Why is ffmpeg start time non-zero in .ts format ?

22 janvier 2014, par geekydel

I'm using ffmpeg to transcode video to .ts format, and I am getting unexpected start times in the output file.

To simplify things, I've started with a nice simple AVI file (no audio) :

ffmpeg -i in.avi 

...

Input #0, avi, from &#39;in.avi&#39;:

  Metadata:

    encoder         : Lavf55.25.100

  Duration: 00:00:05.00, start: 0.000000, bitrate: 448 kb/s

    Stream #0:0: Video: mpeg4 (Simple Profile) (FMP4 / 0x34504D46), yuv420p, 480x270 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc

Duration=5s, startTime=0s, as expected.

However, if I transcode to .ts file, with no customisation :

ffmpeg -i in.avi -y out.ts

...

Input #0, avi, from &#39;in.avi&#39;:

  Metadata:

    encoder         : Lavf55.25.100

    Stream #0:0: Video: mpeg4 (Simple Profile) (FMP4 / 0x34504D46), yuv420p, 480x270 [SAR 1:1 DAR 16:9], 24 tbr, 24 tbn, 24 tbc

Output #0, mpegts, to &#39;out.ts&#39;:

  Metadata:

    Stream #0:0: Video: mpeg2video, yuv420p, 480x270 [SAR 1:1 DAR 16:9], q=2-31, 200 kb/s, 90k tbn, 24 tbc

Stream mapping:

  Stream #0:0 -> #0:0 (mpeg4 -> mpeg2video)

Press [q] to stop, [?] for help

Then I get a very odd parameters (Duration=4:96s, startTime=1.441667) :

ffmpeg -i out.ts

...

Input #0, mpegts, from &#39;out.ts&#39;:

Now, I can just about understand why the transcode might lose a couple of frames, which explains the duration, but I can't see why the start time should be any different to the AVI file's start time.

I have tried transcoding to .mp4, .webm and .mov, and in each case we get the 'correct' start time of 0.0s. Can anybody help explain why .ts files behave differently ?

Thanks in advance !

FFMPEG Video Cropping slower [duplicate]

23 juin 2016, par syed imty

This question already has an answer here :

Fast Video Compression on Android

I am trying to crop rectangular video into a square one using FFMPEG. The video conversion take too much time.

For a video of 30 secs, it takes around 60-70secs to convert

FFMPEG Command

String commandStr =" -i "+videoPath+"  -vcodec libx264 -b:v 880k -vf crop=" + videoSize.height + ":"+ videoSize.height + ":" + cropStart +":0 -preset ultrafast -strict -2 " +compressedVideoPath;

ffmpeg stops randomly with "No more output streams to write to, finishing" when reading rtsp stream [on hold]

The problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks
