Description

I am using stable "HTS Tvheadend 4.2.8-36~g5bdcfd8ac" on a Raspberry PI4, Buster OS.

I am trying to use the hardware accelerated video codec "h264_omx: OpenMAX IL H.264 video encoder" with DVB-T/2 output from the RPI Top Hat, but experience problems with aspect ratio on all SD channels.

For example, these channels playback in 4:3 rater than 16:9;

2020-02-15 08:18:32.380 transcode: 0020: 1:MPEG2VIDEO 704x576 ==> H264 704x576 (h264_omx) ----- (BBC ONE)

2020-02-15 08:27:19.572 transcode: 0023: 1:MPEG2VIDEO 544x576 ==> H264 544x576 (h264_omx) ----- (Sky News)
2020-02-15 08:29:24.930 transcode: 0024: 1:MPEG2VIDEO 720x576 ==> H264 720x576 (h264_omx) ----- (ITV)

How can this codec be changed to display correctly at 16:9 please?

By the way, if I use the Video codec "libx264: libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10", the aspect ratio is correct.

For completeness, I attach the TVH log.
