Reland "Reland "Update video_quality_analysis to align videos instead of using barcodes""
This is a reland of 9bb55fc09b6bfa00cba7779c37ad6c39b4206f7a Original change's description: > Reland "Update video_quality_analysis to align videos instead of using barcodes" > > This is a reland of d65e143801a7aaa9affdb939ea836aec1955cdcc > > The binary for frame_analyzer.cpp is precompiled and stored in the cloud, so it > won't automatically pick up change to the source file. Therefore, restore all > old code to be backwards compatible. > > Original change's description: > > Update video_quality_analysis to align videos instead of using barcodes > > > > This CL is a follow-up to the previous CL > > https://webrtc-review.googlesource.com/c/src/+/94773 that added generic > > logic for aligning videos. This will allow us to easily extend > > video_quality_analysis with new sophisticated video quality metrics. > > Also, we can use any kind of video that does not necessarily need to > > contain bar codes. Removing the need to decode barcodes also leads to a > > big speedup for the tests. > > > > Bug: webrtc:9642 > > Change-Id: I74b0d630b3e1ed44781ad024115ded3143e28f50 > > Reviewed-on: https://webrtc-review.googlesource.com/94845 > > Reviewed-by: Paulina Hensman <phensman@webrtc.org> > > Reviewed-by: Patrik Höglund <phoglund@webrtc.org> > > Commit-Queue: Magnus Jedvert <magjed@webrtc.org> > > Cr-Commit-Position: refs/heads/master@{#24423} > > TBR=phensman@webrtc.org,phoglund@webrtc.org > > Bug: webrtc:9642 > Change-Id: Id8d129ce103284504c67690f8363c03eaae3eee7 > Reviewed-on: https://webrtc-review.googlesource.com/96000 > Reviewed-by: Magnus Jedvert <magjed@webrtc.org> > Reviewed-by: Patrik Höglund <phoglund@webrtc.org> > Commit-Queue: Magnus Jedvert <magjed@webrtc.org> > Cr-Commit-Position: refs/heads/master@{#24429} TBR=phensman,phoglund Bug: webrtc:9642 Change-Id: Ic248b7831ae148251a1a4ebeec5d154286f91a0a Reviewed-on: https://webrtc-review.googlesource.com/98080 Commit-Queue: Magnus Jedvert <magjed@webrtc.org> Reviewed-by: Patrik Höglund <phoglund@webrtc.org> Reviewed-by: Magnus Jedvert <magjed@webrtc.org> Cr-Commit-Position: refs/heads/master@{#24583}

* A command line tool running PSNR and SSIM on a reference video and a test
|
||||
* video. The test video is a record of the reference video which can start at
|
||||
* an arbitrary point. It is possible that there will be repeated frames or
|
||||
* skipped frames as well. In order to have a way to compare corresponding
|
||||
* frames from the two videos, two stats files should be provided. One for the
|
||||
* reference video and one for the test video. The stats file
|
||||
* is a text file assumed to be in the format:
|
||||
* frame_xxxx yyyy where xxxx is the frame number in and yyyy is the
|
||||
* corresponding barcode. The video files should be 1420 YUV videos.
|
||||
* The tool prints the result to standard output in the Chromium perf format:
|
||||
* skipped frames as well. The video files should be I420 .y4m or .yuv videos.
|
||||
* If both files are .y4m, it's not needed to specify width/height. The tool
|
||||
* prints the result to standard output in the Chromium perf format:
|
||||
* RESULT <metric>:<label>= <values>
|
||||
*
|
||||
* The max value for PSNR is 48.0 (between equal frames), as for SSIM it is 1.0.
|
||||
*
|
||||
* Usage:
|
||||
* frame_analyzer --label=<test_label> --reference_file=<name_of_file>
|
||||
* --test_file_ref=<name_of_file> --stats_file_test=<name_of_file>
|
||||
* --stats_file=<name_of_file> --width=<frame_width>
|
||||
* --height=<frame_height>
