How to convert ppm to mp4 with avconv

I'm trying to convert a video.ppm to video.mp4.

I tried this :

avconv -r 1 -i Hole0.0001.mp4.ppm -r 24 Hole.mp4

avconv version 12.3, Copyright (c) 2000-2018 the Libav developers
  built on Oct  2 2019 11:39:18 with gcc 8 (GCC)
Input #0, image2, from 'Hole0.0001.mp4.ppm':
  Duration: 00:00:00.04, start: 0.000000, bitrate: N/A
    Stream #0:0: Video: ppm
      rgb24, 1310x560
      25 tbn
Stream mapping:
  Stream #0:0 -> #0:0 (ppm (native) -> mpeg4 (native))
Press ctrl-c to stop encoding
Output #0, mp4, to 'Hole.mp4':
  Metadata:
    encoder         : Lavf57.7.2
    Stream #0:0: Video: mpeg4 [ [0][0][0] / 0x0020]
      yuv420p, 1310x560, q=2-31, 200 kb/s
      24 fps, 24 tbn
    Metadata:
      encoder         : Lavc57.25.0 mpeg4
    Side data:
      cpb: bitrate max/min/avg: 0/0/200000 buffer size: 0 vbv_delay: -1
frame=    1 fps=  0 q=3.2 Lsize=      16kB time=10000000000.00 bitrate=   0.0kbits/s    
video:15kB audio:0kB other streams:0kB global headers:0kB muxing overhead: 5.397969%

then when I check my video.mp4 it doesn't work. I mean the video start and stop immediately.

272M Hole0.0001.mp4.ppm

16K Hole.mp4

The output of display Hole0.0001.mp4.ppm gives me this : enter image description here

as you can see i have 150 frames in the file Hole0.0001.mp4.ppm

Do you have any ideas ?

Thank you

Solution

  • I found this command which works but the quality of the video is terrible ..

    avconv -r 10 -vcodec ppm -f image2pipe -i Hole0.0001.mp4.ppm -r 20 Hole.mp4
