* examples/hw_decode: Use hw-config information to find pixfmtMark Thompson2017-11-291-32/+22
| | | | This removes all remaining device-type specificity.

* avcodec/samidec: check av_strdup() return valuePan Bian2017-11-291-0/+3
| | | | | | | | In function sami_paragraph_to_ass(), the return value of av_strdup() is not checked. To avoid potential NULL dereference, the return value should be checked against NULL. Signed-off-by: Pan Bian <bianpan2016@163.com>

* vp9_parser: don't split superframes into separate packetswm42017-11-291-117/+10
| | | | | We did this for the sake of the decoder. With the vp9 change, it's not necessary anymore.
* vp9: use superframe split BSFwm42017-11-292-1/+2
| | | | | | | | | | | | | | | webm usually has invisible superframes merged with normal frames. (vpxenc muxes them in this form, which is evidence enough that this is the standard webm packet format. It's rather unclear whether ffmpeg is even allowed to remux them with split packets.) The vp9 decoder needs them to be in separate packets for multithreading to work. Add the BSF to the decoder, so the conversion happens automatically. This contains the important part of fa1749dd34c55fb9, which was apparently skipped in commit d417e95af76. This restores Libav API compatibility.

| | | | | | | | | In function process_output_surface(), the return value is 0 on the path that av_mallocz() returns a NULL pointer. 0 indicates success, which deviates from the fact.

| | | | | | | | | | | | Writes one set of field framing information for progressive streams and two sets for interlaced streams. Fixes ticket #6383. Unfortunately the OpenDML v1.02 document is not very specific on what value to use for start_line when frame data is not coming from a capturing device, so this is just using 0/1 depending on the field order as a best-effort guess.

* avcodec/nvdec: More effort to make vp8 compile with gcc < 4.6Philip Langdale2017-11-261-11/+10
| | | | | | | | | | | I'm told my prefix work-around wasn't enough to make it compile, although I'm not sure why; I did some basic testing and that approach appeared to work, but I'm not in a position to do a full compile on CentOS 6 so I can't be sure of anything. I have had it confirmed that the additional change to not use named initialisers is enough to make it compile, so let's throw that into the mix too.
* avcodec/nvdec: Make vp8 initialisation more 'compatible'Philip Langdale2017-11-261-5/+14
| | | | | | | | | | | | | | | | | Ancient versions of gcc (pre 4.6) can't directly initialise members of anonymous inner unions/structs by name. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676 Unfortunately, RHEL 6 shipped with one of these ancient versions and so we're stuck with it until approximately the heat death of the universe. Putting explicit braces into the initialisation is possibly a work-around but the behaviour there was never fully understood before direct initialisation was made to work. So, this may or may not work.
