Hi all, I am using Windows 7 64 bit, and I downloaded the 64 bit version of ffmpeg: ffmpeg-20140916-git-b76d613-win64-static.7z
I have spent the entire day experimenting with ffmpeg today but I haven't quite figure out if ffmpeg is the right solution to my problem yet, so I would like to get some opinions. I am receiving H264 encoded packets through RTP with sample rate of 90,000, and I need to record these packets. The file format doesn't really matter at this point. Currently, I have a server sending the H264 packets to port 50002 of my machine (192.168.1.200), so I run the following ffmpeg command on my machine: ffmpeg -i udp://192.168.1.200:50002 -f mp4 hello.mp4 Then the following shows ffmpeg version N-66289-gb76d613 Copyright (c) 2000-2014 the FFmpeg developers built on Sep 15 2014 22:11:04 with gcc 4.8.3 (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-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-decklink --enable-zlib libavutil 54. 7.100 / 54. 7.100 libavcodec 56. 1.100 / 56. 1.100 libavformat 56. 4.101 / 56. 4.101 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 1.100 / 5. 1.100 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 The server starts sending video packets, and nothing happens on the command prompt with the ffmpeg command. The server stops sending video packets, and nothing happens still (I waited for at least 5 minutes), so I pressed Ctrl+C, then I see this udp://192.168.1.200:50002: Invalid data found when processing input Received signal 2: terminating. am I using ffmpeg correctly? and are the H264 packets I am receiving not supported? I have looked around and did not see any debug log generated by ffmpeg, so I don't really know where else to look. If it is necessary, I can provide a packet capture with the H264 packets. Thanks in advance. AL _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
