License question

30 Nov '17

Hello, We want to integrate ffmpeg.exe in our application to convert an MP4 to an low resolution MP4 and a view file in JPEG format. Also, we want to deliver ffmpeg.exe with our installer package. On https://ffmpeg.org/legal.html we only find a License Compliance Check if we compile FFmpeg and bind against the DLL. We want to use the downloadable windows executable and call the program for converting purpose. So what must we do to be save against the License Compliance.

FFmpeg Hall of Shame
by Thirumalaisamy K 29 Nov '17

29 Nov '17

According to LGPL / GPL it's necessary to provide the complete source codes which includes the objects that linked against and scripts that controls the compilation & installation. But, the websites linked in official download pages are not providing the complete sources. Only just leaving the link for the official ffmpeg sources. I have mailed to some of them. I have got the reply from one of them (evermeet.cx) that It's not necessary to provide the build scripts & claimed it's made from his own hard works and asked ffmpeg devs to contact him. It's quite unfortunate to see this response from the maintainer of a officially recommended download location. People are utilizing the hard work behind ffmpeg & refuses to comply with LGPL. It's shame. And ffmpeg team recommends such download locations. Any comments from ffmpeg dev team?

HEVC Conformance Test Failed
by Zhenan Lin 29 Nov '17

29 Nov '17

Hi, experts & developers: We use FFmpeg 3.4 to decode HEVC conformance bitstreams ( http://wftp3.itu.int/av-arch/jctvc-site/bitstream_exchange/draft_conformanc…) and only to find that 4 bitstreams got error ouput and 1 bitstream failed to decoded. The command as follows: ffmpeg -threads 1 -cpuflags 0 -i <INPUT> -f md5 - The output md5 is compared to reference software HM 16.9( http://www.hevc.info/)'s and expected to be the same.

sending RTSP/RTP onvif data stream to file
by Tom Hodder 29 Nov '17

29 Nov '17

Hi, I have several IP Cameras that stream RTSP video, but also provide Motion detects events as a metadata stream. I'd like to capture that txt to a file, however I don't seem to be able to find a combination of of codecs that outputs the xml (though I can see the xml data in the dump hex output of ffmpeg) Any suggestions on whether this is possible? Thanks, Tom I can dump the data from the RTP "data" stream, and see the xml events - but nothing is saved to the output file; ffmpeg -loglevel verbose -hide_banner -t 10 -dump -hex -allowed_media_types data -i 'rtsp:// 192.168.0.32:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif' -map 0:d -f data -c copy out.dat -y ... stream #0: 0kB time=00:00:00.00 bitrate=N/A speed= 0x keyframe=0 duration=0.000 dts=0.000 pts=0.000 size=1086 00000000 3c 3f 78 6d 6c 20 76 65 72 73 69 6f 6e 3d 22 31 <?xml version="1 00000010 2e 30 22 20 65 6e 63 6f 64 69 6e 67 3d 22 75 74 .0" encoding="ut 00000020 66 2d 38 22 20 73 74 61 6e 64 61 6c 6f 6e 65 3d f-8" standalone= 00000030 22 79 65 73 22 20 3f 3e 3c 74 74 3a 4d 65 74 61 "yes" ?><tt:Meta 00000040 44 61 74 61 53 74 72 65 61 6d 20 78 6d 6c 6e 73 DataStream xmlns 00000050 3a 74 74 3d 22 68 74 74 70 3a 2f 2f 77 77 77 2e :tt="http://www. 00000060 6f 6e 76 69 66 2e 6f 72 67 2f 76 65 72 31 30 2f onvif.org/ver10/ 00000070 73 63 68 65 6d 61 22 20 78 6d 6c 6e 73 3a 77 73 schema" xmlns:ws The metadata info in the SDP data; v=0 o=- 2251997230 2251997230 IN IP4 0.0.0.0 s=RTSP Session/2.0 c=IN IP4 0.0.0.0 t=0 0 a=control:* a=range:npt=now- a=packetization-supported:DH m=video 0 RTP/AVP 96 a=control:trackID=0 a=framerate:1.000000 a=rtpmap:96 H264/90000 a=fmtp:96 packetization-mode=1;profile-level-id=4D0029;sprop-parameter-sets=Z00AKZpmA8ARPy4C1AQEBQAAAwPoAAAH0IQ=,aO48gA== a=recvonly m=application 0 RTP/AVP 107 a=control:trackID=1 a=rtpmap:107 vnd.onvif.metadata/90000 <<<<<< ONVIF METADATA a=recvonly Probing the data shows that the 2 streams are detected; ffprobe -hide_banner -show_format 'rtsp:// 92.168.0.32:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif ' Input #0, rtsp, from 'rtsp:// 192.168.0.32:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif ': Metadata: title : RTSP Session/2.0 Duration: N/A, start: 0.000000, bitrate: N/A Stream #0:0: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 1920x1080 [SAR 1:1 DAR 16:9], 50 tbr, 90k tbn, 90k tbc Stream #0:1: Data: none Unsupported codec with id 0 for input stream 1 [FORMAT] filename=rtsp:// 192.168.0.32:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif nb_streams=2 nb_programs=0 format_name=rtsp format_long_name=RTSP input start_time=0.000000 duration=N/A size=N/A bit_rate=N/A probe_score=100 TAG:title=RTSP Session/2.0 [/FORMAT]

SDL2 over x11: “SDL: could not set video mode - exiting”
by Jeff 29 Nov '17

29 Nov '17

I’m sorry if this is covered somewhere else, but I can’t seem to find a solution on this mailing list, the SDL2 forums, or through google searches anywhere. This seems to be somewhat common, but again, no definitive solution. When I try to run a SDL2 application (e.g., ffplay) over X11 via SSH and Exceed, I receive the following error: “*SDL: could not set video mode - exiting*”. This only occurs with SDL2 applications (I’ve tried glxgears as well). Non-SDL, X-Windows applications work fine over the connection (e.g., terminal, xclock, etc). I’m able to launch ffplay locally on the machine itself, so it just fails over SSH forwarding. The DISPLAY variable is set properly (and works for other apps as mentioned). I’ve tried setting the *SDL_VIDEODRIVER to x11* as well, but still no luck. Is there something I’m missing? I have all the X11 (and DEVEL) libraries installed. SDL2 was configured with the standard ./configure options and shows X11 support in the config file. Someone on the SDL forum suggested it might be trying to use OpenGL vs. the default X11 driver and that could be the root of the issue, but I don't think so, nor do I know how to verify this. Please advise. Thank you for your time. J

Hi Carl and Moritz, Thanks for your assist earlier on, but still the solution couldn't work out. I'm not using a pre-installed binary. The binary should have been created when I initially run ./configure without any parameters. Now I run the following commands: ./configure --enable-gpl --enable-libmp3lame make install Attached are the results of the command line execution. I would like to highlight the ffmpeg folder does not contain the libmp3lame subfolder; could this be the problem?

AVC3 -> AVC1 conversion

Thank you all your responses. However, I for me the "-tag:v avc1" approach didn't work. Starting with input.mp4 which is shown as Duration: 00:42:08.08, start: 0.000000, bitrate: 941 kb/s Stream #0:0(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 125 kb/s (default) Metadata: handler_name : SoundHandler Stream #0:1(und): Video: h264 (Main) (avc3 / 0x33637661), yuv420p(tv, bt709), 704x396 [SAR 1:1 DAR 16:9], 811 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:2: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 192x108 [SAR 72:72 DAR 16:9], 90k tbr, 90k tbn, 90k tbc I ran: % ffmpeg -i input.mp4 -c copy -tag:v avc1 output.mp4 and the resulting file output.mp4 was reported as: Duration: 00:42:08.08, start: 0.000000, bitrate: 941 kb/s Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuv420p(tv, bt709), 704x396 [SAR 1:1 DAR 16:9], 811 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:1(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 125 kb/s (default) Metadata: handler_name : SoundHandler However Quicktime/iTunes/Preview all couldn't play this file (e.g. preview opens a window with a spinning wheel in the middle and goes no further). What *has* worked for me is: % ffmpeg -i input.mp4 -codec copy -bsf:v h264_mp4toannexb output.ts % ffmpeg -i input.ts -codec copy output.mp4 I hope this is useful for someone else in the future. Thanks Ant.

Splicing together videos with different characteristics
by Full Name 28 Nov '17

28 Nov '17

I have a series of videos of my daughter giving piano recitals over the years. The videos start when she was very little, playing with a single finger, till now, that she can play the piano with high proficiency. I would like to splice them together into a single video. The problem is that the first few videos were obtained with an older camcorder, that could do 640x480 resolution, whereas the later ones were captured with a newer camcorder, able to do 1920x1080 resolution. At some point I used a combination of HandBrake and ffmpeg to splice them together, but with incomplete success, in that the aspect ratio of the 1920x1080 videos was modified to match that of the 640x480 ones. The end result was, of course, very unsatisfactory. I was wondering if ffmpeg might allow me to obtain better results. Is at all possible, with ffmpeg, to splice such videos together, so that the correct aspect ration is maintained for all the portions in the final video? I would have thought that the answer is 'no', but my knowledge of these things is very shallow. More in general, what I would like from experts in this forum is advice on how to splice together the videos above, in order to get the best results, using ffmpeg.

AVC3 -> AVC1 conversion

Hello, I've recently received some H264 videos marked as AVC3: Duration: 00:29:00.00, start: 0.000000, bitrate: 949 kb/s Stream #0:0(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 125 kb/s (default) Metadata: handler_name : SoundHandler Stream #0:1(und): Video: h264 (Main) (avc3 / 0x33637661), yuvj420p(pc, bt709), 704x396 [SAR 1:1 DAR 16:9], 819 kb/s, 25 fps, 25 tbr, 25k tbn, 50 tbc (default) Metadata: handler_name : VideoHandler Stream #0:2: Video: mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 192x108 [SAR 72:72 DAR 16:9], 90k tbr, 90k tbn, 90k tbc These are not natively playable by quicktime/iTunes under OSX High Sierra (10.13.1). I can obviously convert them into H264 avc1 the long way, but wondered if there was a quick way of simply changing the metadata of the avc3 stream into avc1? I've tried splitting the audio and video into two streams, and then remuxing. This worked, but the video was "jerky" and unwatchable. Thanks for your help. Ant.
