54. 23.101 libavcodec 56. 35.101 / 56. 35.101 libavformat56. 31.100 / 56. 31.100 libavdevice56. 4.100 / 56. 4.100 libavfilter 5. 14.100 / 5. 14.100 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc53. 3.100 / 53. 3.100 [mpegts @ 0459a020] Could not find codec parameters for stream 2 (Unknown: none ([6][0][0][0] / 0x0006)): unknown codec Consider increasing the value for the 'analyzeduration' and 'probesize' options Input #0, mpegts, from 'movie.ts': Duration: 00:42:23.28, start: 89788.048133, bitrate: 3355 kb/s Program 132 Stream #0:0[0x3ff]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), yuv420p(tv), 720x576 [SAR 16:15 DAR 4:3], max. 15000 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc Stream #0:1[0x400](deu): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 192 kb/s Stream #0:2[0x20]: Unknown: none ([6][0][0][0] / 0x0006) x265 [info]: HEVC encoder version 1.6 x265 [info]: build info [Windows][GCC 4.9.2][64 bit] 8bpp x265 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX AVX2 FMA3 LZCNT BMI2 x265 [info]: Main profile, Level-3 (Main tier) x265 [info]: Thread pool created using 8 threads x265 [info]: frame threads / pool features : 3 / wpp(9 rows) x265 [info]: Coding QT: max CU size, min CU size : 64 / 8 x265 [info]: Residual QT: max TU size, max depth : 32 / 3 inter / 3 intra x265 [info]: ME / range / subpel / merge : star / 57 / 4 / 4 x265 [info]: Keyframe min / max / scenecut : 25 / 250 / 40 x265 [info]: Lookahead / bframes / badapt: 40 / 8 / 2 x265 [info]: b-pyramid / weightp / weightb / refs: 1 / 1 / 1 / 5 x265 [info]: Rate Control / AQ-Strength / CUTree : CRF-20.0 / 1.0 / 1 x265 [info]: tools: rect amp rd=6 psy-rd=0.30 rdoq=2 psy-rdoq=1.00 signhide x265 [info]: tools: tmvp b-intra strong-intra-smoothing deblock sao [matroska @ 045a6480] Codec for stream 1 does not use global headers but container format requires global headers Output #0, matroska, to 'movie.mkv': Metadata: encoder : Lavf56.31.100 Stream #0:0: Video: hevc (libx265), yuv420p, 720x576 [SAR 16:15 DAR 4:3], q=2-31, 25 fps, 1k tbn, 25 tbc Metadata: encoder : Lavc56.35.101 libx265 Stream #0:1(deu): Audio: mp2 (P[0][0][0] / 0x0050), 48000 Hz, stereo, 192 kb/s Stream mapping: Stream #0:0 -> #0:0 (mpeg2video (native) -> hevc (libx265)) Stream #0:1 -> #0:1 (copy) Press [q] to stop, [?] for help frame= 56 fps=0.0 q=0.0 size= 10kB time=00:00:01.60 bitrate= 52.2kbits/s frame= 61 fps= 55 q=0.0 size= 19kB time=00:00:01.89 bitrate= 83.9kbits/s frame= 64 fps= 38 q=0.0 size= 45kB time=00:00:02.04 bitrate= 180.9kbits/s frame= 68 fps= 31 q=0.0 size= 59kB time=00:00:02.18 bitrate= 221.6kbits/s frame= 69 fps= 25 q=0.0 size= 68kB time=00:00:02.35 bitrate= 235.4kbits/s frame= 72 fps= 21 q=0.0 size= 95kB time=00:00:02.47 bitrate= 316.4kbits/s frame= 74 fps= 18 q=0.0 size= 119kB time=00:00:02.47 bitrate= 394.6kbits/s frame= 76 fps= 16 q=0.0 size= 147kB time=00:00:02.61 bitrate= 459.5kbits/s frame= 77 fps= 15 q=0.0 size= 149kB time=00:00:02.64 bitrate= 461.8kbits/s frame= 81 fps= 13 q=0.0 size= 183kB time=00:00:02.78 bitrate= 538.9kbits/s frame= 85 fps= 13 q=0.0 size=

[FFmpeg-user] Merge 2 Video + Audio files in a single file side by side.
Hi... I need some help :) I need to merge 2 video files along with their audio in single file side by side. I am able to merge 2 video files in single file but it using audio of first video file only, where as i need to merge audio of second file as well. below is command i am using to do that. `ffmpeg.exe -i input1.webm -vf "[in] scale=iw/2:ih/2, pad=2*iw:ih [left]; movie=input2.webm, scale=iw/2:ih/2 [right]; [left][right] overlay=main _w/2:0 [out]" -b:v 768k ouput.webm` i have tried various way with `amerge` but no success. As I am new to FFMpeg, i am not sure how can i achieve this. Please please help me on this.

[FFmpeg-user] Capture H.264 stream from Logitech C930e (C930) webcam
I am trying to capture the camera-encoded H.264 video stream from a Logitech C930e webcam. It seems that there is support for this in the UVC driver and I understand that guvcview supports this camera: http://sourceforge.net/p/linux-uvc/mailman/message/33405777/ But, I am operating in a command line environment. I need to capture the H.264 stream from the camera, write it to a file, and possibly retransmit it. I would like to use ffmpeg and ffserver. Ideally I'd like this to work on a Raspberry Pi, but am happy to use whatever hardware and OS makes this work. How can I do this using ffmpeg? ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user

Please find below 2 links with video samples. I created the original at 24 fps from scratch and then I used Apple Cinema tools to create the conformed 25 fps version. As you can see, the 25 fps version has the same exact frames but shorter duration. That's what I would like to achieve with ffmpeg. Additionally the sample rate of the conformed version has been pulled up to 50.000 kHz (=48.000x(25/24)) to keep audio in sync, but I can assure no transcoding is made in this operation, it takes fractions of a second to modify the header of the file. I believe this is a feature of the Quicktime structure to be able to modify these values in the header, btw. the operation of conforming in Cinema Tools is only possible with intra-frame codecs like Prores. Thanks for your insight wether this could be possible to do with ffmpeg.

Re: [FFmpeg-user] How to silently ignore inexistent inputs
I’ve tried to use this approach with ffprobe to check the aliveness of streams.
Unfortunately, the streams unpublishing are quite often, so the time gap is
rather big and often I still getting the same error…
Anyway, thank you for your response :)

You can use -flags +bitexact to avoid writing the muxer library name to the output file, note that this makes future bug autodetection impossible and is therefore strongly discouraged!

Re: [FFmpeg-user] How to silently ignore inexistent inputs
On startup, run a quick 'is alive' detection call ("ffmpeg -i rtmp://
server.com/stream X") through all the streams
that u have, then build your cmd line only for those that that are alive.
