    This generates a single playlist with an m4s and m3u8 file :

    This stream does not play in chrome with video.js, and only plays in bitmovin client, but it constantly fails with buffer append/stalled errors. In firefox it plays, but without much reliability.

    So what am I doing wrong in this process ? I’ve checked the specification for HLS several times, can’t see what I’m doing wrong, or what the player expects.

    Please check hls.js player, with the following URL which uses the stream above to see what I’m talking about.

  • Streaming video .mp4 H.264 baseline not working on some videos [duplicate]

    8 janvier 2019, par D. B.

    This question already has an answer here :

    I use server to stream recorder videos on Android phones and play them in Android app later. However I noticed that I am not able to play all videos, I used ffmpeg to see if there is any difference in recorded videos and where the issue might be.
    That is an example of loading and playing video :

    I cannot see any difference in the videos characteristics. Both are baseline H.264.
    Both videos are playing in chrome when I access them via direct links, the problem is on android versions 6, 7, 8.
    There is strange thing because when I downloaded that not loading video directly and put in the android app to raw folder and played it directly everything worked perfectly.
    I checked if the problem was bandwidth, so I uploaded bigger video about 12Mbs, mp4 as well H.264 Main and then streamed it to the app and it worked like a charm. So I suspect that the issue might be with recording bigger files within my android app.
    To stream video I only use MediaPlayer.

    That is an example of the video I uploaded and later streamed :

Is there any chance that my hosting provider uses some kind of software that can manipulate data that is on the server?

    I also check manually other videos from different websites by inserting links manually in the code to check if MediaPlayer works correctly and every video was playing.

  • FFMPEG streaming ip cam get delay from start record to first frame

    4 janvier 2019, par Vincent Carretero

    I’m recording stream from IP CAM with FFMPEG.
    I would like to know the exact timestamp when start the output video.

    Example :
    I have an output mp4 file created at 2019/01/04 09:10:15 (file created).
    FFMpeg take few seconds to really start streaming (initialising, etc...)
    The first frame really start at 2019/01/04 09:10:19 (just supposed, I would like to get this info).

    Thanks !
