Using the same deepstream-app with the same configuration files, the FPS performance data shown by deepstream-app looks different for MP4 file and H264 file.

For MP4 file, the FPS hovers around 30++ fps.
**PERF: FPS 0 (Avg)
**PERF: 46.14 (45.33)
**PERF: 30.00 (33.73)
**PERF: 30.00 (32.12)
**PERF: 30.00 (31.48)
**PERF: 30.00 (31.14)
**PERF: 30.00 (30.92)
**PERF: 30.00 (30.78)
**PERF: 30.00 (30.67)
**PERF: 30.00 (30.59)
**PERF: 30.00 (30.55)
**PERF: 30.66 (30.49)
**PERF: 30.05 (30.45)
**PERF: 29.93 (30.46)
**PERF: 30.00 (30.43)
**PERF: 29.37 (30.35)
**PERF: 30.00 (30.33)
**PERF: 30.00 (30.31)
**PERF: 30.00 (30.29)
**PERF: 30.00 (30.28)
**PERF: 30.00 (30.26)

However, for H264 file, the FPS keep on increasing and showing 3-digits range.
**PERF: FPS 0 (Avg)
**PERF: 45.79 (45.39)
**PERF: 29.01 (32.78)
**PERF: 72.05 (49.92)
**PERF: 218.03 (100.85)
**PERF: 218.23 (128.09)
**PERF: 219.31 (145.39)
**PERF: 226.19 (158.22)
**PERF: 246.99 (170.37)
**PERF: 268.22 (182.13)
**PERF: 270.48 (191.58)
**PERF: 269.29 (199.19)
**PERF: 267.00 (205.19)
**PERF: 268.41 (210.29)
**PERF: 268.56 (214.70)
**PERF: 259.53 (217.80)

Is it because the FPS perf calculation in deepstream-app is not compatible for H264 file?

Hi,
The deviation looks to be from timestamp information. In h264 stream, it does no contain timestamp and frames are processed continuously. Could you set sync=false to the sinks and check again? You can set the property in config file.

#4

I have tried setting the sync=0 in the [sink] group as below but still the FPS keeps on increasing and showing 3-digit range.

[sink0]
enable=1
#1-fakesink 2-EGL
type=1
sync=0
source-id=0
gpu-id=0
nvbuf-memory-type=0

**PERF: FPS 0 (Avg)
**PERF: 188.18 (185.73)
**PERF: 218.92 (211.29)
**PERF: 218.25 (214.63)
**PERF: 220.29 (216.25)
**PERF: 240.93 (222.09)
**PERF: 258.24 (228.78)
**PERF: 270.40 (235.48)

Hi,
If you would like to render in fixed framerate, we would suggest mux the h264 stream into mp4 or mkv file, so that it has timestamp information.
