Codec issue on Zero4K:
As to your old media, use VLC or tools like mediainfo so determine what codecs are actually needed, without that information it is all guesswork.
I appreciate your input. I scanned a portion of the library and found that in fact
only the h264 and hevc files play well. The rest doesn't. Here's an excerpt of
the non-working codecs used (as per ffmpeg):
48 mpeg4 (Advanced Simple Profile) (XVID / 0x44495658) NOT OK 9 mpeg4 (Simple Profile) (mp4v / 0x7634706D) NOT OK 6 mpeg4 (Simple Profile) (XVID / 0x44495658) NOT OK 5 mpeg4 (DX50 / 0x30355844) NOT OK 4 mpeg4 (Simple Profile) (DIVX / 0x58564944) NOT OK 1 mpeg4 (Simple Profile) (xvid / 0x64697678) NOT OK 1 mpeg4 (Simple Profile) (DX50 / 0x30355844) NOT OK 7 mpeg1video NOT OK 2 msmpeg4v3 (DIV3 / 0x33564944) NOT OK 1 vp6f NOT OK
(sorry for messy alignment, the online editor insists on compressing the spaces)
The numbers in front reflect the ratio of files present in the test sample, so my problem
is the mpeg series of codecs, in particular mpeg4. I also have files where audio doesn't
work because of codec issues, but I haven't made a survey for that.
Most (all?) of these older files used to work on the Zero.
In other words, I'm looking for an upated-hardware Zero, like the Zero4K, but without
the newly introduced limitations of the Zero4K. Does that exist?
I suppose the bigger boxes are better in this regard, but I hestitate to buy a set of
them only to find out that those reject my library too.
Heavy (big) file issue on Zero:
About your suggestion with rsize/wsize for the "heavy" file issue (different from codec
issue). This is interesting, I had thought that bigger was better. For many files the
stutter is very predictable. There are a few ones which play more or less OK if I
don't touch anything, but as soon as I cause an overlay to be drawn or jump to a
different position then it goes downhill until I stop. I'll make some experiments with
your memory fragmentation suggestion.
