  • What is wrong with mjpeg stream, ffserver and ffplay ?

    9 septembre 2013, par Ilya Yevlampiev

    I'm creating mjpeg stream from image files using ffmpeg and write it to ffserver's feed :

    sudo ffmpeg -loop 1 -i fon.jpeg -vcodec mjpeg -f mjpeg http://localhost:8090/feed1.ffm

  • Seeking with FFMPEG at the end of an RTSP stream

    30 juillet 2019, par kealist

    I am using ffmpeg to play RTSP streams in an application. I have been running into a problem that once I reach the end of an RTSP stream, I am no longer able to see back to anywhere in the stream.

    The program I am writing is using LGPL shared libraries, but I can see the same behavior using ffplay using GPL version.

    ffplay.exe "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov"

    While the video is playing, I can seek forward or backwards using the keyboard shortcuts for ffplay (left / right arrow key). Once the stream reaches the end, it is not possible and the stream is paused or playing, seeking no longer works. I see errors in the shared lib, but in ffplay, I do not see errors unless I use the s key (which may make sense that I cannot seek). In other streams, I have seen an issue where the stream is longer than the reported length, and once the extra video is buffered/downloaded, it is not possible to seek. Any guidance on what is going on here ?

    Using ffplay.exe (also verified with newer build) :

    C:\Users\kealist\Downloads\ffmpeg-20180526-63c4a4b-win64-static\bin>ffplay "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov"

  • FFMPEG Error while opening decoder for input stream

    While this command his been working for a couple of months, I suddenly began running into the following error when encoding video via my php application.

Error while opening decoder for input stream #0:0

    I have uninstalled ffmpeg, recompiled from source, also recompiled x264 and a host of other libraries, but this error persists. Is there anyway I can find out more about what exactly is failing ?
