datatype of padding, remove_before and remove_after

The datatype of padding, remove_before and remove_after is int. This only allows for adjustments in whole seconds.

Can this be changed to a datatype that will allow fractions of seconds (double ?) to enable finer adjustments?

Add time of first keyframe

I'm using comskip as the source times for editing MPEG2 files generated by TVheadend. I use ffmpeg to seek to an exact time (https://trac.ffmpeg.org/wiki/Seeking), but the times in the .edl file are off by the time of the first keyframe. I can use ffprobe, or other tools, to find the time of the fir...

Re: Linux Hardware Decoding

Hardware decoding does work on linux, for at least some hardware.

It works on Raspberry Pi ... viewtopic.php?f=4&t=1806

Re: Raspberry Pi mpeg2_mmal (hardware) decode

Generally agree. It should be obvious that you can't hardware decode on a device that has a locked decoder. The issue with not enough memory on the other hand should tested. I've read from people in the RPi forums who claim to run the hw decoder on just 64 MB video memory. That may or may not be tr...

Re: Raspberry Pi mpeg2_mmal (hardware) decode

Even if the mmal codecs are present, it may not always be correct to use them on all Raspberry Pis It may be possible that there is no MPEG-2 licence. I've not tested, but I'm pretty sure mpeg2_mmal won't work in this case. If there is not enough memory allocated to the GPU, using the mpeg2_mmal cod...

Raspberry Pi mpeg2_mmal (hardware) decode

Comskip should have the option to use mpeg2_mmal decoder on a Raspberry Pi. For myself, I made the following change to the source code ... mpeg2dec.c Old codec = avcodec_find_decoder(codecCtx->codec_id); New if (codecCtx->codec_id == AV_CODEC_ID_MPEG2VIDEO) { codec = avcodec_find_decoder_by_name("mp...
