[FFmpeg-user] Problem building with libx265
Hi,
This used to build for me OK but for some reason it no longer builds with
./configure --enable-libx265
I am using latest git pull from today from both repos but I think this may
be specific to my machine for reasons I can't work out. So if anyone has
pointers please let me know? Details below

[FFmpeg-user] sequence with alpha over a still renders alpha incorrectly
I'm trying to put a png sequence with an embeded alpha over a still image with burned in timecode. The following has been had from everything I see on the web (with the exception of using -shortest that never worked). This renders, but the alpha channel renders in a strange banded sort of way.

[FFmpeg-user] Error and understanding issue: using ffmpeg to real time publish FLV file to Red5 and real time download FLV from Red5
Hello! I am new to ffmpeg, and trying to understand how to use it publish a live stream to a server, and how to record a live stream from a server. After reading online tutorials and visiting few forums, I got a brief overview of how to get it done. But, I think my understanding is not fully correct. Also, the commands I am running, are giving errors. Below I have listed down what I am trying to do, how I am doing it and why. OS: Windows 8, RTMP Server: Red5, Video File format: FLV, I want to: Read/Write FLV files from and to Red5 by live streaming. 1. To publish FLV file from local I am using this command at Command Line: ffmpeg -re -i input.flv -acodec copy -vcodec copy -f flv rtmp://ocalhost/oflaDemo/streams My understanding: This command will upload input.flv to the server location C:\Program Files\red5\webapps\oflaDemo\streams. So, after the command is done running, I expect in this server location a new file input.flv will be created. Is this correct? When I am running this command I am getting the following error and no file is getting created on the server side: [flv @ 03c6a660] Failed to update header with correct duration. [flv @ 03c6a660] Failed to update header with correct filesize. frame= 1567 fps= 24 q=-1.0 Lsize=3064kB time=00:01:05.43 bitrate= 383.6kbits /s video:2232kB audio:767kB subtitle:0kB other streams:0kB global headers:0kB muxin g overhead: 2.183349% Can you help me understand what I am doing wrong? What should be correct command in this case to achieve what I want? 2. Now, I am using the following command to livestream read a FLV file from the server into my local: ffmpeg -re -i rtmp://localhost/oflaDemo/streams/hobbit_vp6.flv -c copy dump.flv My understanding: File hobbit_vp6.flv will be downloaded into my local directory and will get saved as dump.flv. And this will be live streaming. This will be like, recording a video stream from the server. Is this correct? When I am running this command I am getting the following error and no file is getting created on the local: Closing connection: NetStream.Play.StreamNotFound rtmp://localhost/oflaDemo/streams/hobbit_vp6.flv: Unknown error occurred Can you help me understand what I am doing wrong? What should be correct command in this case to achieve what I want? Note: I was not aware of this mailing list before. Hence, have posted this question in stackoverflow as well: http://stackoverflow.com/questions/25567675/error-and-understanding-issue-using-ffmpeg-to-real-time-publish-flv-file-to-red Thanks, Kajari ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user

Ok, that sample is "30" fps progressive. (I am going to use 30 for 29.97=3/1001.) It has 30 complete video frames per second. If you want to reduce it 25 fps You have two choices. 1) Play the same frames slower. You can certainly do that. Putting "-r 25" in the input command will do that. (You will need to adjust the audio too.) However, this will result in slow motion. (clip takes 24 seconds after the conversion.) If it is mostly city shots, this might be fine, but the people walking are noticeably slowed. 2) Throw out information. The problem you have here is that you have six frames ABCDEF when you want five VWXYZ. So if you just chuck one frame F, you will get the judder you don't want. This is what just a "fps=25" filter will do. If you are ok with interlacing, you could split the frames into fields AaBbCcDdEeFf and then throw out every 6th field, to get AaBbCDdEeF. However when you put these back into frames (if you are displaying on a progressive display, you would get Aa, Bb, CD, DE, eF, Those last three interlaced frames might be noticeable. I've never done this sort of thing, but I think "-vf fps=50,interlace" should do it. This would change the judder to more smaller jumps but it might not be what you want. It will also make the video interlaced. 3) Magically turn the 6 frames of progressive video into 5 frames of progressive video showing the same scene evenly spaced out. Requires Magic(tm). -Nick Robbins ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
Re: [FFmpeg-user] How to change video fps from 29.970 to 25?
Ok, here it is: Sample 29.970 fps file which I want to convert to 25fps: http://artnmedia.pl/damian/fps/sample-29.970fps.mp4 My first step is to convert that file to 23.976 fps. I am trying to do this with pullup filter with followin ffmpeg command: ffmpeg.exe -i "sample-29.970fps.mp4" -c:v libx264 -c:a libvo_aacenc -b:a 128k -vf pullup -r 24000/1001 "sample-29.970fps_23.976fps.mp4" But result video is a bit jerky and stutter, you can see it here: http://artnmedia.pl/damian/fps/sample-29.970fps_23.976fps.mp4 Better play both of those videos in VLC, cause they both can be jerky in browser player.

[FFmpeg-user] How to change video fps from 29.970 to 25?
Hello, from a couple of days I am fighting with problem of fps conversion with ffmpeg. I discovered that conversion from 23.976fps to 25fps is easy and we can do it by speed up input video by 4%. Here I share how I did this with ffmpeg filter (maybe someone will need it too): -filter_complex "[0:v]setpts=24/25*PTS[v];[0:a]atempo=25/24[a]" -map "[v]" -map "[a]" -r 25 Converted 23.976fps video with that filter will have 25fps and playback will be smooth, great! Unfortunately I dont have idea how I can convert video from 29.970 fps to 25 using ffmpeg. I think it should be done in two steps: 1. Convert from 29.970 to 23.976. This technique is called inverse telecine(?), but I dont have idea how I can do it correctly with ffmpeg. I tried many ffmpeg filters like pullup, telecine, fieldmatch, decimate, but my output video always stuttering. Can someone help me with it? 2. Convert from 23.976 to 25 by speed up video by 4%. What do you think? Here is console output for example video which I want to convert to 25fps (but I need to convert other videos too, this one is my guinea pig): ffmpeg -i da-foundraising-foundations-29.970fps.mp4 ffmpeg version N-65895-g96b2ba6 Copyright (c) 2000-2014 the FFmpeg developers built on Aug 25 2014 22:10:37 with gcc 4.8.3 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-av isynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enab le-iconv --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca -- enable-libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable-lib modplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrw b --enable-libopenjpeg --enable-libopus --enable-librtmp --enable-libschroedinge r --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libtwolame --en able-libvidstab --enable-libvo-aacenc --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable- libx265 --enable-libxavs --enable-libxvid --enable-decklink --enable-zlib libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 0.101 / 56. 0.101 libavformat56. 3.100 / 56. 3.100 libavdevice56. 0.100 / 56. 0.100 libavfilter 5. 0.103 / 5. 0.103 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc53. 0.100 / 53. 0.100 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'da-foundraising-foundations-29.970fps.m p4': Metadata: major_brand : mp42 minor_version : 0 compatible_brands: mp42mp41isomavc1 creation_time : 2013-02-23 19:26:52 Duration: 00:13:28.74, start: 0.042667, bitrate: 2654 kb/s Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1280x720, 2492 kb/s, 29.97 fps, 29.97 tbr, 2997 tbn, 59.94 tbc (default) Metadata: creation_time : 2013-02-23 19:26:52 handler_name: L-SMASH Video Handler encoder : AVC Coding Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 15 7 kb/s (default) Metadata: creation_time : 2013-02-23 19:26:52 handler_name: L-SMASH Audio Handler Thank you for your time. --- Cheers! ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
